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. 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. Tredegar’s 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 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 sheet) was $39.1 million at March 31, 2015 and December 31, 2014. The fair value estimates are based upon significant unobservable (Level 3) inputs since there is no secondary market for our ownership interest. Accordingly, until the next round of financing or other significant financial transaction, value estimates will primarily be based on assumptions relating to meeting product development and commercialization milestones, corresponding cash flow projections (projections of sales, costs, expenses, capital expenditures and working capital investment) and discounting of these factors for the high degree of risk. Adjustments to the estimated fair value of the Company’s investment in kaléo will be made in the period during which changes can be quantified.
	The Company did not recognize an unrealized gain or loss on its investment in kaléo in the first three months of 2015 and 2014. In the first quarter of 2014, the weighted average cost of capital used to discount cash flow projections was decreased to reflect lower product risk after the U.S. Food and Drug Administration's approval of kaléo's naloxone auto-injector for emergency treatment of known or suspected opioid overdoses and reduced funding risk subsequent to kaléo securing new debt financing, both of which occurred in April 2014. The favorable impact of a lower weighted average cost of capital used to discount cash flow projections in the first quarter of 2014 was offset by adjustments to the amount and timing of the projected receipt of royalty and milestone payments from commercial sales of kaléo's licensed epinephrine auto-injector for treatment of allergic reactions.
	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 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 Tredegar’s interest in kaléo was 45% at March 31, 2015 and December 31, 2014. At March 31, 2015, the effect of a 500 basis point decrease in the weighted average cost of capital assumption would have increased the fair value of the interest in kaléo by approximately $7 million, and a 500 basis point increase in the weighted average cost of capital assumption would have decreased the fair value of the interest by approximately $5 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 March 31, 2015 and December 31, 2014 and condensed statement of operations for the three months ended March 31, 2015 and 2014, as reported to the Company by kaléo, are provided below:

	(a) “Expenses and other, net” includes selling, general and administrative expense, research and development expense, interest expense and other income (expense), net.
	The Company’s investment in the Harbinger Fund had a carrying value (included in “Other assets and deferred charges”) of $1.8 million at March 31, 2015 and December 31, 2014, respectively. The carrying value at March 31, 2015 reflected Tredegar’s cost basis in its investment in the Harbinger Fund, net of total withdrawal proceeds received and unrealized losses. The Company recorded unrealized losses of $0.2 million in the first three months of 2014, (none in the first three months of 2015) on its investment in the Harbinger Fund (included in “Other income (expense), net” in the consolidated statements of income) as a result of a reduction in the value of the investment that is not expected to be temporary. There were no withdrawal proceeds in the first three months of 2015 and 2014. The timing and amount of future installments of withdrawal proceeds, which commenced in August 2010, were not known as of March 31, 2015. 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.
	Tredegar has investment property in Alleghany and Bath Counties, Virginia. The carrying value in this investment property (included in “Other assets and deferred charges” on the consolidated balance sheets) was $2.6 million at March 31, 2015 and December 31, 2014.

Derivative_Financial_Instrumen

Derivative Financial Instruments	3 Months Ended
	Mar. 31, 2015
Summary of Derivative Instruments [Abstract]
Derivative Financial Instruments	The Company 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 due to specified transactions. When possible, derivative financial instruments utilized by Tredegar are designated as and qualify as cash flow hedges and are recognized in the balance sheet at fair value. A change in the fair value of derivatives that are highly effective and that are designated and qualify as cash flow hedges is recorded in other comprehensive income (loss). 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. 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 was not material to the three month periods ended March 31, 2015 and 2014.
	The fair value of derivative instruments recorded on the consolidated balance sheets is based upon Level 2 inputs within the corresponding commodity or foreign currency markets. 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, the Company 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 the margin exposure created from the fixing of future sales prices relative to volatile raw material (aluminum) costs, the Company 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 $14.0 million (13.0 million pounds of aluminum) at March 31, 2015 and $8.6 million (7.8 million pounds of aluminum) at December 31, 2014.
	The table below summarizes the location and gross amounts of aluminum futures contract fair values in the consolidated balance sheets as of March 31, 2015 and December 31, 2014:
		31-Mar-15						31-Dec-14
	(In Thousands)	Balance Sheet		Fair				Balance Sheet	Fair
		Account		Value				Account	Value
	Derivatives Designated as Hedging Instruments
	Asset derivatives:	Accrued expenses		$	2			Accrued expenses	$	82
	Aluminum futures contracts
	Liability derivatives:	Accrued expenses		$	(1,284	)		Accrued expenses	$	(318	)
	Aluminum futures contracts
	Derivatives Not Designated as Hedging Instruments
	Asset derivatives:	Accrued expenses		$	28			Accrued expenses	$	7
	Aluminum futures contracts

