Abstract
A system and method for forming a vacuum bag packaging material into a desired shape includes subjecting the exterior of the packaging material to a vacuum to expand the packaging material. The expanded packaging material is then pressed into or against a forming device. Expanding the packaging material renders a filler material inside a sealed packaging membrane free flowing, such that the packaging material can assume the shape of the forming device during the pressing operation. When the vacuum is removed, the membrane recompresses upon the filler material and renders it non-free flowing such that the formed packaging material maintains the formed shape during ordinary handling.
