ABSTRACT:
Film packaging for right parallelepiped articles, in which the film parts are welded by heat sealing, is provided with a tear aid in the form of an additional, advantageously arranged imprint which prevents heat sealing in one or more desired areas. The reliability of film removal is additionally increased by means of a plurality of oblique prints and imprint areas one covering the other. The packaging can be used for articles of all types where complete removal of all packaging parts is necessary, for example for tape cassettes, in particular for magnetic tape cassettes.
