摘要： The disclosed heat-sealable, layered film comprises a polyolefinic base layer and at least one outer layer. The outer layer comprises a propylene-olefin copolymer prepared by means of a metallocene catalyst. The film is prepared by coextruding melts corresponding to the individual layers of the film, taking off the coextruded film over a take-off roll whose temperature is between 10 and 90° C., biaxially stretching and then heat-setting the resulting film, and optionally corona- or flame-treating the film, then winding it up in a wind-up unit.
