The screw and the cylinder of SJ-PP type automatic or manual PP plastic strapping band making machine adopt excellent quality alloy steel through nitrogenization treatment and has the advantages of long life for use. Good abrasion resistant and high output of extruding. With the advantages of automatic temperature control, economical pwer consumption. high output and easy operating . it used PE powder which is mainly I& II grade recycling material as its main raw material. During the process of producing the granules needn't to be dried or mixed and directly use mineral poweder instead of expensive master batch to produce automatic strapping bagnd, Which can improve the qulity of the products and rduce the production cost of the collocated printing device to a great extent.
