ABSTRACT:
A preformed web and a method of producing dunnage units from the preformed web. The web is an elongate flattened thermoplastic tube having an inflation edge and an opposite edge. The tube includes spaced transverse seals that define sides of pouches. In one embodiment, the web is configured such that a gap forms between each pair of adjacent pouches when the pouches are inflated. In one embodiment, an inflation edge of the web comprises a frangible connection that allows the inflation edge to be broken by an unsharpened object.
