Summary Of Significant Accounti

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Organization and Nature of Operations. Tredegar Corporation and subsidiaries (collectively “Tredegar,” “the Company,” “we,” “us” or “our”) are primarily engaged in the manufacture of polyethylene films, polyester films and aluminum extrusions. See Notes 10 and 18 regarding restructurings and Note 3 regarding discontinued operations. Basis of Presentation. The consolidated financial statements include the accounts and operations of Tredegar and all of its majority-owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. On February 12, 2008, Tredegar sold its aluminum extrusions business in Canada. All historical results for this business have been reflected as discontinued operations in these financial statements; however, cash flows for discontinued operations have not been separately disclosed in the consolidated statements of cash flows. See Note 3 regarding discontinued operations. The preparation of financial statements in conformity with United States (“U.S.”) generally accepted accounting principles (“U.S. GAAP”) requires Tredegar to make estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. Tredegar has historically reported two business segments: Film Products and Aluminum Extrusions. In the third quarter of 2015, the Company divided Film Products into two separate operating segments: PE Films and Flexible Packaging Films. All historical results for PE Films and Flexible Packaging Films have been separately presented to conform with the new presentation of segments. See Note 5 regarding business segments. Certain amounts for the prior years have been reclassified to conform to current year presentation. Foreign Currency Translation. The financial statements of subsidiaries located outside the U.S., where the local currency is the functional currency, are translated into U.S. Dollars using exchange rates in effect at the period end for assets and liabilities and average exchange rates during each reporting period for results of operations. Adjustments resulting from the translation of these financial statements are reflected as a separate component of shareholders’ equity. There are no operating subsidiaries located outside the U.S. where the U.S. Dollar is the functional currency. Transaction and remeasurement gains or losses included in income were losses of $4.0 million , $1.5 million and $0.4 million in 2015 , 2014 and 2013 , respectively. These amounts do not include the effects between reporting periods that exchange rate changes have on income of the locations outside the U.S. that result from translation into U.S. Dollars. Cash and Cash Equivalents. Cash and cash equivalents consist of cash on hand in excess of daily operating requirements and highly liquid investments with original maturities of three months or less. At December 31, 2015 and 2014 , Tredegar had cash and cash equivalents of $44.2 million and $50.1 million , respectively, including funds held in locations outside the U.S. of $27.7 million and $40.5 million , respectively. The Company’s policy permits investment of excess cash in marketable securities that have the highest credit ratings and maturities of less than one year. The primary objectives of the policy are safety of principal and liquidity. Accounts and Other Receivables. Accounts receivable are stated at the amount invoiced to customers less allowances for doubtful accounts and sales returns. Accounts receivable are non-interest bearing and arise from the sale of product to customers under typical industry trade terms. Notes receivable are not significant. Past due amounts are determined based on established terms and charged-off when deemed uncollectible. The allowance for doubtful accounts is determined based on an assessment of probable losses taking into account past due amounts, customer credit profile, historical experience and current economic conditions. Other receivables include value-added taxes related to certain foreign subsidiaries and other miscellaneous receivables due within one year. Inventories. Inventories are stated at the lower of cost or market, with cost determined on the last-in, first-out (“LIFO”) basis, the weighted average cost or the first-in, first-out basis. Cost elements included in work-in-process and finished goods inventories are raw materials, direct labor and manufacturing overhead. Finished goods, work in process, raw materials and supplies, stores and other inventory are reviewed to determine if inventory quantities are in excess of forecasted usage or if they have become obsolete. Property, Plant and Equipment. Accounts include costs of assets constructed or purchased, related delivery and installation costs and interest incurred on significant capital projects during their construction periods. Expenditures for renewals and betterments also are capitalized, but expenditures for repairs and maintenance are expensed as incurred. The cost and accumulated depreciation applicable to assets retired or sold are removed from the respective accounts, and gains or losses thereon are included in income. Capital expenditures for property, plant and equipment include capitalized interest. Capitalized interest included in capital expenditures for property, plant and equipment was $0.4 million , $1.1 million and $0.9 million in 2015 , 2014 and 2013 , respectively. Depreciation is computed primarily by the straight-line method based on the estimated useful lives of the assets that, except for isolated exceptions, range from 5 to 40 years for buildings and land improvements and 2 to 20 years for machinery and equipment. Investments in Private Entities with Less Than or Equal to 50% Voting Ownership Interest. The Company accounts for its investments in private entities where its voting ownership is less than or equal to 50% based on the facts and circumstances surrounding the investment. Investments are required to be accounted for under the consolidation method in situations where Tredegar is the primary beneficiary of a variable interest entity. The primary beneficiary is the party that has a controlling financial interest in a variable interest entity. The Company is deemed to have a controlling financial interest if it has (i) the power to direct activities of the variable interest entity that most significantly impact its economic performance and (ii) the obligation to absorb losses or the right to receive benefits from the variable interest entity that could potentially be significant to its operations. If the Company is not deemed to be the primary beneficiary in an investment in a variable interest entity then it selects either: (i) the fair value method or (ii) either (a) the cost method if it does not have significant influence over operating and financial policies of the investee or (b) the equity method if it does have significant influence. For those investments measured at fair value, U.S. GAAP requires disclosure of the level within the fair value hierarchy in which fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets or liabilities (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3). Goodwill and Other Intangibles. The excess of the purchase price over the fair value of identifiable net assets of acquired companies is allocated to goodwill. The Company assesses goodwill for impairment when events or circumstances indicate that the carrying value may not be recoverable or, at a minimum, on an annual basis (December 1 of each year). The Company recorded a goodwill impairment charge of $ 44.5 million ( $44.5 million after taxes) to write off the goodwill associated with Flexible Packaging Films in the third quarter of 2015. See Note 8 for additional details. The Company estimates the fair value of its reporting units using discounted cash flow analysis and comparative enterprise value-to-EBITDA (earnings before interest, taxes, depreciation and amortization) multiples. The remaining goodwill were tested for impairment at the annual testing date, with the estimated fair value of these reporting units substantially exceeding the carrying value of its net assets. Indefinite-lived intangible assets are assessed for impairment when events or circumstances indicate that the carrying value may not be recoverable, or, at a minimum, on an annual basis (December 1st of each year). The Company estimates the fair value of its trade names using a relief-from-royalty method that relies upon a corresponding discounted cash flow analysis. The indefinite-lived intangible assets were tested for impairment at the annual testing date, with the estimated fair value substantially exceeding the carrying value of the net assets. Impairment of Long-Lived Assets. The Company reviews long-lived assets for possible impairment when events indicate that an impairment may exist. For assets that are held and used in operations, if events indicate that an asset may be impaired, the Company estimates the future unlevered pre-tax cash flows expected to result from the use of the asset and its eventual disposition. Assets are grouped for this purpose at the lowest level for which there are identifiable and independent cash flows. If the sum of these undiscounted pre-tax cash flows is less than the carrying amount of the asset, an impairment loss is calculated. Measurement of the impairment loss is the amount by which the carrying amount exceeds the estimated fair value of the asset group. Assets that are held for sale are reported at the lower of their carrying amount or estimated fair value less cost to sell, with an impairment loss recognized for any write-down required. Pension Costs and Postretirement Benefit Costs Other than Pensions. Pension costs and postretirement benefit costs other than pensions are accrued over the period employees provide service to Tredegar. Liabilities and expenses for pension plans and other postretirement benefits are determined using actuarial methodologies and incorporate significant assumptions, including the rate used to discount the future estimated liability, the long-term rate of return on plan assets, and several assumptions relating to the employee workforce. The Company recognizes the funded status of its pension and other postretirement plans in the accompanying consolidated balance sheets. Tredegar’s policy is to fund its pension plans at amounts not less than the minimum requirements of the Employee Retirement Income Security Act (“ERISA”) of 1974 and to fund postretirement benefits other than pensions when claims are incurred. Revenue Recognition. Revenue from the sale of products, which is shown net of estimated sales returns and allowances, is recognized when title has passed to the customer, the price of the product is fixed and determinable, and collectability is reasonably assured. Amounts billed to customers related to freight have been classified as sales in the accompanying consolidated statements of income. The cost of freight has been classified as a separate line in the accompanying consolidated statements of income. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction between Tredegar and its customers (such as value-added taxes) are accounted for on a net basis and therefore excluded from revenues. Research & Development (“R&D”) Costs. R&D costs are expensed as incurred and include primarily salaries, wages, employee benefits, equipment depreciation, facility costs and the cost of materials consumed relating to R&D efforts. R&D costs include a reasonable allocation of indirect costs. Income Taxes. Income taxes are recognized during the period in which transactions enter into the determination of income for financial reporting purposes, with deferred income taxes being provided at enacted statutory tax rates on the differences between the financial reporting and tax bases of assets and liabilities (see Note 17). Deferred U.S. federal income taxes have not been recorded for the undistributed earnings for Terphane Holdings, LLC (“Terphane”) because of the Company’s intent to permanently reinvest these earnings. Because of the accumulation of significant losses related to foreign currency translations at Terphane as of December 31, 2015 , there were no unrecorded deferred tax liabilities associated with the U.S. federal income taxes and foreign withholding taxes on undistributed earnings indefinitely invested outside the U.S. The Company accrues U.S. federal income taxes to the extent required under U.S. GAAP on unremitted earnings of all other foreign subsidiaries. A valuation allowance is recorded in the period when the Company determines that it is more likely than not that all or a portion of deferred tax assets may not be realized. The establishment and removal of a valuation allowance requires the Company to consider all positive and negative evidence and make a judgmental decision regarding the amount of valuation allowance required as of a reporting date. The benefit of an uncertain tax position is included in the accompanying financial statements when the Company determines that it is more likely than not that the position will be sustained, based on the technical merits of the position, if the taxing authority examines the position and the dispute is litigated. This determination is made on the basis of all the facts, circumstances and information available as of the reporting date. Earnings Per Share. Basic earnings per share is computed using the weighted average number of shares of common stock outstanding. Diluted earnings per share is computed using the weighted average common and potentially dilutive common equivalent shares outstanding, determined as follows: 2015 2014 2013 Weighted average shares outstanding used to compute basic earnings per share 32,578,116 32,302,108 32,171,751 Incremental shares attributable to stock options and restricted stock — 251,746 427,528 Shares used to compute diluted earnings per share 32,578,116 32,553,854 32,599,279 Incremental shares attributable to stock options and restricted stock are computed using the average market price during the related period. The Company had a net loss from continuing operations in 2015, so there is no dilutive impact for such shares. If the Company had reported net income from continuing operations in 2015, average out-of-the-money options to purchase shares that would have been excluded from the calculation of incremental shares attributable to stock options and restricted stock were 881,513 . The average out-of-the-money options to purchase shares that were excluded from the calculation of incremental shares attributable to stock options and restricted stock were 320,849 in 2014 and 31,167 in 2013 . Stock-Based Employee Compensation Plans. Compensation expense is recorded on all share-based awards based upon its calculated fair value over the requisite service period using the graded-vesting method. The fair value of stock option awards was estimated as of the grant date using the Black-Scholes options-pricing model. The fair value of restricted stock awards was estimated as of the grant date using the closing stock price on that date. The assumptions used in this model for valuing Tredegar stock options granted in 2014 and 2013 (no grants in 2015) are as follows: 2014 2013 Dividend yield 1.3 % 1.1 % Weighted average volatility percentage 43.5 % 48.3 % Weighted average risk-free interest rate 2.0 % 1.1 % Holding period (years): Officers 6.0 6.0 Management 5.0 5.0 Weighted average exercise price at date of grant (also weighted average market price at date of grant): Officers $ 22.49 $ 24.84 Management $ 22.33 $ 25.10 The dividend yield is the actual dividend yield on Tredegar’s common stock at the date of grant, which the Company believes is a reasonable estimate of the expected yield during the holding period. The expected volatility is based on the historical volatility of Tredegar’s common stock using a sequential period of historical data equal to the expected holding period of the option. The Company has no reason to believe that future volatility for this period is likely to differ from the past. The assumed risk-free interest rate is based on observed interest rates (zero coupon U.S. Treasury debt securities) appropriate for the expected holding period. The expected holding period and forfeiture assumptions are based on historical experience. Estimated forfeiture assumptions are reviewed through the vesting period. Adjustments are made if actual forfeitures differ from previous estimates. The cumulative effect of a change in estimated forfeitures is recognized in the period of the change. Tredegar stock options granted during 2014 and 2013 (no grants in 2015), and related estimated fair value at the date of grant, are as follows: 2014 2013 Stock options granted (number of shares): Officers 87,820 94,400 Management 93,656 90,300 Total 181,476 184,700 Estimated weighted average fair value of options per share at date of grant: Officers $ 9.21 $ 10.37 Management $ 7.60 $ 9.65 Total estimated fair value of stock options granted (in thousands) $ 1,521 $ 1,850 Additional disclosure of Tredegar stock options is included in Note 13. Financial Instruments. Tredegar uses derivative financial instruments for the purpose of hedging aluminum price volatility and currency exchange rate exposures that exist as part of transactions associated with ongoing business operations. The Company’s derivative financial instruments are designated as and qualify as cash flow hedges and are recognized in the accompanying balance sheet at fair value. A change in the fair value of the derivative that is highly effective and that is designated and qualifies as a cash flow hedge is recorded in other comprehensive income. Gains and losses reported in other comprehensive income (loss) are reclassified to earnings in the periods in which earnings are affected by the variability of cash flows of the hedged transaction. Such gains and losses are reported on the same line as the underlying hedged item, and the cash flows related to financial instruments are classified in the consolidated statements of cash flows in a manner consistent with those of the transactions being hedged. Any hedge ineffectiveness (which represents the amount by which the changes in the fair value of the derivative exceed the variability in the cash flows of the forecasted transaction) is recorded in current period earnings. The amount of gains and losses recognized for hedge ineffectiveness were not material in 2015 , 2014 and 2013 . The Company’s policy requires that it formally document all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking various hedge transactions. The Company also formally assesses (both at the hedge’s inception and on an ongoing basis) whether the derivatives that are used in hedging transactions have been highly effective in offsetting changes in the fair value or cash flows of hedged items and whether those derivatives may be expected to remain highly effective in future periods. When it is determined that a derivative is not (or has ceased to be) highly effective as a hedge, the Company discontinues hedge accounting prospectively. As a policy, Tredegar does not engage in speculative or leveraged transactions, nor does it hold or issue financial instruments for trading purposes. Additional disclosure of the utilization of derivative hedging instruments is included in Note 9. Comprehensive Income (Loss). Comprehensive income (loss) is defined as net income or loss as adjusted by other comprehensive income or loss items. Other comprehensive income (loss) includes changes in foreign currency translation adjustments, unrealized gains and losses on derivative financial instruments, prior service costs and net gains or losses from pension and other postretirement benefit plans arising during the period and amortization of these prior service costs and net gain or loss adjustments, all recorded net of deferred income taxes. The following table summarizes the after-tax changes in accumulated other comprehensive income (loss) for the year ended December 31, 2015 : (In Thousands) Foreign currency translation adjustment Gain (loss) on derivative financial instruments Pension and other post-retirement benefit adjustments Total Beginning balance, January 1, 2015 $ (47,270 ) $ 656 $ (103,581 ) $ (150,195 ) Other comprehensive income (loss) before reclassifications (65,537 ) (3,221 ) (2,176 ) (70,934 ) Amounts reclassified from accumulated other comprehensive income (loss) — 2,192 10,218 12,410 Net other comprehensive income (loss) - current period (65,537 ) (1,029 ) 8,042 (58,524 ) Ending balance, December 31, 2015 $ (112,807 ) $ (373 ) $ (95,539 ) $ (208,719 ) The following table summarizes the after-tax changes in accumulated other comprehensive income (loss) for the year ended December 31, 2014 : (In Thousands) Foreign currency translation adjustment Gain (loss) on derivative financial instruments Pension and other post-retirement benefit adjustments Total Beginning balance, January 1, 2014 $ (19,205 ) $ 765 $ (71,848 ) $ (90,288 ) Other comprehensive income (loss) before reclassifications (28,065 ) 294 (38,730 ) (66,501 ) Amounts reclassified from accumulated other comprehensive income (loss) — (403 ) 6,997 6,594 Net other comprehensive income (loss) - current period (28,065 ) (109 ) (31,733 ) (59,907 ) Ending balance, December 31, 2014 $ (47,270 ) $ 656 $ (103,581 ) $ (150,195 ) Reclassifications of balances out of accumulated other comprehensive income (loss) into net income during 2015 are summarized as follows: (In Thousands) Amount reclassified from other comprehensive income (loss) Location of gain (loss) reclassified from accumulated other comprehensive income (loss) to net income (loss) Gain (loss) on derivative financial instruments: Aluminum future contracts, before taxes $ (3,538 ) Cost of sales Foreign currency forward contracts, before taxes 62 Cost of sales Total, before taxes (3,476 ) Income tax expense (benefit) (1,284 ) Income taxes Total, net of tax $ (2,192 ) Amortization of pension and other post-retirement benefits: Actuarial gain (loss) and prior service costs, before taxes $ (16,041 ) (a) Income tax expense (benefit) (5,823 ) Income taxes Total, net of tax $ (10,218 ) (a) This component of accumulated other comprehensive income is included in the computation of net periodic pension cost (see Note 14 for additional detail).

