Basis Of Presentation [Abstract]
Basis Of Presentation	In the opinion of management, the accompanying consolidated financial statements of Tredegar Corporation and its subsidiaries (“Tredegar,” “the Company,” “we,” “us” or “our”) contain all adjustments necessary to state fairly, in all material respects, Tredegar’s consolidated financial position as of September 30, 2017 , the consolidated results of operations for the three and nine months ended September 30, 2017 and 2016 , the consolidated cash flows for the nine months ended September 30, 2017 and 2016 , and the consolidated changes in shareholders’ equity for the nine months ended September 30, 2017 . All such adjustments, unless otherwise detailed in the notes to the consolidated interim financial statements, are deemed to be of a normal, recurring nature. The Company operates on a calendar fiscal year except for the Aluminum Extrusions segment, which operates on a 52/53-week fiscal year basis. As such, the fiscal third quarter for 2017 and 2016 for this segment references 13-week periods ended September 24, 2017 and September 25, 2016, respectively. The Company does not believe the impact of reporting the results of this segment as stated above is material to the consolidated financial results. The financial position data as of December 31, 2016 that is included herein was derived from the audited consolidated financial statements provided in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 (“ 2016 Form 10-K”) but does not include all disclosures required by United States generally accepted accounting principles (“GAAP”). These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the Company’s 2016 Form 10-K. The results of operations for the three and nine months ended September 30, 2017 , are not necessarily indicative of the results to be expected for the full year. Certain prior year balances have been reclassified to conform with current year presentation (see Note 13 for additional detail).

Acquisitions

Acquisitions	9 Months Ended

Business Combinations [Abstract]
Acquisitions	On February 15, 2017, Bonnell Aluminum acquired 100% of the stock of Futura Industries Corporation (“Futura”) on a net debt-free basis for approximately $92 million (the “Initial Purchase Price”). The amount actually funded in cash at the transaction date was approximately $87.0 million (the “Initial Cash Funding”), which was the Initial Purchase Price net of preliminary closing adjustments for working capital and seller transaction-related obligations assumed and subsequently paid by Bonnell Aluminum. The acquisition, which was funded using Tredegar’s existing revolving credit facility, was treated as an asset purchase for U.S. federal income tax purposes. Futura, headquartered in Clearfield, Utah, with a national sales presence and particular strength in the western U.S., designs and manufactures a wide range of extruded aluminum products, including branded flooring trims and TSLOTS TM , as well as OEM (original equipment manufacturer) components for truck grills, solar panels, fitness equipment and other applications. As a result of this transaction, Futura is now a wholly-owned subsidiary of the William L. Bonnell Company, Inc. (which is a wholly-owned subsidiary of Tredegar) and operates as a division of Bonnell Aluminum, and its results of operations are included in Tredegar’s consolidated financial statements from the date of acquisition. Under the terms of the transaction, $5 million of the Initial Cash Funding was placed in escrow (the “Earnout Escrow”) and will be returned to Bonnell Aluminum if Futura does not achieve a targeted EBITDA level (as defined in the Stock Purchase Agreement) for the last eleven months of the fiscal year ending December 2017. At the acquisition date, the Company performed a probability weighted assessment in order to determine the fair value of this contingent asset. The assessment estimated a fair value of $4.3 million , which would be returned to Bonnell Aluminum in early 2018, and accordingly, a receivable of $4.3 million (“Initial Earnout Receivable”) was recorded by Bonnell Aluminum. In the second quarter of 2017, the Company updated its valuation of this contingent asset, which resulted in a fair value of $5.0 million . The receivable was increased to $5.0 million , and $0.7 million was recognized as income in Other income (expense), net in the Consolidated Statements of Income. The net purchase price for financial reporting purposes was set at approximately $82.9 million (the “Adjusted Net Purchase Price”), which was the Initial Cash Funding less the Initial Earnout Receivable and the net settlement of certain post-closing adjustments of $0.1 million paid to the seller during the second quarter of 2017. Adjustments to the purchase price were made retrospectively as if the accounting had been completed on the acquisition date. Based upon management’s valuation of the fair value of tangible and intangible assets acquired (net of cash acquired) and liabilities assumed, the allocation of the Adjusted Net Purchase Price is as follows: (in Thousands) Accounts receivable $ 6,680 Inventories 10,342 Prepaid expenses and other current assets 240 Property, plant & equipment 32,662 Identifiable intangible assets: Customer relationships 24,000 Trade names 6,700 Trade payables & accrued expenses (8,135 ) Total identifiable net assets 72,489 Adjusted Net Purchase Price 82,860 Goodwill $ 10,371 The goodwill and other intangible asset balances associated with this acquisition will be deductible for tax purposes on a straight-line basis over a period of approximately 15 years. For financial reporting purposes, customer relationships are being amortized over 12 