Abstract
An elongate flattened thermoplastic tube has an inflation edge and an opposite edge. The tube includes spaced transverse seals that define sides of pouches. The tube includes lines of weakness that allow adjacent dunnage units to be separated. A frangible line of connection is disposed in one two superposed layers of the tube proximate to the inflation edge. This frangible connection may be broken to permit inflation of the inflatable pouches.
Claims5
1-22. (canceled)
A web for forming dunnage units, comprising:
- a) a first elongated layer;
- b) a second elongated layer superposed over the first elongated layer, the first and second layers connected together at an inflation edge;
- c) a frangible line of connection disposed in one of the first and second elongated layers, the frangible line of connection being substantially parallel to the inflation edge and offset from the inflation edge by a first distance;
- d) a plurality of transverse seals extending to a seal termination point that is a second distance from the inflation edge, wherein said second distance is greater than said first distance;
- and
- e) 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.