Recently Issued Accounting Standards . In May 2014, the Financial Accounting Standards Board (“FASB”) and International Accounting Standards Board (“IASB”) issued their converged standard on revenue recognition. The revised revenue standard contains principles that an entity will apply to direct the measurement of revenue and timing of when it is recognized. The core principle of the guidance is that the recognition of revenue should depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods and services. To achieve that core principle, an entity will utilize a principle-based five-step approach model. The converged standard also includes more robust disclosure requirements which will require entities to provide sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In July 2015, the FASB delayed the effective date of this revised standard to annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is permitted as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that annual reporting period. The converged standard can be adopted either retrospectively or through the use of a practical expedient. The Company is assessing the impact of this new guidance. In April 2015, the FASB issued new guidance requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct reduction from the carrying amount of that corresponding debt liability, consistent with debt discounts, rather than as a deferred charge (e.g., an asset). The new guidance did not address the presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. In August 2015, the FASB issued updated guidance that stated in the absence of authoritative guidance, debt issuance costs associated with line-of-credit arrangements could continue to be deferred and presented as an asset over the corresponding amortization period. The new guidance will be effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. The guidance requires that all prior period balance sheets be adjusted retrospectively, and early adoption is permitted. The Company expects to adopt the guidance by the first quarter of 2016. Deferred debt issuance costs associated with the Company’s Credit Agreement were $0.7 million and $1.1 million (included in “Other assets and deferred charges” in the consolidated balance sheet) at December 31, 2015 and December 31, 2014 , respectively. The Company does not anticipate that this guidance will impact its consolidated balance sheet as its current debt issuance costs are associated with a revolving credit facility. In May 2015, the FASB issued new guidance for investments measured at net asset value (“NAV”). Under the new guidance, investments measured at NAV, as a practical expedient for fair value, are excluded from the fair value hierarchy. Removing investments measured using the practical expedient from the fair value hierarchy is intended to eliminate diversity in practice that currently exists with respect to the categorization of these investments. The new guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015 for public business entities. Early adoption is permitted, including for financial statement periods that have not yet been issued. Early adoption is permitted for all entities, and the Company has chosen to early adopt this guidance on a retrospective basis. See Note 14 for additional detail. In July 2015, the FASB issued new guidance for the measurement of inventories. Inventories within the scope of the revised guidance should be measured at the lower of cost or net realizable value. The previous guidance dictated that inventory should be measured at the lower of cost or market, with market being either replacement cost, net realizable value or net realizable value less an approximation of normal profit margin. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Subsequent measurement is unchanged for inventories measured using LIFO or the retail inventory method. The amended guidance is effective for fiscal years beginning after December 31, 2016, including the interim periods within those fiscal years. The amendments should be applied prospectively, with early adoption permitted. The Company is assessing the impact of this revised guidance. In September 2015, the FASB issued new guidance associated with accounting for adjustments to provisional amounts recognized in a business combination. To simplify the accounting for adjustments made to provisional amounts, the updated standard requires that the acquirer recognize adjustments to provisional amounts that are identified during the measurement period in the reporting period in which the adjustment amount is determined. The acquirer is required to also record, in the same period’s financial statements, the effect on earnings of changes in depreciation, amortization, or other income effects, if any, as a result of the change to the provisional amounts, calculated as if the accounting had been completed at the acquisition date. An entity is also required to present separately on the face of the income statement or disclose in the notes to the financial statements the portion of the amount recorded in current-period earnings by line item that would have been recorded in previous reporting periods if the adjustment to the provisional amounts had been recognized as of the acquisition date. The revised guidance is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years, with early adoption permitted. The amendments should be applied prospectively to adjustments to provisional amounts that occur after adoption. The Company will apply this guidance in accounting for future business combinations. In November 2015, the FASB issued new guidance associated with the classification of deferred income tax assets and liabilities in a classified statement of financial position. Current guidance requires an entity to separate deferred income tax liabilities and assets into current and noncurrent amounts in a classified statement of financial position. Deferred tax liabilities and assets are classified as current or noncurrent based on the classification of the related asset or liability for financial reporting. Deferred tax liabilities and assets that are not related to an asset or liability for financial reporting are classified according to the expected reversal date of the temporary difference. To simplify the presentation of deferred income taxes, the amended guidance requires that deferred income tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amended guidance is effective for financial statement periods beginning after December 15, 2016, and interim periods within those periods. Early application is permitted for all entities, and the Company has chosen to early adopt this guidance on a prospective basis. See Note 17 for additional detail.

