Abstract
An inflatable, conformable, cushioning, packaging product (11) comprises a plurality of individual inflatable strips (21) of multiple bubble cushioning structures. Each individual inflatable strip (21) has a plurality of bubble chambers (23) with each bubble chamber (23) interconnected to an adjacent bubble chamber (23) by an interconnecting passageways (25) which is smaller in size and internal volume than the bubble chambers (23), but which is sufficiently large to enable air volume and pressure in one inflated bubble chamber (23) to be transmitted to adjacent bubble chambers (23) for distributing a shock load on one bubble chamber (23) along the entire length of the individual inflatable strip (21) of interconnected bubble chambers (23). Each individual inflatable strip (21) is defined between two laterally extending spaced apart peripheral seal lines (43) which have an undulating configuration free of corner shapes which could concentrated stresses.
