Release Film Perforated

Price shown is per linear metre. The release film is 1.22m wide.

Release film is used to create a barrier between the composite (be it wet lay, infusion or pre-preg) and the bagging film that will easily separate from the composite. The release film also allows the vacuum bag to move more easily over the surface of the part, making the bag less prone to 'bridging' in corners.

Please note that there are many different types of release film available, some of which are available very cheaply indeed. This release film is one of the best available and is specifically designed to be very stretchable, making it much less prone to bridging itself. This is the only release film we use ourselves and so is the release film we recommend and supply to our customers.

Perforated release film is used when vacuum bagging a wet-laid composite. The perforations in this film are at P3 intervals which means there are tiny holes aproximately every 8mm. These holes allow a controlled amount of resin to be squeezed out of the composite, through the peel-ply, and through these holes into the breather cloth, reducing the resin content and so improving the strength-to-weight ratio of the finished part.

For pre-preg vacuum bagging a none-perforated release film is normally used instead because there will not be any excess resin to remove from the composite. None-perforated release film can also be used in vacuum bagging of a wet-laid composite if you intend to perforate it yourself.

Owing to the low price of vacuum bagging consumables, we have a minimum order quanitity of 5 metres of this material. Please enter a quanity of at least 5 in the Qty box when ordering. Volume discounts apply.
