Heat-shrinkable thermoplastic resin films
Heat-shrinkable thermoplastic resin films suitable for use as labels on the bottles, particularly as full labels on the PET bottles, wherein the heat shrinkability in the main shrinkage direction of the film is 5% to 60% after treatment in hot water at 70&deg; C. for 5 seconds and 67% or higher after treatment in hot water at 85&deg; C. for 5 seconds and the heat shrinkability in a direction perpendicular to the main shrinkage direction of the film is 10% or lower after treatment in hot water at 85&deg; C. for 5 seconds. When used as full labels on the bottles, these films can have good shrinkage finish because they cause only rare occurrence of wrinkles, shrinkage spots, and strains during heat shrinkage, and they are therefore extremely useful as full labels.
