Fluid-forming compositions in a container attached to enclosed adjacent sheets are heated to relatively high temperatures to generate fluids (gases) that effect inflation of the sheets. Fluid rates to the enclosed space between the sheets can be regulated by the canal from the container. Inflated articles can be produced by a continuous, rather than batch-type, process.

[ What is claimed is:] [1.]1. A method for inflating at least one of two adjacent sheets, said method comprising:sealing a space between said adjacent sheets except for at least one fluid communication opening from said space;sealing a container containing a fluid-forming composition about said fluid communication opening;concurrently heating said adjacent sheets and said container to generate sufficient internal fluid pressure from said fluid-forming composition to alter a shape of at least one of said adjacent sheets.
