Summary Of Significant Accounting Policies	12 Months Ended

Accounting Policies [Abstract]	'
Summary Of Significant Accounting Policies	'
	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Organization and Nature of Operations. Tredegar Corporation and subsidiaries (collectively “Tredegar,” “we,” “us” or “our”) are primarily engaged in the manufacture of plastic 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, we sold our aluminum extrusions business in Canada, and on November 20, 2012, we sold our mitigation banking business, Falling Springs, LLC (“Falling Springs”). All historical results for these businesses 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 us 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. 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. We have no 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 not material in 2013, 2012 and 2011. These amounts do not include the effects between reporting periods that exchange rate changes have on income of our 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, 2013 and 2012, Tredegar had cash and cash equivalents of $52.6 million and $48.8 million, respectively, including funds held in locations outside the U.S. of $38.6 million and $28.6 million, respectively.
	Our 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 our 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.
	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 were not material in 2013, 2012 and 2011.
	Depreciation is computed primarily by the straight-line method based on the estimated useful lives of the assets, which except for certain isolated exceptions, range from 10 to 30 years for buildings and land improvements and 2 to 17 years for machinery and equipment. The average depreciation period for machinery and equipment is approximately 10 years in Film Products and for the continuing operations of Aluminum Extrusions.
	Investments in Private Entities with Less Than or Equal to 50% Voting Ownership Interest. We account for our investments in private entities where our voting ownership is less than or equal to 50% based on the facts and circumstances surrounding the investment. We are required to account for investments under the consolidation method in situations where we are 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. We are deemed to have a controlling financial interest if we have (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 we are not deemed to be the primary beneficiary in an investment in a variable interest entity then we select either: (i) the fair value method or (ii) either (a) the cost method if we do not have significant influence over operating and financial policies of the investee or (b) the equity method if we do 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. We assess 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 1st of each year). Our significant reporting units in Film Products include Polyethylene and Polypropylene Films and PET Films. We have two reporting units in Aluminum Extrusions, Bonnell Aluminum and AACOA. Each of our reporting units has separately identifiable operating net assets (operating assets including goodwill and intangible assets net of operating liabilities).
	All goodwill in Aluminum Extrusions is associated with the AACOA reporting unit. Based on the severity of the economic downturn and its impact on the sales volumes of our aluminum extrusions business, the resulting operating loss in the first quarter of 2009, possible future losses and the uncertainty in the amount and timing of an economic recovery, a goodwill impairment charge of $30.6 million ($30.6 million after taxes), which represented the entire goodwill balance in the Bonnell Aluminum reporting unit, was recognized in 2009.
	We estimate the fair value of our reporting units using discounted cash flow analysis and comparative enterprise value-to-EBITDA (earnings before interest, taxes, depreciation and amortization) multiples. The goodwill of Polyethylene and Polypropylene Films reporting unit was tested for impairment at the annual testing date, with the estimated fair value of this reporting unit substantially exceeding the carrying value of its net assets. The goodwill of PET Films reporting unit was also tested for impairment at December 1, 2013, with the estimated fair value of this reporting unit exceeding the carrying value of its net assets by approximately 37%. The goodwill of AACOA is associated with the October 2012 acquisition of AACOA, Inc. (“AACOA”), and estimated fair value of this reporting unit exceeded the carrying value of its net assets by approximately 22% at December 1, 2013.
	Impairment of Long-Lived Assets. We review 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, we estimate 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. We recognize the funded status of our pension and other postretirement plans in the accompanying consolidated balance sheets. Our policy is to fund our 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 Ltda. (a subsidiary of Film Products) because of our intent to permanently reinvest these earnings. We have not recorded a deferred liability of approximately $7.1 million related to the U.S. federal income taxes and foreign withholding taxes on approximately $36.0 million of undistributed earnings indefinitely invested outside the U.S. at December 31, 2013. We accrue U.S. federal income taxes on unremitted earnings of all other foreign subsidiaries. The benefit of an uncertain tax position is included in the accompanying financial statements when we determine 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:
		2013			2012			2011
	Weighted average shares outstanding used to compute basic earnings per share	32,171,751			32,032,343			31,931,962
	Incremental shares attributable to stock options and restricted stock	427,528			160,233			281,212
	Shares used to compute diluted earnings per share	32,599,279			32,192,576			32,213,174
	Incremental shares attributable to stock options and restricted stock are computed using the average market price during the related period. During 2013, 2012 and 2011, 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 was 31,167, 632,050 and 293,704, respectively.
	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 our closing stock price on that date.
	The assumptions used in this model for valuing Tredegar stock options granted in 2013, 2012 and 2011 are as follows:
		2013				2012			2011
	Dividend yield	1.1		%		0.9		%	0.9		%
	Weighted average volatility percentage	48.3		%		48.7		%	46.4		%
	Weighted average risk-free interest rate	1.1		%		1		%	2.5		%
	Holding period (years):
	Officers	6				6			6
	Management	5				5			5
	Weighted average exercise price at date of grant (also weighted average market price at date of grant):
	Officers	$	24.84			$	19.3		$	19.84
	Management	25.1				19.4			19.73
	The dividend yield is the dividend yield on our common stock at the date of grant, which we believe is a reasonable estimate of the expected yield during the holding period. We calculate expected volatility based on the historical volatility of our common stock using a sequential period of historical data equal to the expected holding period of the option. We have 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 2013, 2012 and 2011, and related estimated fair value at the date of grant, are as follows:
		2013				2012			2011
	Stock options granted (number of shares):
	Officers	94,400				99,600			140,500
	Management	90,300				82,500			95,300
	Total	184,700				182,100			235,800
	Estimated weighted average fair value of options per share at date of grant:
	Officers	$	10.37			$	8.07		$	8.55
	Management	9.65				7.81			8.03
	Total estimated fair value of stock options granted (in thousands)	$	1,850			$	1,449		$	1,966
	Additional disclosure of Tredegar stock options is included in Note 13.
	Financial Instruments. We use derivative financial instruments for the purpose of hedging aluminum price volatility and currency exchange rate exposures that exist as part of transactions associated with our ongoing business operations. Our 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 as 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 2013, 2012 and 2011.
	Our policy requires that we formally document all relationships between hedging instruments and hedged items, as well as our risk management objective and strategy for undertaking various hedge transactions. We also formally assess (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, we discontinue hedge accounting prospectively.
	As a policy, we do not engage in speculative or leveraged transactions, nor do we hold or issue financial instruments for trading purposes. Additional disclosure of our utilization of derivative hedging instruments is included in Note 9.
	Comprehensive Income (Loss). Comprehensive income (loss) is defined as net income or loss and other comprehensive income or loss. 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 gains or losses 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, 2013:
	(In Thousands)	Foreign currency translation adjustment				Gain (loss) on derivative financial instruments			Pension and other post-retirement benefit adjustments			Total
	Beginning balance, January 1, 2013	$	131			$	993		$	(103,471	)	$	(102,347	)
	Other comprehensive income (loss) before reclassifications	(19,336		)		134			22,203			3,001
Amounts reclassified from accumulated other comprehensive income (loss)	—				(362		)	9,420			9,058
Net other comprehensive income (loss) - current period	(19,336		)		(228		)	31,623			12,059
Ending balance, December 31, 2013	$	(19,205	)		$	765		$	(71,848	)	$	(90,288	)
Reclassifications of balances out of accumulated other comprehensive income (loss) into net income during 2013 are summarized as follows:
(In Thousands)	Amount reclassified from other comprehensive income				Location of gain (loss) reclassified from accumulated other comprehensive income to net income
Gain (loss) on derivative financial instruments:
Aluminum future contracts, before taxes	$	(583	)		Cost of sales
Foreign currency forward contracts, before taxes	—
Total, before taxes	(583		)
Income tax expense (benefit)	(221		)		Income taxes
Total, net of tax	$	(362	)
Amortization of pension and other post-retirement benefits:
Actuarial gain (loss) and prior service costs, before taxes	$	(14,818	)		(a)
Income tax expense (benefit)	(5,398		)		Income taxes
Total, net of tax	$	(9,420	)
(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 February 2013, the Financial Accounting Standards Board (“FASB”) issued updated guidance to address the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount under the arrangement is fixed at the reporting date. Under the new guidance, an entity would measure its obligation from a joint and several liability arrangement as the sum of the amount the entity agreed with its co-obligors that it will pay, and any additional amount the entity expects to pay on behalf of its co-obligors. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2013. Early application is permitted, and we do not expect the guidance to impact us.
In March 2013, the FASB issued updated guidance related to foreign currency matters. The updated guidance attempts to resolve the diversity in practice about the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity. In addition, the amended guidance attempts to resolve the diversity in practice for the treatment of business combinations achieved in stages involving a foreign entity. The guidance is effective for the first annual period beginning after December 15, 2013, and we do expect the guidance to impact us.
In July 2013, the FASB issued new guidance regarding the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists.  The new guidance requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, unless certain exceptions are met.  The amendments are effective prospectively for fiscal and interim periods beginning after December 15, 2013. We are still assessing the applicability of this guidance in future periods.

