<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are filing this Registration Statement to register (i)&nbsp;an additional 600,000 shares of our
common stock, par value $0.01 per share (the &#147;Common Stock&#148;), that may be acquired by Company
employees under the Packaging Corporation of America Thrift Plan for Hourly Employees (the &#147;Thrift
Plan&#148;), (ii)&nbsp;an additional 1,400,000 shares of our Common Stock that may be acquired by Company
employees under the Packaging Corporation of America Retirement Savings Plan for Salaried Employees

</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The increase in the number of shares authorized for issuance under the Equity Plan, as well as
certain other amendments to the Equity Plan that are described in our Definitive Proxy Statement
for our 2009 annual meeting of stockholders, were approved by our stockholders at our 2009 annual
meeting held on May&nbsp;27, 2009. The full text of the Equity Plan, as amended by that stockholder
approval, will be sent to employees pursuant to Rule&nbsp;428(b)(1) promulgated by the Securities and
Exchange Commission (the &#147;Commission&#148;) under the Securities Act of 1933, as amended (the
&#147;Securities Act&#148;), and is available on the Commission&#146;s website as an exhibit to our Definitive
Proxy Statement on Schedule&nbsp;14A, filed with the Commission on April&nbsp;21, 2009. The full text of the
Thrift Plan and the Savings Plan is available on the Commission&#146;s website as an exhibit to our
Registration Statement on Form S-8 (Reg. No.&nbsp;333-33176), filed with the Commission on March&nbsp;23,
2000 (the &#147;Original Registration Statement&#148;).
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We previously filed the Original Registration Statement on March&nbsp;23, 2000 covering (i)
5,800,000 shares of our Common Stock under the Thrift Plan and the Savings Plan and (ii)&nbsp;4,400,000
shares of our Common Stock authorized for issuance under the original version of the Equity Plan.
In addition, on June&nbsp;29, 2005, we filed an additional Registration Statement on Form S-8 (Reg. No.
333-126215) to register an additional 2,150,000 shares of our Common Stock pursuant to an amendment

change in the information set forth in this Registration Statement. Notwithstanding
the foregoing, any increase or decrease in the volume of securities offered (if the
total dollar value of securities offered would not exceed that which was registered)
and any deviation from the low or high end of the estimated maximum offering range
may be reflected in the form of prospectus filed with the Commission pursuant to
Rule 424(b) if, in the aggregate, the changes in volume and price represent no more

Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an
employee benefit plan&#146;s annual report pursuant to Section 15(d) of the Exchange Act) that is

permitted to directors, officers and controlling persons of the registrant pursuant to the
foregoing provisions, or otherwise, the registrant has been advised that in the opinion of
the Commission such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred or paid by a
director, officer or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in the opinion
of its counsel the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final adjudication of
such issue.

EXPLANATORY NOTE
We are filing this Registration Statement to register (i) an additional 600,000 shares of our
common stock, par value $0.01 per share (the "Common Stock"), that may be acquired by Company
employees under the Packaging Corporation of America Thrift Plan for Hourly Employees (the "Thrift
Plan"), (ii) an additional 1,400,000 shares of our Common Stock that may be acquired by Company
employees under the Packaging Corporation of America Retirement Savings Plan for Salaried Employees
(the "Savings Plan") and (iii) an additional 2,000,000 shares of our Common Stock for issuance
under the Packaging Corporation of America Amended and Restated 1999 Long-Term Equity Incentive
Plan (the "Equity Plan").
The increase in the number of shares authorized for issuance under the Equity Plan, as well as
certain other amendments to the Equity Plan that are described in our Definitive Proxy Statement
for our 2009 annual meeting of stockholders, were approved by our stockholders at our 2009 annual
meeting held on May 27, 2009. The full text of the Equity Plan, as amended by that stockholder
approval, will be sent to employees pursuant to Rule 428(b)(1) promulgated by the Securities and
Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the
"Securities Act"), and is available on the Commission's website as an exhibit to our Definitive
Proxy Statement on Schedule 14A, filed with the Commission on April 21, 2009. The full text of the
Thrift Plan and the Savings Plan is available on the Commission's website as an exhibit to our
Registration Statement on Form S-8 (Reg. No. 333-33176), filed with the Commission on March 23,
2000 (the "Original Registration Statement").
We previously filed the Original Registration Statement on March 23, 2000 covering (i)
5,800,000 shares of our Common Stock under the Thrift Plan and the Savings Plan and (ii) 4,400,000
shares of our Common Stock authorized for issuance under the original version of the Equity Plan.
In addition, on June 29, 2005, we filed an additional Registration Statement on Form S-8 (Reg. No.
333-126215) to register an additional 2,150,000 shares of our Common Stock pursuant to an amendment
and restatement of the Equity Plan that increased the number of shares authorized for issuance
under the Equity Plan, as approved by our stockholders at our 2005 annual meeting of stockholders.
Pursuant to General Instruction E to Form S-8, the contents of the Original Registration Statement,
including the periodic and current reports that we filed with the Commission after the
effectiveness of the Original Registration Statement, are incorporated herein by reference except
to the extent supplemented, amended or superseded by the information set forth herein. Any items
in the Original Registration Statement not expressly changed hereby shall be as set forth in the
Original Registration Statement.

