接着性樹脂組成物、それを用いたシート、蓋材、密封容器用部材セット、および開封可能な容器
Document Type and Number:
Japanese Patent JP6922590
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an adhesive resin composition which has sealing strength enough to seal a content while having easy openability when heat-sealed on a surface of a PET container, has no problem in peeling appearance such as stringiness after peeling of a lid material, and is excellent in blocking resistance and coating suitability.SOLUTION: An adhesive resin composition contains an ethylene-vinyl acetate copolymer (A), polybutene-1 (B), an ethylene-octene copolymer (C) and a tackifier resin (D) with ratios in specific ranges. The adhesive resin composition contains an ethylene-octene copolymer having an MFR of 300-1,500 g/10 min in the adhesive resin composition to thereby easily cause cohesion failure, and is particularly excellent in easy openability and peeling appearance to thereby satisfy all properties of sealing performance, easy openability, peeling appearance, blocking resistance and coating suitability to a PET container.SELECTED DRAWING: None
