Patent ID: 8357439

Claim:
A web for forming dunnage units, comprising: a first elongated layer having an inflation edge and an opposite edge; a second elongated layer having an inflation edge and an opposite edge, wherein the second elongated layer is superposed over the first elongated layer, the first and second layers connected together at the opposite edges; a plurality of transverse seals extending from the opposite edge to within a predetermined distance from the inflation edge, wherein the connection at the opposite edges and said transverse seals form a plurality of adjacent inflatable pouches; a plurality of inflation edge lines of perforations through the first and second elongated layers that extend inward from the inflation edges; a plurality of opposite edge lines of perforations through the first and second elongated layers that extend inward from the opposite edges; and a plurality of gap forming lines extending between the inflation edge lines of perforations and the opposite edge lines of perforations, wherein the inflation edge lines of perforations, the opposite edge lines of perforations, and the gap forming lines delineate side edges of adjacent pouches, wherein the web is configured such that inflation of the web causes the first layer to separate from the second layer along the side edges of the pouches, wherein the gap forming lines are configured such that inflation of the pouches also causes said web to separate along the gap forming lines such that portions of said side edges of adjacent pouches delineated by the gap forming lines move away from one another and wherein said inflation edge lines of perforations are configured such that inflation of the pouches leaves the inflation edge perforations intact.
