Abstract
A method for producing inflated dunnage on the site of use, comprising providing, in web form, a plurality of preformed plastic bags, each of the bags comprising two plastic sheets in facing relationship and sealed along three edges with one edge remaining open. Air is blown toward each of the open edges in sequence, causing each bag to inflate, and the open edge of each inflated bag is sealed, the bag being empty except for the air. A plurality of sealed inflated bags is separated from the web and placed in a carton to serve as dunnage. The bags have a slip resistant outer surface which causes the bags to interlock in the carton and better protect objects therein from shock.
