ABSTRACT OF THE DISCLOSURE Devices for packaging and/or cushioning products and objects, the devices including elastomeric sheets sealed together at predetermined locations to form separate and discrete chambers, or intercommunicating chambers, inflated initially partially or entirely with gas or gases which have very low diffusion rates from each chamber through the elastomeric sheets, ambient air diffusing more readily through the sheets into each inflated chamber to provide a total pressure therein which is the sum of the partial pressure of the air in the chamber and the partial pressure of the gas or gases in the chamber. Not only does the air diffusing into a chamber increase the total pressure therein above the initial inflation pressure of the gas or gases, but the air in the chamber inhibits outward diffusion of the gas or gases from the chamber or compensates for any loss of pressure caused by such outward diffusion of the gas or gases.
