<p>PROBLEM TO BE SOLVED: To provide a polyethylene multilayer film which is excellent in balance between impact resistance and rigidity and excellent in transparency and moldability.SOLUTION: There is provided a polyethylene multilayer film in which an A layer, which contains 41 to 99 wt.% of a specific ethylene-α-olefin copolymer (A) having less long-chain branched structure and 1 to 59 wt.% of an ethylene-based polymer (B) having a specific long-chain branched structure characterized by elongational viscosity behavior, is used as a core layer and a B layer, which contains 70 to 100 wt.% of the ethylene-α-olefin copolymer (A) and 0 to 30 wt.% of a high-pressure method low-density polyethylene (C), is used as a surface layer.</p> |
