    摘要： Disclosed are a binary random copolymer of propylene and ethylene, and a film to be formed by sheeting the copolymer. The film has good impact strength, good heat-sealability, high stiffness, good anti-blocking and slipping properties, and high transparency. As having excellent heat-sealability at low-temperature, the copolymer and its film are favorably used as substrate layers of laminated or co-extruded multi-layered films.