years and trade names are being amortized over 13 years. Goodwill is not subject to amortization for financial reporting purposes. Customer relationships were valued using the excess earnings approach. Trade names were valued using a relief-from-royalty approach. The Company does not anticipate marketing Futura’s products under a different brand in light of its strong name recognition and competitive advantage in its target markets. For the three and nine month periods ended September 30, 2017 (for Futura, the period from the acquisition on February 15, 2017 to September 30, 2017 ), Tredegar’s consolidated results of operations and its Aluminum Extrusions business segment included the following Futura results: sales of $21.2 million and $52.0 million , respectively, operating profit from ongoing operations of $2.4 million and $6.2 million , respectively, depreciation and amortization of $1.7 million and $3.6 million , respectively, and capital expenditures of $0.5 million and $1.3 million , respectively. The following unaudited supplemental pro forma data presents Tredegar’s consolidated sales, net income and related earnings per share as if the acquisition of Futura had been consummated at the beginning of 2016, and is not necessarily indicative of the Company’s financial performance if the acquisition had actually been consummated as of that date, or of future performance. The supplemental unaudited pro forma measures for the three and nine months ended September 30, 2017 and 2016 are presented below: Tredegar Pro Forma Results with Futura Acquisition Three Months Ended Nine Months Ended September 30, September 30, (In Thousands, Except Per Share Data) 2017 2016 2017 2016 Sales $ 247,121 $ 228,176 $ 722,505 $ 681,686 Net income $ 8,274 $ 13,225 $ 55,835 $ 25,559 Earnings per share: Basic $ 0.25 $ 0.40 $ 1.69 $ 0.78 Diluted $ 0.25 $ 0.40 $ 1.69 $ 0.78 Futura’s pre-acquisition results for the period from January 1 to February 14, 2017, and therefore the pro forma information for 2017 presented above, were adversely impacted by significant disruptions to manufacturing operations and sales caused by the renovation of its anodizing line. The actual accretion to Tredegar’s diluted earnings per share from Futura since the acquisition date was four cents per share f or the third quarter of 2017 and nine cents per share for the first nine months of 2017. The Company’s pro forma net income was computed for the periods shown as: (i) the Company’s reported net income, plus (ii) Futura’s historical pre-acquisition period earnings before interest, taxes, depreciation and amortization and excluding one-time purchase accounting and transaction-related expenses, minus (iii) the pro forma pre-acquisition period depreciation and amortization for Futura under purchase accounting for the Company, minus (iv) the pro forma pre-acquisition period interest expense for the Company applied at an annual rate of 3.0% to the $87.0 million Initial Cash Funding, minus (v) the pro forma pre-acquisition period income taxes applied at a rate of 39.1% to the pro forma pre-acquisition earnings before income taxes computed from items (ii) through (iv).

(“kaléo”), which is accounted for under the fair value method (included in “Other income (expense), net” in the consolidated statements of income). There was no change in the estimated fair value from June 30, 2017 to September 30, 2017, as appreciation in value from the discount rate for one quarter was offset by a change in the present value of projected cash flows versus prior projections. The change in the first nine months of 2017 in the estimated fair value of the Company’s holding in kaléo was based primarily on changes in projected future cash flows that are discounted at 45% for their high degree of risk. See Note 7 for additional information on investments. A reconciliation of the beginning and ending balances of accrued expenses associated with exit and disposal activities and charges associated with asset impairments and reported as “Asset impairments and costs associated with exit and disposal activities, net of adjustments” in the consolidated statements of income for the nine months ended September 30, 2017 is as follows: (In Thousands) Severance (a) Asset Impairments Other (b) Total Balance at January 1, 2017 $ 1,854 $ — $ 554 $ 2,408 Changes in 2017: Charges 300 50 303 653 Cash spent (1,068 ) — (307 ) (1,375 ) Charges against assets — (50 ) — (50 ) Balance at September 30, 2017 $ 1,086 $ — $ 550 $ 1,636 (a) Severance primarily includes severance payments associated with the consolidation of North American PE Films manufacturing facilities. (b) Other primarily includes other shutdown-related costs associated with the shutdown and sale of the Company’s aluminum extrusions manufacturing facility in Kentland, Indiana. In July 2015, the Company began a consolidation of its domestic production for PE Films by restructuring the operations in its manufacturing facility in Lake Zurich, Illinois. This restructuring was completed in the third quarter of 2017. Total expenses associated with the restructuring were $0.8 million in the first nine months of 2017 (included in “Cost of goods sold” in the consolidated statements of income) and the total expenses for the project since inception were $7.3 million . Cash expenditures for the restructuring were $1.4 million in the first nine months of 2017 , which includes capital expenditures of $0.1 million . Total cash expenditures for the project since inception were $15.5 million , which includes $11.2 million for capital expenditures. Additional cash payments for remaining accrued costs of approximately $1 million are expected to be paid within the next 12 months.

