PROBLEM TO BE SOLVED: To provide a heat shrinkable polyolefin laminated film which is suitable, for example, for the label of a PET bottle and excellent in rigidity at room temperature, finger-print whitening resistance, shrinkage finish properties, transparency, natural shrinkage, and regeneration addition properties. SOLUTION: The laminated film has surface and back layers of a mixed resin composition conprising 90-50 mass% of a cyclic olefin resin and 10-50 mass% of a polyethylene resin (A) and an intermediate layer of a resin composition containing the cyclic olefin resin as a main component. The heat shrinkage factor of the film when it is immersed in water of 80°C for 10 s is at least 20% in at least one direction. COPYRIGHT: (C)2006,JPO&NCIPI
