SHRINK FILM AND SHRINK LABEL

摘要

PROBLEM TO BE SOLVED: To provide a shrink film prevented from delamination, in a laminated shrunk film made of different polymers of a polystyrene resin and a polyester resin, and also to prevent a shrink label using the shrink film. SOLUTION: The shrink film includes at least three layers. A surface layer [layer A] is composed of a resin composition containing an amorphous aromatic polyester resin as a main component and a plasticizer in an amount of 0.5-20 pts.wt. per 100 pts.wt. of the polyester resin, and a central layer [layer B] is composed of a resin composition containing a styrene-conjugated diene copolymer and/or its hydrogenated product as main components. The layers are laminated in the order of layer A/layer B/layer A. COPYRIGHT: (C)2009,JPO&INPIT