Equity Method Investments and Joint Ventures [Abstract]
Investments	In August 2007 and December 2008, the Company made an aggregate investment of $7.5 million in kaléo, a privately held specialty pharmaceutical company dedicated to building innovative solutions for serious and life-threatening medical conditions. Tredegar’s ownership interest on a fully diluted basis was approximately 20% at September 30, 2017 , and the investment is accounted for under the fair value method. At the time of the initial investment, the Company elected the fair value option over the equity method of accounting since its investment objectives were similar to those of venture capitalists, which typically do not have controlling financial interests. The estimated fair value of the investment in kaléo (also the carrying value, which is included in “Other assets and deferred charges” in the consolidated balance sheets) was $45.0 million at September 30, 2017 and $20.2 million at December 31, 2016 . An unrealized loss of $1.3 million was recognized in the third quarter of 2016 . Unrealized gains of $24.8 million and an unrealized loss of $0.2 million were recognized in the first nine months of 2017 and 2016 , respectively. There was no change in the estimated fair value from June 30, 2017 to September 30, 2017, as appreciation in value from the discount rate for one quarter was offset by a change in the present value of projected cash flows versus prior projections. 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 net sales and operating profit by segment table in Note 10. The change in the estimated fair value of the Company’s holding in kaléo in the first nine months of 2017 primarily related to recent favorable operating results and projections. Kaléo’s stock is not publicly traded. In addition, kaléo has not completed a full year of operations since the re-launch of its Auvi-Q ® product during the first quarter of 2017. The valuation estimate in this situation is based on projection assumptions or Level 3 inputs that have a wide range of possible outcomes. Consequently, the present value of kaléo’s projected future cash flows is determined at a discount rate of 45% for their high degree of risk. Ultimately, the true value of the Company’s ownership interest in kaléo will be determined if and when a liquidity event occurs, and the ultimate value could be materially different from the $45.0 million estimated fair value reflected in the Company’s financial statements at September 30, 2017 . In addition to the impact on valuation of the possible changes in assumptions, Level 3 inputs and projections from changes in business conditions, the fair market valuation of the Company’s interest in kaléo is sensitive to changes in the weighted average cost of capital used to discount cash flow projections. The weighted average cost of capital used in the fair market valuation of Tredegar’s interest in kaléo was 45% at both September 30, 2017 and December 31, 2016 . At September 30, 2017 , the effect of a 500 basis point decrease in the weighted average cost of capital assumption would have increased the fair value of the Company’s interest in kaléo by approximately $9 million , and a 500 basis point increase in the weighted average cost of capital assumption would have decreased the fair value of the Company’s interest by approximately $8 million . Had the Company not elected to account for its investment under the fair value method, it would have been required to use the equity method of accounting. The condensed balance sheets for kaléo at September 30, 2017 and December 31, 2016 and condensed statements of operations for the three and nine months ended September 30, 2017 and 2016 , as reported to the Company by kaléo, are provided below: Unaudited (In Thousands) September 30, 2017 December 31, 2016 September 30, 2017 December 31, 2016 Assets: Liabilities & Equity: Cash & short-term investments $ 104,753 $ 102,329 Restricted cash 31 31 Current liabilities $ 85,086 $ 50,134 Other current assets 39,059 15,391 Long term debt, net 138,305 143,380 Property & equipment 10,399 13,011 Other noncurrent liabilities 807 822 Other long-term assets 494 472 Equity (69,462 ) (63,102 ) Total assets $ 154,736 $ 131,234 Total liabilities & equity $ 154,736 $ 131,234 Three Months Ended September 30, Nine Months Ended September 30, Unaudited (In Thousands) 2017 2016 2017 2016 Revenues $ 58,822 $ 17,377 $ 148,761 $ 29,347 Cost of goods sold, R&D and SG&A expenses before depreciation & amortization (52,072 ) (19,046 ) (137,411 ) (50,442 ) Depreciation & amortization (1,245 ) (1,278 ) (3,723 ) (3,477 ) Operating income (loss) 5,505 (2,947 ) 7,627 (24,572 ) Gain on contract termination — — — 18,075 Net interest expense and other net (4,767 ) (4,848 ) (14,408 ) (14,535 ) Income tax benefit (expense) (244 ) — (734 ) (8 ) Net income (loss) $ 494 $ (7,795 ) $ (7,515 ) $ (21,040 ) The Company’s