SEALED AIR REVISES FULL YEAR EARNINGS GUIDANCE

SADDLE BROOK, N.J., Thursday, September 16, 2004 – Sealed Air Corporation (NYSE:SEE) announced today that it expects 2004 full year diluted earnings per common share to be in the range of $2.60 to $2.70 compared with its previously announced range of $2.80 to $2.90.  The Company expects that near term results will be affected by lower sales to the U.S. beef market and escalating petrochemical-related raw material costs.

Commenting on the Company’s revised outlook, William V. Hickey, President and Chief Executive Officer, stated:

“Our food packaging segment continues to be negatively affected by the import restrictions on U.S. beef products imposed by various countries and the continuing U.S. ban on imports of Canadian cattle.  Industry sources indicate U.S. beef exports are down 90% compared to last year.  This situation is made even more challenging by declining U.S. beef production, which should improve in the future, as efforts are now underway to expand the breeding herd.  In addition, resin costs, which increased during the first half of the year, are continuing to increase.

“While we are not pleased with the short-term impact that these external factors have had on our business, we are encouraged by the continued sales growth of our protective packaging segment resulting from strengthening global demand for our packaging solutions.  Moreover, our food packaging business outside the U.S. is continuing to report sales growth year over year.  We are also taking actions to increase our profitability through improved operating efficiency and productivity going forward.  For example, earlier this year we formulated a supply chain initiative to further improve our purchasing and logistics costs, as well as to help redesign some of our key business processes.  Overall, we believe that Sealed Air is well-positioned for long term growth with our strong fundamentals and our focus on operational initiatives to drive sales growth and productivity improvement heading into 2005.”

Sealed Air expects to report its third quarter 2004 results on Wednesday, October 27, 2004.