Acquisitions	'
	ACQUISITIONS
	On October 1, 2012, The William L. Bonnell Company, Inc. acquired 100% ownership of AACOA. AACOA operates production facilities in Elkhart, Indiana and Niles, Michigan. Its primary markets include consumer durables, machinery and equipment and transportation. The acquisition will add fabrication capabilities to Aluminum Extrusions’ current 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 our existing $350 million revolving credit facility. Based upon management’s valuation of the fair value of tangible and intangible assets acquired (net of cash acquired) and liabilities assumed, the preliminary estimated purchase price allocation is as follows:
	(In Thousands)
	Accounts receivable	$	12,477
	Inventories	4,708
	Property, plant & equipment	15,116
	Identifiable intangible assets:
	Customer relationships	4,800
	Trade names	4,800
	Proprietary technology	3,400
	Noncompete agreements	1,600
	Other assets (current & noncurrent)	42
	Trade payables & accrued expenses	(6,574		)
	Total identifiable net assets	40,369
	Purchase price, net of cash received	54,065
	Goodwill	$	13,696
	The goodwill and other intangible asset balances associated with this acquisition will be deductible for tax purposes. Intangible assets acquired in the purchase of AACOA are being amortized over the following periods:
	Identifiable Intangible Asset	Useful Life (Yrs)
	Customer relationships	10
	Proprietary technology	10-Jun
	Trade names	Indefinite
	Noncompete agreements	2
	On October 14, 2011, TAC Holdings, LLC (the “Buyer”) and Tredegar Film Products Corporation, which are indirect and direct, respectively, wholly-owned subsidiaries of Tredegar, entered into a Membership Interest Purchase Agreement (the “Purchase Agreement”) with Gaucho Holdings, B.V. (the “Seller”) an indirect, wholly-owned subsidiary of Vision Capital Partners VII LP (“Vision Capital”). On October 24, under the terms of the Purchase Agreement, the Buyer acquired from the Seller 100% of the outstanding equity interests of Terphane Holdings, LLC (“Terphane”).
	Terphane operates manufacturing facilities in Cabo de Santo Agostinho, Brazil and Bloomfield, New York. It is a producer of thin polyester films in Latin America with a growing presence in strategic niches in the U.S. Polyester films have specialized properties, such as heat resistance and barrier protection, that make them uniquely suited for the flexible packaging market. We expect that the acquisition of Terphane will allow us to extend our product offerings into adjacent specialty films markets and to expand in Latin America.
	All post-closing adjustments related to the purchase price for Terphane were resolved in 2012. Adjustments to the purchase price were made retrospectively as if the accounting had been completed on the acquisition date. Upon completing these post-closing adjustments, which were primarily related to working capital transferred, the total purchase price (net of cash acquired) was $182.7 million. The purchase price was funded using available cash (net of cash received) of approximately $57.7 million and financing of $125 million secured from Tredegar’s former revolving credit facility. Based upon management’s valuation of the fair value of tangible and intangible assets acquired (net of cash acquired) and liabilities assumed, the final estimated purchase price allocation was as follows:
	(In Thousands)
	Accounts receivable	$	14,321
	Inventories	23,437
	Property, plant & equipment	86,963
	Identifiable intangible assets:
	Customer relationships	32,600
	Proprietary technology	14,700
	Trade names	9,400
	Noncompete agreements	2,300
	Other assets (current & noncurrent)	3,680
	Trade payables	(17,471		)
	Other liabilities (current & noncurrent)	(12,216		)
	Deferred taxes	(38,167		)
	Total identifiable net assets	119,547
	Purchase price, net of cash received	182,761
	Goodwill	$	63,214
	None of the goodwill or other intangible assets will be deductible for tax purposes. Intangible assets acquired in the purchase of Terphane are being amortized over the following periods:
	Identifiable Intangible Asset	Useful Life (Yrs)
	Customer relationships	12
	Proprietary technology	10
	Trade names	Indefinite
	Noncompete agreements	2
	The financial position and results of operations for AACOA and Terphane have been consolidated with Tredegar subsequent to October 1, 2012. For the year ended December 31, 2012, the consolidated results of operations included sales of $19.9 million and net income from continuing operations of $1.0 million related to AACOA. The financial position and results of operations for Terphane have been consolidated with Tredegar subsequent to October 24, 2011. For the year ended December 31, 2011, the consolidated results of operations included sales of $29.2 million and net income from continuing operations of $2.0 million related to Terphane.
	The following unaudited supplemental pro forma data presents our consolidated revenues and earnings as if the acquisitions of Terphane and AACOA had been consummated on January 1, 2011. The pro forma results are not necessarily indicative of our consolidated revenues and earnings if the acquisition and related borrowing had been consummated on January 1, 2011. Supplemental unaudited pro forma results for the years ended December 31, 2012 and 2011 are as follows:
	(In Thousands, Except Per Share Data)		2012		2011
	Sales		$	946,594	$	1,009,601
	Income from continuing operations		44,816		43,407
	Earnings per share from continuing operations:
	Basic		$	1.4	$	1.36
	Diluted		1.39		1.35
	The above supplemental unaudited pro forma amounts reflect the application of the following adjustments in order to present the consolidated results as if the acquisitions and related borrowings had occurred on January 1, 2011:
	•	Adjustment for additional depreciation and amortization expense associated with the adjustments to property, plant and equipment, and intangible assets associated with purchase accounting;
	•	Additional interest expense and financing fees associated with borrowing arrangements used to fund the acquisitions of Terphane and AACOA and the elimination of historical interest expense associated with historical borrowings of Terphane and AACOA that were not assumed by Tredegar;
	•	Adjustments to eliminate transactions-related expenses associated with the October 2011 acquisition of Terphane and the October 2012 acquisition of AACOA;
	•	Adjustments related to the elimination of foreign currency remeasurement gains associated with long-term borrowings of Terphane that were not assumed by Tredegar;
	•	Adjustments for the estimated net income tax benefit associated with the previously described adjustments; and
	•	Adjustments to income tax expense for AACOA as it had previously elected to be treated as an S-Corp for federal income tax purposes.

