which the dunnage units is designed to rupture in the embodiment illustrated by fig3 the gap forming area 28 produces a gap 13 between adjacent pouches upon inflation the gap allows foreshortening of the connected pouch sides and thereby reduces the undesirable stresses that are introduced during inflation as compared with prior art webs in addition the web with a gap 13 facilitates fuller inflation of each pouch the gap 13 maintains the inflation opening substantially free of wrinkles as the inflation opening is sealed to convert the inflated pouches to a dunnage units the illustrated web 10 is constructed from a heat sealable plastic film such as polyethylene the web 10 is designed to accommodate a process for inflating each pouch 12 in the web to create a row or ladder 11 of dunnage units 12 u2032 the gap forming area 28 creates a gap 13 between dunnage units 12 u2032 which facilitate a efficient and effective process for separating adjacent dunnage units 12 u2032 in the row or ladder 11 in the example illustrated by fig4 the gap forming area 28 defined by the web 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.
