The definition of blown film machine, plastic film blowing machine is melted and blow into a plastic particles heating film. Plastic film blowing machine and a lot of kinds, there is PE, POF, and so on. Blow out the new particle is a new material, colour and lustre are, according to clean, good tensile bag. Also somebody made from recycled plastic bags to the particle, the particle generally called the old material, made of particles is usually gray, usually to add pigment, when it made the bag made from bags to uneven color, brittle and break easily, the price is low. Although is recycling plastic bags are generally in the process of bag making waste bags and usually in the sense of waste plastic has the very big difference. Blown film machine, blown film machine is composed by (1), (2) cylinder, (3) the head, electrical plate (4) dies, (5 v, 6 of wheel, 7) smooth round, round 2, pet-name ruby wind the nine part of the raw materials of LLDPE and LDPE temperature is 160 - - HDPE temperature is 210-180 degrees 230 degrees of blown film machine work is one of the most important three factors (a temperature The machine temperature, indoor temperature) Blown film machine two helix three cooling system is the application of plastic film blowing machine production plastic film is suitable for all kinds of top grade film packaging. This kind of membrane due to its good barrier property, keeping fresh, well protected against dampness, frost proof, oxygen insulation, oil resistant, can be widely used in light and heavy package. Such as all kinds of fresh fruit, meat, pickles, fresh milk, liquid beverage, medical supplies, etc. But it is not made from waste plastic raw materials, raw material is made from plastic particles. The correct way of using the blown film machine 1, check the temperature control in good condition, heating appliances in good condition, pay attention to timely adjust the heating temperature at various points in the range of indicators. 2, check the drawing speed, control the film thickness. 3, observation adjustment film thickness uniform, folding size up to the standard. 4, check the air cylinder pressure storage, not too high, but shall have the standby pressure. 5, check control raw material and mixing ratio. 6, check the raw materials have impurities, especially immediately with the iron mixed with magnetic inspection. 7, check the reduction space and air compressor cylinder lubricating oil. 8, regularly check the running motor temperature rise and mechanical transmission.
