Method for producing a flexible packaging films with reclosure

摘要

The method involves feeding a pouring-hole film strip (3) to a film web. The film strip is applied with a film strip-seal layer (23) on a side of the film web, which form a film inner side (10) of a packaging film (2) with proper use of the packaging film in such a way that tensile force is transferred to a separating region in the film strip seal layer by a pull tab (12) in the packaging film. The separating region and a neighboring region of a contact adhesive layer (24) form a resealable closure for interaction with the pull tab. An independent claim is also included for a pouring-hole film strip comprising a three-layered structure.
