Perforated release film is a general purpose composite release film suitable for use at temperatures up to 120°C.
This release film is used when vacuum bagging hand-layup laminates. The film offers excellent release from a wide range of resin systems including epoxy, polyester and vinylester. Its perforations provide the ideal restriction to resin flow between the wet laminate and the breather/soaker layer, allowing surplus resin to be drawn out of the laminate without excessive bleed-off of the resin.
Most commonly used when vacuum bagging a wet layup laminate, peel ply would be placed against the wet laminate, followed by the Perforated Release Film, followed by a breather/soaker layer (so absorb excess resin squeezed from the laminate), enclosed within vacuum bagging film.
