Title:
THERMOPLASTIC RESIN COMPOSITION, COVER MEMBER AND EASILY OPENABLE CONTAINER
Document Type and Number:
WIPO Patent Application WO/2016/140322
Kind Code:
A1
Abstract:
The present invention provides a thermoplastic resin composition which has easy openability by means of cohesive peeling, excellent formability by extrusion laminating and sufficiently high heat seal strength, and which is capable of forming a seal layer having excellent easy openability, formability by extrusion laminating, peeling appearance or the like. The present invention relates to a thermoplastic resin composition which contains 60-84% by weight of component (A), 3-23% by weight of component (B) and 3-28% by weight of component (C).
Component (A): A crystalline polyester that contains an aliphatic dicarboxylic acid unit and has a melting peak temperature of 110-140°C.
Component (B): An amorphous polyester and/or a polyolefin.
Component (C): A styrene-based thermoplastic elastomer that is composed of at least one substance selected from the group consisting of block copolymers having a polymer block P derived from a vinyl aromatic compound and a polymer block Q derived from a conjugated diene and hydrogenated products of the block copolymers, wherein the total of 1, 2-bond units and 3, 4-bond units in the block Q is 60% by mole or more.
