摘要:
Packaging propylene resin compositions are excellent in balance in high transparency, rigidity, low-temperature impact resistance and blocking resistance. Retort films, protective films, medical container packaging films and freshness-keeping films, and sheets for similar purposes are obtained from the compositions. A packaging propylene resin composition includes a propylene polymer (A) satisfying specific requirements and a propylene/ethylene copolymer (B) satisfying specific requirements. In another packaging propylene resin composition, Dinsol and Dsol satisfy specific requirements.
