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 copolymerwhich 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.
