<p>PROBLEM TO BE SOLVED: To provide a heat-shrinkable film that has sufficient fracture resistance of the film and excellent transparency and low-temperature shrinkage characteristics, and that is suitable to be used for shrink packaging, shrink binding packaging, shrink labels, or the like.SOLUTION: The heat-shrinkable film essentially comprises a mixture resin composition of a polylactic acid-based resin (A) and a thermoplastic polyurethane elastomer (B) in which an isocyanate component essentially comprises an aliphatic isocyanate and/or an alicyclic isocyanate, with a mixing ratio (A)/(B) ranging from 95 mass%/5 mass% to 50 mass%/50 mass%, and is stretched in at least one direction. When the film is immersed in hot water at 80°C for 10 seconds, a heat shrinkage percentage of the film is 20% or more and 70% or less in the main shrinking direction; and the film has a haze value of 10% or less according to JIS K7136.</p> |
