Thermoforming food packaging film, thermoforming food packaging multilayer film, deep-drawing packaging film, and skin pack film

摘要

PROBLEM TO BE SOLVED: To provide a food packaging film for thermoforming, which has excellent gas barrier properties, transparency, and formability during secondary processing, a multilayer food packaging film for thermoforming, a film for deep-drawing packaging and a skin pack using these films. Provide a film for use. SOLUTION: The resin composition is mainly composed of a saponified ethylene-vinyl acetate copolymer (A) and a polyolefin elastomer (B) having a composition ratio of (A)/(B)=71/29 to 99/1. A food packaging film for thermoforming having a gas barrier layer as a component, wherein the polyolefin-based elastomer (B) is an ethylene-methacrylic acid copolymer, and the gas barrier layer is stretched in the transverse direction (TD) at 110°C. In the test, the tensile stress (S
