Abstract
Disclosed are a binary random copolymer of propylene and ethylene, and a film to be formed by sheeting the copolymer. The film has 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 sealant layers of laminate films.
