Low-crystalline propylene random copolymer composition, process for production thereof, and polypropylene composite laminated 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.
