PE bule Film

Poly Backer is a clear, low temperature pleaserealase film. With a melt point of 120 centigrade, it is designed for use inpregreg procesing up to 120 centigrade and will relaes from all resin system.

Two type of Poly Backer, perforated filmand non-perforated film. Non-perforated film is used between tool and resin toprevent the resin stick to the tool. Perforated film can be applied in betweenpregreg and breather fabric to prevent two resin from sticking. The thicknessof the film is 0.16mm