	Aluminum futures contracts
	Net asset (liability)			$	(1,282	)			$	(236	)
	In the event that the counterparty to an aluminum fixed-price forward sales contract chooses to not 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 offsetting asset and liability positions for derivatives not designated as hedging instruments (none at March 31, 2015) are associated with the unwinding of aluminum futures contracts that relate to such cancellations.
	Film Products utilized 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. The Company used fixed-rate Euro forward contracts with various settlement dates to hedge exchange rate exposure on these obligations. The Company did not have any fixed-rate forward contracts with outstanding notional amounts as of March 31, 2015 and December 31, 2014.
	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 our foreign currency futures and zero-cost collar contracts are major financial institutions.
	The effect on net income and other comprehensive income (loss) of derivative instruments classified as cash flow hedges and described in the previous paragraphs for the three month periods ended March 31, 2015 and 2014 is summarized in the table below:
	(In Thousands)	Cash Flow Derivative Hedges
		Aluminum Futures							Foreign Currency
		Contracts							Forwards
		Three Months Ended March 31,
		2015				2014			2015			2014
	Amount of pre-tax gain (loss) recognized in other comprehensive income	$	(1,094	)		$	264		$	—		$	8
	Location of gain (loss) reclassified from accumulated other comprehensive income into net income (effective portion)	Cost of				Cost of			Cost of
		sales				sales			sales
	Amount of pre-tax gain (loss) reclassified from accumulated other comprehensive income to net income (effective portion)	$	(48	)		$	(37	)	$	15		$	—
	As of March 31, 2015, the Company expects $0.8 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 month periods ended March 31, 2015 and 2014, net gains or losses realized on previously unrealized net gains or losses from hedges that had been discontinued were not significant.

Compensation and Retirement Disclosure [Abstract]
Pension And Other Post-Retirement Benefits	The Company sponsors 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 plan participants was frozen as of December 31, 2007. Beginning in the first quarter of 2014, with the exception of plan participants at two of Tredegar’s U.S. manufacturing facilities, the plan no longer accrued benefits associated with crediting employees for service, thereby freezing future benefits under the plan.
	The components of net periodic benefit cost for our pension and other post-retirement benefit programs reflected in consolidated results are shown below:
		Pension Benefits						Other Post-Retirement Benefits
		Three Months Ended March 31,						Three Months Ended March 31,

	Curtailment charge	—			81			—			—
	Net periodic benefit cost	$	3,073		$	2,222		$	56		$	29
	Pension and other post-retirement liabilities for continuing operations were $103.8 million and $104.8 million at March 31, 2015 and December 31, 2014, respectively ($0.6 million included in “Accrued expenses” at March 31, 2015 and December 31, 2014, with the remainder included in “Other noncurrent liabilities” in the consolidated balance sheets) . The Company’s required contributions are expected to be approximately $2.4 million in 2015. 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, 2014, or $0.3 million.

Income Tax Disclosure [Abstract]
Income Taxes	The effective tax rate for income from continuing operations in the first three months of 2015 was 32.6% compared to 35.2% in the first three months of 2014. The significant differences between the U.S. federal statutory rate and the effective income tax rate for continuing operations for the three months ended March 31, 2015 and 2014 are as follows:
		Percent of Income
		Before Income Taxes
	Three Months Ended March 31,	2015		2014