Business Combinations [Abstract]
Acquisitions	ACQUISITIONS On October 1, 2012, The William L. Bonnell Company, Inc. acquired 100% ownership of AACOA, Inc. (“AACOA”). AACOA operates production facilities in Elkhart, Indiana and Niles, Michigan. Its primary markets include consumer durables, machinery and equipment and transportation. The acquisition added fabrication capabilities to Aluminum Extrusions’ array of products and services while providing AACOA with large press capabilities and enhanced geographic sales coverage in a variety of end-use markets. All post-closing adjustments related to the purchase price for AACOA were resolved in 2013. Adjustments to the purchase price were made retrospectively as if the accounting had been completed on the acquisition date. After certain post-closing adjustments (primarily related to working capital transferred), the purchase price, net of cash acquired, was $54.1 million , which includes $0.6 million that was received from the seller in 2013. The purchase price was funded using financing secured from the Company’s existing $350 million revolving credit facility.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	DISCONTINUED OPERATIONS On February 12, 2008, the Company sold its aluminum extrusions business in Canada for $25.0 million . In 2014, accruals for indemnifications under the purchase agreement related to environmental matters were adjusted, resulting in income from discontinued operations of $0.9 million ( $0.9 million net of tax). In 2013, an accrual of $14.0 million ( $14.0 million net of tax) was made for indemnifications under the purchase agreement related to environmental matters. The historical results for this business, including any subsequent adjustments for contractual indemnifications, have been reflected as discontinued operations; however, cash flows for discontinued operations have not been separately disclosed in the consolidated statements of cash flows.

Equity Method Investments and Joint Ventures [Abstract]
Investments	INVESTMENTS In August 2007 and December 2008, Tredegar made an aggregate investment of $7.5 million in kaleo, Inc. (“kaléo”), a privately held specialty pharmaceutical company dedicated to building innovative solutions for serious and life-threatening medical conditions. The mission of kaléo is to provide products that empower patients to confidently take control of their medical conditions. The Company’s ownership interest on a fully diluted basis is approximately 19% , and the investment is accounted for under the fair value method. At the time of the initial investment, the Company elected the fair value option over the equity method of accounting since its investment objectives were similar to those of venture capitalists, which typically do not have controlling financial interests. At December 31, 2015 and 2014 , the estimated fair value of the Company’s investment (included in “Other assets and deferred charges” in the consolidated balance sheets) was $18.6 million and $39.1 million , respectively. In 2009, kaléo licensed exclusive rights to sanofi-aventis U.S. LLC (“Sanofi”) to commercialize an epinephrine auto-injector in the U.S. and Canada. Sanofi began manufacturing and distributing the epinephrine auto-injector, under the names Auvi-Q ® in the U.S. and Allerject ® in Canada, in 2013. On October 28, 2015, Sanofi announced a voluntary recall of all Auvi-Q and Allerject epinephrine injectors that were currently on the market. The Company recognized an unrealized loss on its investment in kaléo of $20.5 million ( $15.7 million after taxes) in 2015 that was primarily related to the adverse impact of this product recall. The Company recognized a net unrealized gain of $2.0 million ( $1.0 million after taxes) in 2014 that primarily related to favorable adjustments in the fair value for the passage of time as anticipated cash flows associated with achieving product development and commercialization milestones were discounted at 45% for their high degree of risk and the impact of reducing the weighted average cost of capital used to discount cash flow projections after kaléo commercialized a second product, partially offset by unfavorable adjustments in the fair value due to a reassessment of the amount and timing of estimated cash flows associated with kaléo’s commercialized products. The Company recognized an unrealized gain of $3.4 million ( $2.2 million after taxes) in 2013 related to favorable adjustments in the fair value for the passage of time as anticipated cash flows associated with achieving product development and commercialization milestones were discounted at 55% for their high degree of risk, partially offset by unfavorable adjustments in the fair value due to a reassessment of the amount and timing of projected receipt of royalty and milestone payments from commercial sales of kaléo’s licensed product, which launched in early 2013, and unfavorable adjustments for higher development and commercialization expenses related to its product pipeline. Unrealized gains (losses) associated with this investment are included in “Other income (expense), net” in the consolidated statements of income and separately stated in the segment operating profit table in Note 5. Subsequent to its most recent investment (December 15, 2008), and until the next round of financing, the Company believes fair value estimates are based upon Level 3 inputs since there is no secondary market for its ownership interest. Accordingly, until the next round of financing or any other significant financial transaction, value estimates will primarily be based on assumptions relating to meeting product development and commercialization milestones, cash flow projections (projections of development and commercialization milestone payments, sales, costs, expenses, capital expenditures and working capital investment) and discounting of these factors for their high degree of risk. If kaléo does not meet its development and commercialization milestones or there are indications that the amount or timing of its projected cash flows or related risks are unfavorable versus the most recent valuation, or a new round of financing or other significant financial transaction indicates a lower enterprise value, then the Company’s estimate of the fair value of its ownership interest in kaléo is likely to decline. Adjustments to the estimated fair value of this investment will be made in the period upon which such changes can be quantified. In addition to the impact on valuation of the possible changes in assumptions, Level 3 inputs and projections from changes in business conditions, the fair market valuation of Tredegar’s interest in kaléo is sensitive to changes in the weighted average cost of capital used to discount cash flow projections for the high degree of risk associated with meeting development and commercialization milestones as anticipated. The weighted average cost of capital used in the fair market valuation of the Company’s interest in kaléo was 45% at both December 31, 2015 and 2014 . In 2015, the weighted average cost of capital used to discount cash flow projections reflected the product risk associated with Sanofi’s voluntary recall of Auvi-Q ® and Allerject ® in North America. In 2014, the weighted average cost of capital used to discount cash flow projections was decreased to reflect lower product risk after the U.S. Food and Drug Administration’s approval of kaléo’s naloxone auto-injector for emergency treatment of known or suspected opioid overdoses and reduced funding risk subsequent to kaléo securing new debt financing, both of which occurred in April 2014. At December 31, 2015 , the effect of a 500 basis point decrease in the weighted average cost of capital assumption would have further increased the fair value of Tredegar’s interest in kaléo by approximately $4 million , and a 500 basis point increase in the weighted average cost of capital assumption would have decreased the fair value of the Company’s interest by approximately $4 million . Had the Company not elected to account for its investment under the fair value method, it would have been required to use the equity method of accounting. The condensed balance sheets for kaléo at December 31, 2015 and 2014 and related condensed statements of operations for the last three years ended December 31, 2015 , that were reported by kaléo, are provided below: December 31, December 31, (In Thousands) 2015 2014 2015 2014 Assets: Liabilities & Equity: Cash & short-term investments $ 91,844 $ 117,589 Restricted cash 8,182 14,498 Other current liabilities $ 10,261 $ 8,123 Other current assets 9,070 17,916 Other noncurrent liabilities 552 1,247 Property & equipment 8,453 10,824 Long-term debt, net (a) 142,696 146,629 Patents 2,811 2,702 Redeemable preferred stock — 22,946 Other long-term assets (a) 92 15 Equity (33,057 ) (15,401 ) Total assets $ 120,452 $ 163,544 Total liabilities & equity $ 120,452 $ 163,544 2015 2014 2013 Revenues & Expenses: Revenues $ 35,731 $ 21,156 $ 15,305 Cost of goods sold (14,147 ) (3,801 ) — Expenses and other, net (b) (63,042 ) (48,447 ) (18,631 ) Income tax (expense) benefit (481 ) 8,100 1,586 Net income (loss) $ (41,939 ) $ (22,992 ) $ (1,740 ) (a) Certain immaterial prior year balances have been reclassified to conform with current year presentation. (b) “Expenses and other, net” includes selling, general and administrative expense, research and development expense, interest expense and other income (expense), net. The audited financial statements and accompanying footnotes of kaléo as of December 31, 2015 and 2014 and for the years ended December 31, 2015 , 2014 and 2013 have been included as an exhibit to the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 filed with the Securities and Exchange Commission. On April 2, 2007, Tredegar invested $10.0 million in Harbinger Capital Partners Special Situations Fund, L.P. (the “Harbinger Fund”), a private investment fund that is subject to limitations on withdrawal. There is no secondary market for interests in the fund. The Company’s investment in the Harbinger Fund, which represents less than 1% of its total partnership capital, is accounted for under the cost method. Unrealized losses on the Company’s investment in the Harbinger Fund (included in “Other income (expense), net” in the consolidated statements of income) were $0.8 million ( $0.4 million after taxes) and $0.4 million ( $0.3 million after taxes) in 2014 and 2013 , respectively (none in 2015 ), as a result of a reduction in the estimated fair value of the investment that is not expected to be temporary. The December 31, 2015 and 2014 carrying value in the consolidated balance sheets (included in “Other assets and deferred charges”) was $1.7 million and $1.8 million , respectively. The carrying value at December 31, 2015 reflected Tredegar’s cost basis in its investment in Harbinger, net of total withdrawal proceeds received and unrealized losses. Withdrawal proceeds were $0.1 million in 2015 , $0.2 million in 2014 and $0.4 million in 2013 . The timing and amount of future installments of withdrawal proceeds was not known as of December 31, 2015 . There were no realized gains or losses associated with the investment in the Harbinger Fund in 2015 , 2014 and 2013 . Gains on the Company’s investment in the Harbinger Fund, if any, will be recognized when the amounts expected to be collected from withdrawal from the investment are known, which will likely be when cash in excess of the remaining carrying value is received. Losses will be recognized if management believes it is probable that future withdrawal proceeds will not exceed the remaining carrying value. Tredegar has investment property in Alleghany and Bath County, Virginia. The Company realized a gain (included in “Other income (expense), net” in the consolidated statements of income) of $1.2 million ( $0.8 million after taxes) on a sale of a portion of this investment property in 2014. The Company recorded an unrealized loss on its investment property in Alleghany and Bath County, Virginia of $1.0 million ( $0.6 million after taxes) in 2013 as a result of a reduction in the estimated fair value of the investment that is not expected to be temporary. The Company’s carrying value in this investment property (included in “Other assets and deferred charges” on the consolidated balance sheets) was $2.6 million at December 31, 2015 and $2.6 million at December 31, 2014 .

Segment Reporting [Abstract]
Business Segments	BUSINESS SEGMENTS Tredegar has historically reported two business segments: Film Products and Aluminum Extrusions. In 2015, the Company divided Film Products into two separate reportable segments: PE Films and Flexible Packaging Films. PE Films is comprised of the following operating segments: personal care materials, surface protection films, and engineered polymer solutions; and Flexible Packaging Films is comprised of the Company’s polyester films business, Terphane, which was acquired by Film Products in October 2011. As part of its transition to a new executive leadership team, the Company’s management has decided to discontinue its efforts to integrate Terphane with its other film products operations. In separating PE Films and Flexible Packaging Films, the Company’s management believes that it will be able to more effectively manage the distinct opportunities and challenges that each of these businesses face. Therefore, the Company's business segments are now PE Films, Flexible Packaging Films and Aluminum Extrusions. All historical results for PE Films and Flexible Packaging Films have been separately presented to conform with the new presentation of segments. Information by business segment and geographic area for the last three years is provided below. There were no accounting transactions between segments and no allocations to segments. Net sales (sales less freight) and operating profit from ongoing operations are the measures of sales and operating profit used by the chief operating decision maker (Tredegar’s President and Chief Executive Officer) for purposes of assessing performance. PE Films’ net sales to The Procter & Gamble Company (“P&G”) totaled $163.9 million in 2015 , $220.8 million in 2014 and $261.9 million in 2013 . These amounts include plastic film sold to others that convert the film into materials used with products manufactured by P&G.

