HEAT-SHRINKABLE POLYOLEFINIC FILM

摘要

PROBLEM TO BE SOLVED: To provide a heat-shrinkable polyolefinic film having good solvent adhesiveness due to an organic solvent and preventing the mutual blocking of labels in a heater at the time of selling under heating in an automatic vending machine or the like. SOLUTION: The heat-shrinkable polyolefinic film is constituted by laminating cycloolefinic resin layers [B] on the upper and under surfaces of a layer [A] based on a polypropylene resin while a cycloolefinic resin layer [C] having a glass transition temperature higher than that of the layer [B] is laminated at least on one side thereof to constitute the heat-shrinkable polyolefinic film of which the heat shrinkage factor at the time of immersion in hot water at 95°C for 10 sec is 50% or above.
