Abstract

The invention relates to a film made of a vinyl chloride polymer mixture that, in addition to the conventional additives, contains 0.1 to less than 5 wt % of a semicrystalline or amorphous polyester, has a good thermal formability, and is suitable for the packaging of bulk goods. The film is produced by extruding or by calendering the plastified vinyl chloride polymer mixture, optionally followed by inline/offline stretching and, optionally, thermally formed immediately thereafter.
