HEAT-SHRINKABLE MULTILAYER FILM AND HEAT SHRINKABLE LABEL

摘要

The present invention provides a heat shrinkable multilayer film that has excellent adhesiveness between front and back layers and an interlayer, effectively prevents delamination, and is less likely to have white creases on folds. The present invention also provides a heat shrinkable label formed from the heat shrinkable multilayer film. The present invention relates to a heat shrinkable multilayer film, including: front and back layers each containing a polyester resin; an interlayer containing a polystyrene resin; and adhesive layers, wherein the front and back layers and the interlayer are stacked with the adhesive layers interposed therebetween, and the adhesive layers each contain 50 to 95% by weight of a polystyrene resin and 5 to 50% by weight of a polyester elastomer.
