A multi-layer film having an intermediate layer containing, as a main component, a mixture of two kinds of specific linear low density polyethylenes, and innermost and outermost layers containing, as a main component, a mixture of a specific high pressure process polyethylene, a specific ethylene-.alpha.-olefin copolymer and a specific linear low density polyethylene. The film has an automatic packaging machine applicability and an excellent heat sealability at low temperatures without defects such as lowering of tuck in property, stretchability in the transverse direction and film slipping property and blocking, and is suitably employed as films for stretch packaging and shrink packaging which are used for prepackaging of retailed goods, mainly foods. Further, a multi-layer film prepared by incorporating a specific surfactant composition into at least two layers of the above multi-layer film has, in addition to these properties, an excellent antifogging effect (initial antifogging property and retainability of antifogging property) on various objects to be packaged.
