摘要：Improved polymer compositions, useful in the manufacture of closures and as liners for reclosable container closures, comprising blends of semicrystalline poly(1-butene), ethylene-methylene acrylate, polypropylene random copolymer, wherein the polypropylene random copolymer and the ethylene methyl acrylate can be used singularly or in combination, a lubricating agent and optionally, low density polyethylene. The inventive polymer compositions are recyclable, and do not present the environmental, health, and odor problems associated with polymer liners known in the art.
