Basis Of Presentation [Abstract]
Basis Of Presentation	In the opinion of management, the accompanying condensed 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 condensed consolidated financial position as of June 30, 2022, the condensed consolidated results of operations for the three and six months ended June 30, 2022 and 2021, the condensed consolidated cash flows for the six months ended June 30, 2022 and 2021, and the condensed consolidated changes in shareholders’ equity for the six months ended June 30, 2022 and 2021, in accordance with U.S. generally accepted accounting principles (“GAAP”). All such adjustments, unless otherwise detailed in the notes to the condensed consolidated 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 second quarter for 2022 and 2021 for this segment references 13-week periods ended June 26, 2022 and June 27, 2021. 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 Company may fund or receive cash from the Aluminum Extrusions segment based on Aluminum Extrusion’s cash flows from operations during the intervening period from Aluminum Extrusion’s fiscal quarter end and the Company’s fiscal quarter end. There was no intercompany funding with Aluminum Extrusions between June 26, 2022 and June 30, 2022. The financial position data as of December 31, 2021 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, 2021 (“2021 Form 10-K”) but does not include all disclosures required by GAAP. These financial statements should be read in conjunction with the consolidated financial statements and related notes included in the 2021 Form 10-K. The results of operations for the three and six months ended June 30, 2022, are not necessarily indicative of the results to be expected for the full year. Accounting Standards Adopted . In March 2020, the FASB issued ASU 2020-04, which provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate or by another reference rate expected to be discontinued because of reference rate reform. The guidance was effective beginning March 12, 2020 and can be applied prospectively through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, which clarified the scope and application of the original guidance. In the second quarter of 2022, the Company adopted ASU 2020-04, which did not have a material impact on the Company’s consolidated financial statements.

Retirement Benefits [Abstract]
Pension And Other Post-Retirement Benefits	Tredegar sponsors a noncontributory defined benefit (pension) plan covering certain current and former U.S. employees. As of January 31, 2018, the plan no longer accrued benefits associated with crediting employees for service, thereby freezing all future benefits under the plan. On February 10, 2022, Tredegar announced the initiation of a process to terminate and settle its frozen defined benefit pension plan, which could take up to 24 months to complete. In connection therewith, on February 9, 2022, the Company contributed $50 million to the pension plan (the “Special Contribution”). The Company estimates that, with the Special Contribution, there will be no required minimum contributions to the pension plan until final settlement. Tredegar also has a non-qualified supplemental pension plan covering certain employees. Effective December 31, 2005, further participation in this plan was terminated and benefit accruals for existing participants were frozen. Pension expense recognized for this plan was immaterial in the second quarter of 2022 and 2021, respectively. This information has been included in the pension benefit table below. The components of net periodic benefit cost for the pension and other postretirement benefit programs reflected in the condensed consolidated statements of income for the three and six months ended June 30, 2022 and 2021, are shown below: Pension Benefits Other Post-Retirement Benefits Three Months Ended June 30, Three Months Ended June 30, (In thousands) 2022 2021 2022 2021 Service cost $ — $ — $ 5 $ 8 Interest cost 2,225 2,102 51 51 Expected return on plan assets (2,043) (2,863) — — Amortization of prior service costs, (gains) losses and net transition asset 3,302 4,266 (34) (24) Net periodic benefit cost $ 3,484 $ 3,505 $ 22 $ 35 Pension Benefits Other Post-Retirement Benefits Six Months Ended June 30, Six Months Ended June 30, (In thousands) 2022 2021 2022 2021 Service cost $ — $ — $ 10 $ 17 Interest cost 4,450 4,204 102 101 Expected return on plan assets (4,098) (5,725) — — Amortization of prior service costs, (gains) losses and net transition asset 6,586 8,531 (68) (48) Net periodic benefit cost $ 6,938 $ 7,010 $ 44 $ 70 Pension and other postretirement liabilities were $29.1 million and $78.9 million at June 30, 2022 and December 31, 2021, respectively ($0.7 million included in “Accrued expenses” at June 30, 2022 and December 31, 2021, respectively, with the remainder included in “Pension and other postretirement benefit obligations, net” in the condensed consolidated balance sheets). Tredegar funds its other postretirement benefits on a claims-made basis; for 2022, the Company anticipates the amount will be consistent with amounts paid for the year ended December 31, 2021, or approximately $0.5 million.

