plastic bag, plastic element and processes for plastic bag manufacturing. The present invention relates to a plastic bag (10) made of a plastic film (20) with one or more doors (30). at least one of these doors (30) has a plastic element (40) that is welded between two layers of plastic film (22, 24), thereby forming the door welding region (50). The plastic element (40) can be compressed to a flattening in a door welding region (50). the unstretched plastic element section (40) when uncompressed forms a wedge directed to the side ends of the door weld region (50). the plastic element (40) has at least one end (80) in the door welding area (50). The plastic bag (10) enables an optimal manufacturing process that is especially applied in the medical sector. |
