1. This unit is suitable for plastic casting film. The unit adopts single screw extrusion, and the produced film can achieve the effect of sticking on both sides; If twin-screw and double-layer composite machine heads are used, and different formulas are used, the produced film can achieve adhesion on one side or both sides, and is widely used in fastening packaging such as building materials, hardware accessories, paper mills, glass bottle factories, express delivery companies, pallet packaging, export packaging, etc.

2. Both the screw and the barrel are made of 38CrMOALA alloy steel, which has undergone nitriding treatment and precision machining.

3. The cooling device adopts circulating water cooling, which has a good cooling effect and thus improves the transparency of the film.

4. The winding device adopts friction type winding and is equipped with edge cutting and trimming devices to make the wound film more neat.