In May 2021, the Brazil Supreme Court ruled in a leading case related to the amount of Brazilian value-added tax to exclude from the calculation of unemployment/social security insurance non-income taxes ("PIS/COFINS"). As a result, in the second quarter of 2021, the Company recorded a pre-tax gain of $8.5 million for certain excess PIS/COFINS paid from 2003 to 2021, plus applicable interest, which the Company applied to required Brazilian federal tax payments during 2021.

Derivative Financial Instrument

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 exposure from currency volatility that exists as part of ongoing business operations in Flexible Packaging Films. These derivative financial instruments are designated as and qualify as cash flow hedges and are recognized in the condensed consolidated balance sheet at fair value. 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 have durations generally no longer than 24 months. The notional amount of aluminum futures contracts that hedged future purchases of aluminum to meet fixed-price forward sales contract obligations was $32.7 million (19.1 million pounds of aluminum) at June 30, 2022 and $22.1 million (14.9 million pounds of aluminum) at December 31, 2021. The table below summarizes the location and gross amounts of aluminum futures contract fair values (Level 2) in the condensed consolidated balance sheets as of June 30, 2022 and December 31, 2021: June 30, 2022 December 31, 2021 (In thousands) Balance Sheet Fair Balance Sheet Fair Derivatives Designated as Hedging Instruments Asset derivatives: Aluminum futures contracts Prepaid expenses and other $ 153 Prepaid expenses and other $ 2,085 Liability derivatives: Aluminum futures contracts Accrued expenses (1,893) Accrued expenses (119) Aluminum futures contracts Other non-current liabilities (1,332) Other non-current liabilities — Net asset (liability) $ (3,072) $ 1,966 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. The Company estimates that the net mismatch translation exposure for the Flexible Packaging Film's business unit in Brazil (“Terphane Ltda.”) of its sales and raw materials quoted or priced in U.S. Dollars and its variable conversion, fixed conversion and sales, general and administrative costs (before depreciation and amortization) quoted or priced in Brazilian Real ("R$") is annual net costs of R$150 million for the full year of 2022. Terphane Ltda. has the following outstanding foreign exchange average forward rate contracts to purchase Brazilian Real and sell U.S. Dollars: USD Notional Amount (000s) Average Forward Rate Contracted on USD/BRL R$ Equivalent Amount (000s) Applicable Month Estimated % of Terphane Ltda.

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 condensed consolidated statements of income. The table below summarizes the location and gross amounts of foreign currency forward contract fair values (Level 2) in the condensed consolidated balance sheets as of June 30, 2022 and December 31, 2021: June 30, 2022 December 31, 2021 (In thousands) Balance Sheet Fair Balance Sheet Fair Derivatives Designated as Hedging Instruments Asset derivatives: Foreign currency forward contracts Prepaid expenses and other $ 628 Prepaid expenses and other $ — Foreign currency forward contracts Other assets 41 Other assets — Liability derivatives: Foreign currency forward contracts Accrued expenses (132) Accrued expenses (1,255) Foreign currency forward contracts Other non-current liabilities (234) Other non-current liabilities — Net asset (liability) $ 303 $ (1,255) These derivative contracts involve elements of market risk that are not reflected on the condensed 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 pre-tax 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 six month periods ended June 30, 2022 and 2021 is summarized in the table below: Cash Flow Derivative Hedges Three Months Ended June 30, Aluminum Futures Contracts Foreign Currency Forwards (In thousands) 2022 2021 2022 2021 Amount of pre-tax gain (loss) recognized in other comprehensive income (loss) $ (9,923) $ 2,195 $ — $ (1,758) $ — $ 1,061 Location of gain (loss) reclassified from accumulated other comprehensive income (loss) into net income (effective portion) Cost of goods sold Cost of goods sold Cost of goods sold Selling, general & admin Cost of goods sold Selling, general & admin Amount of pre-tax gain (loss) reclassified from accumulated other comprehensive income (loss) to net income (effective portion) $ 293 $ 1,372 $ 15 $ 532 $ 16 $ (147) Six Months Ended June 30, Aluminum Futures Contracts Foreign Currency Forwards 2022 2021 2022 2021 Amount of pre-tax gain (loss) recognized in other comprehensive income (loss) $ (3,741) $ 3,710 $ — $ 2,063 $ — $ (222) Location of gain (loss) reclassified from accumulated other comprehensive income (loss) into net income (effective portion) Cost of goods sold Cost of goods sold Cost of goods sold Selling, general & admin Cost of goods sold Selling, general & admin Amount of pre-tax gain (loss) reclassified from accumulated other comprehensive income (loss) to net income (effective portion) $ 1,298 $ 2,012 $ 30 $ 669 $ 33 $ (149) As of June 30, 2022, the Company expects $1.0 million of unrealized after-tax losses on aluminum and foreign currency derivative instruments reported in accumulated other comprehensive income (loss) to be reclassified to earnings within the next 12 months. For the three and six month periods ended June 30, 2022 and 2021, net gains or losses realized, from previously unrealized net gains or losses on hedges that had been discontinued, were not material.