	DISCONTINUED OPERATIONS
	On November 20, 2012, Tredegar Real Estate Holdings, Inc., a wholly-owned subsidiary, sold its membership interests in Falling Springs to Arc Ventures, LC for $16.6 million. Arc Ventures, LC is a Virginia limited liability company affiliated with John D. Gottwald, a member of our Board of Directors. The purchase price was comprised of $12.8 million of cash and 209,576 shares of common stock of Tredegar owned by Arc Ventures, LC. The corresponding loss on sale of $3.1 million, which includes transaction-related expenses of $0.5 million, and the results of operations related to Falling Springs have been classified as discontinued operations for all periods presented. For the years ended December 31, 2012 and 2011, sales of $3.2 million and $3.2 million, respectively, have been reclassified to discontinued operations, and net income of $0.5 million and $0.7 million have been reclassified to discontinued operations in 2012 and 2011, respectively. Falling Springs was formerly a component of the Other segment.
	On February 12, 2008, we sold our aluminum extrusions business in Canada for approximately $25.0 million to an affiliate of H.I.G. Capital. In 2013, 2012 and 2011, accruals of $14.0 million ($14.0 million net of tax), $13.4 million ($13.4 million net of tax) and $4.4 million ($4.4 million net of tax) were made for indemnifications under the purchase agreement related to environmental matters.
	The historical results for these businesses, 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, we made an aggregate investment of $7.5 million in kaleo, Inc. (“kaléo”), a privately held specialty pharmaceutical company formerly known as Intelliject, Inc. The mission of kaléo is to set a new standard in life-saving personal medical products designed to enable superior treatment outcomes, improved cost effectiveness and intuitive patient administration. Our ownership interest on a fully diluted basis is approximately 20%, and the investment is accounted for under the fair value method. At the time of our initial investment, we elected the fair value option over the equity method of accounting since our investment objectives were similar to those of venture capitalists, which typically do not have controlling financial interests. We recognized a net unrealized gain of $3.4 million ($2.2 million after taxes) in 2013 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 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.
	We recognized an unrealized gain of $16.1 million ($10.2 million after taxes) in 2012 attributed to various factors, most notably:
	•	a favorable adjustment to the timing and amount of anticipated cash flows derived from updated marketing research;
	•	the passage of time as anticipated cash flows associated with achieving product development commercialization milestones are discounted at 55% for their high degree of risk; and
	•	a reduction in the weighted average cost of capital used to discount cash flows in our valuation in the first quarter to reflect the completion of certain process testing and a reassessment of the risk associated with the timing for obtaining final marketing approval from the U.S. Food and Drug Administration (“FDA”) for the company’s first product.
	In 2011, we recognized an unrealized gain of $1.6 million ($1.0 million after taxes) attributed to the appreciation of our interest upon changes in the market dynamics and pricing associated with an upcoming product introduction and the addition of projects to the 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.
	At December 31, 2013 and 2012, the estimated fair value of our investment (included in “Other assets and deferred charges” in the consolidated balance sheets) was $37.1 million and $33.7 million, respectively. Subsequent to our most recent investment (December 15, 2008), and until the next round of financing, we believe fair value estimates are based upon Level 3 inputs since there is no secondary market for our 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 the high degree of risk. As a result, any future changes in the estimated fair value of our ownership interest will likely be attributed to a new round of financing, a merger or initial public offering or adjustments to the timing or magnitude of cash flows associated with development and commercialization milestones. If kaléo does not meet its development and commercialization milestones and there are indications that the amount or timing of its projected cash flows or related risks are unfavorable versus our most recent valuation, or a new round of financing or other significant financial transaction indicates a lower enterprise value, then our estimate of the fair value of our ownership interest in the company is likely to decline. Adjustments to the estimated fair value of our investment will be made in the period upon which such changes can be quantified.
	The fair market valuation of our 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 our interest in kaléo was 55% at December 31, 2013 and 2012. At December 31, 2013, the effect of a 500 basis point decrease in the weighted average cost of capital assumption would have further increased the fair value of our interest in kaléo by approximately $5 million, and a 500 basis point increase in the weighted average cost of capital assumption would have decreased the fair value of our interest by approximately $5 million.
	Had we not elected to account for our investment under the fair value method, we would have been required to use the equity method of accounting. The condensed balance sheets for kaléo at December 31, 2013 and 2012 and related condensed statements of operations for the last three years ended December 31, 2013, that were reported to us by kaléo, are provided below:

