Plastic delivery bag, in particular for online delivery trade

Abstract

A plastic delivery bag includes a front bag wall and an opposite rear bag wall, each having an upper edge, a lower edge, and first and second side edges, a closable bag opening and an opposite bag bottom with a bottom fold and a first bottom fold section extending from the lower edge of the front bag wall to the bottom fold and a second bottom fold section extending from the lower edge of the rear bag wall to the bottom fold. The front bag wall and the rear bag wall are connected, in some cases welded together, along or adjacent to their respective first and second side edges, thereby forming first or second connecting areas, in some cases first and second connecting strips or lines. At least one, potentially elongated, first, second, third and fourth weakened areas extend from the transition from the first bottom fold section to the front bag wall, in some cases from the lower edge of the front bag wall, and from the transition from the second bottom fold section to the rear bag wall, in some cases from the lower edge of the rear bag wall, in some cases at least one first, second, third, and fourth perforation lines, at least sectionally adjacent to, and at a spacing from, the first elongated connecting area towards the bag opening in the front bag wall and the rear bag wall as well as the first and second bottom fold sections. At least one elongated other weakened area, in some cases another perforation line, extends from the, potentially elongated, first, second, third, and/or fourth weakened area(s), preferably in a substantially orthogonal orientation, towards the second elongated connecting area.
