A Pressbalance Film is made up of ten layers of 20μm(0.0007874 in) thick, strong film, which are lightly adhered together to form one sheet. This is placed on the upper surface of the cutting plate and using a special 50mm(1.969 in) pitch cutting die a half cut is made. The number of layers of film that are cut through depend on the extent of any irregularities, and the result is a Pressbalance Sheet that reflects any unevenness of the die cutter. By removing the sections that have been cut through, a “map” showing the die cutter punch pressure of each area is created. By covering both sides of the Pressbalance sheet with a 0.4mm(0.01575 in) protection plate, it can then be used in place of your conventional protection plate. In terms of durability, the 20μm(0.0007874 in) film is manufactured with the same high-grade resin film used on the bodies of aircraft.