	On April 2, 2007, we invested $10.0 million in Harbinger Capital Partners Special Situations Fund, L.P. (“Harbinger”), a private investment fund that is subject to limitations on withdrawal. There is no secondary market for interests in the fund. Our investment in Harbinger, which represents less than 2% of its total partnership capital, is accounted for under the cost method. We recorded unrealized losses of $0.4 million ($0.3 million after taxes), $1.1 million ($0.7 million after taxes) and $0.6 million ($0.4 million after taxes) on our investment in Harbinger in 2013, 2012 and 2011, respectively, as a result of a reduction in the estimated fair value of our investment that is not expected to be temporary. The December 31, 2013 and 2012 carrying value in the consolidated balance sheets (included in “Other assets and deferred charges”) was $2.8 million and $3.6 million, respectively. The carrying value at December 31, 2013 reflected Tredegar’s cost basis in its investment in Harbinger, net of total withdrawal proceeds received and unrealized losses. Withdrawal proceeds were $0.4 million in 2013, $0.5 million in 2012 and $0.6 million in 2011. The timing and amount of future installments of withdrawal proceeds was not known as of December 31, 2013. There were no realized gains or losses associated with our investment in Harbinger in 2013, 2012 and 2011. Gains on our investment in Harbinger, if any, will be recognized when the amounts expected to be collected from our withdrawal from the investment are known, which will likely be when cash in excess of our 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.
	We have investment property in Alleghany and Bath County, Virginia. We also recorded an unrealized loss on our 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 our investment that is not expected to be temporary. Our carrying value in this investment property (included in “Other assets and deferred charges” on the consolidated balance sheets) was $5.9 million at December 31, 2013 and $6.9 million at December 31, 2012.

Segment Reporting [Abstract]	'
Business Segments	'
	BUSINESS SEGMENTS
	Our primary business segments are Film Products and Aluminum Extrusions. Beginning in February 2010, we started reporting an additional segment, Other, comprised of the start-up operations of Bright View and Falling Springs. Effective January 1, 2012, the operations and results of Bright View were incorporated into Film Products to leverage research and development efforts and accelerate new product development. Prior year balances for Bright View have been reclassified to Film Products to conform with the current year presentation. As discussed in Note 3, Falling Springs was divested in November 2012. All historical results for this business have been reflected as discontinued operations. With the sale of Falling Springs, there is no longer an Other segment to report.
	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 for purposes of assessing performance. Film Products’ net sales to The Procter & Gamble Company (“P&G”) totaled $261.9 million in 2013, $264.0 million in 2012 and $280.3 million in 2011. These amounts include plastic film sold to others that convert the film into materials used with products manufactured by P&G.

	(d)	Information on exports and foreign operations are provided on the next page. Cash and cash equivalents includes funds held in locations outside the U.S. of $38.6 million and $28.6 million at December 31, 2013 and 2012, respectively. Export sales relate almost entirely to Film Products. Operations outside the U.S. in The Netherlands, Hungary, China, Italy (sold in 2011), Brazil and India also relate to Film Products. Sales from our locations in The Netherlands, Hungary and Italy are primarily to customers located in Europe. Sales from our locations in China (Guangzhou and Shanghai) are primarily to customers located in China, but also include other customers in Asia. Sales activity at the new film products manufacturing facility in India was not significant in 2011.

Summary of Derivative Instruments [Abstract]	'
Financial Instruments	'
	FINANCIAL INSTRUMENTS
	We use 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 Film Products). Our 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, we record the corresponding derivative fair values as a net asset or net liability.
	In the normal course of business, we enter 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 our margin exposure created from the fixing of future sales prices relative to volatile raw material (aluminum) costs, we enter 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. 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 us for any losses on the related aluminum futures and/or forward purchase contracts through the date of cancellation. 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 $8.0 million (8.4 million pounds of aluminum) at December 31, 2013 and $6.2 million (6.7 million pounds of aluminum) at December 31, 2012.
	The table below summarizes the location and gross amounts of aluminum derivative contract fair values in the consolidated balance sheets as of December 31, 2013 and 2012:
		31-Dec-13						31-Dec-12
	(In Thousands)	Balance Sheet		Fair				Balance Sheet	Fair

	Liability derivatives:	Accrued expenses		$	178			Prepaid expenses	$	88
	Aluminum futures contracts							and other
	Net asset (liability)			$	(147	)			$	138
	We have future fixed Euro-denominated contractual payments for equipment being purchased as part of our multi-year capacity expansion project at our film products manufacturing facility in Cabo de Santo Agostinho, Brazil. We are using fixed rate Euro forward contracts with various settlement dates through February 2014 to hedge exchange rate exposure on these obligations. We had fixed rate forward contracts with outstanding notional amounts of €2.1 million as of December 31, 2013 and €9.9 million as of December 31, 2012.
	The table below summarizes the location and gross amounts of foreign currency forward contract fair values in the consolidated balance sheets as of December 31, 2013 and 2012:
		31-Dec-13						31-Dec-12
	(In Thousands)	Balance Sheet		Fair				Balance Sheet	Fair

	Asset derivatives:	Prepaid expenses		$	47			Prepaid expenses	$	948
	Foreign currency forward contracts	and other						and other
	Net asset (liability)			$	47				$	948
	We receive Euro-based royalty payments relating to our operations in Europe. From time to time we use zero-cost collar currency options to hedge a portion of our 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, 2013 and 2012 as there were no derivatives outstanding related to the hedging of royalty payments with currency options.
	The counterparties to our forward purchase commitments are major aluminum brokers and suppliers, and the counterparties to our aluminum futures contracts are major financial institutions. Fixed-price forward sales contracts are only made available to our best and most credit-worthy customers. The counterparties to our 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, 2013, 2012, and 2011 is summarized in the tables below:

	Gains and losses on the ineffective portion of derivative instruments or derivative instruments that were not designated as hedging instruments were not significant in 2013, 2012 and 2011. For the years ended December 31, 2013, 2012 and 2011, unrealized net losses from hedges that were discontinued were not significant. As of December 31, 2013, we expect $0.1 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 And Credit Agreements	'
	DEBT AND CREDIT AGREEMENTS
	On April 23, 2012, we 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 our previous $300 million four-year, unsecured revolving credit facility that was due to expire on June 21, 2014. In connection with the refinancing, we borrowed $102 million under the Credit Agreement, which was used, together with available cash on hand, to repay all indebtedness under our 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	Commitment
			Over LIBOR	Fee
	> 2.0x but <=.0x		200	35
	> 1.0x but <=0x		175	30
	<=.0x		150	25
	At December 31, 2013, 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 3.0x;
	•	Minimum adjusted EBIT-to-interest expense of 2.5x;
	•	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; and
	•	Minimum shareholders’ equity at any point during the term of the Credit Agreement of at least $320 million increased on a cumulative basis at the end of each fiscal quarter, beginning with the fiscal quarter ended March 31, 2012, by an amount equal to 50% of net income (to the extent positive).
	At December 31, 2013, based upon the most restrictive covenants within the Credit Agreement, available credit under the Credit Agreement was approximately $165 million. Total debt due and outstanding at December 31, 2013 is summarized below:
	Debt Due and Outstanding at December 31, 2013

