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.

摘要： The present invention provides a heat shrinkable multilayer film excellent in crease-whitening resistance and perforation aptness as well as excellent in low-temperature shrinkability. The present invention also provides a heat shrinkable label formed from the heat shrinkable multilayer film. The heat shrinkable multilayer film of the present invention includes: front and back layers each containing a polyester resin; an interlayer containing a polystyrene copolymer; and adhesive layers each containing 60 to 85% by weight of a polyester resin and 15 to 40% by weight of a polystyrene copolymer. The front and back layers and the interlayer are stacked with the adhesive layers interposed therebetween. The multilayer film has a tensile elongation at break of 30% or higher in the main shrinkage direction.
