Abstract
The present invention provides an integral net having a lattice of polymeric material defined by holes traversing the integral net from one surface to the other. The present invention also provides a method for producing an embossed sheet of polymeric material by first contacting a billet of polymeric material with an embossing tool having a plurality of protrusions whereby the embossing tool impresses indentations into the billet to a given depth. Subsequently, the method involves skiving the embossed billet. By this method, an embossed sheet of the polymeric material is removed from the billet, which embossed sheet can be an integral net.
