Summary Of Accounting Policies [Abstract]  
Basis Of Consolidation

Basis of Consolidation

The accompanying condensed consolidated financial statements of PCA include all majority-owned subsidiaries. All intercompany transactions have been eliminated. The Company has one joint venture that is accounted for under the equity method.
Use Of Estimates

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts in the financial statements and the accompanying notes. Actual results could differ from those estimates.
Revenue Recognition

Revenue Recognition

The Company recognizes revenue as title to the products is transferred to customers. Shipping and handling billings to a customer are included in net sales. Shipping and handling costs are included in cost of sales. In addition, the Company offers volume rebates to certain of its customers. The total cost of these programs is estimated and accrued as a reduction to net sales at the time of the respective sale.

Segment Information
