This set of equipment is used to produce stretch film (stretch) LDPE or LLDPE (Linear Low Density Polyethylene).
1. The propeller stem and cylinder are made of 38CRMOALA alloy and treated with nitrogen. It has the advantage of corrosion resistance and durability.
2. The water cooling system should provide the best transparency effect, which will increase the productivity of the extruder.
3. The receiving equipment is equipped with a friction rewinder, and the equipment is equipped with an edge correction device to ensure quality.
