Have you ever seen a steel rule die on a clear base? We create many dies on Lexan/polycarbonate bases. The clear base is needed for die cutting expensive material such as leather or expensive gasket material on hand fed die cutters. Because you can hand place the die on the material, there is very little waste. It can also be used to register to print on small jobs. These dies are more expensive since lexan is 15x more expensive than wood. The lexan must also be hand-jigged with a saw due to its hardness.It is not a material that can be laser cut. If you have an application that may fit, give us a call at A&A Die.
