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
power 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 powder instead of expensive master batch to
produce automatic strapping band, Which can improve the
quality of the products and reduce the production cost of
the collocated printing device to a great extent.
