ABSTRACT:
A packaging material is formed from a pair of juxtaposed sheets. The material includes a plurality of continuous passages formed between the sheets and extending between two of its edges. Each of said passages is delimited by a pair of spaced partitions, at least one of which follows a sinuous path between the edges. The passages are inflatable by admission of air to provide a shock absorbing facility.
