The lab blown film machine melts and melts plastic particles into a film. There are many kinds of film blowing machines, such as PE, POF and so on.
The new material is blown out with new particles, the color is called, clean, and the bag is stretched well. Some people also use recycled plastic bags to make particles. These particles are generally called old materials. When they are made into particles, they are usually gray. When making bags, they usually add pigments, making the bags unevenly colored, brittle and fragile. The price is also lower.
The lab blown film machine produces a film suitable for a variety of high-grade film packaging. The film is widely used for light and heavy packaging because of its good barrier property, preservation, moisture resistance, frost resistance, oxygen barrier and oil resistance. Such as a variety of fresh fruit, meat food, pickles, fresh milk, liquid beverages, medical supplies and so on.
The composition of the film blowing machine consists of the motor motor, the screw and the barrel, the die head, the inverter inverter, the v plate, the opposite wheel, the smoothing wheel, the opposite wheel, and the winding wind.
Raw material LLDPE and LDPE temperature is 160–180 degrees HDPE temperature is 210-230 degrees The most important thing for blown film machine operation is three factors: temperature (machine temperature, indoor temperature), two spirals, three cooling system
Classification of PE blown film machine
PE blown film machine classification is high and low pressure blown film machine can be divided into single head blown film machine, double head blown film machine, according to the configuration is divided into double winding blown film machine, rotary head blown film machine and then PP blown film Machine and PP blown film machine are divided into two layers of PP film blowing machine, three-layer co-extruded PP film blowing machine, and composite film blowing machine. It is divided into two layers: co-extrusion film blowing machine and three-layer co-extrusion film blowing machine. , PA film blowing machine, PVC film blowing machine, POF film blowing machine, self-sealing bag blowing machine, PP tear film blowing machine, etc.
What does PE material mean?
PE material is polyethylene, which is the largest variety of plastic materials. It is a polymer material synthesized from polyethylene. There are basically two types: low density polyethylene LDPE; high density polyethylene HDPE. PE materials are classified into five grades according to internationally uniform standards: PE32, PE40, PE63, PE80 and PE100. PE is widely used, and is divided into high-density, low-density and linear PE. The most common applications are made of various plastic films and plastic sheets. PE pipes are medium density polyethylene pipes and high density polyethylene pipes. According to the wall thickness, it is divided into SDR11 and SDR17.6 series. The former is suitable for conveying gaseous artificial gas, natural gas, and liquefied petroleum gas, and the latter is mainly used for conveying natural gas.
Compared with steel pipes, the construction process is simple, has certain flexibility, and more importantly, it is not used for anti-corrosion treatment, which will save a lot of processes. Disadvantages are not as good as steel pipes. Special attention is paid to the safe spacing of thermal heating during construction, and it should not be exposed to the sunlight in the air, and it is sensitive to chemicals and prevents leakage of sewage pipes.
