<p>A film having superior seal strength and barrier properties comprises a base layer comprising 70 to 97 weight % of a polyolefin, e.g. polypropylene, and 3 to 30 % weight of a resin of lower molecular weight than the polyolefin, e.g. a hydrogenated petroleum resin. On at least one of the surfaces of the base layer is a l to 20 weight % of a film of a random copolymer of 80 to 99 weight % of propylene and l to 20 weight % of ethylene, for example, an isotactic propylene-ethylene copolymer</p> |
