Abstract: The present invention relates to plastic extruded strapping and its processing techniques. More particularly, it is concerned with polyester extruded strapping of high tensile strength and low elongation at break to replace steel strapping. Although not limited thereto, this invention is of primary importance in connection with the technique of crystallization and orientation of polyester predominantly in one direction in the making of strap characterized by two-step stretching. Furthermore, this invention is related to the design of a multi-purpose extrusion line for the processing of strap of various polymeric materials.
