Compared with the similar equipment, the three-layer co-extruder has the advantages of higher output, good product plasticization, low energy consumption and simple operation. It has completely solved the problems of the first class of film flanging and winding size, and made the product quality a new step. The film produced has high transparency, puncture resistance, high toughness, low temperature heat, good compound fastness and anti-curl.

Because of its good barrier, fresh, moisture-proof, frost-proof, oxygen insulation, oil resistant, can be widely used in heavy packaging. Such as a variety of fresh fruit, meat, pickles, fresh milk, liquid drinks, medical supplies. Now we will briefly introduce the three - layer coextruder operating procedures, I hope to help you.

The three-layer co-extrusion film blowing machine can adapt to different combinations of raw materials, adopts PLC full digital control system, and the automatic coil changing device is equipped with hydraulic blanking structure. The rotation device is adopted to cooperate with EPC edge tracking device. High platform flat rail friction double winding machine with vector motor and pneumatic control. Plastic particles are heated to melt and blown into thin films.

There are many kinds of film blowing machines, such as PE,POF,PVC, etc. With the new particles to blow out of the new material, color weigh, clean, the bag stretching good. Check whether the temperature control is in good condition and the heater is in good condition.

Polymer sheet co-extrusion process is a process in which several extruders are used to supply different melt streams, which are combined and co-extruded in a compound head to produce multilayer composite sheet. Can produce environmentally friendly film blowing machinery (such as water-soluble film, starch film, photodegradation film, biodegradation film, etc.). A number of domestic companies have launched plastic heavy packaging film equipment, mainly including three - layer co-extrusion blow plastic packaging film unit and five - layer co-extrusion heavy packaging film unit.