	We believe we were in compliance with all of our debt covenants as of December 31, 2013. 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 we 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”) is attached to each outstanding share of our Common Stock.  All Rights previously issued under the original Rights Agreement, dated as of June 30, 1999, and the Amended and Restated Rights Agreement, dated as of June 30, 2009, that were appurtenant to shares of Common Stock outstanding at the effective time of the Rights Agreement remain outstanding.
	Each Right entitles the registered holder to purchase from Tredegar one one-hundredth of a share of our Series A Participating Cumulative Preferred Stock (the “Preferred Stock”) at an exercise price of $150, subject to adjustment (the "Purchase Price"). The Rights will 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 our 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 our Common Stock (in each case thereby becoming an “Acquiring Person”).  Any person or group that beneficially owned 20% or more of the outstanding shares of our Common Stock as of the first date of public announcement of the adoption of the Rights Agreement will not become an Acquiring Person unless and until such person or group acquires beneficial ownership of additional shares of Common Stock (other than beneficial ownership of any Common Stock which is acquired, whether in the form of options, restricted stock or other equity-linked securities, as compensation for services as an officer or director of the Company) representing one percent (1%) or more of the Common Stock then outstanding.
	The Rights Agreement provides that if any person or group becomes an Acquiring Person, each holder of a Right (other than Rights held by an Acquiring Person) will become entitled to receive, upon exercise and payment of the Purchase Price, Preferred Stock or, at the option of Tredegar, Common Stock (or, in certain circumstances, cash, property or other securities of the Company) having a value equal to twice the amount of the Purchase Price.  In addition, in the event that, at any time following the date that a person or group acquires beneficial ownership of 20% or more of the outstanding shares of our Common Stock,  (i) Tredegar is acquired in a merger, statutory share exchange, or other business combination in which Tredegar is not the surviving corporation, or (ii) fifty percent (50%) or more of our assets or earning power is sold or transferred, each holder of a Right (other than Rights held by an Acquiring Person) shall thereafter have the right to receive, upon exercise and payment of the Purchase Price, common stock of the acquiring company (or comparable equity securities of an acquiring entity that is not a corporation) having a value equal to twice the Purchase Price.
	The Rights were scheduled to expire on June 30, 2019.  On February 19, 2014, our 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.

	STOCK OPTION AND STOCK AWARD PLANS
	We have one equity incentive plan under which stock options may be granted to purchase a specified number of shares of common stock at a price no lower than the fair market value on the date of grant and for a term not to exceed 10 years. In addition, we have one other equity incentive plan under which there are options that remain outstanding, but no future grants can be made. Prior to 2012, employee options ordinarily vest two years from the date of grant. Employee options granted in 2012 and thereafter ordinarily vest over a four year period, with a quarter of the options granted vesting on each year on the grant date anniversary. The option plans also permit the grant of stock appreciation rights (“SARs”), stock, restricted stock, stock unit awards and incentive awards. Restricted stock grants ordinarily vest three years from the date of grant based upon continued employment and/or the achievement of certain performance targets. No SARs have been granted since 1992 and none are currently outstanding.
	A summary of our stock options outstanding at December 31, 2013, 2012 and 2011, and changes during those years, is presented below:

Retirement Plans And Other Postretirement Benefits	'
	RETIREMENT PLANS AND OTHER POSTRETIREMENT BENEFITS
	We sponsor noncontributory defined benefit (pension) plans covering most 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 based on plan changes announced in 2006, pay for active participants of the plan was frozen as of December 31, 2007. Beginning in the first quarter of 2014, with the exception of plan participants at two of our U.S. manufacturing facilities, the plan will no longer accrue benefits associated with crediting employees for service, thereby freezing all future benefits under the plan.
	In addition to providing pension benefits, we provide 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. We eliminated prescription drug coverage for Medicare-eligible retirees as of January 1, 2006. Consequently, we are not eligible for any federal subsidies.
	The following tables reconcile the changes in benefit obligations and plan assets in 2013 and 2012, and reconcile the funded status to prepaid or accrued cost at December 31, 2013 and 2012:

	Net periodic benefit cost		$	13,718			$	8,109			$	2,296				$	193			$	202			$	185
	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. Pension and other postretirement liabilities for continuing operations of $50.3 million and $92.1 million are included in “Other noncurrent liabilities” in the consolidated balance sheets at December 31, 2013 and 2012, respectively. The amount of our accumulated benefit obligation is the same as our projected benefit obligation.
	At December 31, 2013, the effect of a 1% change in the health care cost trend rate assumptions would be immaterial.
	Expected benefit payments for continuing operations over the next five years and in the aggregate for 2019-2023 are as follows:
	(In Thousands)	Pension				Other Post-
		Benefits				Retirement

	2018	16,748				533
	2019—2023	89,586				2,696
	Amounts recognized in 2013, 2012 and 2011 before related deferred income taxes in accumulated other comprehensive income consist of:
		Pension												Other Post-Retirement

	As a result of the decrease in the discount rate and freezing all future service benefits for certain plan participants, pension expense is expected to be $7.5 million in 2014. The amounts before related deferred income taxes in accumulated other comprehensive income that are expected to be recognized as components of net periodic benefit or cost during 2014 are as follows:

Our targeted allocation percentage for pension plan assets and the expected long-term rate of return on assets is as follows:
	Target % Composition of Plan Assets *			Expected Long-term Return %
Pension plans related to continuing operations:
Fixed income securities	32	%		5.5	%
Large/mid-capitalization equity securities	10			9.2

Total equity securities	27			9.9
Private equity and hedge funds	41			8.1
Total for continuing operations	100	%		7.8	%
*	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. Other assets are primarily comprised of cash and contracts with insurance companies. Our primary investment objective is to maximize total return with a strong emphasis on the preservation of capital. We believe 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 our pension plans is about 11.4 years. We expect our required contributions to be approximately $0.2 million in 2014.
Estimates of the fair value of assets held by our pension plans are provided by third parties not affiliated with Tredegar. At December 31, 2013, the pension plan assets are categorized by level within the fair value measurement hierarchy as follows:

We also have 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 our principal pension plans if it were not for limitations imposed by income tax regulations. The projected benefit obligation relating to this unfunded plan was $2.4 million at December 31, 2013 and $2.8 million at December 31, 2012. Pension expense recognized for this plan was $0.1 million in 2013, $0.1 million in 2012 and $0.1 million in 2011. This information has been included in the preceding pension benefit tables.
Approximately 98 employees at our films 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 $0.5 million in 2013, $0.5 million in 2012 and $0.6 million in 2011. This information has been excluded from the preceding pension benefit tables.

