Patent

CA 2592780

The invention relates to a film bag that is formed by means of folding a film (1), has a front surface (2), a back surface (3), a laid-in first side fold (4) as well as a laid-in second side fold (5), and is closed off by means of a longitudinal sealing seam as well as a head sealing seam (7) A re-closure strip (8) is attached on the inside surface of the film bag, below the head sealing seam (7), which strip releasably connects the first side fold (4) with the adjacent front surface (2) and back surface (3) of the bag. The first side fold (4) forms a re-closable chute when a bag segment is removed above the re-closure strip (8) to remove goods filled into the bag. According to the invention, the head sealing seam (7) is configured in step shape, whereby a first segment (13) of the head sealing seam extends from the outside edge (11') of the second side fold (5) all the way to the ends of the re-closure strip (8) attached to the inside of the front and back surfaces (2, 3), and whereby the head sealing seam has a second segment (15) that follows the first in step shape, which connects a bag segment (9) that projects upward, at the edges, forming a seal, and extends all the way to the outside edge of the bag, along the first side fold. The projecting bag segment can be removed entirely or in part, along a separating line (16) disposed above the re-closure strip (8). - Fig. 1
