Patent number: 7659343Abstract: Film layers made from formulated ethylene polymer compositions are disclosed. Film layers made from such formulated compositions have surprisingly good heat seal properties, and an especially good reduction in heat seal initiation temperature. The ethylene polymer compositions have at least one homogeneously branched ethylene/alpha-olefin interpolymer and at least one homogeneously or heterogeneously branched ethylene polymer which has a lower melt index than the first mentioned component. The first homogeneously branched ethylene/alpha-olefin interpolymer has a melt index higher than that of the formulated composition.Type: GrantFiled: June 2, 2004Date of Patent: February 9, 2010Assignee: Dow Global Technologies, Inc.Inventors: Jeffrey J. Wooster, Thomas Oswald, Staci A. DeKunder, Jesus Nieto

Patent number: 6086967Abstract: The subject invention pertains to a film structure suitable for the packaging of perishable food, comprising at least one film layer which in turn comprises a blend of at least one homogeneous linear or substantially linear ethylene polymer and at least one polypropylene polymer, wherein the film structure is characterized as having a 2% secant modulus which is at least 8% greater than a comparable film structure prepared without the polypropylene polymer, an oxygen transmission rate of at least 700 cc(at STP)-mil/100 in..sup.2 -day-atm at 25.degree. C. The inventive film structures exhibit an optimized balance of properties, making them especially useful in modified atmosphere packages for perishable goods. The inventive films are particularly suited for the packaging of fresh fruits, vegetables, and other perishable items which would benefit from controlled access to environmental oxygen.Type: GrantFiled: November 6, 1996Date of Patent: July 11, 2000Assignee: The Dow Chemical CompanyInventors: Nicole F.
