Abstract:
A layered heat-shrinkable film having at least three layers, or both outer layers and an intermediate layer, wherein the heat shrinkability in the main shrinkage direction of the film is 20% or higher after treatment in hot water at 70Â° C. for 5 seconds and 35% to 55% after treatment in hot water at 75Â° C. for 5 seconds and 50% to 60% after treatment in hot water at 80Â° C. for 5 seconds, and the compressive strength of a label formed from the film meets the following formula (1):Y>X2.2â€ƒâ€ƒ(1) where Y is compressive strength (mN) and X is film thickness (&mgr;m).
