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.
