             Report of Independent Registered Public Accounting Firm

To the Pactiv Corporation Benefits Committee:

We have audited the accompanying statements of assets available for benefits of
the Pactiv Hourly 401(k) Savings and Investment Plan as of December 31, 2004 and
2003, and the related statements of changes in assets available for benefits for
the years then ended. These financial statements are the responsibility of the
Plan's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. We were not engaged to perform an
audit of the Plan's internal control over financial reporting. Our audits
included consideration of internal control over financial reporting as a basis
for designing audit procedures that are appropriate in the circumstances, but
not for the purpose of expressing an opinion on the effectiveness of the Plan's
internal control over financial reporting. Accordingly, we express no such
opinion. An audit includes examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements, assessing the accounting
principles used and significant estimates made by management, and evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.


In our opinion, the financial statements referred to above present fairly, in
all material respects, the assets available for benefits of the Plan at December
31, 2004 and 2003, and the changes in assets available for benefits for the
years then ended, in conformity with U.S. generally accepted accounting
principles.

Our audits were performed for the purpose of forming an opinion on the basic
financial statements taken as a whole. The accompanying supplemental schedule of
assets (held at end of year) as of December 31, 2004, is presented for purposes
of additional analysis and is not a required part of the basic financial
statements but is supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. This supplemental schedule is the
responsibility of the Plan's management. The supplemental schedule has been
subjected to the auditing procedures applied in our audits of the basic
financial statements and, in our opinion, is fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

                          Notes to Financial Statements

                           December 31, 2004 and 2003

1. DESCRIPTION OF PLAN

The following description of the Pactiv Hourly 401(k) Savings and Investment
Plan (the Plan), provides only general information. Participants should refer to
the Plan document for a more complete description of the Plan's provisions.

GENERAL

The Plan is a defined contribution plan subject to the provisions of the
Employee Retirement Income Security Act of 1974, as amended (ERISA). Pactiv
Corporation (Company) is the sponsor of the Plan.


ELIGIBILITY AND CONTRIBUTIONS

Depending on their location, employees are eligible to enter the Plan on either
the first day of the month following the completion of one full calendar month
of service or the first day of the month following the first anniversary of
his/her hire date. Employees are eligible for the Company matching contribution
after completing one year of service (or eligible/not eligible as specified in a
covered group's special appendix to the Plan).

Participants may make contributions by payroll deduction of 1% up to 25%(16%
prior to January 2, 2004) of compensation (or such percentage of compensation as
may be specified in a covered group's special appendix to the Plan), as defined
in the Plan, with such contributions limited to $13,000 in 2004 and $12,000 in
2003 (or $16,000 in 2004 and $14,000 in 2003 for participants who are eligible
to make catch-up contributions). Generally, the Company makes matching
contributions equal to 100% of participants' contributions up to 3% of eligible
compensation deferred (or such other percentage as may be specified in a covered
group's special appendix to the Plan).

Company matching contributions can be made in the form of Pactiv Corporation
common stock or cash. In 2004 and 2003, $3,394,451 and 3,131,501, respectively
of Company matching contributions were made in shares of company stock.

Prior to January 29, 2002, Company matching contributions made in the form of
Pactiv Corporation common stock could not be sold until participants reached age
55 or terminated employment and requested a total distribution. Effective
January 29, 2002 for hourly nonunion employees and April 1, 2002 for union
employees, participants are permitted to sell Pactiv Corporation common stock
attributable to Company matching contributions and transfer related amounts into
other investment options offered by the Plan.

Subject to the special appendix to the Plan, select covered groups are entitled
to receive profit-sharing contributions. Profit-sharing contributions were
$56,359 and $61,613 for 2004 and 2002, respectively.

INVESTMENT OPTIONS

Participants have the right upon enrollment to select the funds offered by the
Plan in which the balance in their accounts will be invested.

VESTING

Participants are immediately vested in their own deferrals and actual earnings
thereon.

Vesting of Company matching and profit sharing contributions is detailed in each
covered group's special appendix to the Plan.

Upon attainment of age 65 or termination of employment with the Company due to
death or total disability, participants become 100% vested in their entire
accounts. Forfeited nonvested account balances are used to reduce future Company
matching contributions or pay Plan administrative expenses.

