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 for each bag cavity. At least one air flow sealing line extends inward into the bag cavity. An air flow channel is formed between the second and third bag layers. An air pocket is located in the air channel layer for each bag cavity. An air bag opening is formed through the second bag layer in the air pocket. Air flows through the air flow channel into the air pocket and through the air bag opening to inflate each bag cavity. |
