Business Editors

MINNEAPOLIS--(BUSINESS WIRE)--June 19, 2002

Bemis Company, Inc. (NYSE:BMS) today announced that it has reached agreement to acquire the global Clysar(R) shrink film business of E.I. duPont de Nemours and Company ("DuPont"). Clysar(R) is a global supplier of premium polyolefin shrink film used primarily in total over-wrap applications for the display, protective packaging and food markets. The Clysar(R) business operates plants in Clinton, Iowa and Le Trait, France. Closing is subject to normal closing conditions and regulatory approval and is expected in early August. Terms of the agreement were not disclosed.

Commenting on the pending acquisition, Jeffrey Curler, President and CEO of Bemis Company, Inc. said, "I am very pleased to be adding the Clysar(R) brand to our flexible packaging product line. The Clysar(R) brand broadens our product reach to the worldwide industrial shrink film market, bringing with it sophisticated, patented technology and a strong customer distribution system. This acquisition will enrich our existing oriented film capabilities, which include shrink bags, industrial shrink film and heat set polyester and polypropylene. Combined with Bemis' premier high barrier technology, this unique orientation process will also offer our research engineers new opportunities to generate proprietary packaging solutions for our global food and consumer products customers.

Clysar(R) will become part of the high barrier product line of our flexible packaging segment and is expected to contribute in excess of $100 million in sales in 2003. This business will continue to operate from the existing Clysar(R) facilities. With a talented Clysar(R) workforce already in place, we expect this acquisition to be modestly accretive to Bemis' EPS in 2002."
