Abstract
The present invention is directed to a heat-sealable propylene-based polymer composition comprising a propylene polymer composition including a propylene polymer component and propylene/ethylene random copolymer component; an ethylene/α-olefin random copolymer; and a soft propylene polymer composition. The present invention also provides a heat-sealable film using the composition and a packaging bag comprising the film. The heat-sealable film of the present invention has high heat-seal strength, with little decrease in heat-seal strength even after heat treatment. The heat-sealable film also has excellent blocking resistance, rigidity and low-temperature impact resistance.
