To provide a heat-shrinkable polyolefinic film advantageous in productivity because of its capability of being formed into a cylindrical label by using a solvent seal, capable of being separated from PET based on a difference in specific gravity because of its specific gravity of below 1 and advantageous to recycle.

In a heat-shrinkable polyolefinic film consisting of at least three layers, both surface layers are constituted of a cyclic olefinic copolymer resin with a glass transition temperature of 50-75°C and an intermediate layer is constituted of a resin composition based on a polypropylene type copolymer resin and the total thickness of both surface layers is 10-40% with respect to the total thickness of the film and the thickness of the intermediate layer is 60-90%. The heat shrinkage factor of the film measured when the film is immersed in a glycerine bath at 100°C for 30 sec is 40% or more in a main shrink direction and 15% or less in the direction crossing the main shrink direction at a right angle.