	Effective income tax rate for income from continuing operations	32.6		35.2
	In 2014, the Brazilian federal statutory income tax rate was a composite of 34.0% (25.0% of income tax and 9.0% of social contribution on income). Terphane Holdings, LLC’s (“Terphane”) 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 produced a current effective tax rate of 15.25% for Terphane Ltda. (6.25% of income tax and 9.0% social contribution on income). These incentives expired at the end of 2014. The Company anticipates that it will qualify for additional incentives that will extend beyond 2014, but the future benefit will not be recorded until the amount and extent of these incentives are more fully known. The benefit from tax incentives was $0.3 million ($0.01 per share) in the first three months of 2014.
	In connection with its capacity expansion project in Brazil, the Company has paid certain social taxes associated with the purchase of machinery and equipment and construction of buildings and other long-term assets. Payments of these taxes in Brazil were included in “Net cash used in investing activities” given the nature of the underlying use of cash (e.g. the purchase of property, plant and equipment). The Company can recover tax credits associated with the purchase of machinery and equipment at different points over a period up to 24 months. Once the machinery and equipment was placed into service, the Company started applying these tax credits against various other taxes due in Brazil, with their recovery being reflected as cash received from investing activities, consistent with the classification of the original payments.
	Income taxes from continuing operations in 2015 included a partial reversal of a valuation allowance of $0.2 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 2014 included the recognition of an additional valuation allowance of $40,000 related to the expected limitations on the utilization of assumed capital losses on certain investments. The Company has a valuation allowance for excess capital losses from investments and other related items of $11.1 million at March 31, 2015. 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 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.

Warrants and Rights Note Disclosure [Abstract]
Shareholder Rights Agreement	Pursuant to the Second Amended and Restated Rights Agreement (the “Rights Agreement”), dated as of November 18, 2013, with Computershare Trust Company, N.A., as Rights Agent, one purchase right (a “Right”) was attached to each outstanding share of the Company’s Common Stock.  Each Right entitled 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”). Unless otherwise noted in the Rights Agreement, the Rights would have become exercisable, if not earlier redeemed, only if a person or group (i) acquires beneficial ownership of 20% or more of the outstanding shares of 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”).
	On February 19, 2014, the Company’s Board of Directors authorized the termination of the Rights Agreement and the redemption of all of the outstanding Rights, at a redemption price of $.01 per Right to be paid in cash to shareholders of record as of the close of business on March 3, 2014. The corresponding redemption payment of $0.3 million was made in the first quarter of 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 Holdings, LLC (“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.  The Company contested the applicability of these antidumping duties to the films exported by Terphane, 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 can establish to the satisfaction of U.S. Customs that the performance enhancing layer on those films is greater than 0.00001 inches thick.  The films at issue are manufactured to specifications that exceed that threshold.  On February 6, 2013, certain U.S. producers of PET film filed a summons with the U.S. Court of International Trade to appeal the scope ruling from Commerce.  If U.S. Customs ultimately were to require the collection of anti-dumping duties because Commerce’s scope ruling was overturned on appeal, or otherwise, indemnifications for related liabilities are specifically provided for under the Purchase Agreement. In December 2014, the U.S. International Trade Commission voted to revoke the anti-dumping duty order on imported PET films from Brazil. The revocation, as a result of the vote by the International Trade Commission, was effective as of November 2013. On February 20, 2015, certain U.S. producers of PET Film filed a summons with the U.S. Court of International Trade to appeal the determination by the U.S. International Trade Commission.

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. The amendments in this revised standard are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early adoption is not permitted. The converged standard can be adopted either retrospectively or through the use of a practical expedient. The Company is still assessing the impact of this new guidance.
	In June 2014, the FASB issued a new standard to eliminate the concept of development stage entities and all related specified presentation and reporting requirements under U.S. GAAP. In addition, the amended standard eliminated the scope exception for development stage entities when evaluating the sufficiency of equity at risk for a variable interest entity (“VIE”), thereby changing consolidation conclusions in some situations. Except for the elimination of the scope exception for development stage entities when evaluating the sufficiency of equity at risk for a VIE, the revised guidance is effective for annual reporting periods beginning after December 15, 2014, including interim periods within that reporting period. The amendments to the consolidation guidance are effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. The new standard is not expected to impact the Company.
	In April 2015, the FASB issued new guidance requiring that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct reduction from the carrying amount of that corresponding debt liability, consistent with debt discounts, rather than as a deferred charge (e.g. an asset). The new guidance will be effective for annual reporting periods beginning after December 15, 2015, including interim periods within that reporting period. The guidance requires that all prior period balance sheets be adjusted retrospectively, and early adoption is permitted. The Company expects to adopt the guidance by the first quarter of 2016. Deferred debt issuance costs associated with the Company’s Credit Agreement were $1.1 million (included in “Other assets and deferred charges” in the consolidated balance sheet) at March 31, 2015 and December 31, 2014.
