<p>PURPOSE:To obtain the film having excellent heat-shrinkable property and heat sealing property by making a heat-shrinkable rate of the propylene ethylene alpha-olefin copolymer film in the lateral or vertical direction at 120 deg.C twice or more of the other directions. CONSTITUTION:The heat-shrinkable rate at 120 deg.C in either the lateral or vertical direction of the film consisting of the propylene ethylene alpha-olefin terpolymer (the carbon number of alpha-olefin is four or more) is made twice or more of the heat-shrinkable rates in the other directions. Accordingly, anisotropic heat- shrinkable film, having excellent heat-shrinkable property, heat sealing property and printing property and being suitable to a sheath material to be stuck onto the outer surface of a material to be packed, can be obtained.</p> |
