POWER OF ATTORNEY

                KNOW ALL BY THESE PRESENTS, that the undersigned hereby
constitutes and appoints each of Tony J. Steenkolk, David Rouse and Kent A.
Pflederer, signing singly, the undersigned's true and lawful attorney-in-fact
to: (i) execute for and on behalf of the undersigned, in the undersigned's
capacity as an executive officer or director of Packaging Corporation of
America, a Delaware corporation (the "Company"), statements of beneficial
ownership on Forms 3, 4 and 5 under Section 16(a) of the Securities Exchange Act
of 1934, as amended (the "Exchange Act") and the rules thereunder; (ii) do and
perform any and all acts for and on behalf of the undersigned which may be
necessary or desirable to complete and execute any such Form 3, 4 and 5 and
timely file such form with the United States Securities and Exchange Commission
and any stock exchange or similar authority; and (iii) take any other action of
any type whatsoever in connection with the foregoing which, in the opinion of
such attorney-in-fact, may be of benefit to, in the best interest of, or legally
required by, the undersigned, it being understood that the documents executed by
such attorney-in-fact on behalf of the undersigned pursuant to this Power of
Attorney shall be in such form and shall contain such terms and conditions as
such attorney-in-fact may approve in such attorney-in-fact's discretion.

                The undersigned hereby grants to each such attorney-in-fact full
power and authority to do and perform any and every act and thing whatsoever
requisite, necessary, or proper to be done in the exercise of any of the rights
and powers herein granted, as fully to all intents and purposes as the
undersigned might or could do if personally present, with full power of
substitution or revocation, hereby ratifying and confirming all that such

granted.  The undersigned acknowledges that the foregoing attorneys-in-fact, in
serving in such capacity at the request of the undersigned, are not assuming,
nor is the Company assuming, any of the undersigned's responsibilities to comply

This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4 and 5 with respect to the
undersigned's holdings of and transactions in securities issued by the Company,
unless earlier revoked by the undersigned in a signed writing delivered to the
foregoing attorneys-in-fact.  This Power of Attorney revokes all prior powers of
attorney delivered by the undersigned relating to the subject matter hereof.

IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
