<p>A multilayer film which comprises outer layers comprising a resin composition (I) or (II) and an inner layer comprising a resin composition comprising a higher melting component (III) and a softening component (IV) interposed between the outer layers, wherein resin composition (I) comprises 59.5 - 99.5 % by weight of (A) an ethylene/ alpha -olefin copolymer component, which comprises at least one copolymer of ethylene and an alpha -olefin having 3 - 20 carbon atoms and which has a melt flow rate (MFR) of 0.1 - 10 g/10 min. and a density of 0.850 g/cm<3> - 0.910 g/cm<3>; 0 - 40 % by weight of (B) a high-pressure process low density polyethylene having a density of 0.915 - 0.930 g/cm<3>, and 0.5 - 10 % by weight of (C) an anti-fogging agent, and wherein resin composition (II) comprises 99.5 - 90 % by weight of (D) an ethylene/vinyl acetate copolymer having a vinyl acetate content of 10 - 30 % by weight and an MFR of 0.5 - 30 g/10 min., and 0.5 - 10 % by weight of (C) anti-fogging agent. The film is useful for packaging and is superior in its extensible elesticity, ability for adhering onto various surfaces, transparency, clear cutting performance, heat-sealability, resistance to fogging, resistance to break-through and in its ability for restoring from finger pressing.</p> |