These identifiable intangible assets, which have a cost basis of $4.2 million , were previously amortized over 2 years. A reconciliation of the beginning and ending balance of goodwill for each of the three years in the period ended December 31, 2015 is as follows: (In Thousands) PE Films Flexible Packaging Films Aluminum Extrusions (1) Total Net carrying value of goodwill at January 1, 2014 $ 104,161 $ 54,931 $ 13,696 $ 172,788 Increase (decrease) due to foreign currency translation (1 ) (3,100 ) — (3,101 ) Net carrying value of goodwill at December 31, 2014 104,160 51,831 13,696 169,687 Goodwill impairment charge — (44,465 ) — (44,465 ) Increase (decrease) due to foreign currency translation (17 ) (7,366 ) — (7,383 ) Net carrying value of goodwill at December 31, 2015 $ 104,143 $ — $ 13,696 $ 117,839 (1) Goodwill balance is net of accumulated impairment losses of $30.6 million . The Company recorded a goodwill impairment charge of $ 44.5 million ( $44.5 million after taxes) for goodwill associated with Flexible Packaging Films in 2015. This impairment charge represents the entire amount of goodwill associated with the Flexible Packaging Films segment. The operations of Flexible Packaging Films continue to be adversely impacted by competitive pressures that are primarily related to ongoing unfavorable economic conditions in its primary market of Brazil and excess global capacity in the industry. The Company believes that these conditions have shifted the competitive environment from a regional to a global landscape and have driven price convergence and lower product margins in Brazil. While recent favorable anti-dumping rulings have been issued against China, Egypt and India, authorities in Brazil have initiated new investigations of dumping against Peru and Bahrain. In light of market trends, increased economic uncertainty and continued dumping activity in Brazil, the Company reassessed its projections for the timing and extent of a market recovery with Flexible Packaging Films in 2015. The Company’s assessment of future prospects and timing of a recovery under these conditions indicate that its current enterprise value is less than $120 million (Flexible Packaging Films’ net assets excluding goodwill), the minimum value needed to have avoided a full write-off of its goodwill. The Company also assessed the fair value of Flexible Packaging Films’ other long-lived assets and determined that no additional impairments had occurred. Amortization expense for continuing operations over the next five years is expected to be as follows: Year Amount (In Thousands) 2016 $ 3,889 2017 3,850 2018 3,680 2019 3,280 2020 3,280

Financial Instruments

Financial Instruments	12 Months Ended

Summary of Derivative Instruments [Abstract]
Financial Instruments	FINANCIAL INSTRUMENTS Tredegar uses derivative financial instruments for the purpose of hedging margin exposure from fixed-price forward sales contracts in Aluminum Extrusions and currency exchange rate exposures that exist as part of ongoing business operations (primarily in PE Films). These derivative financial instruments are designated as and qualify as cash flow hedges and are recognized in the consolidated balance sheet at fair value. The fair value of derivative instruments recorded on the consolidated balance sheets are based upon Level 2 inputs. If individual derivative instruments with the same counterparty can be settled on a net basis, the Company records the corresponding derivative fair values as a net asset or net liability. In the normal course of business, Aluminum Extrusions enters into fixed-price forward sales contracts with certain customers for the future sale of fixed quantities of aluminum extrusions at scheduled intervals. In order to hedge margin exposure created from the fixing of future sales prices relative to volatile raw material (aluminum) costs, Aluminum Extrusions enters into a combination of forward purchase commitments and futures contracts to acquire or hedge aluminum, based on the scheduled purchases for the firm sales commitments. The fixed-price firm sales commitments and related hedging instruments generally have durations of not more than 12 months, and the notional amount of aluminum futures contracts that hedged future purchases of aluminum to meet fixed-price forward sales contract obligations was $16.6 million ( 18.9 million pounds of aluminum) at December 31, 2015 and $8.6 million ( 7.8 million pounds of aluminum) at December 31, 2014 . The table below summarizes the location and gross amounts of aluminum derivative contract fair values (Level 2) in the consolidated balance sheets as of December 31, 2015 and 2014 : December 31, 2015 December 31, 2014 (In Thousands) Balance Sheet Account Fair Value Balance Sheet Account Fair Value Derivatives Designated as Hedging Instruments Asset derivatives: Aluminum futures contracts Accrued expenses $ 44 Accrued expenses $ 82 Liability derivatives: Aluminum futures contracts Accrued expenses $ (1,797 ) Accrued expenses $ (318 ) Derivatives Not Designated as Hedging Instruments Asset derivatives: Aluminum futures contracts Accrued expenses $ — Accrued expenses $ 7 Liability derivatives: Aluminum futures contracts Accrued expenses $ — Accrued expenses $ (7 ) Net asset (liability) $ (1,753 ) $ (236 ) In the event that a counterparty to an aluminum fixed-price forward sales contract chooses not to take delivery of its aluminum extrusions, the customer is contractually obligated to compensate Aluminum Extrusions for any losses on the related aluminum futures and/or forward contracts through the date of cancellation. The offsetting asset and liability positions included in the table above are associated with the unwinding of aluminum futures contracts due to such cancellations. Tredegar used future fixed Euro-denominated contractual payments for equipment being purchased as part of its multi-year capacity expansion project at the film products manufacturing facility in Cabo de Santo Agostinho, Brazil. The Company used fixed rate Euro forward contracts with various settlement dates through February 2014 to hedge exchange rate exposure on these obligations. The Company did not have any fixed rate forward contracts with outstanding notional amounts as of December 31, 2015 and 2014 . Tredegar receives Euro-based royalty payments relating to its operations in Europe. From time to time Tredegar uses zero-cost collar currency options to hedge a portion of its exposure to changes in cash flows due to variability in U.S. Dollar and Euro exchange rates. There were no outstanding notional amounts on these collars at December 31, 2015 and 2014 as there were no derivatives outstanding related to the hedging of royalty payments with currency options. The counterparties to the Company’s forward purchase commitments are major aluminum brokers and suppliers, and the counterparties to aluminum futures contracts are major financial institutions. Fixed-price forward sales contracts are only made available to the best and most credit-worthy customers. The counterparties to Tredegar’s foreign currency futures and zero-cost collar contracts are major financial institutions. The pretax effect on net income (loss) and other comprehensive income (loss) of derivative instruments classified as cash flow hedges and described in the previous paragraphs for years ended December 31, 2015 , 2014 , and 2013 is summarized in the tables below: (In Thousands) Cash Flow Derivative Hedges Aluminum Futures Contracts Foreign Currency Forwards and Options Years Ended December 31, 2015 2014 2013 2015 2014 2013 Amount of pre-tax gain (loss) recognized in other comprehensive income $ (5,055 ) $ 542 $ (868 ) $ — $ (120 ) $ (77 ) Location of gain (loss) reclassified from accumulated other comprehensive income into net income (effective portion) Cost of sales Cost of sales Cost of sales Cost of Cost of Amount of pre-tax gain (loss) reclassified from accumulated other comprehensive income to net income (effective portion) $ (3,538 ) $ 631 $ (583 ) $ 62 $ 16 $ — Gains and losses on the ineffective portion of derivative instruments or derivative instruments that were not designated as hedging instruments were not significant in 2015 , 2014 and 2013 . For the years ended December 31, 2015 , 2014 and 2013 , unrealized net losses from hedges that were discontinued were not significant. As of December 31, 2015 , the Company expected $1.1 million of unrealized after-tax losses on derivative instruments reported in accumulated other comprehensive income to be reclassified to earnings within the next 12 months.

Debt Disclosure [Abstract]
Debt And Credit Agreements	DEBT AND CREDIT AGREEMENTS On April 23, 2012, Tredegar entered into a $350 million five -year, unsecured revolving credit facility (the “Credit Agreement”), with an option to increase that amount by an additional $75 million . The Credit Agreement replaced the previous $300 million four -year, unsecured revolving credit facility that was due to expire on June 21, 2014. In connection with the refinancing, the Company borrowed $102 million under the Credit Agreement, which was used, together with available cash on hand, to repay all indebtedness under the previous revolving credit facility. Borrowings under the Credit Agreement bear an interest rate of LIBOR plus a credit spread and commitment fees charged on the unused amount under the Credit Agreement at various indebtedness-to-adjusted-EBITDA levels as follows: Pricing Under Credit Revolving Agreement (Basis Points) Indebtedness-to-Adjusted EBITDA Ratio Credit Spread Over LIBOR Commitment Fee > 2.0x but <= 3.0x 200 35 > 1.0x but <=2.0x 175 30 <= 1.0x 150 25 At December 31, 2015 , the interest cost on debt borrowed under the Credit Agreement was priced at one-month LIBOR plus the applicable credit spread of 175 basis points. The most restrictive covenants in the Credit Agreement include: • Maximum indebtedness-to-adjusted EBITDA of 3.0 x; • Minimum adjusted EBIT-to-interest expense of 2.5 x; and • Maximum aggregate distributions to shareholders over the term of the Credit Agreement of $100 million plus, beginning with the fiscal quarter ended March 31, 2012, 50% of net income. At December 31, 2015 , based upon the most restrictive covenants within the Credit Agreement, available credit under the Credit Agreement was approximately $164 million . Total debt due and outstanding at December 31, 2015 is summarized below: Debt Due and Outstanding at December 31, 2015 (In Thousands) Year Due Credit Agreement Other Total Debt Due 2016 $ — $ — $ — 2017 104,000 — 104,000 2018 — — — 2019 — — — 2020 — — — Total $ 104,000 $ — $ 104,000 Tredegar believes that it was in compliance with all of its debt covenants as of December 31, 2015 . Noncompliance with any of the debt covenants may have a material adverse effect on financial condition or liquidity in the event such noncompliance cannot be cured or should the Company be unable to obtain a waiver from the lenders. Renegotiation of the covenant through an amendment to the Credit Agreement may effectively cure the noncompliance, but may have an effect on financial condition or liquidity depending upon how the covenant is renegotiated.

Shareholder Rights Agreement	SHAREHOLDER RIGHTS AGREEMENT Pursuant to the Second Amended and Restated Rights Agreement (the “Rights Agreement”), dated as of November 18, 2013, with Computershare Trust Company, N.A., as Rights Agent, one purchase right (a “Right”) was attached to each outstanding share of Tredegar’s common stock. Each Right entitled the registered holder to purchase from Tredegar one one-hundredth of a share of Tredegar’s Series A Participating Cumulative Preferred Stock at an exercise price of $150 , subject to adjustment (the “Purchase Price”). Unless otherwise noted in the Rights Agreement, the Rights would have become exercisable, if not earlier redeemed, only if a person or group (i) acquires beneficial ownership of 20% or more of the outstanding shares of the Company’s common stock or (ii) commences, or publicly discloses an intention to commence, a tender offer or exchange offer that would result in beneficial ownership by a person or group of 20% or more of the outstanding shares of the Company’s common stock. On February 19, 2014, Tredegar’s Board of Directors authorized the termination of the Rights Agreement and the redemption of all of the outstanding Rights, at a redemption price of $.01 per Right to be paid in cash to shareholders of record as of the close of business on March 3, 2014, with the payment date of such redemption price to be on March 7, 2014.

