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.