investment in the Harbinger Capital Partners Special Situations Fund, L.P. (“Harbinger Fund”) had a carrying value (included in “Other assets and deferred charges”) of $1.7 million at September 30, 2017 and December 31, 2016 . The carrying value at September 30, 2017 reflected Tredegar’s cost basis in its investment in the Harbinger Fund, net of total withdrawal proceeds received and unrealized losses. No withdrawal proceeds were received in the first nine months of 2016 or 2017. The timing and amount of future installments of withdrawal proceeds, which commenced in August 2010, were not known as of September 30, 2017 . Gains on the Company’s investment in the Harbinger Fund will be recognized when the amounts expected to be collected from any withdrawal from the investment are known, which will likely be when cash in excess of the remaining carrying value is received. Losses will be recognized when management believes it is probable that future withdrawal proceeds will not exceed the remaining carrying value.

Derivative Financial Instrument

Derivative Financial Instruments	9 Months Ended

Summary of Derivative Instruments [Abstract]
Derivative Financial Instruments	Tredegar uses derivative financial instruments for the purpose of hedging margin exposure from fixed-price forward sales contracts in Aluminum Extrusions and currency exchange rate exposures that exist as part of ongoing PE Films and Flexible Packaging Films business operations. These derivative financial instruments are designated as and qualify as cash flow hedges and are recognized in the consolidated balance sheet at fair value. The fair value of derivative instruments recorded on the consolidated balance sheets are based upon Level 2 inputs. If individual derivative instruments with the same counterparty can be settled on a net basis, the Company records the corresponding derivative fair values as a net asset or net liability. In the normal course of business, Aluminum Extrusions enters into fixed-price forward sales contracts with certain customers for the future sale of fixed quantities of aluminum extrusions at scheduled intervals. In order to hedge margin exposure created from the fixing of future sales prices relative to volatile raw material (aluminum) costs, Aluminum Extrusions enters into a combination of forward purchase commitments and futures contracts to acquire or hedge aluminum, based on the scheduled purchases for the firm sales commitments. The fixed-price firm sales commitments and related hedging instruments generally have durations of not more than 12 months, and the notional amount of aluminum futures contracts that hedged future purchases of aluminum to meet fixed-price forward sales contract obligations was $7.1 million ( 7.4 million pounds of aluminum) at September 30, 2017 and $8.0 million ( 9.6 million pounds of aluminum) at December 31, 2016 . The table below summarizes the location and gross amounts of aluminum futures contract fair values in the consolidated balance sheets as of September 30, 2017 and December 31, 2016 : September 30, 2017 December 31, 2016 (In Thousands) Balance Sheet Account Fair Value Balance Sheet Account Fair Value Derivatives Designated as Hedging Instruments Asset derivatives: Prepaid expenses and other $ 792 Prepaid expenses and other $ 308 Liability derivatives: Prepaid expenses and other $ (25 ) Prepaid expenses and other $ (37 ) Net asset (liability) $ 767 $ 271 In the event that a counterparty to an aluminum fixed-price forward sales contract chooses not to take delivery of its aluminum extrusions, the customer is contractually obligated to compensate Aluminum Extrusions for any losses on the related aluminum futures and/or forward contracts through the date of cancellation. The Company's earnings are exposed to foreign currency exchange risk primarily through the translation of the financial statements of subsidiaries that have a functional currency other than the U.S. Dollar. On September 29, 2017, the Flexible Packaging Films business unit in Brazil (“Terphane Ltda.”) entered into 15 monthly foreign exchange average forward rate contracts to purchase Brazilian Real (“R$”) and sell U.S. Dollars covering the period from October 2017 through December 2018. These foreign currency exchange contracts have been designated and qualify as cash flow hedges of Terphane Ltda.'s forecasted sales to customers quoted or priced in U.S. Dollars over that period. By changing the currency risk associated with these U.S. Dollar sales, the derivatives have the effect of offsetting operating costs quoted or priced in Brazilian Real and decreasing the net exposure to Brazilian Real in the consolidated statements of income. The aggregate notional amount of open foreign exchange contracts at September 30, 2017 was $18.75 million (R $60.7 million ). The forward rates contracted and the related market rates as of September 30, 2017 