4. Applications:
PET Strap Production Line is made of polyethylene glycol terephthalate and other material which is a new kind of eco-friendly packing material that take the place of Steel Strip. Through the development of new material , the cost of it goes down rapidly. Now PET Strap Production Line is used a lot in the steel industry, chemical fiber industry, aluminum industry, paper brick, ceramics, screw industry, the tobacco industry, electronics industry, textile industry and wood industry, etc. it is the new  high strength  Straps and widly used around the world which take the place of Steel Strip.

6. Competitive Advantage:

1) Raw material is dried via the CSG series drying system which is made by our company, its minus fourty degree centigrade dew point make the moisture content of the raw material no more than 40PPM possible, what’s more, it is useful for the solid phase condensation and increase sticks to the raw material;

2) After the dry system, raw material adopts the closed cycle expulsion system, no contact with the air outside, to assure the dry effect of the raw material;

3)The extruder adopts the PET special screw, the screw’s unique separation and mixing ability enable the material even plasticizing; Dosing and steady extrusion assure even length and width of the strap.

4) The mould is self designed, different standards are made to the mold; Leakage of the material is eliminated after the improvement of the melt exchanger.

5) Static casting machine replaces the early water trough to cool the facility, casting piece is cooled under the certain constant temperature, which improves the molecular longitudinal orientation, and increases the end product longitudinal strength;

6) Calefactive anneal treatment is made after the shape of the strap, to remove the stress left after the strech, this stabilizes the molecular orientation, alleviates the phenomenon/matter of depositing metamorphism;
    7) Fetching adopts double-stage winder, easy to operate.
