Resealable packaging bag

Abstract

A resealable packaging bag should be produced in the simplest way and at minimal cost. It consists of flexible material and has an opening ( 5 ) at the top. Non-detachably fixed on one side of the bag is a backing ( 6 ), and detachably fixed to the backing ( 6 ) is a section ( 10 ) of a flexible material provided with a self-adhesive layer. A portion of the backing ( 6 ) and a portion of the section ( 10 ) project beyond the opening edge ( 14 ) of the bag. To close the bag, a portion ( 8 ) of the backing ( 6 ) is peeled off, and the now exposed portion of the section ( 10 ) is placed over the opening ( 5 ) and is stuck onto the opposite side ( 2 ). Used for opening and resealing is the detachably adhering portion of the section ( 10 ) which is on the portion ( 9 ) of the backing ( 6 ) remaining on the bag. The advantages are in particular that the bag can be produced from any desired material including paper and that the backing with the self-adhesive section can be a commercially obtainable self-adhesive label.
