Vinylidene chloride copolymer resin composition, packaging film prepared therefrom and food packages using the film. |
摘要 |
<p>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.</p> |
