POLYETHYLENE-BASED TUBULAR BIAXIALLY ORIENTED FILM |
摘要 |
PROBLEM TO BE SOLVED: To obtain an ethylene-based resin tubular biaxially oriented film that has excellent transparency and see through feeling and prevents whitening. SOLUTION: The polyethylene-based tubular biaxially oriented film comprises a polyethylene-based resin and an inorganic antiblocking agent master batch in which a resin for the master batch is an ethylene-α-olefin copolymer having 0.86-0.91 g/cm<SP>3</SP>density. The polyethylene-based tubular biaxially oriented film has a three or more multilayer structure in which at least both surface layers are composed of a polyethylene-based resin and an inorganic anti-blocking agent master batch and the resin for the master batch is an ethylene-α-olefin copolymer having 0.86-0.91 g/cm<SP>3</SP>density. The resin for the master batch is an ethylene-α-olefin copolymer having a melting calorie at≤110°C of≥90% total melting calorie in a melting curve by a differential scanning calorimeter.
