Bag or sack produced by applying adhesive to base layers of end section of tubular walled section, has fold line, cut edge, and fold edge.

摘要

The layers of paper and or plastic forming the walls of the flat tubular section (1) overlap on the side of the base. The layers following an outer wall each only partially cover the previous layer. The two inner layers can be of equal length. The superimposed end parts, after adhesive has been applied, are folded over on a fold line (4) near the cut edge (9) of the other outer layer on the adjoining side of this outer layer. The adhesive application (10) is applied over a length corresponding to the length of the superimposed end parts (2,5,7,6), adjoining the fold edge (8) on the outside of the other outer layer (3).
