Web and method for making fluid filled units

A method of forming dunnage units, the method comprising:

• providing a preformed flattened tubular web comprising:
• a first elongated layer;
• a second elongated layer superposed over the first elongated layer, the first and second layers connected together at an inflation edge;
• a frangible line of connection disposed in only one of the first and second layers, the frangible line of connection being substantially parallel to the inflation edge and offset from the inflation edge by a first distance;
• a plurality of transverse seals extending to a seal termination point that is a second distance from the inflation edge, wherein the second distance is greater than the first distance;
• a plurality of inflatable pouches defined by the first and second elongated layers, the inflation edge, and the transverse seals;
• and
• a plurality of lines of weakness that allow the inflatable pouches to be separated, the lines of weakness beginning at a starting point transversely located between the inflation edge and the termination point of the transverse seals;
• positioning a separator with respect to the web, such that the separator engages the frangible line of connection in only one of the first and second layers;
• opening the frangible line of connection in only one of the two layers with the separator;
• inflating the inflatable pouches to an inflated volume;
• and
• sealing the inflated pouches to convert the inflated pouches to dunnage units.
