10 u2032 includes an easily breakable line of perforations 29 between the spaced lines of perforations 24 26 the force needed to rupture or separate the line of perforations 29 is less than the force needed to separate the perforations 24 26 extending inward of the web edges 18 20 each pair of perforations 24 26 and associated more easily breakable line of perforations 29 divide the transverse seal 22 into two transverse sections as a pouch 12 is inflated the line of perforation 29 begins to rupture or separate leading to the development of a gap 13 between the produced dunnage units 12 u2032 see fig3 once the pouch 12 is fully inflated the line of perforations 29 is fully or nearly fully ruptured however the perforations 24 26 at the edges remain intact these perforations 24 26 are ruptured or separated when a worker or automated process mechanically separates the perforations 24 26 fig5 illustrates another embodiment of the web 10 u2033 in this embodiment the gap forming area 28 comprises an elongated cut 31 through both layers of material 14 16 the cut 31 extends between each associated pair of lines of perforations 24 26 in the embodiment illustrated by fig5 pairs 30 of transverse seals 22 u2032 extend from.
