Abstract
End user filled protective packaging with self-sealing air bubbles includes a bubble layer, a valve layer and a valve cover layer. A plurality of bubble cell patterns are formed on the bubble layer with adhesive, glue or heat sealing. The valve layer is attached to bubble layer. A plurality of check valves are formed on the valve layer with adhesive, glue or heat sealing. An air opening is formed through each one of the plurality of check valves to inflate the plurality of bubble cells. The valve cover layer is attached to the valve layer. A row with at least one bubble cell is filled with air by applying a source of air at an entrance of the check valve. Inflation of the at least one bubble cell causes the valve layer and valve cover layer to contact each other to seal the check valve.
