Black ldpe film upto 250inches
Black ld film upto 250 inches wide in two layer like a tube if u want cut one side , the wide will be 500 inches, thikness is 20 micron to 125 micron.
Because of its advantage in aspects of the environmental protection(poison-less), installation and construction , large caliber hdpe supply pipe is the first choice for the outdoor service pipes, people lay greater important on them in the old pipe repair and urban water supply systems
This production line adopts the efficient single-screw extruders with specially designed shielded type bmscews in order to ensure the thorough meltiog of the matter, thus vigorously enhances the extruxion volume.
The die adapter utillzes the lately designed basket type nose or the spiral divided hand-piece, it may produce the double-ply anti-ageing environmental protection model buried water-supply pipelines
Planet cutting, section smoothing, chamfered standardization, dust-collecting device may fulfill the non-scraps cutting
