Abstract
Heat-sealing tool for sealing plastic films, having a sealing tape made of an electrically conductive material. A width of the sealing tape is 2 mm to 1000 mm, a length of the sealing tape is 2 mm to 2000 mm and a thickness of the sealing tape is 0.1 mm to 4 mm, and a largest surface of the sealing tape is provided with a plurality of recesses, in which a sum of cross-sectional areas of the recesses in a cross-sectional plane aligned parallel to the largest surface amounts to a maximum of 50 percent of an area of the largest surface.
Claims18
A heat-sealing tool for sealing plastic films, having a sealing tape made of an electrically conductive material, wherein a width of the sealing tape is 2 mm to 1000 mm, a length of the sealing tape is 2 mm to 2000 mm and a thickness of the sealing tape is 0.1 mm to 4 mm, and wherein a largest surface of the sealing tape is provided with a plurality of recesses, wherein a sum of cross-sectional areas of the recesses amounts to a maximum of 50 percent of an area of the largest surface.
A heat-sealing tool for sealing plastic films, having a sealing tape made of an electrically conductive material, which has a first contact region at a first end region for making electrical contact with a first electrode and a second contact region for making electrical contact with a second electrode, and which is provided in a heating region, which is formed between the first contact region and the second contact region, with at least one recess from the group:
- through-hole, notch, meander cut, so that a distance between the first contact area and the second contact area is smaller than a length of an electrical path between the first contact area and the second contact area.