were the same, and accordingly the fair value of all 15 open forward contracts were zero at that date. These derivative contracts involve elements of market risk that are not reflected on the consolidated balance sheet, including the risk of dealing with counterparties and their ability to meet the terms of the contracts. The counterparties to any forward purchase commitments are major aluminum brokers and suppliers, and the counterparties to any aluminum futures contracts are major financial institutions. Fixed-price forward sales contracts are only made available to the best and most credit-worthy customers. The counterparties to the Company’s foreign currency cash flow hedge contracts are major financial institutions. The 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 the three and nine month periods ended September 30, 2017 and 2016 is summarized in the table below: (In Thousands) Cash Flow Derivative Hedges Aluminum Futures Contracts Foreign Currency Forwards Three Months Ended September 30, 2017 2016 2017 2016 Amount of pretax gain (loss) recognized in other comprehensive income (loss) $ 757 $ (230 ) $ — $ — Location of gain (loss) reclassified from accumulated other comprehensive income (loss) into net income (loss) (effective portion) Cost of Cost of Cost of Cost of Amount of pretax gain (loss) reclassified from accumulated other comprehensive income (loss) to net income (loss) (effective portion) $ 231 $ (160 ) $ 15 $ 15 Aluminum Futures Contracts Foreign Currency Forwards Nine Months Ended September 30, 2017 2016 2017 2016 Amount of pre-tax gain (loss) recognized in other comprehensive income (loss) $ 1,281 $ (93 ) $ — $ — Location of gain (loss) reclassified from accumulated other comprehensive income (loss) into net income (loss) (effective portion) Cost of Cost of Cost of Cost of Amount of pre-tax gain (loss) reclassified from accumulated other comprehensive income (loss) to net income (loss) (effective portion) $ 785 $ (1,669 ) $ 46 $ 46 As of September 30, 2017 , the Company expects $0.5 million of unrealized after-tax gains on derivative instruments reported in accumulated other comprehensive income (loss) to be reclassified to earnings within the next 12 months. For the three and nine month periods ended September 30, 2017 and 2016 , net gains or losses realized, from previously unrealized net gains or losses on hedges that had been discontinued, were not material.

Pension And Other Post-Retireme

Pension And Other Post-Retirement Benefits	9 Months Ended

Retirement Benefits [Abstract]
Pension And Other Post-Retirement Benefits	The Company sponsors noncontributory defined benefit (pension) plans covering certain current and former employees. The plan for salaried and hourly employees currently in effect is 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 was closed to new participants and pay for active plan participants for benefit calculations was frozen as of December 31, 2007. With the exception of plan participants at one of Tredegar’s U.S. manufacturing facilities, the plan no longer accrues benefits associated with crediting employees for service, thereby freezing future benefits under the plan. The components of net periodic benefit cost for the pension and other post-retirement benefit programs reflected in consolidated results are shown below: Pension Benefits Other Post-Retirement Benefits Three Months Ended September 30, Three Months Ended September 30, (In Thousands) 2017 2016 2017 2016 Service cost $ 29 $ 54 $ 7 $ 8 Interest cost 3,103 3,263 73 67 Expected return on plan assets (3,743 ) (4,070 ) — — Amortization of prior service costs, gains or losses and net transition asset 2,996 3,135 (84 ) (49 ) Net periodic benefit cost $ 2,385 $ 2,382 $ (4 ) $ 26 Pension Benefits Other Post-Retirement Benefits Nine Months Ended September 30, Nine Months Ended September 30, 2017 2016 2017 2016 Service cost $ 145 $ 178 $ 25 $ 29 Interest cost 9,431 9,993 226 236 Expected return on plan assets (11,216 ) (12,027 ) — — Amortization of prior service costs, (gains) losses and net transition asset 9,241 9,903 (207 ) (144 ) Net periodic benefit cost $ 7,601 $ 8,047 $ 44 $ 121 Pension and other post-retirement liabilities were $90.0 million and $96.0 million at September 30, 2017 and December 31, 2016 , respectively ( $0.6 million included in “Accrued expenses” at September 30, 2017 and December 31, 2016 , with the remainder included in “Other noncurrent liabilities” in the consolidated balance sheets). The Company’s required contributions are expected to be approximately $6 million in 2017 . Contributions to the pension plan during the first nine months of 2017 were $4.4 million . Tredegar funds its other post-retirement benefits (life insurance and health benefits) on a claims-made basis, which the Company anticipates will be consistent with amounts paid for the year ended December 31, 2016 , or $0.3 million .

