ABSTRACT:
An inflatable cushioning article is made from a multilayer film having a seal layer, a gas barrier layer, and a tie layer adhering the seal layer to the gas barrier layer. The cushioning article has a plurality of inflatable chambers, with each of the chambers having a plurality of cells connected in series to one another via inflation channels. Although the inflatable article can be made from relatively thin films, the article exhibits a relatively high burst pressure and can be inflated to, for example 3 psi, and withstand conditions such as 140° F. and high altitude, without film delamination, seal failure, or film rupture. Preferably, the tie layer comprises an anhydride modified polyolefin having an anhydride content of at least 150 ppm.
