What material is used for vacuum bags? The beginning material for the vacuum pack forming process is a prepreg that contains either unidirectional ceaseless filaments or a bidirectional texture in a to some degree relieved (additionally called B-organized) thermosetting polymer, normally an epoxy What are the different materials and films used in the vacuum bagging process? The bag film layer is generally much larger than the area being bagged as extra material is required to form pleats at all of the inside corners and about the periphery of the bag as required to prevent bridging. Bag films are made of Nylon Kapton or P.V.A. (polyvinyl alcohol) materials. vacuum bagging material suppliers SR Composites - De-Comp Composites I West System Composite World