	SAVINGS PLAN
	We have a savings plan that allows eligible employees to voluntarily contribute a percentage of their compensation up to Internal Revenue Service (“IRS”) limitations. Effective January 1, 2007, 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 maximum matching contribution is currently 5% of base pay.
	•	The savings plan includes immediate vesting for active employees of past matching contributions as well as future matching contributions when made (compared with the previous 5-year graded vesting) and automatic enrollment at 3% of base pay unless the employee opts out or elects a different percentage.
	We also have 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 $2.6 million in 2013, $2.5 million in 2012 and $2.5 million in 2011. Our liability under the restoration plan was $2.2 million at December 31, 2013 (consisting of 75,726 phantom shares of common stock) and $1.6 million at December 31, 2012 (consisting of 78,615 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 our common stock in 1998 for $0.2 million and 46,671 shares of our 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 1997 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.

	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 Ltda. (6.25% of income tax and 9.0% social contribution on income). The current incentives will expire at the end of 2014, but we anticipate that we will qualify for additional incentives that will extend beyond 2014. The benefit from the tax incentives was $2.5 million (8 cents per share), $4.3 million (13 cents per share) and $0.7 million (2 cents per share) in 2013, 2012 and 2011, respectively.

Except as noted below, we believe that it is more likely than not that future taxable income will exceed future tax deductible amounts thereby resulting in the realization of deferred tax assets. A valuation allowance of $1.7 million at December 31, 2013 and $1.3 million at December 31, 2012, respectively, is recorded against the tax benefit on state and foreign net operating loss carryforwards for possible future tax benefits on domestic state and foreign operating losses generated by certain foreign and domestic subsidiaries that may not be recoverable in the carry-forward period. In addition, the valuation allowance for excess capital losses from investments and other related items was increased from $15.5 million at December 31, 2012 to $16.4 million at December 31, 2013 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. The valuation allowance for asset impairments in foreign jurisdictions where we believe it is more likely than not that the deferred tax asset will not be realized was $1.9 million in 2013 and 2012.

Tredegar and its subsidiaries file income tax returns in the U.S., various states and jurisdictions outside the U.S. With few exceptions, Tredegar and its subsidiaries are no longer subject to state or non-U.S. income tax examinations by tax authorities for years before 2010. We believe that it is reasonably possible that approximately $1.0 million of the balance of unrecognized state tax positions may be recognized within the next twelve months as a result of a lapse of the statute of limitations.

	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 our 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 shutdown of the 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 film products 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 Film Products 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 our 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 our 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 our 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 our investment that is not expected to be temporary. We also recorded an unrealized loss on our 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 our investment that is not expected to be temporary. See Note 4 for additional information on investments.
	We have announced that we will be closing our film products manufacturing facility in Red Springs, North Carolina in June 2014. The plant, which is a leased facility, is solely dedicated to producing babycare elastic laminate films for P&G, and P&G has informed us that we will lose this volume when it consolidates its suppliers for North American product needs. The Red Springs manufacturing facility currently employs 66 people, and we estimate that charges incurred related to the shutdown, which primarily consist of severance and other employee-related costs, will be approximately $1.3 million.
	Losses associated with plant shutdowns, asset impairments, restructurings and other charges for continuing operations in 2012 (as shown in the segment operating profit table in Note 5) totaled $5.5 million ($3.6 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 2012 included:
	•	A fourth quarter charge of $0.9 million ($0.5 million after taxes), a third quarter charge of $0.8 million ($0.5 million after taxes), a second quarter charge of $1.0 million ($0.7 million after taxes) and a first quarter charge of $0.9 million ($0.5 million after taxes) associated with the shutdown of the aluminum extrusions manufacturing facility in Kentland, Indiana, which includes accelerated depreciation for property, plant and equipment of $2.4 million (included in “Cost of goods sold” in the consolidated statements of income), severance and other employee related expenses of $1.2 million and other shutdown-related charges of $2.3 million, partially offset by adjustments to inventories accounted for under the LIFO method of $1.5 million (included in “Cost of goods sold” in the consolidated statements of income) and gains on the sale of equipment of $0.8 million (included in “Other income (expense), net” in the consolidated statements of income);
	•	A fourth quarter gain of $1.3 million ($0.7 million after taxes) in Film Products (included in “Other income (expense), net” in the consolidated statements of income) associated with an insurance recovery on idle equipment that was destroyed in a fire at an outside warehouse;
	•	A fourth quarter charge of $0.9 million ($0.6 million after taxes) and a third quarter charge of $0.3 million ($0.2 million after taxes) for acquisition-related expenses (included in “Selling, general and administrative expenses” in the consolidated statements of income) associated with the acquisition of AACOA by Aluminum Extrusions (see discussion below for further detail);
	•	A fourth quarter charge of $0.1 million ($0.1 million after taxes), a third quarter charge of $0.1 million ($0.1 million after taxes), a second quarter charge of $0.6 million ($0.4 million after taxes) and a first quarter charge of $0.3 million ($0.2 million after taxes) for integration-related expenses (included in “Selling, general and administrative expenses” in the consolidated statements of income) associated with the Film Products acquisition of Terphane;
	•	A fourth quarter gain of $1.1 million ($0.6 million after taxes) related to the sale of a previously shutdown film products manufacturing facility in LaGrange, Georgia;
	•	A second quarter charge of $0.8 million ($0.5 million after taxes) for asset impairments associated with a previously shutdown film products manufacturing facility in LaGrange, Georgia;
	•	A fourth quarter charge of $0.2 million ($0.1 million after taxes) and a second quarter charge of $0.1 million ($46,000 after taxes) in Film Products and a first quarter charge of $0.2 million ($0.1 million after taxes) in Aluminum Extrusions for severance and other employee-related costs in connection with restructurings;
	•	A fourth quarter charge of $0.2 million ($0.2 million after taxes) for asset impairments in Film Products;
	•	A fourth quarter charge of $0.2 million ($0.1 million after taxes) for integration-related expenses (included in “Selling, general and administrative expenses” in the consolidated statements of income) associated with the Aluminum Extrusions’ acquisition of AACOA;
	•	A fourth quarter charge of $0.1 million ($0.1 million after taxes) associated with purchase accounting adjustments made to the value of inventory sold by Aluminum Extrusions after its acquisition of AACOA (included in “Cost of goods sold” in the consolidated statements of income); and
	•	A fourth quarter charge of $0.1 million ($49,000 after taxes) related to expected future environmental costs at our aluminum extrusions manufacturing facility in Newnan, Georgia (included in “Cost of goods sold” in the consolidated statements of income).
	Total acquisition-related expenses (included in “Selling, general and administrative expenses” in the consolidated statements of income) associated with the acquisition of AACOA by Aluminum Extrusions were $2.0 million in 2012. Acquisition-related expenses of $0.8 million were recorded to “Corporate expenses, net” in the segment operating profit table in Note 5 during the first and second quarters of 2012, and as noted above, acquisitions-related expenses of $1.2 million were recorded to “Losses associated with plant shutdowns, asset impairments, restructurings and other charges” for Aluminum Extrusions in the segment operating profit table in Note 5 during the third and fourth quarters of 2012.
	Results in 2012 include an unrealized gain from our investment in kaléo of $16.1 million ($10.2 million after taxes), which is accounted for under the fair value method. An unrealized loss on our investment in Harbinger of $1.1 million ($0.7 million after taxes) was recorded in 2012 as a result of a reduction in the fair value of our investment that is not expected to be temporary. See Note 4 for additional information on investments.
	Aluminum Extrusions closed its manufacturing facility in Kentland, Indiana in August 2012. The plant, whose core market was residential construction, previously employed 146 people. We estimate that charges incurred related to the shutdown will be approximately $4.5 million, and include accelerated depreciation on property, plant and equipment of approximately $2.4 million, severance and other employee-related charges of approximately $1.2 million and other shutdown-related costs of approximately $1 million. Other shutdown-related costs are primarily comprised of equipment transfers and plant shutdown charges, partially offset by adjustment for inventories accounted for under the LIFO method. Most of these shutdown charges, which include cash expenditures of approximately $3.5 million, are expected to be recognized over a period of 18 months.
	Losses associated with plant shutdowns, asset impairments, restructurings and other charges for continuing operations in 2011 (as shown in the segment operating profit table in Note 5) totaled $6.8 million ($0.3 million gain 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 2011 included:
	•	A fourth quarter charge of $2.5 million ($2.2 million after taxes) and a third quarter charge of $2.3 million ($2.2 million after taxes) for acquisition-related expenses (included in “Selling, general and administrative expenses” in the consolidated statements of income) associated with the Film Products acquisition of Terphane;
	•	A fourth quarter charge of $0.6 million ($0.4 million after taxes) and a second quarter charge of $0.8 million ($0.5 million after taxes) for asset impairments in Film Products;
	•	A third quarter gain of $1.0 million ($6.6 million after taxes) on the divestiture of our film products business in Roccamontepiano, Italy (included in “Other income (expense), net” in the consolidated statements of income), which includes the recognition of previously unrealized foreign currency translation gains of $4.3 million that were associated with the business;
	•	A fourth quarter charge of $0.7 million ($0.5 million after taxes) associated with purchase accounting adjustments made to the value of inventory sold by Film Products after its purchase of Terphane (included in “Cost of goods sold” in the consolidated statements of income);
	•	A fourth quarter charge of $0.1 million ($39,000 after taxes), a third quarter charge of $0.2 million ($0.1 million after taxes) and a second quarter charge of $0.3 million ($0.2 million after taxes) for severance and other employee-related costs in connection with restructurings in Film Products;
	•	A fourth quarter charge of $0.4 million ($0.3 million after taxes) for integration-related expenses (included in “Selling, general and administrative expenses” in the consolidated statements of income) associated with the Film Products acquisition of Terphane; and
	•	A fourth quarter benefit of $39,000 ($24,000 after taxes), a third quarter charge of $43,000 ($27,000 after taxes), a second quarter benefit of $0.1 million ($0.1 million after taxes), and a first quarter charge of $32,000 ($20,000 after taxes) for timing differences between the recognition of realized losses on aluminum futures contracts and related revenues from the delayed fulfillment by customers of fixed-price forward purchase commitments (included in “Cost of goods sold” in the consolidated statements of income).
	Results in 2011 include an unrealized gain on our investment in kaléo of $1.6 million ($1.0 million after taxes), which is accounted for under the fair value method. An unrealized loss on our investment in Harbinger of $0.6 million ($0.4 million after taxes) was recorded in 2011 as a result of a reduction in the fair value of our investment that is not expected to be temporary. See Note 4 for additional information on investments.
	The estimated fair value of machinery and equipment that was evaluated for impairment was primarily based on our estimates of the proceeds that we would receive if and/or when assets are sold. Our 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.
	The impairment charges in Film Products 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 our estimates of the proceeds that we would receive if and/or when assets are sold. Our 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 generally accepted accounting principles.

