Co extrusion ABA blown film machine, whether the production of HDPE materials or LDPE and LLDPE materials, has its unique characteristics. The physical strength of the film is improved by multi layer co extrusion, and the inner and outer layers of a host machine can be used to reduce the configuration of a host machine. Meanwhile, the purpose of reducing the cost, saving energy and reducing consumption is achieved.
In the process of blowing film, the dew point has a certain influence on the film properties. If the dew point is high, is located above the blow after the bubble, the film is blown in liquid, blowing only the film thin film blowing machine manufacturer, printing machine, and then by molecular orientation, blown film properties close to the cast film, film blowing machine, on the contrary, if the dew point is relatively low, while inflation is in the solid state, this time in the high elastic state, plastic film blowing machine manufacturer, blowing like transverse tensile, the molecular orientation effect, thus the performance of blown film close to the oriented film.
Film blowing machine production process is firstly added polyethylene particles drying hopper, then particles by their own weight from the hopper into the screw thread, when the screw and the oblique edge contact, the rotation of the face of the plastic face aslant vertical thrust and aslant, the particle goes forward.
In the push process, the friction between the plastic and the screw and the plastic and the cylinder, as well as the collision and friction between the particles, and the external heating of the cylinder to melt the plastic. Because of the development of film blowing machine reaching high-end technology, relatively on the market a lot of high consumption and low efficiency of mechanical products is gradually reduced, plastic film blowing machine industry is to keep up with the period criterion, super energy-saving emission reduction step, plastic film blowing machine machinery manufacturing industry, the application of high-tech, new type of film blowing machine production meets the diverse needs of the market.
