VINYLIDENE CHLORIDE COPOLYMER RESIN COMPOSITION, PACKAGING FILM PREPARED THEREFROM AND FOOD PACKAGES USING THE FILM

摘要

Attempts to improve the adhesiveness of films prepared from vinylidene chloride resin compositions by incorporating a copolymer (B) of a monomer having at least one carboxyl group into a vinylidene chloride copolymer (A) suffer from a variefy of disadvantages, such as lack of compatibility between the copolymers. These problems are now overcome by using a copolymer (B) containing 50 to 99% by weight of alkyl methacrylate units or of such units and units of another copolymerisable monomer and 50 to 1% by weight of units of a monomer copolymerizable with said alkyl methacrylate and having at least one carboxyl group. The copolymer (B) is incorporated in such an amount that from 0.01 to 5% of the weight of the resin composition is made up of the units containing carboxylic groups. Films of this resin composition can be used to package meats.
