Adjustment to Non-PEO NEO Compensation Footnote [Text Block] | (5) The dollar amounts reported in column (f) represent the average of the amounts reported in the “Total” column of the Summary Compensation Table for the Company’s executive officers who were NEOs in the applicable year, as a group (excluding Messrs. Coker and Tiede, who served as Chief Executive Officers). The names of each of the named ​ executive officers included for purposes of calculating the average amounts reported in each applicable year are as follows: (i) for 2022, Messrs. Dillard, Fuller, Florence, Harrell and Ms. Albrecht; (ii) for 2021, Messrs. Fuller, Florence, Tomaszewski and Ms. Albrecht; and (iii) for 2020, Messrs. Fuller, Florence, Harrell and Ms. Albrecht. (6) The dollar amounts reported in column (e) represent the average amount of “compensation actually paid” to the executive officers who were NEOs in the applicable year, as a group (excluding Messrs. Coker and Tiede), as computed in accordance with Item 402(v) of Regulation S-K. The dollar amounts do not reflect the actual average amount of compensation earned by or paid to the NEOs as a group (excluding Messrs. Coker and Tiede) during the applicable year. In accordance with the requirements of Item 402(v) of Regulation S-K, the following adjustments were made to average total compensation for the NEOs as a group (excluding Messrs. Coker and Tiede) for each year to determine the compensation actually paid, using the same methodology described above in Note 3: ​

Compensation Actually Paid vs. Total Shareholder Return [Text Block] | Compensation Actually Paid versus Cumulative TSR As shown in the graph below, the CEO’s compensation actually paid (CAP) and the other NEOs’ average (CAP) amounts align with the Company’s cumulative TSR over the three years presented in the table. The relative alignment of compensation actually paid with the Company’s cumulative TSR over the period presented is because a significant portion of the compensation actually paid to Mr. Coker and to the other NEOs is comprised of equity awards. As described in more detail in the section “Executive Compensation—Compensation Discussion and Analysis,” the Company targets approximately 71% of Mr. Coker’s and 54% of the other NEO’s total target compensation awarded to be comprised of equity awards, including restricted stock units, and performance-based restricted stock units. The CAP for Mr. Tiede, our former CEO, who retired in February 2020, has been excluded from this graph. |  |
Compensation Actually Paid vs. Net Income [Text Block] | Compensation Actually Paid versus Net Income As shown in the graph below, the amount of compensation actually paid to Mr. Coker and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Messrs. Coker and Tiede) is generally aligned with the Company’s net income in the years 2020 and 2022. The Net Loss in 2021 is largely attributable to pension settlement charges of $423.5 million being recognized in 2021. While the Company does not use net income as a performance measure in the overall executive compensation program, the measure of net income is correlated with the measure of Base EBITDA, which the Company uses when setting goals for the Company’s Performance-based Annual Cash Incentive program. As described in more detail in the section “Executive Compensation—Compensation Discussion and Analysis,” the Company targets that approximately 16% and 20% of the value of total compensation awarded to Mr. Coker and the other NEOs, respectively, consists of amounts determined under the Company Performance-based Annual Cash Incentive program. The decrease in Net Income in 2021 was primarily driven by a Pension Settlement of $550.7 million dollars. The CAP for Mr. Tiede, our former CEO, who retired in February 2020, has been excluded from this graph. |  |
Compensation Actually Paid vs. Company Selected Measure [Text Block] | Compensation Actually Paid versus Base EBITDA As shown in the graph below, the amount of compensation actually paid to Mr. Coker and the average amount of compensation actually paid to the Company’s NEOs as a group (excluding Messrs. Coker and Tiede) is generally aligned with the Company’s Base EBITDA over the three years presented in the table. As described above, Base EBITDA is defined as Base Operating Profit, plus Depreciation and Amortization, plus budgeted EBITDA related to divestitures in a given year. Information on how Base Operating Profit is calculated can be found in the section “Executive Compensation—Compensation Discussion and Analysis” above and in Appendix 1. While the Company uses numerous financial performance measures for the purpose of evaluating performance for the Company’s compensation programs, the Company has determined that Base EBITDA is the financial performance measure that, in the Company’s assessment, represents the most important performance measure (that is not otherwise required to be disclosed in the table) used by the Company to link compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to Company performance is defined as net income plus non-cash interest expense, depreciation and amortization, interest and other income, income tax provision, loss (gain) on the extinguishment of debts, stock-based compensation expense and restructuring or other unusual charges. As described in more detail in the section “Executive Compensation—Compensation Discussion and Analysis,” the Company targets that approximately 16% and 20% of the value of total compensation awarded to Mr. Coker and the other NEOs, respectively, consists of amounts determined under the Company Performance-based Annual Cash Incentive program. The decrease in Base EBITDA in 2021 was primarily driven by the divestiture of the Display and Packaging business. |  |
Total Shareholder Return Vs Peer Group [Text Block] | Cumulative TSR of the Company versus the Peer Group As shown in the graph below, the Company’s cumulative TSR over the three-year period presented in the table was 8.05%, while the cumulative TSR of the peer group presented for this purpose, the Dow Jones Container and Packaging Index, was 10.26% over the three years presented in the table. For more information regarding the Company’s performance and the companies that the Compensation Committee considers when determining compensation, refer to “Executive Compensation—Compensation Discussion and Analysis.” |  |
Tabular List [Table Text Block] | Financial Performance Measures As described in greater detail in “Executive Compensation—Compensation Discussion and Analysis,” the Company’s executive compensation program reflects a variable pay-for-performance philosophy. The metrics that the Company uses for both our long-term and short-term incentive awards are selected based on an objective of incentivizing our NEOs to increase shareholder value. The most important financial performance measures used by the Company to link executive compensation actually paid to the Company’s NEOs, for the most recently completed fiscal year, to the Company’s performance are as follows: • Base EBITDA ​ • Base EPS ​ • Return on Invested Capital (ROIC) ​ • Operating Cash Flow |  |
Total Shareholder Return Amount | $ 108.05 | 99.75 | 99.24
Peer Group Total Shareholder Return Amount | 110.26 | 142.14 | 128.66
Net Income (Loss) | $ 466,980,000 | $ (82,711,000) | $ 207,241,000

Additional 402(v) Disclosure [Text Block] | Summary Compensation Table versus Compensation Actually Paid The graphs below provide a comparison of the compensation reported in the Summary Compensation Table versus compensation actually paid to Mr. Coker and average compensation actually paid to the Company’s other NEOs. The compensation for Mr. Tiede, our former CEO who retired in February 2020, has been excluded from this graph. We feel that it is important to provide a graphic comparison that shows the different components that factor into the calculations. The compensation reported in the Summary Compensation Table is based on the grant date value of equity awards granted during the applicable year and the compensation actually paid as reported in the Pay for Performance tables is based on the fair value of equity awards granted during the applicable year and valued at year end, plus the change in value of previously granted as of year-end (or the vesting date, if earlier). In essence, the compensation actually paid reflects the fair value of all or portions of 4 years’ worth of equity awards as of specified valuation dates, while the compensation reported in Summary Compensation Table is based solely on the equity awards granted in 2022, all of which are valued based on the fair value as determined on the date of grant. |  |
