Abstract
A plurality of self-sealing inflatable dunnage bags are formed on a continuous strip. The continuous strip includes a first bag layer, a second bag layer and an air channel layer. A bag perimeter sealing line is formed between the first and second bag layers to form a bag cavity. Two air flow sealing lines extend into the bag cavity. An air flow channel is formed between the second and air channel bag layers. One end of a cross air flow channel communications with the air flow channel and the other end communicates with a fill opening in the second bag layer. Air from an inflation pin flows into each cross air flow passage and through the fill opening to inflate the bag cavity. Inflation of the bag cavity causes the two air flow sealing lines to seal the cross air fill passage and prevent deflation of the bag cavity.
