LOW-CRYSTALLINE PROPYLENE RANDOM COPOLYMER COMPOSITION, PROCESS FOR PRODUCTION THEREOF, AND COMPOSITE LAMINATED POLYPROPYLENE STRUCTURE

摘要

A novel low-crystalline propylene random copolymer composition comprising [I] 60 to 95 % by weight of a propylene random copolymer and [II] 5 to 40 % by weight of a low-crystalline propylene random copolymer which has excellent heat-sealability, heat-seal imparting property, transparency and antiblocking property and containing a reduced amount of a hydrocarbon-soluble component, a process for production thereof, and polypropylene composite laminated structure having improved heat-sealability and heat seal strength at low temperatures.