Compensation and Retirement Disclosure [Abstract]
Retirement Plans And Other Postretirement Benefits	RETIREMENT PLANS AND OTHER POSTRETIREMENT BENEFITS Tredegar sponsors noncontributory defined benefit (pension) plans covering certain current and former employees. The plans for salaried and hourly employees currently in effect are based on a formula using the participant’s years of service and compensation or using the participant’s years of service and a dollar amount. The plan is closed to new participants, and pay for active participants of the plan was frozen as of December 31, 2007. With the exception of plan participants at one of the Company’s U.S. manufacturing facilities, the plan no longer accrues benefits associated with crediting employees for service, thereby freezing all future benefits under the plan. In addition to providing pension benefits, the Company provides postretirement life insurance and health care benefits for certain groups of employees. Tredegar and retirees share in the cost of postretirement health care benefits, with employees hired on or before January 1, 1993, receiving a fixed subsidy to cover a portion of their health care premiums. The Company eliminated prescription drug coverage for Medicare-eligible retirees as of January 1, 2006. Consequently, Tredegar is not eligible for any federal subsidies. The following tables reconcile the changes in benefit obligations and plan assets in 2015 and 2014 , and reconcile the funded status to prepaid or accrued cost at December 31, 2015 and 2014 : Pension Benefits Other Post- Retirement Benefits (In Thousands) 2015 2014 2015 2014 Change in benefit obligation: Benefit obligation, beginning of year $ 325,426 $ 275,166 $ 8,372 $ 7,858 Service cost 530 869 44 43 Interest cost 13,217 13,397 325 387 Effect of actuarial (gains) losses related to the following: Discount rate change (14,687 ) 32,089 (356 ) 732 Retirement rate assumptions and mortality table adjustments (5,456 ) 17,331 32 (131 ) Retiree medical participation rate change — — — (390 ) Other (746 ) 490 (332 ) 218 Plan participant contributions — — 625 681 Benefits paid (14,432 ) (13,916 ) (965 ) (1,026 ) Benefit obligation, end of year $ 303,852 $ 325,426 $ 7,745 $ 8,372 Change in plan assets: Plan assets at fair value, beginning of year $ 229,017 $ 232,705 $ — $ — Actual return on plan assets (6,311 ) 7,466 — — Employer contributions 2,368 2,762 340 345 Plan participant contributions — — 625 681 Benefits paid (14,432 ) (13,916 ) (965 ) (1,026 ) Plan assets at fair value, end of year $ 210,642 $ 229,017 $ — $ — Funded status of the plans $ (93,210 ) $ (96,409 ) $ (7,745 ) $ (8,372 ) Amounts recognized in the consolidated balance sheets: Accrued expenses (current) $ 210 $ 130 $ 455 $ 456 Other noncurrent liabilities 93,000 96,279 7,290 7,916 Net amount recognized $ 93,210 $ 96,409 $ 7,745 $ 8,372 Assumptions used for financial reporting purposes to compute net benefit income or cost and benefit obligations for continuing operations, and the components of net periodic benefit income or cost for continuing operations, are as follows: Pension Benefits Other Post- Retirement Benefits (In Thousands, Except Percentages) 2015 2014 2013 2015 2014 2013 Weighted-average assumptions used to determine benefit obligations: Discount rate 4.55 % 4.17 % 4.99 % 4.49 % 4.11 % 4.88 % Expected long-term return on plan assets 7.00 % 7.50 % 7.75 % n/a n/a n/a Weighted-average assumptions used to determine net periodic benefit cost: Discount rate 4.17 % 4.99 % 4.21 % 4.11 % 4.88 % 4.10 % Expected long-term return on plan assets 7.50 % 7.75 % 7.75 % n/a n/a n/a Components of net periodic benefit cost: Service cost $ 530 $ 869 $ 3,754 $ 44 $ 43 $ 58 Interest cost 13,217 13,397 12,338 325 387 345 Expected return on plan assets (17,636 ) (18,301 ) (17,430 ) — — — Amortization of prior service costs and gains or losses 16,190 10,688 15,028 (194 ) (190 ) (210 ) Settlement/curtailment 45 81 28 — — — Net periodic benefit cost $ 12,346 $ 6,734 $ 13,718 $ 175 $ 240 $ 193 Net benefit income or cost is determined using assumptions at the beginning of each year. Funded status is determined using assumptions at the end of each year. The amount of the accumulated benefit obligation is the same as the projected benefit obligation. At December 31, 2015 , the effect of a 1% change in the health care cost trend rate assumptions would not impact the post-retirement obligation. Expected benefit payments for continuing operations over the next five years and in the aggregate for 2021-2025 are as follows: (In Thousands) Pension Benefits Other Post- Retirement Benefits 2016 $ 15,904 $ 455 2017 16,505 467 2018 16,969 478 2019 17,504 485 2020 17,997 489 2021—2025 94,105 2,468 Amounts recorded in 2015 , 2014 and 2013 in accumulated other comprehensive income, before related deferred income taxes, consist of: Pension Other Post-Retirement (In Thousands) 2015 2014 2013 2015 2014 2013 Prior service cost (benefit) $ 18 $ 87 $ 270 $ — $ — $ — Net actuarial (gain) loss 153,570 166,678 116,519 (1,616 ) (1,154 ) (1,773 ) Pension expense is expected to be $11.3 million in 2016 as the favorable impact of the increase in the discount rate, change to the mortality rate and the freezing of all future service benefits for certain plan participants are offset by the unfavorable decrease in the expected long-term return on plan assets. The amounts in accumulated other comprehensive income, before related deferred income taxes, that are expected to be recognized as components of net periodic benefit or cost during 2016 are as follows: (In Thousands) Pension Other Post- Retirement Prior service cost (benefit) $ 9 $ — Net actuarial (gain) loss 13,526 (190 ) The percentage composition of assets held by pension plans for continuing operations at December 31, 2015 , 2014 and 2013 are as follows: % Composition of Plan Assets at December 31, 2015 2014 2013 Pension plans related to continuing operations: Fixed income securities 12.8 % 14.5 % 14.0 % Large/mid-capitalization equity securities 13.8 13.7 13.8 Small-capitalization equity securities 4.0 4.3 4.8 International and emerging market equity securities 10.9 11.0 11.7 Total equity securities 28.7 29.0 30.3 Private equity and hedge funds 52.4 51.2 48.3 Other assets 6.1 5.3 7.4 Total for continuing operations 100.0 % 100.0 % 100.0 % Tredegar’s targeted allocation percentage for pension plan assets and the expected long-term rate of return on assets used to determine its benefit obligation at December 31, 2015 , are as follows: Target % Composition of Plan Assets * Expected Long-term Return % Pension plans related to continuing operations: Fixed income securities 25.0 % 4.4 % Large/mid-capitalization equity securities 14.0 8.8 Small-capitalization equity securities 4.0 10.0 International and emerging market equity securities 11.0 9.4 Total equity securities 29.0 9.4 Private equity and hedge funds 46.0 7.1 Total for continuing operations 100.0 % 7.0 % * Target percentages for the composition of plan assets represents a neutral position within the approved range of allocations for such assets. Expected long-term returns are estimated by asset class and generally are based on inflation-adjusted historical returns, volatilities, risk premiums and managed asset premiums. The portfolio of fixed income securities is structured with maturities that generally match estimated benefit payments over the next 1 - 2 years. The other assets category is primarily comprised of cash and contracts with insurance companies. The Company’s primary investment objective is to maximize total return with a strong emphasis on the preservation of capital, and it believes that over the long-term a diversified portfolio of fixed income securities, equity securities, hedge funds and private equity funds has a better risk-return profile than fixed income securities alone. The average remaining duration of benefit payments for the pension plans is about 11.7 years. The Company expects its required contributions to be approximately $6.1 million in 2016 . Estimates of the fair value of assets held by the Company’s pension plan are provided by unaffiliated third parties. At December 31, 2015, the Company adopted the updated accounting guidance associated with investments that utilized NAV as a practical expedient for measuring fair value. Investments in private equity and hedge funds and certain fixed income securities by the Company’s pension plan are measured at NAV. These assets are therefore excluded from the fair value hierarchy for each of the years presented. At December 31, 2015 and 2014 , the pension plan assets are categorized by level within the fair value measurement hierarchy as follows: (In Thousands) Total Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Balances at December 31, 2015: Large/mid-capitalization equity securities $ 29,027 $ 29,027 $ — $ — Small-capitalization equity securities 8,457 8,457 — — International and emerging market equity securities 23,054 10,126 12,928 — Fixed income securities 22,968 10,626 12,342 — Other assets 2,727 2,727 — — Total plan assets at fair value $ 86,233 $ 60,963 $ 25,270 $ — Private equity and hedge funds 110,340 Contracts with insurance companies 10,207 Fixed income securities 3,862 Total plan assets, December 31, 2015 $ 210,642 Balances at December 31, 2014: Large/mid-capitalization equity securities $ 31,401 $ 31,401 $ — $ — Small-capitalization equity securities 9,827 9,827 — — International and emerging market equity securities 25,224 11,471 13,753 — Fixed income securities 28,714 12,661 16,053 — Other assets 1,741 1,741 — — Total plan assets at fair value $ 96,907 $ 67,101 $ 29,806 $ — Private equity and hedge funds 117,276 Contracts with insurance companies 10,267 Fixed income securities 4,567 Total plan assets, December 31, 2014 $ 229,017 Tredegar also has a non-qualified supplemental pension plan covering certain employees. Effective December 31, 2005, further participation in this plan was terminated and benefit accruals for existing participants were frozen. The plan was designed to restore all or a part of the pension benefits that would have been payable to designated participants from the principal pension plans if it were not for limitations imposed by income tax regulations. The projected benefit obligation relating to this unfunded plan was $2.3 million at December 31, 2015 and $2.4 million at December 31, 2014 . Pension expense recognized for this plan was $0.1 million in 2015 , $0.1 million in 2014 and $0.1 million in 2013 . This information has been included in the preceding pension benefit tables. Approximately 79 employees at the Company’s film products manufacturing facility in Kerkrade, The Netherlands are covered by a collective bargaining agreement that includes participation in a multi-employer pension plan. Pension expense recognized for participation in this plan, which is equal to required contributions, was $0.4 million in 2015 , $0.5 million in 2014 and $0.5 million in 2013 . This information has been excluded from the preceding pension benefit tables.

Savings Plan [Abstract]
Savings Plan	SAVINGS PLAN Tredegar has a savings plan that allows eligible employees to voluntarily contribute a percentage of their compensation, up to Internal Revenue Service (“IRS”) limitations. The provisions of the savings plan provided the following benefits for salaried and certain hourly employees: • The Company makes matching contributions to the savings plan of $1 for every $1 of employee contribution. The matching contribution is currently on a maximum of 5% of base pay. • The savings plan includes immediate vesting of matching contributions when made and automatic enrollment at 3% of base pay unless the employee opts out or elects a different percentage. For the period from February 1, 2014 to December 31, 2014, the Company made matching contributions to the savings plan for salaried and non-union hourly employees of $0.50 for every $1 a participant contributed, with a matching contribution on a maximum of 5% of base pay during this period. The Company also has a non-qualified plan that restores matching benefits for employees suspended from the savings plan due to certain limitations imposed by income tax regulations. Charges recognized for these plans were $3.0 million in 2015 , $1.6 million in 2014 and $2.6 million in 2013 . The Company’s liability under the restoration plan was $1.0 million at December 31, 2015 (consisting of 71,818 phantom shares of common stock) and $1.7 million at December 31, 2014 (consisting of 74,190 phantom shares of common stock) and valued at the closing market price on those dates. The Tredegar Corporation Benefits Plan Trust (the “Trust”) purchased 7,200 shares of the Company’s common stock in 1998 for $0.2 million and 46,671 shares of its common stock in 1997 for $1.0 million , as a partial hedge against the phantom shares held in the restoration plan. There have been no shares purchased since 1998 except for re-invested dividends. The cost of the shares held by the Trust is shown as a reduction to shareholders’ equity in the consolidated balance sheets.

