Poly Backer is a clear, low temperature plastic release film. With a meltpoint of 120 centigrade, it is designed for use in prepreg processing up to 120centigrade and will release from all resin system. Two type of Backer, perforated film and non-perforated film.Non-perforated film is used between tool and resin to prevent the resin stickto the tool. Perforated film can be applied in between prepreg and breatherfabric to prevent two resin from sticking. The thickness of the film is 0.16mm.
Excellent stretching and strength
Quiet and easy to use
Excellent cling
Superior puncture resistance
All the products are available in various sizes and thickness according to the end use requirements.