Income Tax Disclosure [Abstract]
Income Taxes	Tredegar recorded tax expense of $9.7 million on pretax net income of $65.8 million in the first nine months of 2017 . Therefore, the effective tax rate in the first nine months of 2017 was 14.7% , compared to 7.6% in the first nine months of 2016 . The significant differences between the U.S. federal statutory rate and the effective income tax rate for the nine months ended September 30, 2017 and 2016 are as follows: Percent of Income Before Income Taxes Nine Months Ended September 30, 2017 2016 Income tax expense at federal statutory rate 35.0 35.0 Foreign rate differences 1.5 1.1 State taxes, net of federal income tax benefit 1.3 0.7 Changes in estimates related to prior year tax provision 0.5 (1.6 ) Non-deductible expenses 0.5 1.6 Valuation allowance for foreign operating loss carry-forwards 0.4 0.3 Unremitted earnings from foreign operations 0.2 (1.1 ) Valuation allowance for capital loss carry-forwards — (0.4 ) Income tax contingency accruals and tax settlements (0.4 ) 1.3 Remitted earnings from foreign operations (0.6 ) (23.8 ) Research and development tax credit (0.7 ) (1.8 ) Domestic production activities deduction (0.9 ) (3.8 ) Foreign investment write-up (3.5 ) 0.1 Settlement of Terphane acquisition escrow (6.4 ) — Worthless stock deduction (12.2 ) — Effective income tax rate 14.7 7.6 During the second quarter of 2017, the Company initiated a plan to liquidate for tax purposes one of its domestic subsidiaries, which will allow it to claim an income tax benefit on the write-off of the stock basis of one of the Company’s U.S. subsidiaries (“worthless stock deduction”) on its 2017 federal income tax return. The Company recorded an income tax benefit during the second quarter of 2017 of $8.1 million related to the worthless stock deduction, net of valuation allowances and accrual for uncertain tax positions. Tredegar accrues U.S. federal income taxes on unremitted earnings of all foreign subsidiaries. Prior to the second quarter of 2016, deferred U.S. federal income taxes had not been recorded for the undistributed earnings for Terphane Ltda. because the Company had intended to permanently reinvest these earnings. Due to concerns about the political and economic conditions in Brazil, Terphane Ltda. began making cash distributions to the Company in 2016. During the second quarter of 2016, Terphane Ltda. paid a dividend of $10.7 million to the Company. During the second quarter of 2017, the Company recognized a net tax benefit of $0.4 million associated with additional U.S. tax related to this repatriation of cash from Brazil offset by the reversal of related tax contingencies. Because of the accumulation of significant losses related to foreign currency translations at Terphane Ltda., there were no deferred tax liabilities associated with the U.S. federal income taxes and foreign withholding taxes on Terphane Ltda.’s undistributed earnings as of September 30, 2017 and December 31, 2016 . 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 Ltda.’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 to 15.25% levied on the operating profit on certain of its products. The incentives have been granted for a 10 -year period, which has a commencement date of January 1, 2015. No benefit was recognized from these tax incentives in the first nine months of 2017 or 2016 . Income taxes in 2017 included a partial reversal of a valuation allowance of less than $0.1 million related to the expected limitations on the utilization of assumed capital losses on certain investments that were recognized in prior years. Income taxes in 2016 included the partial reversal of a valuation allowance of $0.1 million related to the expected limitations on the utilization of assumed capital losses on certain investments. The Company had a valuation allowance for excess capital losses from investments and other related items of $11.2 million at September 30, 2017 . Tredegar continues to evaluate opportunities to utilize these loss carryforwards prior to their expiration at various dates in the future. As events and circumstances warrant, allowances will be reversed when it is more likely than not that future taxable income will exceed deductible amounts, thereby resulting in the realization of deferred tax assets. Tredegar and its subsidiaries file income tax returns in the U.S., various states and jurisdictions outside the U.S. With exceptions for some U.S. states and non-U.S. jurisdictions, Tredegar and its subsidiaries are no longer subject to U.S. federal, state or non-U.S. income tax examinations by tax authorities for years before 2014.