Also, there was a $0.5 million tax benefit related to the valuation allowance associated with capital losses in 2015 compared to a $4.9 million tax benefit in 2014. In 2014 there was a $2.2 million tax benefit recorded for changes in the underlying basis of certain foreign subsidiaries versus a $0.5 million tax benefit in 2015 for changes in the underlying basis of certain foreign subsidiaries. The reduction in income taxes from continuing operations in 2014 in comparison to prior years can be attributed to a pair of distinct tax adjustments. In recent years the Company has been evaluating various tax advantageous methods for executing its overall growth and international expansion strategies. The Company, having been authorized by its management in the fourth quarter of 2014 to proceed, implemented an international tax planning strategy that generated capital gains. These capital gains were offset against previously recorded capital losses on certain investments. Income taxes from continuing operations in 2014 therefore included the recognition of a tax benefit of $4.9 million related to a portion of its capital loss carryforwards that were previously offset by a valuation allowance associated with expected limitations on the utilization of historic capital losses carried over from the previous years. In addition, as previously discussed in Note 1, with the exception of Terphane, the Company accrues U.S. federal income taxes to the extent required under U.S. GAAP on unremitted earnings from foreign operations. As a result of changes in the underlying basis of certain foreign subsidiaries, income taxes from continuing operations in 2014 included an adjustment of $2.2 million in the fourth quarter, $1.7 million of which is a correction to prior years, to reverse previously accrued deferred tax liabilities accumulated over several years arising from changes in tax basis due to foreign currency translation adjustments and unremitted earnings. The corresponding prior period changes in the underlying basis of certain foreign subsidiaries primarily occurred before 2010, and the prior period components are not considered material to any period presented. The Brazilian federal statutory income tax rate is a composite of 34.0% ( 25.0% of income tax and 9.0% of social contribution on income). Terphane’s manufacturing facility in Brazil is the beneficiary of certain income tax incentives that allow for a reduction in the statutory Brazilian federal income tax rate levied on the operating profit of its products. These incentives produce a current tax rate of 15.25% for Terphane ( 6.25% of income tax and 9.0% social contribution on income). The current incentives will expire at the end of 2024. The benefit from the tax incentives was $0.1 million ( 0 cents per share), $0.1 million ( 0 cents per share) and $2.5 million ( 8 cent s per share) in 2015 , 2014 and 2013 , respectively.

The Company has estimated gross state and foreign tax credits and net operating loss carryforwards of $1.6 million and $3.0 million at December 31, 2015 and 2014 , respectively, which primarily expire at different points over the next 5 to 8 years. Valuation allowances of $1.5 million , $2.8 million and $1.7 million at at December 31, 2015 , 2014 and 2013 , respectively, are recorded against the tax benefit on state and foreign tax credits and net operating loss carryforwards generated by certain foreign and domestic subsidiaries that may not be recoverable in the carryforward period. The valuation allowance for excess capital losses from investments and other related items was $10.9 million , $11.4 million and $16.4 million at December 31, 2015 , 2014 and 2013 . The current year balance decreased due to changes in the relative amounts of capital gains and losses generated during the year. The amount of the deferred tax asset considered realizable, however, could be adjusted in the near term if estimates of the fair value of certain investments during the carryforward period change. Tredegar continues to evaluate opportunities to utilize capital loss carryforwards prior to their expiration at various dates in the future. As circumstances and events warrant, allowances will be reversed when it is more likely than not that future taxable income will exceed deductible amounts, thereby resulting in the realization of deferred tax assets. The valuation allowance for asset impairments in foreign jurisdictions where the Company believes it is more likely than not that the deferred tax asset will not be realized was $0.9 million at December 31, 2015 , $0.4 million at December 31, 2014 and $1.9 million at December 31, 2013 . A reconciliation of the Company’s unrecognized uncertain tax positions since January 1, 2013 , is shown below: Years Ended December 31, (In Thousands) 2015 2014 2013 Balance at beginning of period $ 3,255 $ 2,239 $ 910 Increase (decrease) due to tax positions taken in: Current period 518 619 643 Prior period 326 397 686 Increase (decrease) due to settlements with taxing authorities — — — Reductions due to lapse of statute of limitations (50 ) — — Balance at end of period $ 4,049 $ 3,255 $ 2,239 Additional information related to unrecognized uncertain tax positions since January 1, 2013 is summarized below: Years Ended December 31, (In Thousands) 2015 2014 2013 Gross unrecognized tax benefits on uncertain tax positions (reflected in current income tax and other noncurrent liability accounts in the balance sheet) $ 4,049 $ 3,255 $ 2,239 Deferred income tax assets related to unrecognized tax benefits on uncertain tax positions (reflected in deferred income tax accounts in the balance sheet) (858 ) (726 ) (540 ) Net unrecognized tax benefits on uncertain tax positions, which would impact the effective tax rate if recognized 3,191 2,529 1,699 Interest and penalties accrued on deductions taken relating to uncertain tax positions (approximately $90, $150 and $100 reflected in income tax expense in the income statement in 2015, 2014 and 2013, respectively, with the balance shown in current income tax and other noncurrent liability accounts in the balance sheet) 397 310 156 Related deferred income tax assets recognized on interest and penalties (148 ) (116 ) (60 ) Interest and penalties accrued on uncertain tax positions net of related deferred income tax benefits, which would impact the effective tax rate if recognized 249 194 96 Total net unrecognized tax benefits on uncertain tax positions reflected in the balance sheet, which would impact the effective tax rate if recognized $ 3,440 $ 2,723 $ 1,795 Tredegar, or one of its subsidiaries, files income tax returns in the U.S. federal jurisdiction, various states and jurisdictions outside the U.S. With few exceptions, Tredegar is no longer subject to U.S. federal, state or non-U.S. income tax examinations by tax authorities for years before 2012. The Company anticipates that it is reasonably possible that Federal and state income tax audits or statutes may settle or close within the next 12 months, which could result in the recognition of up to approximately $2.1 million of the balance of unrecognized tax positions, including any payments that may be made.