Where we have determined the nature and scope of any required environmental remediation activity, estimates of cleanup costs have been obtained and accrued. As we continue efforts to maintain compliance with applicable environmental laws and regulations, additional contingencies may be identified. If additional contingencies are identified, our practice is to determine the nature and scope of those contingencies, obtain and accrue estimates of the cost of remediation, and perform remediation. We do not believe that additional costs that could arise from those activities will have a material adverse effect on our financial position. However, those costs could have a material adverse effect on quarterly or annual operating results at that time.
	We are involved in various other legal actions arising in the normal course of business. After taking into consideration information we deemed relevant, we believe that we have sufficiently accrued for probable losses and that the actions will not have a material adverse effect on our 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, we enter into transactions with third parties in connection with the sale of assets or businesses in which we agree 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 us, for certain liabilities or risks related to the assets or business. Also, in the ordinary course of our business, we 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, we are unable to estimate the maximum potential amount of the potential future liability under the indemnity provisions of these agreements. We do, 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. We disclose contingent liabilities if the probability of loss is reasonably possible and material.
	In November 2009, the 3M Company (“3M”) filed a patent infringement complaint in the United States District Court for the District of Minnesota (“Minnesota District Court”) against our film products business. The complaint alleges infringement upon elastic film technology patents held by 3M and seeks unspecified compensatory and enhanced damages associated with our sales of certain elastic film product lines, which include our FabriFlex™ and FlexFeel™ family of products.
	Following the issuance of a “Markman” Memorandum Opinion by the Minnesota District Court in November 2011, 3M filed a stipulation of non-infringement related to this matter in February 2012. 3M then filed an appeal with the U.S. Federal Circuit Court of Appeals regarding the “Markman” Memorandum Opinion. In August 2013, the U.S. Federal Circuit Court of Appeals issued an opinion that remanded this patent infringement complaint back to the Minnesota District Court for further consideration. Despite this ruling, we believe that we have sufficient defenses to prevail, and we intend to defend our position vigorously. In the event that we do not prevail in this matter, we do not anticipate that any damages awarded to 3M, which would be in the form of a lump sum payment, will be material to our consolidated financial position. We expect to incur legal expenses of approximately $3 million in the next 12 to 18 months as we defend against this matter.
	In 2011, we were 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 antidumping duty order on imported PET films from Brazil. We contested the applicability of these antidumping duties to the films exported by Terphane, and we filed a request with the U.S. Department of Commerce (“Commerce”) for clarification about whether the film products at issue are within the scope of the antidumping 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 antidumping duties because Commerce’s scope ruling was overturned on appeal, or otherwise, indemnifications for related liabilities are specifically provided for under the Purchase Agreement.

