发明名称 LAMINATED FILM FOR HEAT SHRINKABLE POLYPROPYLENE SHRINK LABEL AND CONTAINER MOUNTED WITH THE SAME
摘要 PROBLEM TO BE SOLVED: To provide a laminated film for a polypropylene shrink label for improving heating shrinkage factor or particularly a low-temperature shrinkability, and improving a balance between shrink packaging suitability and a recycling efficiency, by reducing a gravity and having an excellent balance between anti-blocking properties and slipperiness and a container such as a PET bottle, a polyolefin bottle, a bottle or the like mounted with the same. SOLUTION: The laminated film for the heat shrinkable polypropylene shrink label has a thickness of a surface layer of 1 to 50% of an overall film thickness. The film is formed by using a resin composition containing a crystalline propylene-α-olefin random copolymer having specific physical properties or 50 to 95 wt.% and a specific alicyclic hydrocarbon resin of 5 to 50 wt.% as an intermediate layer, using a resin composition containing a specific anti- blocking agent of 0.05 to 1.0 pts.wt., with respect to 100 pts.wt. of a crystalline propylene-α-olefin random copolymer having specific physical properties as a surface layer so that the film is at least uniaxially double stretched. The container has the shrink label made of the film mounted thereon.
