Abstract: Disclosed is a sealable, biaxially stretched polyethylene-coated polypropylene film, preferably manufactured as a flat film, which is not only extremely scratch-resistant but is also rapidly sealable, with good machine-running characteristics and high transparency. The polyethylene sealing layer has a scratch resistance of .ltoreq.50% gloss reduction, relative to an initial gloss of 100%, measured according to ASTM Standard Specification D673-70 (1976), and a density of .gtoreq.0.94 g/cm.sup.3, preferably of .gtoreq.0.95 g/cm.sup.3. Also disclosed is a process for the manufacture of the film, and the use of the film as an abrasion-resistant packaging material.
