<p>PURPOSE: Provided are a layered heat-shrinkable films for label use, which cause only rare occurrence of wrinkles, shrinkage spots and strains by heat shrinkage, and in which films high compressive strength is compatible with bonding properties when non-halogen solvents are used, and a labels for bottles. CONSTITUTION: The layered heat-shrinkable film has at least three layers, or both outer layers and an intermediate layer. The heat shrinkage rate in the main shrinkage direction of the film is 20% or higher after treatment in hot water at 70 deg.C for 5 seconds and 35% to 55% after treatment in hot water at 75 deg.C for 5 seconds and 50% to 60% after treatment in hot water at 80 deg.C for 5 seconds, and the compressive strength of a label formed from the film meets the following formula (1): Y>X2.2 (wherein Y is compressive strength(mN) and X is film thickness(micrometer)).</p> |
