Calender method is the main film forming process of PVC of three-layer co-extrusion blowing machine

Three-tier co-extrusion blown film machine, compared with similar equipment has a higher yield, plasticizing good products, low energy consumption, the advantages of simple operation, completely solve the film falbala and winding size top problem, make the product quality on a new step.

The film produced has high transparency, puncture resistance, high toughness, low temperature heat, good composite fastness and anti-curl. This kind of film can be widely used in heavy and heavy packaging due to its good barrier, fresh preservation, moisture prevention, frost prevention, oxygen isolation and oil resistance. Such as a variety of fresh fruit, meat food, pickles, fresh milk, liquid drinks, medical supplies.

In the process of heating the equipment for 3 to 4 hours, check whether each heating part is normal and whether the voltmeter pointer is normal. Starts, the host at a speed of 15 to 20 RPM boot, observing the situation of material plastication, the pressure of the host, current is normal, it is forbidden to heat to forcibly boot (such as heating is not enough to lead to mold dislocation and film thickness).

Before stopping, use pure copper scraper to clean the deposit, clean the film mouth with paraffin, and reduce the effect of precipitate on the film bubble. The multi-layer co-extrusion film blowing machine is also divided into the following categories, such as two-layer co-extrusion film blowing machine, three-layer co-extrusion film blowing machine, five-layer co-extrusion film blowing machine and seven-layer co-extrusion film blowing machine. In addition, calender is the main film forming process of PVC.

The three-layer co-extrusion blowing machine is designed to absorb the advanced technology of similar products at home and abroad. Suitable for all kinds of high - grade film packaging. This kind of film can be widely used in heavy and heavy packaging due to its good barrier, fresh preservation, moisture prevention, frost prevention, oxygen isolation and oil resistance. Such as a variety of fresh fruit, meat food, pickles, fresh milk, liquid drinks, medical supplies.