Results in 2015 include a net unrealized loss on the Company’s investment in kaléo (included in “Other income (expense), net” in the consolidated statements of income) of $20.5 million ( $15.7 million after taxes). See Note 4 for additional information on investments. On July 7, 2015, the Company announced its intention to consolidate its domestic production for PE Films by restructuring its manufacturing facility in Lake Zurich, Illinois. Efforts to transition domestic production from the Lake Zurich manufacturing facility will require various machinery upgrades and equipment transfers to its other manufacturing facilities. Given PE Films’ focus on maintaining product quality and customer satisfaction, the Company anticipates that these activities will be completed in the middle of 2017. Total pre-tax cash expenditures associated with restructuring the Lake Zurich manufacturing facility are expected to be approximately $15-16 million over this period, and once complete, annual pre-tax cash cost savings are expected to be approximately $5-6 million. The Company expects to recognize costs associated with the exit and disposal activities of approximately $4-5 million over the project period. Exit and disposal costs include severance charges and other employee-related expenses arising from the termination of employees of approximately $2-3 million and equipment transfers and other facility consolidation-related costs of approximately $2 million . During the same period of time, operating expenses will include the acceleration of approximately $3 million of non-cash depreciation expense for certain machinery and equipment at the Lake Zurich manufacturing facility. Total estimated cash expenditures of $15-16 million over the project period include the following: • Cash outlays associated with previously discussed exit and disposal expenses of approximately $4 million ; • Capital expenditures associated with equipment upgrades at other PE Films manufacturing facilities in the U.S. of approximately $10 million ; • Cash incentives of approximately $1 million in connection with meeting safety and quality standards while production ramps down at the Lake Zurich manufacturing facility; and • Additional operating expenses of approximately $1 million associated with customer product qualifications on upgraded and transferred production lines. Cash expenditures for restructuring costs in 2015 totaled $3.1 million , which included $2.5 million in capital expenditures. Losses associated with plant shutdowns, asset impairments, restructurings and other charges for continuing operations in 2014 (as shown in the segment operating profit table in Note 5) totaled $13.8 million ( $9.3 million after taxes), and unless otherwise noted below, are also included in “Asset impairments and costs associated with exit and disposal activities” in the consolidated statements of income. Results in 2014 included: • A second quarter charge of $10.0 million ( $6.8 million after taxes) associated with a one-time, lump sum license payment to the 3M Company after the Company settled all litigation issues associated with a patent infringement complaint (included in “Other income (expense), net” in the consolidated statements of income); • A fourth quarter charge of $0.5 million ( $0.3 million after taxes) in Flexible Packaging Films ( $0.3 million ) and PE Films ( $0.2 million ), a third quarter charge of $0.4 million ( $0.2 million after taxes) in Flexible Packaging Films ( $0.3 million ), PE Films ( $78,000 ) and Aluminum Extrusions ( $31,000 ), a second quarter charge of $0.6 million ( $0.4 million after taxes) in PE Films and a first quarter charge of $0.8 million ( $0.5 million after taxes) in PE Films for severance and other employee-related costs associated with restructurings; • A fourth quarter charge of $0.7 million ( $0.4 million after taxes), a third quarter charge of $ 75,000 ($ 46,000 after taxes) and a second quarter charge of $ 0.2 million ($ 0.1 million after taxes) related to expected future environmental costs at the aluminum extrusions manufacturing facility in Newnan, Georgia (included in “Cost of goods sold” in the consolidated statements of income); • A fourth quarter adjustment of previously accrued severance and other employee-related costs of $0.1 million ( $63,000 after taxes) and a third quarter charge of $37,000 ( $23,000 after taxes), a second quarter charge of $0.3 million ( $0.2 million after taxes) and a first quarter charge of $0.5 million ( $0.3 million after taxes) associated with the shutdown of the PE Films’ manufacturing facility in Red Springs, North Carolina, which includes net severance and other employee-related costs of $0.4 million and asset impairment and other shutdown-related charges of $0.3 million ; • A fourth quarter gain of $0.1 million ( $73,000 after taxes) related to the sale of a previously shutdown PE Films’ manufacturing facility in LaGrange, Georgia (included in “Other income (expense), net” in the consolidated statements of income); and • A fourth quarter charge of $11,000 ( $7,000 after taxes), a third quarter charge of $20,000 ( $12,000 after taxes) and a second quarter charge of $24,000 ( $15,000 after taxes) associated with the previously shutdown aluminum extrusions manufacturing facility in Kentland, Indiana. Results in 2014 include a net unrealized gain on the Company’s investment in kaléo (included in “Other income (expense), net” in the consolidated statements of income) of $2.0 million ( $1.0 million after taxes). An unrealized loss on the Company’s investment in the Harbinger Fund (included in “Other income (expense), net” in the consolidated statements of income and “Corporate expenses, net” in the statement of net sales and operating profit by segment) of $0.8 million ( $0.4 million after taxes) was recorded in 2014 as a result of a reduction in the fair value of the investment that is not expected to be temporary. The Company realized a gain on the sale of a portion of its investment property in Alleghany and Bath Counties, Virginia (included in “Other income (expense), net” in the consolidated statements of income) of $1.2 million ( $0.8 million after taxes) in 2014. See Note 4 for additional information on investments. Losses associated with plant shutdowns, asset impairments, restructurings and other charges for continuing operations in 2013 (as shown in the segment operating profit table in Note 5) totaled $3.4 million ( $2.2 million after taxes), and unless otherwise noted below, are also included in “Asset impairments and costs associated with exit and disposal activities” in the consolidated statements of income. Results in 2013 included: • A fourth quarter charge of $1.5 million ( $0.9 million after taxes), a third quarter charge of $0.1 million ( $62,000 after taxes) and a second quarter charge of $85,000 ( $53,000 after taxes) related to expected future environmental costs at the aluminum extrusions manufacturing facility in Newnan, Georgia (included in “Cost of goods sold” in the consolidated statements of income); • A third quarter charge of $45,000 ( $28,000 after taxes), a second quarter charge of $0.4 million ( $0.2 million after taxes) and a first quarter charge of $0.2 million ( $94,000 after taxes) associated with the previously shutdown aluminum extrusions manufacturing facility in Kentland, Indiana; • A fourth quarter charge of $0.3 million ( $0.2 million after taxes) and a third quarter charge of $0.2 million ( $83,000 after taxes) associated with the shutdown of the PE Films’ manufacturing facility in Red Springs, North Carolina, which includes severance and other employee related costs of $0.3 million and asset impairments of $0.2 million ; • A fourth quarter charge of $0.3 million ( $0.2 million after taxes) in Aluminum Extrusions and a first quarter charge of $0.1 million ( $67,000 after taxes) in PE Films associated with severance and other employee related costs in connection with restructurings; • A second quarter charge of $90,000 ( $54,000 after taxes) and a first quarter charge of $0.1 million ( $63,000 after taxes) for integration-related expenses and other non-recurring transactions (included in “Selling, general and administrative expenses” in the consolidated statements of income) associated with the acquisition of AACOA by Aluminum Extrusions; and • A second quarter loss of $91,000 ( $91,000 after taxes) related to the sale of previously impaired machinery and equipment at the film products manufacturing facility in Shanghai, China (included in “Other income (expense), net” in the consolidated statements of income). Results in 2013 include an unrealized gain on the Company’s investment in kaléo (included in “Other income (expense), net” in the consolidated statements of income) of $3.4 million ( $2.2 million after taxes). An unrealized loss on the Company’s investment in the Harbinger Fund (included in “Other income (expense), net” in the consolidated statements of income and “Corporate expenses, net” in the statement of net sales and operating profit by segment) of $0.4 million ( $0.3 million after taxes) was recorded in 2013 as a result of a reduction in the fair value of the investment that is not expected to be temporary. Tredegar also recorded an unrealized loss on its investment property in Alleghany and Bath County, Virginia of $1.0 million ( $0.6 million after taxes) in the second quarter of 2013 as a result of a reduction in the estimated fair value of the Company’s investment that was not expected to be temporary. See Note 4 for additional information on investments. PE Films closed its manufacturing facility in Red Springs, North Carolina in June 2014. The plant, which was a leased facility, was solely dedicated to producing babycare elastic laminate films for P&G, who has consolidated its North American suppliers for this product. The Red Springs manufacturing facility employed 66 people, and total charges incurred related to the shutdown, which primarily consisted of severance and other employee-related costs, were $0.7 million in 2014 and $0.5 million in 2013. Impairment charges were recognized to write down the machinery and equipment to the lower of their carrying value or estimated fair value. The estimated fair value of machinery and equipment that was evaluated for impairment was primarily based on estimates of the proceeds that the Company would receive if and/or when assets are sold. Estimates of the remaining fair value for the related machinery and equipment were based on both Level 2 and 3 inputs as defined under U.S. GAAP.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	CONTINGENCIES Tredegar is involved in various stages of investigation and remediation relating to environmental matters at certain current and former plant locations. Where the Company has determined the nature and scope of any required environmental remediation activity, estimates of cleanup costs have been obtained and accrued. As efforts continue to maintain compliance with applicable environmental laws and regulations, additional contingencies may be identified. If additional contingencies are identified, the Company’s practice is to determine the nature and scope of those contingencies, obtain and accrue estimates of the cost of remediation, and perform remediation. The Company does not believe that additional costs that could arise from those activities will have a material adverse effect on its financial position. However, those costs could have a material adverse effect on its financial condition, results of operations and cash flows at that time. The Company is involved in various other legal actions arising in the normal course of business. After taking into consideration the relevant information, the Company believes that it has sufficiently accrued for probable losses and that the actions will not have a material adverse effect on its financial position. However, the resolution of the actions in a future period could have a material adverse effect on quarterly or annual operating results at that time. From time to time, the Company enters into transactions with third parties in connection with the sale of assets or businesses in which it agrees to indemnify the buyers or third parties involved in the transaction, or in which the sellers or third parties involved in the transaction agree to indemnify Tredegar, for certain liabilities or risks related to the assets or business. Also, in the ordinary course of its business, the Company may enter into agreements with third parties for the sale of goods or services that may contain indemnification provisions. In the event that an indemnification claim is asserted, liability for indemnification would be subject to an assessment of the underlying facts and circumstances under the terms of the applicable agreement. Further, any indemnification payments may be limited or barred by a monetary cap, a time limitation, or a deductible or basket. For these reasons, Tredegar is unable to estimate the maximum amount of the potential future liability under the indemnity provisions of these agreements. The Company does, however, accrue for losses for any known contingent liability, including those that may arise from indemnification provisions, when future payment is probable and the amount is reasonably estimable. The Company discloses contingent liabilities if the probability of loss is reasonably possible and material. In 2011, Tredegar was notified by U.S. Customs and Border Protection (“U.S. Customs”) that certain film products exported by Terphane to the U.S. since November 6, 2008 could be subject to duties associated with an anti-dumping duty order on imported PET films from Brazil. The Company contested the applicability of these anti-dumping duties to the films exported by Terphane, and a request was filed with the U.S. Department of Commerce (“Commerce”) for clarification about whether the film products at issue are within the scope of the anti-dumping duty order. On January 8, 2013, Commerce issued a scope ruling confirming that the films are not subject to the order, provided that Terphane can establish to the satisfaction of U.S. Customs that the performance enhancing layer on those films is greater than 0.00001 inches thick. The films at issue are manufactured to specifications that exceed that threshold. On February 6, 2013, certain U.S. producers of PET film filed a summons with the U.S. Court of International Trade to appeal the scope ruling from Commerce. If U.S. Customs ultimately were to require the collection of anti-dumping duties because Commerce’s scope ruling was overturned on appeal, or otherwise, indemnifications for related liabilities are specifically provided for under the Terphane purchase agreement. In December 2014, the U.S. International Trade Commission voted to revoke the anti-dumping duty order on imported PET films from Brazil. The revocation, as a result of the vote by the International Trade Commission, was effective as of November 2013. On February 20, 2015, certain U.S. producers of Flexible Packaging Films filed a summons with the U.S. Court of International Trade to appeal the determination by the U.S. International Trade Commission.

Income taxes in the fourth quarter of 2014 included the recognition of a tax benefit for a portion of the Company’s capital loss carryforwards of $4.8 million . These capital loss carryforwards were previously offset by a valuation allowance associated with expected limitations on the utilization of these assumed capital losses. In addition, as previously discussed in Note 1, with the exception of Terphane, the Company accrues U.S. federal income taxes to the extent required under U.S. GAAP on unremitted earnings from foreign operations. As a result of changes in the underlying basis of certain foreign subsidiaries, income taxes from continuing operations in 2014 included an adjustment of $2.2 million in the fourth quarter, $1.7 million of which is a correction to prior years, to reverse previously accrued deferred tax liabilities accumulated over several years arising from changes in tax basis due to foreign currency translation adjustments and unremitted earnings. The corresponding prior period changes in the underlying basis of certain foreign subsidiaries primarily occurred before 2010, and the prior period components are not considered material to any period presented.

