PET/PP Strap Production Line
PET strap, also known as plastic steel band, which is used in place of steel on the world of a new environmentally friendly packaging materials. It has the tensile strength of steel belt, has good ductility and impact resistance, is not easy to break, and has small extension.
It have been widely used in the steel industry, chemical fiber industry, aluminum ingots, paper, brick kiln.industry, screw industry, tobacco industry, electronics, texties and wood, etc.; is replaced by a new high strength steel strapping, is the world' s most widely used for steel products.
The flakes are dried bylow dew point air to reduce the moisture to less than 150 ppm
Extruder/melt Metering Pump/melt Filter
a) Large melt impurity filter,reduce times of screen change
b) Keep melt clean, increasethe strap quality (surface gloss, tension)
c)Stabilize melt pressure intomold
d)To ensure consistent of strap specification, thickness and width
Cooling the PET strap from the mould,circulating cooling water
Preheat in the heat oven before stretcher
Stretch strap and increase the strength
Two side of strap embossing, increase the friction
Setting and Cooling Return Air Box
setting the strap with heating and cooling (patent design)
Automatic winding, weighting and metering
