TEFLON® FEP fluorocarbon film   TEFLON® FEP fluorocarbon film DuPont FEP film is a transparent, thermoplastic film that can be heat sealed, thermoformed, vacuum formed, heat bonded, welded, metalized, laminated-combined with dozens of other materials, and can also be used as an excellent hot-melt adhesive. This wide variety of fabrication possibilities combines with the following important properties to offer a unique balance of capabilities not available in any other plastic film. Superior antistick properties make it an ideal release film for many applications. A cementable type with an invisible surface treatment is available for bonding to none or both sides with adhesives. This versatility is augmented by the superior properties of a true melt-processible fluorocarbon and by the wide choice of product dimensions available from DuPont. TEFLON FEP
