The PE breathable film production line will melt and plasticize the dried resin raw materials through an extruder, then pass through filters and connecting pipes, enter the casting die head, and then squeeze them out through the die nozzle.

Then the thin film will stick tightly to the cold roll, and the thickness will be measured using a thickness gauge, including the preheating and stretching rolls to start directional stretching. The cooling process will come to an end, and after cooling, some excess material will be cut off. Then, it will be rolled up through an automatic winding device, and finally cut to obtain the corresponding thin film product.

Basically, the production principle of the PE breathable film production line is like this, but for some special needs, the production process may also change, so this needs to be discussed on a case by case basis.
