Document Type and Number:
Japanese Patent JPH09502672
Kind Code:
A
Abstract:
An oxygen and moisture impermeable multilayer barrier film which is free of halogens and which may be produced by coextrusion or lamination techniques is provided. The film provides excellent adhesion between layers, has quietness, odor barrier, and softness characteristics, and provides a heat sealable surface for the fabrication of bags. The barrier film includes a halogen-free barrier layer and at least one heat sealable skin layer. The heat sealable skin layer includes either a thermoplastic polyurethane, a substantially linear copolymer of ethylene and an alpha -olefin having a density in the range of from about 0.87-0.92 gm/cc and from about 0.01 to 3 long chain branches/1000 carbon atoms along the polymer backbone, a homogeneously-branched linear polyolefin resin, or a blend of an ultra low density polyolefin resin with a copolymer of ethylene and vinyl acetate.
