In the first processing area the foils can e.g. be pre-formed or pre-cut. By separating the foil path into these three different processing areas, it becomes possible that the two adjacent foils are pre-processed in the first processing area while there is enough space for introduction of the spout in the second processing area.

Abstract: The web for a dual chamber tubular container can be maintained in an alignment across the container by providing one or more longitudinal modified areas on the web so that the web will yield and fold in the areas of the modified material. The modification will be a thinning or weakening of the web to produce yield points, such as fold points. This thinning or weakening can be produced mechanically or chemically. Mechanically, a pinch or other shaped roll can be used to thin or weaken an area. Thermally, heat can be applied. The result is a web that remains in an alignment across a tubular chamber rather than in close contact with the sidewall.

Abstract: A bag pack comprises a plurality of easy open handle bags. The bags are easy to open because the exterior surfaces of the bags are cold-welded together so that when one bag is pulled from the pack, the adjacent next bag is at least partly open. The external surfaces of the bags are not welded to the internal surfaces of the bags during the pressure welding process, because the material that forms the external surface of the bag is treated with a corona discharge, which renders the external surface more susceptible to cold weldings. Optionally a static charge is induced on the bags so that each bag is at a different voltage than the adjacent bags so the bags attract each other, and the panels of each individual bag repel each other, to contribute to the easy open feature.

Where the strip does not take up the entire width of the interlayer, it has a preselected, constant width and runs parallel to the zipper profiles. The lower melting point of the material of the strip, and the width of the strip, ensure that the seal location on the profiles remains fixed.
