<p>PROBLEM TO BE SOLVED: To provide a laminated film for a polyolefinic shrink label enhanced in heat shrinkage factor, especially, low temperature shrinkability, reduced in natural shrinkage factor and enhanced in the balance between shrink packaging properties and recycling efficiency by the reduction of specific gravity, and a container provided therewith. SOLUTION: The laminated film for the polyolefinic shrink label is composed of a surface layer comprising a cycloolefinic resin and a substrate layer comprising a resin composition containing 50-95 wt.% of a crystalline propylene/α-olefin random copolymer having specific physical properties and 5-50 wt.% of a specific alicylic hydrocarbon resin and stretched twice or more at least uniaxially and characterized in that the thickness of the substrate layer is 50-99% of the total thickness of the film, the specific gravity of the laminated film is not more than 0.95 and a natural shrinkage factor is not more than 3%. The container having the label comprising the laminated film is also disclosed.</p> |
