Packaging bag comprising an external packaging

Abstract

A packaging bag ( 10 ) that is made of a flexible film-shaped first material and includes an opening part ( 26 ) which can be cut along a tearing line ( 24 ) extending perpendicular to a longitudinal axis of the bag as well as an external packaging ( 30 ) made of a substantially dimensionally stable second material. The openings of the tubular external packaging ( 30 ) lie on a plane that runs vertical to the axis of the tube while the end of the bag which protrudes from the external packaging ( 30 ) can be folded inside out over the edge of the external packaging ( 30 ) after cutting the opening part ( 26 ).
