HEAT-SEALABLE CROSSLINKED ORIENTED POLYETHYLENE FILM AND PRODUCTION THEREOF

摘要

HEAT-SEALABLE CROSSLINKED ORIENTED POLYETHYLENE FILM AND PRODUCTION THEREOF Disclosed are a heat-sealable crosslinked oriented polyethylene film having low-temperature heat sealability which enables high-speed bag making, improved in antiblocking property and excellent in clarity and moistureproofness, comprising a crosslinked, biaxially oriented high density polyethylene film in which the degree of crosslinking inwardly decreases across the thickness of the film, and a heat sealing layer placed thereon, the heat sealing layer being composed of a tackifier and an ethylenevinyl acetate copolymer containing an antiblocking agent or 1,2-polybutadiene containing an antiblocking agent, and a process for the production of the same.