Summary_Of_Significant_Account1

Summary Of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
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, we sold our aluminum extrusions business in Canada, and on November 20, 2012, we sold our mitigation banking business, Falling Springs, LLC (“Falling Springs”). All historical results for these businesses 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 us 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. We have no 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 not material in 2013, 2012 and 2011. These amounts do not include the effects between reporting periods that exchange rate changes have on income of our 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, 2013 and 2012, Tredegar had cash and cash equivalents of $52.6 million and $48.8 million, respectively, including funds held in locations outside the U.S. of $38.6 million and $28.6 million, respectively.
	Our 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 our 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 were not material in 2013, 2012 and 2011.
	Depreciation is computed primarily by the straight-line method based on the estimated useful lives of the assets, which except for certain isolated exceptions, range from 10 to 30 years for buildings and land improvements and 2 to 17 years for machinery and equipment. The average depreciation period for machinery and equipment is approximately 10 years in Film Products and for the continuing operations of Aluminum Extrusions.
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. We account for our investments in private entities where our voting ownership is less than or equal to 50% based on the facts and circumstances surrounding the investment. We are required to account for investments under the consolidation method in situations where we are 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. We are deemed to have a controlling financial interest if we have (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 we are not deemed to be the primary beneficiary in an investment in a variable interest entity then we select either: (i) the fair value method or (ii) either (a) the cost method if we do not have significant influence over operating and financial policies of the investee or (b) the equity method if we do 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. We assess 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 1st of each year). Our significant reporting units in Film Products include Polyethylene and Polypropylene Films and PET Films. We have two reporting units in Aluminum Extrusions, Bonnell Aluminum and AACOA. Each of our reporting units has separately identifiable operating net assets (operating assets including goodwill and intangible assets net of operating liabilities).
	All goodwill in Aluminum Extrusions is associated with the AACOA reporting unit. Based on the severity of the economic downturn and its impact on the sales volumes of our aluminum extrusions business, the resulting operating loss in the first quarter of 2009, possible future losses and the uncertainty in the amount and timing of an economic recovery, a goodwill impairment charge of $30.6 million ($30.6 million after taxes), which represented the entire goodwill balance in the Bonnell Aluminum reporting unit, was recognized in 2009.
	We estimate the fair value of our reporting units using discounted cash flow analysis and comparative enterprise value-to-EBITDA (earnings before interest, taxes, depreciation and amortization) multiples. The goodwill of Polyethylene and Polypropylene Films reporting unit was tested for impairment at the annual testing date, with the estimated fair value of this reporting unit substantially exceeding the carrying value of its net assets. The goodwill of PET Films reporting unit was also tested for impairment at December 1, 2013, with the estimated fair value of this reporting unit exceeding the carrying value of its net assets by approximately 37%. The goodwill of AACOA is associated with the October 2012 acquisition of AACOA, Inc. (“AACOA”), and estimated fair value of this reporting unit exceeded the carrying value of its net assets by approximately 22% at December 1, 2013.
Impairment Of Long-Lived Assets	'
	Impairment of Long-Lived Assets. We review 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, we estimate 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. We recognize the funded status of our pension and other postretirement plans in the accompanying consolidated balance sheets. Our policy is to fund our 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 Ltda. (a subsidiary of Film Products) because of our intent to permanently reinvest these earnings. We have not recorded a deferred liability of approximately $7.1 million related to the U.S. federal income taxes and foreign withholding taxes on approximately $36.0 million of undistributed earnings indefinitely invested outside the U.S. at December 31, 2013. We accrue U.S. federal income taxes on unremitted earnings of all other foreign subsidiaries. The benefit of an uncertain tax position is included in the accompanying financial statements when we determine 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:
		2013			2012			2011
	Weighted average shares outstanding used to compute basic earnings per share	32,171,751			32,032,343			31,931,962
	Incremental shares attributable to stock options and restricted stock	427,528			160,233			281,212
	Shares used to compute diluted earnings per share	32,599,279			32,192,576			32,213,174
	Incremental shares attributable to stock options and restricted stock are computed using the average market price during the related period. During 2013, 2012 and 2011, 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 was 31,167, 632,050 and 293,704, respectively.
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 our closing stock price on that date.
	The assumptions used in this model for valuing Tredegar stock options granted in 2013, 2012 and 2011 are as follows:
		2013				2012			2011
	Dividend yield	1.1		%		0.9		%	0.9		%
	Weighted average volatility percentage	48.3		%		48.7		%	46.4		%
	Weighted average risk-free interest rate	1.1		%		1		%	2.5		%
	Holding period (years):
	Officers	6				6			6
	Management	5				5			5
	Weighted average exercise price at date of grant (also weighted average market price at date of grant):
	Officers	$	24.84			$	19.3		$	19.84
	Management	25.1				19.4			19.73
	The dividend yield is the dividend yield on our common stock at the date of grant, which we believe is a reasonable estimate of the expected yield during the holding period. We calculate expected volatility based on the historical volatility of our common stock using a sequential period of historical data equal to the expected holding period of the option. We have 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. We use derivative financial instruments for the purpose of hedging aluminum price volatility and currency exchange rate exposures that exist as part of transactions associated with our ongoing business operations. Our 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 as 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 2013, 2012 and 2011.
	Our policy requires that we formally document all relationships between hedging instruments and hedged items, as well as our risk management objective and strategy for undertaking various hedge transactions. We also formally assess (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, we discontinue hedge accounting prospectively.
	As a policy, we do not engage in speculative or leveraged transactions, nor do we hold or issue financial instruments for trading purposes. Additional disclosure of our 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 and other comprehensive income or loss. 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 gains or losses adjustments, all recorded net of deferred income taxes.
Recently Issued Accounting Standards	'
	Recently Issued Accounting Standards. In February 2013, the Financial Accounting Standards Board (“FASB”) issued updated guidance to address the recognition, measurement and disclosure of obligations resulting from joint and several liability arrangements for which the total amount under the arrangement is fixed at the reporting date. Under the new guidance, an entity would measure its obligation from a joint and several liability arrangement as the sum of the amount the entity agreed with its co-obligors that it will pay, and any additional amount the entity expects to pay on behalf of its co-obligors. The standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2013. Early application is permitted, and we do not expect the guidance to impact us.
	In March 2013, the FASB issued updated guidance related to foreign currency matters. The updated guidance attempts to resolve the diversity in practice about the release of the cumulative translation adjustment into net income when a parent either sells a part or all of its investment in a foreign entity or no longer holds a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity. In addition, the amended guidance attempts to resolve the diversity in practice for the treatment of business combinations achieved in stages involving a foreign entity. The guidance is effective for the first annual period beginning after December 15, 2013, and we do expect the guidance to impact us.
	In July 2013, the FASB issued new guidance regarding the presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists.  The new guidance requires an unrecognized tax benefit to be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, unless certain exceptions are met.  The amendments are effective prospectively for fiscal and interim periods beginning after December 15, 2013. We are still assessing the applicability of this guidance in future periods.
