Patent number: 6984442Abstract: A multilayer film includes a first layer comprising an amorphous polymer that exhibits a glass transition temperature, and a second layer forming an exterior layer of the multilayer film and comprising a sealant material capable of forming a heat-seal, the sealant material comprising a polymer that exhibits a melting point. The glass transition temperature of the amorphous polymer is greater than the melting point of the sealant material by at least about 45 degrees centigrade.Type: GrantFiled: July 19, 2002Date of Patent: January 10, 2006Assignee: Cryovac, Inc.Inventors: Herve M. Brebion, Frank M. Hofmeister, Ram K. Ramesh, Paul J. Satterwhite

Patent number: 6858313Abstract: A film includes a core layer having an amorphous polyamide; two intermediate layers, disposed on opposite surfaces of the core layer, including a semicrystalline polyamide; two adhesive layers, each disposed on a surface of the respective intermediate layer, including a polymeric adhesive; and two outer layers, each disposed on a surface of a respective adhesive layer, including an ethylene/alpha olefin copolymer, propylene homopolymer, or propylene/alpha olefin copolymer; and a second outer layer, disposed on a surface of a respective adhesive layer, including amorphous polyamide, semicrystalline polyamide, ethylene/alpha olefin copolymer, propylene homopolymer, or propylene/alpha olefin copolymer. The film can alternatively have a core layer including a polymeric adhesive, and two intermediate layers each having an amorphous polyamide. A method of packaging a product using these films, and a package, are also disclosed.Type: GrantFiled: August 2, 2002Date of Patent: February 22, 2005Assignee: Cryovac, Inc.Inventors: Carlo E.

Patent number: 5885699Abstract: A multilayer film characterized by having excellent oxygen permeability and thermoformable properties comprising a sealant layer and a heat resistant layer is disclosed. The sealant layer contains an ethylene based polymer or copolymer. The heat resistant layer has a melting point greater than that of the polymeric composition of the sealing layer. Internal layers also can be provided.Type: GrantFiled: January 28, 1997Date of Patent: March 23, 1999Assignee: Cryovac, Inc.Inventors: Richard K. Watson, William D. Mayfield, Paul J. Satterwhite

Patent number: 5837358Abstract: A packaged product has a cooked meat product, within a film, adhered to a meat-contact surface of the film. An anhydride functionality is present on the meat-contact surface of the film. Upon extraction in ethanol, the anhydride is extractable from the cook-in film to a level of less than 50 parts per billion. A packaged product is prepared by packaging a meat product in the cook-in film and cooking the meat product within the film so that the meat-contact surface of the film adheres to the meat product.Type: GrantFiled: June 1, 1995Date of Patent: November 17, 1998Assignee: W.R. Grace & Co.-Conn.Inventors: Frank T. Bauer, Thomas D. Kennedy, Ram K. Ramesh, Paul J. Satterwhite, John S. Sczesny, G. Vincent Sharps, Richard K. Watson