Commitments and Contingencies Disclosure [Abstract]
Contingencies	In 2011, Tredegar was notified by U.S. Customs and Border Protection (“U.S. Customs”) that certain film products exported by Terphane Ltda. 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. The Company contested the applicability of these antidumping duties to the films exported by Terphane Ltda., and it 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 Ltda. 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. In December 2014, the U.S. International Trade Commission voted to revoke the anti-dumping duty order on imported PET films from Brazil. The revocation, as a result of the vote by the U.S. International Trade Commission, was effective as of November 2013. On February 20, 2015, certain U.S. producers of PET films filed a summons with the U.S. Court of International Trade to appeal the determination by the U.S. International Trade Commission. The Court granted a motion by the plaintiffs to stay the appeal of the revocation decision pending the resolution of the scope appeal. On June 8, 2017, the U.S. Court of International Trade remanded the scope determination to Commerce for re-consideration of certain scope issues. On October 20, 2017, Commerce filed its Remand Redetermination Results with the U.S. Court of International Trade, and again found that Terphane Ltda.’s films are outside of the scope of the antidumping duty order. Commerce’s decision will now be reviewed by the U.S. Court of International Trade.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements	In May 2014, the Financial Accounting Standards Board (“FASB”) and International Accounting Standards Board (“IASB”) issued their converged standard on revenue recognition. The revised revenue standard contains principles that an entity will apply to direct the measurement of revenue and timing of when it is recognized. The core principle of the guidance is that the recognition of revenue should depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which an entity expects to be entitled in exchange for those goods and services. To achieve that core principle, an entity will utilize a principle-based five-step approach model. The converged standard also includes more robust disclosure requirements which will require entities to provide sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In March 2016, amended guidance was issued regarding clarifying the implementation guidance on principal versus agent considerations and in April 2016, clarifying guidance was issued relating to identifying performance obligations and licensing implementation. The effective date of this revised standard is for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Early application is permitted as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that annual reporting period. The converged standard can be adopted either retrospectively or through the use of a practical expedient. The Company has made substantial progress towards assessing the impact of this standard. The Company has a team in place to analyze the impact of the standard, and the related guidance issued, across all revenue streams to evaluate the impact of the new standard on revenue contracts. This includes reviewing current accounting policies and practices to identify potential differences that would result from applying the requirements under the new standard. In 2016, the Company made progress on contract reviews, which were completed and validated in the first half of 2017. The Company has also started evaluating the new disclosure requirements and expects to complete its evaluations of the impacts of the accounting and disclosure requirements on its business processes, controls and systems by the end of 2017. The Company is still evaluating the method of adoption of the standard, which will occur in the first quarter of 2018. In July 2015, the FASB issued new guidance for the measurement of inventories. Inventories within the scope of the revised guidance should be measured at the lower of cost or net realizable value. The previous guidance dictated that inventory should be measured at the lower of cost or market, with market being either replacement cost, net realizable value or net realizable value less an approximation of normal profit margin. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. Subsequent measurement is unchanged for inventories measured using LIFO or the retail inventory method. The amendments should be applied prospectively, with early adoption permitted. The Company adopted the new guidance prospectively in the first quarter of 2017, and the adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. In January 2016, the FASB issued amended guidance associated with accounting for equity investments measured at fair value. The amended guidance requires all equity investments to be measured at fair value with changes in the fair value recognized through net income (other than those accounted for under equity method of accounting or those that result in consolidation of the investee). The amended guidance also requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. In addition, the amendments in this update eliminate the requirement to disclose the fair value of financial instruments measured at amortized cost for entities that are not public business entities and the requirement to disclose the method(s) and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet for public business entities. The amended guidance is effective for fiscal years beginning after December 31, 2017, including the interim periods within those fiscal years. The amendments should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption. The amendments related to equity securities without readily determinable fair values (including disclosure requirements) should be applied prospectively to equity investments that exist as of the date of adoption of the update. Early adoption is permitted under limited, specific circumstances. The guidance is not expected to have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued a revised standard on lease accounting. Lessees will need to recognize virtually all of their leases on the balance sheet, by recording