The film manufacturer will analyze the molding process of polyethylene film for you.

In the development of agriculture, the role of mulch is more important. Whether it is greenhouse crops or ordinary crops, mulch film has always been a good surface insulation material. With the development of agricultural economy, the consumption of mulch film is also increasing. So how is the mulch made? Today, the film manufacturer Qingzhou Luyi Plastic Factory will analyze the molding process of polyethylene film for you.
Polyethylene film is a kind of film for covering the growth of crops. Its function is to keep warm, retain water and prevent the loss of fertilizer, which is convenient for crop yield increase. In order to meet the needs of different crops, the film can be made into black, red, white, blue and other colors. If the potato is covered with black film, it will increase production and increase temperature; the red film is suitable for the ground cover of cotton growth; the apple orchard floor is covered with silver gray reflective film, the color of the fruit is good, mature early, and the effect of removing mites.
There is also a photodegradable film formed by adding a photodegrading agent to polyethylene in the mulch film. The mulch film degrades into fragments under the action of light, reducing the environmental pollution of the film.
The forming process of polyethylene film includes:
1. Raw material for film extrusion blow molding a. The polyethylene resin for ordinary film has a density of 0.92 g/cm3 and a melt flow rate (MFR) of about 2 g/10 min.
b. Add 3%-5% color masterbatch or a small amount of colorant to the polyethylene resin for colored film.
c. Photodegradable mulch film is a photodegradation agent and other additives added to the polyethylene resin.
2. Selection of equipment and process parameters. Extrusion blow molded polyethylene film, equipment and process parameters are selected and used in the same equipment and process parameters as ordinary polyethylene blow molded film. The polyethylene film extrusion blow molding process differs from the ordinary polyethylene film extrusion blow molding process in that the blow ratio of the bubble is slightly larger, the finished product is cut at the folded portion, and then separately wound into bundle.
