With improving living standards, three layer co-extrusion film blowing machine is increasingly widely used. Take the application of film for an example, three layer co-extrusion film accounts for a large part of market in food and cosmetic packaging. In order to fulfill the needs of customers, 3SJ-G three layer co-extrusion film blowing machine is developed.
Our three layer co-extrusion film blowing machine consists of loading material system, extruder, cooling system, traction system and rolling system. Because an extruder imposes an important effect on film quality and property. Advanced extruder whose screw L/D is 28:1 is installed to improve production output and achieve excellent plasticizing effect. Hardness of screw and feeding cylinder is improved so that our equipment can work at high temperature.
Besides, variable frequency electric motor is installed to keep extruder and screw working steadily, thus ensuring a steady feeding of material. This 3-layer film blowing machine adopts A+B+C co-extrusion and can achieve even film thickness and film smoothness. And rotary die is installed in this machine. Our three layer co-extrusion film blowing machine uses materials like LDPE, HDPE, LLDPE. And It is widely used to manufacture composite film base material, liquid film, protective film, cable film, macromolecule adhensive film, multifunctional industrial film products, can better meet operational requirements of high accuracy and high speed color printing, composite and painting products.
