Abstract

An inflatable web is disclosed. The web includes a first and second film ply sealed together. The transverse seals define first and second inflatable chambers. The web defines a separation region extending at least partially between the first and second inflatable chambers in a substantially transverse direction across the web and configured to facilitate separation of the first and second inflatable chambers. The separation region includes a tear initiation feature that facilitates tearing of the web to separate the inflatable chambers. The separation region includes a tear propagation line including a first plurality of perforations perforation is separated from an adjacent perforation by a land having a first transverse length. A tear initiation feature includes a second plurality of perforations, each perforation separated from an adjacent perforation by a land having a second transverse length, where the first transverse length is longer than the second transverse length.