Summary Of Significant Accoun30

Summary Of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Basis Of Presentation	Basis of Presentation. The consolidated financial statements include the accounts and operations of Tredegar and all of its majority-owned subsidiaries. Intercompany accounts and transactions have been eliminated in consolidation. On February 12, 2008, Tredegar sold its aluminum extrusions business in Canada. All historical results for this business have been reflected as discontinued operations in these financial statements; however, cash flows for discontinued operations have not been separately disclosed in the consolidated statements of cash flows. See Note 3 regarding discontinued operations. The preparation of financial statements in conformity with United States (“U.S.”) generally accepted accounting principles (“U.S. GAAP”) requires Tredegar to make estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.
Foreign Currency Translation	Foreign Currency Translation. The financial statements of subsidiaries located outside the U.S., where the local currency is the functional currency, are translated into U.S. Dollars using exchange rates in effect at the period end for assets and liabilities and average exchange rates during each reporting period for results of operations. Adjustments resulting from the translation of these financial statements are reflected as a separate component of shareholders’ equity. There are no operating subsidiaries located outside the U.S. where the U.S. Dollar is the functional currency. Transaction and remeasurement gains or losses included in income were losses of $4.0 million , $1.5 million and $0.4 million in 2015 , 2014 and 2013 , respectively. These amounts do not include the effects between reporting periods that exchange rate changes have on income of the locations outside the U.S. that result from translation into U.S. Dollars.
Cash And Cash Equivalents	Cash and Cash Equivalents. Cash and cash equivalents consist of cash on hand in excess of daily operating requirements and highly liquid investments with original maturities of three months or less. At December 31, 2015 and 2014 , Tredegar had cash and cash equivalents of $44.2 million and $50.1 million , respectively, including funds held in locations outside the U.S. of $27.7 million and $40.5 million , respectively. The Company’s policy permits investment of excess cash in marketable securities that have the highest credit ratings and maturities of less than one year. The primary objectives of the policy are safety of principal and liquidity.
Accounts And Other Receivables	Accounts and Other Receivables. Accounts receivable are stated at the amount invoiced to customers less allowances for doubtful accounts and sales returns. Accounts receivable are non-interest bearing and arise from the sale of product to customers under typical industry trade terms. Notes receivable are not significant. Past due amounts are determined based on established terms and charged-off when deemed uncollectible. The allowance for doubtful accounts is determined based on an assessment of probable losses taking into account past due amounts, customer credit profile, historical experience and current economic conditions. Other receivables include value-added taxes related to certain foreign subsidiaries and other miscellaneous receivables due within one year.
Inventories	Inventories. Inventories are stated at the lower of cost or market, with cost determined on the last-in, first-out (“LIFO”) basis, the weighted average cost or the first-in, first-out basis. Cost elements included in work-in-process and finished goods inventories are raw materials, direct labor and manufacturing overhead.
Property, Plant And Equipment	Property, Plant and Equipment. Accounts include costs of assets constructed or purchased, related delivery and installation costs and interest incurred on significant capital projects during their construction periods. Expenditures for renewals and betterments also are capitalized, but expenditures for repairs and maintenance are expensed as incurred. The cost and accumulated depreciation applicable to assets retired or sold are removed from the respective accounts, and gains or losses thereon are included in income. Capital expenditures for property, plant and equipment include capitalized interest. Capitalized interest included in capital expenditures for property, plant and equipment was $0.4 million , $1.1 million and $0.9 million in 2015 , 2014 and 2013 , respectively. Depreciation is computed primarily by the straight-line method based on the estimated useful lives of the assets that, except for isolated exceptions, range from 5 to 40 years for buildings and land improvements and 2 to 20 years for machinery and equipment.
Investments In Private Entities With Less Than Or Equal To 50% Voting Ownership Interest	Investments in Private Entities with Less Than or Equal to 50% Voting Ownership Interest. The Company accounts for its investments in private entities where its voting ownership is less than or equal to 50% based on the facts and circumstances surrounding the investment. Investments are required to be accounted for under the consolidation method in situations where Tredegar is the primary beneficiary of a variable interest entity. The primary beneficiary is the party that has a controlling financial interest in a variable interest entity. The Company is deemed to have a controlling financial interest if it has (i) the power to direct activities of the variable interest entity that most significantly impact its economic performance and (ii) the obligation to absorb losses or the right to receive benefits from the variable interest entity that could potentially be significant to its operations. If the Company is not deemed to be the primary beneficiary in an investment in a variable interest entity then it selects either: (i) the fair value method or (ii) either (a) the cost method if it does not have significant influence over operating and financial policies of the investee or (b) the equity method if it does have significant influence. For those investments measured at fair value, U.S. GAAP requires disclosure of the level within the fair value hierarchy in which fair value measurements in their entirety fall, segregating fair value measurements using quoted prices in active markets for identical assets or liabilities (Level 1), significant other observable inputs (Level 2), and significant unobservable inputs (Level 3).
Goodwill And Other Intangibles	Goodwill and Other Intangibles. The excess of the purchase price over the fair value of identifiable net assets of acquired companies is allocated to goodwill. The Company assesses goodwill for impairment when events or circumstances indicate that the carrying value may not be recoverable or, at a minimum, on an annual basis (December 1 of each year). The Company recorded a goodwill impairment charge of $ 44.5 million ( $44.5 million after taxes) to write off the goodwill associated with Flexible Packaging Films in the third quarter of 2015. See Note 8 for additional details. The Company estimates the fair value of its reporting units using discounted cash flow analysis and comparative enterprise value-to-EBITDA (earnings before interest, taxes, depreciation and amortization) multiples. The remaining goodwill were tested for impairment at the annual testing date, with the estimated fair value of these reporting units substantially exceeding the carrying value of its net assets.
Impairment Of Long-Lived Assets	Impairment of Long-Lived Assets. The Company reviews long-lived assets for possible impairment when events indicate that an impairment may exist. For assets that are held and used in operations, if events indicate that an asset may be impaired, the Company estimates the future unlevered pre-tax cash flows expected to result from the use of the asset and its eventual disposition. Assets are grouped for this purpose at the lowest level for which there are identifiable and independent cash flows. If the sum of these undiscounted pre-tax cash flows is less than the carrying amount of the asset, an impairment loss is calculated. Measurement of the impairment loss is the amount by which the carrying amount exceeds the estimated fair value of the asset group. Assets that are held for sale are reported at the lower of their carrying amount or estimated fair value less cost to sell, with an impairment loss recognized for any write-down required.
Pension Costs And Postretirement Benefit Costs Other Than Pensions	Pension Costs and Postretirement Benefit Costs Other than Pensions. Pension costs and postretirement benefit costs other than pensions are accrued over the period employees provide service to Tredegar. Liabilities and expenses for pension plans and other postretirement benefits are determined using actuarial methodologies and incorporate significant assumptions, including the rate used to discount the future estimated liability, the long-term rate of return on plan assets, and several assumptions relating to the employee workforce. The Company recognizes the funded status of its pension and other postretirement plans in the accompanying consolidated balance sheets. Tredegar’s policy is to fund its pension plans at amounts not less than the minimum requirements of the Employee Retirement Income Security Act (“ERISA”) of 1974 and to fund postretirement benefits other than pensions when claims are incurred.
Revenue Recognition	Revenue Recognition. Revenue from the sale of products, which is shown net of estimated sales returns and allowances, is recognized when title has passed to the customer, the price of the product is fixed and determinable, and collectability is reasonably assured. Amounts billed to customers related to freight have been classified as sales in the accompanying consolidated statements of income. The cost of freight has been classified as a separate line in the accompanying consolidated statements of income. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction between Tredegar and its customers (such as value-added taxes) are accounted for on a net basis and therefore excluded from revenues.
Research & Development ("R&D") Costs	Research & Development (“R&D”) Costs. R&D costs are expensed as incurred and include primarily salaries, wages, employee benefits, equipment depreciation, facility costs and the cost of materials consumed relating to R&D efforts. R&D costs include a reasonable allocation of indirect costs.
Income Taxes	Income Taxes. Income taxes are recognized during the period in which transactions enter into the determination of income for financial reporting purposes, with deferred income taxes being provided at enacted statutory tax rates on the differences between the financial reporting and tax bases of assets and liabilities (see Note 17). Deferred U.S. federal income taxes have not been recorded for the undistributed earnings for Terphane Holdings, LLC (“Terphane”) because of the Company’s intent to permanently reinvest these earnings. Because of the accumulation of significant losses related to foreign currency translations at Terphane as of December 31, 2015 , there were no unrecorded deferred tax liabilities associated with the U.S. federal income taxes and foreign withholding taxes on undistributed earnings indefinitely invested outside the U.S. The Company accrues U.S. federal income taxes to the extent required under U.S. GAAP on unremitted earnings of all other foreign subsidiaries. A valuation allowance is recorded in the period when the Company determines that it is more likely than not that all or a portion of deferred tax assets may not be realized. The establishment and removal of a valuation allowance requires the Company to consider all positive and negative evidence and make a judgmental decision regarding the amount of valuation allowance required as of a reporting date. The benefit of an uncertain tax position is included in the accompanying financial statements when the Company determines that it is more likely than not that the position will be sustained, based on the technical merits of the position, if the taxing authority examines the position and the dispute is litigated. This determination is made on the basis of all the facts, circumstances and information available as of the reporting date.
Earnings Per Share	Earnings Per Share. Basic earnings per share is computed using the weighted average number of shares of common stock outstanding. Diluted earnings per share is computed using the weighted average common and potentially dilutive common equivalent shares outstanding, determined as follows: 2015 2014 2013 Weighted average shares outstanding used to compute basic earnings per share 32,578,116 32,302,108 32,171,751 Incremental shares attributable to stock options and restricted stock — 251,746 427,528 Shares used to compute diluted earnings per share 32,578,116 32,553,854 32,599,279 Incremental shares attributable to stock options and restricted stock are computed using the average market price during the related period. The Company had a net loss from continuing operations in 2015, so there is no dilutive impact for such shares. If the Company had reported net income from continuing operations in 2015, average out-of-the-money options to purchase shares that would have been excluded from the calculation of incremental shares attributable to stock options and restricted stock were 881,513 . The average out-of-the-money options to purchase shares that were excluded from the calculation of incremental shares attributable to stock options and restricted stock were 320,849 in 2014 and 31,167 in 2013 .
Stock-Based Employee Compensation Plans	Stock-Based Employee Compensation Plans. Compensation expense is recorded on all share-based awards based upon its calculated fair value over the requisite service period using the graded-vesting method. The fair value of stock option awards was estimated as of the grant date using the Black-Scholes options-pricing model. The fair value of restricted stock awards was estimated as of the grant date using the closing stock price on that date. The assumptions used in this model for valuing Tredegar stock options granted in 2014 and 2013 (no grants in 2015) are as follows: 2014 2013 Dividend yield 1.3 % 1.1 % Weighted average volatility percentage 43.5 % 48.3 % Weighted average risk-free interest rate 2.0 % 1.1 % Holding period (years): Officers 6.0 6.0 Management 5.0 5.0 Weighted average exercise price at date of grant (also weighted average market price at date of grant): Officers $ 22.49 $ 24.84 Management $ 22.33 $ 25.10 The dividend yield is the actual dividend yield on Tredegar’s common stock at the date of grant, which the Company believes is a reasonable estimate of the expected yield during the holding period. The expected volatility is based on the historical volatility of Tredegar’s common stock using a sequential period of historical data equal to the expected holding period of the option. The Company has no reason to believe that future volatility for this period is likely to differ from the past. The assumed risk-free interest rate is based on observed interest rates (zero coupon U.S. Treasury debt securities) appropriate for the expected holding period. The expected holding period and forfeiture assumptions are based on historical experience. Estimated forfeiture assumptions are reviewed through the vesting period. Adjustments are made if actual forfeitures differ from previous estimates. The cumulative effect of a change in estimated forfeitures is recognized in the period of the change.
Financial Instruments	Financial Instruments. Tredegar uses derivative financial instruments for the purpose of hedging aluminum price volatility and currency exchange rate exposures that exist as part of transactions associated with ongoing business operations. The Company’s derivative financial instruments are designated as and qualify as cash flow hedges and are recognized in the accompanying balance sheet at fair value. A change in the fair value of the derivative that is highly effective and that is designated and qualifies as a cash flow hedge is recorded in other comprehensive income. Gains and losses reported in other comprehensive income (loss) are reclassified to earnings in the periods in which earnings are affected by the variability of cash flows of the hedged transaction. Such gains and losses are reported on the same line as the underlying hedged item, and the cash flows related to financial instruments are classified in the consolidated statements of cash flows in a manner consistent with those of the transactions being hedged. Any hedge ineffectiveness (which represents the amount by which the changes in the fair value of the derivative exceed the variability in the cash flows of the forecasted transaction) is recorded in current period earnings. The amount of gains and losses recognized for hedge ineffectiveness were not material in 2015 , 2014 and 2013 . The Company’s policy requires that it formally document all relationships between hedging instruments and hedged items, as well as its risk management objective and strategy for undertaking various hedge transactions. The Company also formally assesses (both at the hedge’s inception and on an ongoing basis) whether the derivatives that are used in hedging transactions have been highly effective in offsetting changes in the fair value or cash flows of hedged items and whether those derivatives may be expected to remain highly effective in future periods. When it is determined that a derivative is not (or has ceased to be) highly effective as a hedge, the Company discontinues hedge accounting prospectively. As a policy, Tredegar does not engage in speculative or leveraged transactions, nor does it hold or issue financial instruments for trading purposes. Additional disclosure of the utilization of derivative hedging instruments is included in Note 9.
Comprehensive Income (Loss)	Comprehensive Income (Loss). Comprehensive income (loss) is defined as net income or loss as adjusted by other comprehensive income or loss items. Other comprehensive income (loss) includes changes in foreign currency translation adjustments, unrealized gains and losses on derivative financial instruments, prior service costs and net gains or losses from pension and other postretirement benefit plans arising during the period and amortization of these prior service costs and net gain or loss adjustments, all recorded net of deferred income taxes.