                                       4

PAYMENT OF BENEFITS

Upon retirement or other termination of employment, a participant may receive
his vested account balance as a lump-sum distribution. Participants with
balances of $5,000 or less are paid an automatic lump sum distribution as soon
as administratively feasible after termination of employment or retirement.

Unless otherwise provided for in the covered group's special appendix to the
Plan, a participant may make an in-service withdrawal as described in this
paragraph. A participant who has attained age 55 may elect to make an in-service
withdrawal, but if such a participant has not attained age 59 1/2, the amount of
such withdrawal is limited to the vested portion of the participant's Company
matching contributions account. A participant who has attained age 59 1/2 may
elect to make an in-service withdrawal of all or a portion of his vested account
balance. A participant may elect at any time to make an in-service withdrawal of
the balance in his rollover contributions account.

PARTICIPANT LOANS

Active participants who have not had a loan during the previous three months may
obtain a loan with a term not to exceed 4 1/2 years. Participants may have only
one loan outstanding at any time and may borrow from their accounts a minimum of
$1,000 up to a maximum equal to the lesser of $50,000 minus the highest
outstanding loan balance during the previous 12 months, or 50% of their vested
account balances. The interest rate charged is the Federal Reserve's prime rate
(posted in the Federal Reserve's release) as in effect as of the end of the
month prior to the month in which the loan is requested. Principal and interest
are paid through payroll deductions or manual loan payments if a participant is
on an unpaid leave of absence.

PLAN TERMINATION

Although it has not expressed intent to do so, the Company has the right to
discontinue its contributions at any time and to terminate the Plan subject to
the provisions of ERISA. In the event of Plan termination, participants would
become 100% vested in their accounts.

ADMINISTRATION

The Plan is currently administered by the Pactiv Corporation Benefits Committee.

2. SUMMARY OF ACCOUNTING POLICIES

BASIS OF ACCOUNTING

Financial statements of the Plan are prepared using the accrual basis of
accounting.

PARTICIPANT ACCOUNTS

Each participant's account is credited with the participant's and the Company's
contributions, and an allocation of Plan earnings (losses). Allocations of
earnings (losses) are based on account balances, as defined in the Plan. The
benefit to which a participant is entitled is the balance in his account.

EXPENSES

Substantially all Plan administrative expenses are paid for by the Plan,
including recordkeeping and trustee fees.

USE OF ESTIMATES

The preparation of financial statements in conformity with U.S. generally
accepted accounting principles requires management to use estimates and
assumptions. Actual results could differ from such estimates.


                                       5


INVESTMENT VALUATION

Shares of registered investment companies are valued at quoted market prices,
which represent the net asset values of shares on the last business day of the
Plan year. The fair value of common stock is determined using quoted market
prices. Participant loans are stated at their outstanding balance, which
approximates fair value.

3. RISKS AND UNCERTAINTIES

The Plan invests in various investment securities. Investment securities are
exposed to various risks such as interest rate, market credit risks. Due to the
level of risk associated with certain investment securities, it is at least
reasonably possible that changes in the values of investment securities will
occur in the near term and that such changes could materially affect
participants' account balances and the amounts reported in the statements of
assets available for benefits.

4. INVESTMENTS

Investments that represented 5% or more of the fair value of the Plan's net
assets were as follows:



                                                      2004             2003
                                                --------------   --------------

Spartan U.S. Equity Index Fund                       6,544,688        5,712,424




5. INCOME TAX STATUS

The Plan received a determination letter from the Internal Revenue Service dated
November 19, 2002, stating that the Plan is qualified under Section 401(a) of
the Internal Revenue Code (Code) and, therefore, the related trust is exempt
from taxation. Subsequent to this issuance of the determination letter, the Plan
was amended. Once qualified, the Plan is required to operate in conformity with
the Code to maintain its qualification. The plan administrator believes that the
Plan is being operated in compliance with the applicable requirements of the
Code and, therefore, believes that the Plan, as amended, is qualified and that
the related trust is tax exempt.

6. PARTY-IN-INTEREST

The Plan invests in shares of Pactiv Corporation common stock. Pactiv
Corporation is the Plan's sponsor and, therefore, such investments are
party-in-interest transactions. Fidelity Management Trust Company is the trustee
of the Plan and, therefore, Plan investments in various Fidelity-sponsored funds
are considered party-in-interest transactions.
