Title:
接着性樹脂組成物および易剥離性フィルム
Document Type and Number:
Japanese Patent JP7206747
Kind Code:
B2
Abstract:
To provide an adhesive resin composition excellent in low-temperature sealability, less in paper peel off of a paper container when releasing, small in degree of variation of a release strength, and small in change in adhesive strength even after storage under an environment at a high temperature and a high humidity, and an easily releasable film using the same.SOLUTION: The adhesive resin composition includes: 50 pts.wt. or more and 90 pts.wt. or less of an ethylene-vinyl acetate copolymer (A) having a vinyl acetate content measured by JIS K6924-1 of 3 wt% or more and 15 wt% or less, and a melt mass flow rate measured by JIS K6924-1 of 1 g/10 min. or higher and 40 g/10 min. or lower; 3 pts.wt. or more and 30 pts.wt. or less of at least any resin (B) of a crystalline or amorphous resin having a glass transition temperature of 60°C or higher and 120°C or lower, or a copolymer including a block segment having a glass transition temperature of 60°C or higher and 120°C or lower in a molecular structure; and 5 pts.wt. or more and 20 pts.wt. or less of a tackifier (C), where the total of (A), (B), and (C) is 100 pts.wt.SELECTED DRAWING: None