a right-of-use asset and lease liability. The revised standard requires additional analysis of the components of a transaction to determine if a right-to-use asset is embedded in the transaction that needs to be treated as a lease. Substantial additional disclosures are also required by the revised standard. The revised standard is effective for fiscal years beginning after December 31, 2018, including the interim periods within those fiscal years. The revised standard should be applied on a modified retrospective approach, with early adoption permitted. The Company is still assessing the impact of this revised standard on the Company’s consolidated financial statements. In March 2016, the FASB issued amended guidance to simplify several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statements of cash flows. The Company adopted the new guidance in the first quarter of 2017. Under the new guidance, excess tax benefits related to equity compensation were recognized in "Income taxes" in the consolidated statements of income rather than in "Common stock" in the consolidated balance sheets and were applied on a prospective basis. If these amounts had been included in the consolidated statements of income in previous years, net income would have been reduced by $0.5 million in the first nine months of 2016 (none in the third quarter of 2016) and $1.1 million for the full year 2016. Changes to the statements of cash flows related to the classification of excess tax benefits and employee taxes paid for share-based payment arrangements were implemented on a retrospective basis. In addition, the updated guidance allows the Company to make an accounting policy election related to how forfeitures will impact the recognition of stock compensation cost. Previously, entities were required to estimate forfeitures at the grant date, accounting for estimated forfeitures over the requisite service period. Under the updated guidance, the Company can choose, and the Company has elected, to account for forfeitures as they occur. The Company adopted the updated guidance in the first quarter of 2017, and the adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. In October 2016, the FASB issued guidance that requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The amendments are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, and should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings at the beginning period of adoption. Early adoption is permitted in the first interim period of an annual reporting period for which financial statements have not been issued. The Company is currently evaluating the impact of adopting this guidance on the Company’s consolidated financial statements. In January 2017, the FASB issued guidance to assist with evaluating when a set of transferred assets and activities (collectively, the "set") is a business and provides a screen to determine when such a set is not a business. Under the new guidance, when substantially all of the fair value of gross assets acquired (or disposed of) is concentrated in a single identifiable asset, or group of similar assets, the assets acquired would not represent a business. Also, to be considered a business, an acquisition would have to include an input and a substantive process that together significantly contribute to the ability to produce outputs. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017, and should be applied on a prospective basis to any transactions occurring within the period of adoption. Early adoption is permitted for interim or annual periods in which the financial statements have not been issued. The Company has not elected early adoption of this guidance and will apply the new guidance beginning in the first quarter of 2018. In January 2017, the FASB issued amended guidance that eliminates the requirement to determine the fair value of individual assets and liabilities of a reporting unit to measure goodwill impairment. Under the amendments in the new guidance, goodwill impairment testing will be performed by comparing the fair value of the reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. The new standard is effective for annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019, and should be applied on a prospective basis. Early adoption is permitted for annual or interim goodwill impairment testing performed after January 1, 2017. The Company is currently evaluating the impact of adopting this guidance on the Company’s consolidated financial statements. In March 2017, the FASB issued final guidance on the presentation of net periodic pension and postretirement benefit cost (net benefit cost). Currently, net benefit cost is reported as an employee cost within operating income. This new guidance requires the bifurcation of net periodic pension and postretirement benefit costs. Service cost will be part of operating income (and is the only piece eligible to be capitalized). All other components will be shown outside of operations. The new standard is effective for annual and interim periods in fiscal years beginning after December 15, 2017, and should be applied on a retrospective basis, except for the amendments related to capitalization of benefit cost, which should be applied on a prospective basis. Early adoption is permitted only in the first quarter of the reporting year. The Company is currently evaluating the impact of adopting this guidance on the Company’s consolidated financial statements. In August 2017, the FASB issued amended guidance on the accounting for hedging activities. The amended guidance makes more hedging strategies qualify for hedge accounting. After initial qualification, the amended guidance permits a qualitative effectiveness assessment for certain hedges instead of a quantitative test, if the company can reasonably support an expectation of effectiveness throughout the term of the hedge. The amended guidance is effective for annual and interim periods beginning after January 1, 2019, but may be adopted immediately. The adoption should be on a cumulative effect basis and applied prospectively. The Company is currently evaluating the impact of adopting this guidance on the Company’s consolidated financial statements.
