Method for manufacturing an air filled structure
A method for manufacturing an air-filled structure allows for ease of manufacturing utilizing plastic/vinyl/TPU laminated/urethane coated type top and bottom exterior layers as well as an internal baffle, all of which can be heat or chemically bonded together. Most if not all of the bonds or welds required to be made can be created at the same time in a high volume manufacturing step by providing one or more internal layer(s) each with a plurality of openings or cutouts which provide an opening or window through which the internal structure/baffle can be attached directly to the top and bottom layers of the air-filled structure.
