Heat-shrinkable film for a resin composition, heat-shrinkable films, and bottles it was wound around

摘要

PPROBLEM TO BE SOLVED: To provide a resin composition giving a heat-shrinkable film shrinkable at a low temperature, having not too high and moderate shrinking gradient and excellent property to hold the shape of a bottle, and provide a heat-shrinkable film produced by processing the resin composition for heat-shrinkable film, and a bottle wound with the film. PSOLUTION: The resin composition for heat-shrinkable film comprises (A) a styrene-(meth)acrylate copolymer and (B) a block copolymer having (b1) a styrenic polymer block and (b2) a conjugated diene polymer block, wherein the styrene-(meth)acrylate copolymer (A) contains a multi-branched styrene-(meth)acrylate copolymer (a1). The invention further provides a heat-shrinkable film produced from the resin composition for heat-shrinkable film, and a bottle wound with the heat-shrinkable film. PCOPYRIGHT: (C)2008,JPO&INPIT