Income Tax Disclosure [Abstract]
Income Taxes	Tredegar recorded tax expense of $6.3 million on pre-tax income from continuing operations of $37.6 million in the first six months of 2022. Therefore, the effective tax rate in the first six months of 2022 was 16.9%, compared to 22.5% in the first six months of 2021. The decrease in the effective tax rate for continuing operations is primarily due to a discrete benefit recorded in the first quarter of 2022 resulting from the implementation of new U.S. tax regulations associated with foreign tax credits published by the U.S. Treasury and Internal Revenue Service on January 4, 2022. These regulations overhaul various components of the foreign tax credit regime including the determination of creditable foreign taxes and limit the amount of foreign taxes that are creditable against U.S. income taxes. As the result of these regulations, future Brazilian income tax will be deductible, but not creditable, in the U.S. The accounting rules require a reduction of the U.S. deferred tax liability previously established related to anticipated future income from Brazil. The tax effect of the reduction of the U.S. deferred tax liability resulted in the discrete tax benefit described above. This one-time discrete benefit is expected to reduce the effective tax rate for the remainder of 2022, which will be offset by an expected increase to the effective tax rate as the result of Brazilian income tax no longer being creditable in the U.S. for the foreseeable future. Total deferred tax assets declined during the second quarter of 2022 compared to December 31, 2021 primarily due to changes in other comprehensive income and the projected utilization of foreign tax credits partially offset by the change in the deferred tax liability discussed above. Tredegar accrues U.S. federal income taxes on unremitted earnings of foreign subsidiaries where required. However, due to changes in the taxation of dividends under the U.S. Tax Cuts and Jobs Act of 2017, Tredegar will only record U.S. federal income taxes on unremitted earnings of its foreign subsidiaries where Tredegar cannot take steps to eliminate any potential tax on future distributions from its foreign subsidiaries. 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

