Heat Shrinkable Film

Abstract: This heat-shrinkable film comprises a first surface layer, a second surface layer, and an intermediate layer. The intermediate layer is formed between the first surface layer and the second surface layer. The intermediate layer contains a first impact-resistant polystyrene and a second impact-resistant polystyrene. The first impact-resistant polystyrene contains a general-purpose polystyrene and a first rubber component. The second impact-resistant polystyrene contains a styrene-butyl acrylate copolymer and a second rubber component. The particle size of the first rubber component is larger than the particle size of the second rubber component. The blending ratio of the first impact-resistant polystyrene in the intermediate layer is greater than 0 weight% and less than 45.7 weight%.