(d) the description of the Company's common stock, par value $0.01 per share, included

Company's Registration Statement on Form S-1, initially filed with the Commission on
September 13, 1999 (Registration No. 333-86963), including exhibits, as amended, and as may

in Item 1 of the Company's Registration Statement on Form 8-A, filed pursuant to Section 12
of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), on October 15, 1999
(Registration No. 001-15399).
All documents subsequently filed by the Company pursuant to Sections 13(a), 13(c), 14 and
15(d) of the Exchange Act, prior to the filing of a post-effective amendment which indicates that
all securities offered hereby have been sold or which deregisters all securities then remaining
unsold, shall be deemed to be incorporated by reference herein and to be a part hereof from the
date of filing of such documents.
Any statement contained in a document incorporated or deemed to be incorporated by reference
herein shall be deemed to be modified or superseded for purposes of this Registration Statement to
the extent that a statement contained herein or in any other subsequently filed document which also
is or is deemed to be incorporated by reference herein modifies or supersedes such statement. Any
statement so modified or superseded shall not be deemed, except as so modified or superseded, to
constitute a part of this Registration Statement.
Item 5. Interests of Named Experts and Counsel.
Certain legal matters in connection with the issuance of the shares of Common Stock offered
hereby will be passed upon for the Company by Kent A. Pflederer, Vice President, General Counsel
and Corporate Secretary of the Company. Mr. Pflederer is the beneficial owner of 6,195 shares of
the Company's Common Stock and has options to purchase 1,250 additional shares of Common Stock of
the Company, of which 834 are exercisable within 60 days of the date of this Registration
Statement. Mr. Pflederer is eligible to participate in the Savings Plan and the Equity Plan.
Item 8. Exhibits.
See the accompanying Exhibit Index for a list of Exhibits to this Registration Statement,
which is incorporated by reference herein.
Item 9. Undertakings.
(a) The undersigned registrant hereby undertakes:
2
(1) to file, during any period in which offers or sales are being made, a
post-effective amendment to this Registration Statement:
(i) to include any prospectus required by Section 10(a)(3) of the Securities
Act;
(ii) to reflect in the prospectus any facts or events arising after the
effective date of this Registration Statement (or most recent post-effective
amendment thereof) which, individually or in the aggregate, represent a fundamental
change in the information set forth in this Registration Statement. Notwithstanding
the foregoing, any increase or decrease in the volume of securities offered (if the
total dollar value of securities offered would not exceed that which was registered)
and any deviation from the low or high end of the estimated maximum offering range
may be reflected in the form of prospectus filed with the Commission pursuant to
Rule 424(b) if, in the aggregate, the changes in volume and price represent no more
than a twenty percent change in the maximum aggregate offering price set forth in
the "Calculation of Registration Fee" table in the effective registration statement;
and
(iii) to include any material information with respect to the plan of
distribution not previously disclosed in this Registration Statement or any material
change to such information in this Registration Statement;
provided, however
, that paragraphs (a)(1)(i) and (a)(1)(ii) of this section do not apply if
the information required to be included in a post-effective amendment by those paragraphs is
contained in reports filed with or furnished to the Commission by the Company pursuant to
section 13 or section 15(d) of the Exchange Act that are incorporated by reference in this
Registration Statement;
(2) that, for the purpose of determining any liability under the Securities Act, each
such post-effective amendment shall be deemed to be a new registration statement relating to
the securities offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof; and
(3) to remove from registration by means of a post-effective amendment any of the
securities being registered which remain unsold at the termination of the offering.
(b) The undersigned registrant hereby undertakes that, for purposes of determining any
liability under the Securities Act, each filing of the Company's annual report pursuant to
Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the Exchange Act) that is
incorporated by reference in this Registration Statement shall be deemed to be a new
registration statement relating to the securities offered herein, and the offering of such
securities at that time shall be deemed to be the initial bona fide offering thereof.
(c) Insofar as indemnification for liabilities arising under the Securities Act may be
permitted to directors, officers and controlling persons of the registrant pursuant to the
foregoing provisions, or otherwise, the registrant has been advised that in the opinion of
the Commission such indemnification is against public policy as expressed in the Securities
Act and is, therefore, unenforceable. In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred or paid by a
director, officer or controlling person of the registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in the opinion
of its counsel the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final adjudication of
such issue.
