ABSTRACT:
An improved process of manufacturing a plastic helical net is disclosed. The process begins by co-extruding two or more plastic materials characterized by having different properties of contraction and orientation to form a bi-component sheet. Holes or impressions are formed in the sheet at regular intervals as by embossing, drawing, punching or slitting, and then the sheet is oriented, as by stretching, well below the melt temperature of the materials, and then releasing.