Segment Reporting [Abstract]
Segment Reporting	The Company’s business segments are Aluminum Extrusions, PE Films, and Flexible Packaging Films. Information by business segment is reported below. There are no accounting transactions between segments and no allocations to segments. The Company’s reportable segments are based on its method of internal reporting, which is generally segregated by differences in products. Accounting standards for presentation of segments require an approach based on the way the Company organizes the segments for making operating decisions and how the chief operating decision maker (“CODM”) assesses performance. EBITDA from ongoing operations is the key profitability measure used by the CODM (Tredegar’s President and Chief Executive Officer) for purposes of assessing financial performance. The Company uses sales less freight (“net sales”) from continuing operations as its measure of revenues from external customers at the segment level. This measure is separately included in the financial information regularly provided to the CODM. The following table presents net sales and EBITDA from ongoing operations by segment for the three and six months ended June 30, 2022 and 2021: Three Months Ended June 30, Six Months Ended June 30, (In thousands) 2022 2021 2022 2021 Net Sales Aluminum Extrusions $ 190,308 $ 139,281 $ 348,417 $ 257,405 PE Films 31,424 31,430 62,555 59,384 Flexible Packaging Films 41,595 33,374 80,839 65,895 Total net sales 263,327 204,085 491,811 382,684 Add back freight 11,036 7,044 19,118 13,267 Sales as shown in the condensed consolidated statements of income $ 274,363 $ 211,129 $ 510,929 $ 395,951 EBITDA from Ongoing Operations Aluminum Extrusions: Ongoing operations: EBITDA $ 21,895 $ 19,723 $ 45,814 $ 33,024 Depreciation & amortization (4,169) (4,032) (8,430) (8,162) EBIT 17,726 15,691 37,384 24,862 Plant shutdowns, asset impairments, restructurings and other 16 (246) (89) (63) PE Films: Ongoing operations: EBITDA 7,065 9,001 14,112 16,213 Depreciation & amortization (1,559) (1,671) (3,154) (3,090) EBIT 5,506 7,330 10,958 13,123 Plant shutdowns, asset impairments, restructurings and other (50) (151) (153) (275) Flexible Packaging Films: Ongoing operations: EBITDA 7,631 8,277 12,665 17,901 Depreciation & amortization (583) (506) (1,132) (972) EBIT 7,048 7,771 11,533 16,929 Plant shutdowns, asset impairments, restructurings and other (37) 8,452 (80) 8,414 Total 30,209 38,847 59,553 62,990 Interest income 3 25 32 32 Interest expense 1,234 891 2,020 1,713 Gain on investment in kaléo 1,406 200 1,406 918 Stock option-based compensation costs 251 675 882 1,144 Corporate expenses, net 9,789 11,055 20,510 21,917 Income (loss) from continuing operations before income taxes 20,344 26,451 37,579 39,166 Income tax expense (benefit) 5,556 5,723 6,334 8,820 Income (loss) from continuing operations 14,788 20,728 31,245 30,346 Income (loss) from discontinued operations, net of tax 81 508 47 (79) Net income (loss) $ 14,869 $ 21,236 $ 31,292 $ 30,267 The following table presents identifiable assets by segment at June 30, 2022 and December 31, 2021: (In thousands) June 30, 2022 December 31, 2021 Aluminum Extrusions $ 318,534 $ 280,521 PE Films 115,797 113,613 Flexible Packaging Films 92,060 75,269 Subtotal 526,391 469,403 General corporate 17,810 23,482 Cash and cash equivalents 27,462 30,521 Discontinued operations 151 178 Total $ 571,814 $ 523,584 The following tables disaggregate the Company’s revenue by geographic area and product group for the three and six months ended June 30, 2022 and 2021: Net Sales by Geographic Area (a) Three Months Ended June 30, Six Months Ended June 30, (In thousands) 2022 2021 2022 2021 United States $ 213,955 $ 156,719 $ 396,092 $ 289,616 Exports from the United States to: Asia 14,680 17,158 27,145 30,520 Latin America 1,245 1,358 2,686 2,460 Canada 4,173 4,604 8,366 10,038 Europe 1,085 1,025 2,448 1,980 Operations outside the United States: Brazil 28,189 23,221 55,074 48,070 Total $ 263,327 $ 204,085 $ 491,811 $ 382,684 (a) Export sales relate entirely to PE Films.

Investments, Debt and Equity Securities [Abstract]
Investments and Other Noncurrent Assets	In August 2007 and December 2008, the Company made an aggregate investment of $7.5 million in kaleo, Inc. (“kaléo”), a privately held specialty pharmaceutical company dedicated to building innovative solutions for serious and life-threatening medical conditions. Tredegar historically accounted for its investment in kaléo under the fair value option. At the time of the initial investment, the Company elected the fair value option of accounting since its investment objectives were similar to those of venture capitalists, which typically do not have controlling financial interests. kaléo’s stock is not publicly traded. In the first six months ended June 30, 2021, a pre-tax gain of $0.9 million was recognized on the Company’s investment in kaléo, which included a $0.3 million dividend received from kaléo. On December 27, 2021, the Company completed the sale of its investment interests in kaléo (Series A-3 Preferred Stock, Series B Preferred Stock and common stock) and received closing cash proceeds of $47.1 million. Subsequently, in May 2022, additional cash consideration of $1.4 million was received related to customary post-closing adjustments, which is reported in “Other income (expense), net” in the condensed consolidated statements of income.
