Item 1.  Security and Issuer

The class of equity security to which this statement on Schedule 13D relates is
the Common Stock (the "Securities") of Sealed Air Corporation, a Delaware
corporation (the "Issuer"). The Issuer has its principal executive offices
located at 200 Riverfront Boulevard Elmwood Park, New Jersey.

Item 2.  Identity and Background

Item 2 shall be amended and restated as follows:

(a)-(c) This statement is being filed by Davis Selected Advisers, L.P. ("Davis
Advisors"), an investment advisor registered with the Securities and Exchange
Commission under the Investment Advisers Act of 1940, as amended. The address
of its principal office is 2949 East Elvira Road, Suite 101, Tucson, Arizona
85756. Davis Advisors provides discretionary portfolio management services,
serving as investment adviser or sub-adviser for registered investment
companies (including the Davis Funds, Selected Funds, and Clipper Fund),
unregistered investment companies, offshore funds, and private accounts.
Davis Advisors also works with sponsors to serve as investment adviser for
managed money/wrap account programs. In certain managed money/wrap account
programs, Davis Advisors will provide non-discretionary investment management
services (generally in the form of model portfolios).

The names, business addresses, and principal occupations of the general partner
and executive officer of Davis Advisors (collectively, the "Principals") are
set forth in Schedule I.

The Securities of the Issuer reported in Item 5 herein were acquired on behalf
of the investment advisory clients of Davis Advisors, Inc., under sole or
shared discretionary authority granted to Davis Advisors. None of the
Securities are owned by or on behalf of Davis Advisors and less than 0.5%
of the Issuer's outstanding securities are owned by Davis Advisors partners
and officers.

(d) During the last five years, none of Davis Advisors, or any of the
Principals has been convicted in any criminal proceeding.

(e) During the last five years, none of Davis Advisors, or any of the
Principals has been a party to any civil or administrative proceeding
that resulted in such person or entity being subject to a judgment,
decree, or final order enjoining future violations of, or prohibiting
or mandating activities subject to, federal or state securities laws
or finding any violation with respect to such laws.

(f) Davis Advisors is a Colorado limited partnership. The citizenship of each
Principal is set forth in Schedule I.


Item 3.  Source and Amount of Funds or Other Consideration

The respective investment advisory clients of Davis Advisors used approximately
$217,593,265 in the aggregate to purchase the Securities reported in this
filing. All funds used to purchase Securities were assets of these respective
clients and none were assets of Davis Advisors. In addition, none of the funds
used to purchase the Securities were provided through borrowings of any nature.


Item 4.  Purpose of Transaction

The Securities reported in this filing have been purchased and held for
investment purposes on behalf of client accounts over which Davis Advisors
has either sole or shared discretionary dispositive or voting power. The
Beneficial ownership on the part of Davis Advisors is expressly disclaimed,
as permitted by Rule 13d-4.  All purchases of Securities were made for
investment purposes only and in the ordinary course of business of Davis
Advisors as a registered investment advisor. Davis Advisors may, from time
to time and at any time, purchase additional securities on behalf of clients
in the future. Davis Advisors reserves the right to sell all or a part of
the current holdings of the Securities from time to time and at any time.

Davis Advisors is engaged in the business of investment management of its
clients' assets and pursues an investment philosophy of identifying undervalued
situations and acquiring positions in undervalued companies on behalf of its
clients.  In pursuing this investment philosophy, Davis Advisors analyzes the
operations, capital structure and markets of companies in which its clients
invest and continuously monitors the business operations of such companies
through analysis of financial statements and other public documents, through
discussions with knowledgeable industry observers, and with management of
such companies.

Davis Advisors qualifies as an institution which may elect to file securities
ownership reports required by the Securities Exchange Act of 1934 on Schedule
13G and, as a routine matter, Davis Advisors utilizes Schedule 13G for its
reporting of the ownership positions held by its investment advisory clients.
As the result of investment analysis or the occurrence of events, Davis
Advisors may desire to participate in discussions with the particular
portfolio company's management or with third parties about significant
matters or possible courses of action to assist in building corporate
intrinsic value per share or to cause the portfolio company's true economic
value to be recognized. In such situations, Davis Advisors may elect to
convert a filing on Schedule 13G to a filing on Schedule 13D in order to
be more active in corporate governance and management matters, and to
have the ability to enter into discussions with third parties
concerning proposed corporate transactions of a significant nature.

On June 1, 2011, via a press release, the Issuer announced that it had entered
into a definitive agreement under which the Issuer will acquire Diversey in a
transaction valued at $4.3 billion. Davis Advisors:

1. has serious concerns about the proposed transaction;
2. may oppose the proposed transaction;
3. may encourage the Issuer's management to explore other strategic options
   to maximize shareholder value; and
4. may have additional conversations with the Issuer and/or third parties
   regarding    opportunities to maximize the Issuer's value including any
   of the actions or transactions enumerated in clauses (a) through (j)
   of Item 4.


Item 5.  Interest In Securities Of The Issuer

Item 5 shall be amended and restated as follows:

(a) The aggregate number and percentage of Securities to which this Schedule
13D relates is 10,267,901 shares of the common stock of the Issuer,
constituting approximately 5.3% of the Issuer's outstanding shares,
Rider 6A.

(b) Davis Advisors generally has the sole power to dispose of or to
direct the disposition of the Securities held for discretionary
accounts of its investment clients, and may be granted the sole
power to vote or direct the vote of such Securities; such powers
may be retained by or shared with the respective clients for shared
or non-discretionary accounts.  Shares held by Davis New York
Venture Fund are reported in the "shared" category.

(c) Please see Schedule II for purchase and sale transactions in
the Securities during the past sixty days.

(d) The investment advisory clients of Davis Advisors have the sole
right to receive and, subject to notice, to withdraw the proceeds
from the sale of the Securities, and the sole power to direct the
receipt of dividends from any of the Securities held for their
respective accounts.  Such clients may also terminate the investment
advisory agreements without penalty upon appropriate notice. Davis
Advisors does not have an economic interest in any of the Securities
reported herein.

(e) Not applicable.


Item 6.  Contracts, Arrangements, Understandings or
         Relationships with Respect to Securities of the Issuer

The powers of disposition with respect to Securities owned by
discretionary private accounts of Davis Advisors are established
in written investment advisory agreements between clients and Davis
Advisors, which are entered into in the normal and usual course of
the business of Davis Advisors as a registered investment advisor
and which are generally applicable to all securities purchased for
the benefit of each such discretionary private account. There are
no special or different agreements relating to the Securities of
the Issuer.

The written investment advisory agreements with clients generally
do not contain provisions relating to borrowing of funds to finance
the acquisition of the Securities, acquisition of control, transfer
of securities, joint ventures, or any of the other transactions
listed in the instructions to Item 6 of Schedule 13D other than
voting of proxies.  In connection with voting, Davis Advisors may
be allowed or directed to vote the proxies received by client accounts.

Item 7.  Material to be Filed as an Exhibit

Item 7 shall be amended and restated as follows:

                                     SIGNATURES
