摘要：
The present invention relates to a film for use in stretch-packaging that comprises an intermediate layer which contains as its main component an .alpha.-olefin-series resin component containing a butene-1-series resin and at least two surface layers each containing an ethylene-vinyl acetate copolymer resin as its main component, the surface layers being laminated over both surfaces of the intermediate layer. The film has remarkably high values of tear strength and recovery from deformation.
