Three Layer Co-Extrusion Film Blowing Machine
Three Layer Co-Extrusion FilmBlowing Machine
With improving living standards, three layer co-extrusion film blowingmachine is increasingly widely used. Take the application of film for anexample, three layer co-extrusion film accounts for a large part of market infood and cosmetic packaging. In order to fulfill the needs of customers, 3SJ-G threelayer co-extrusion film blowing machine is developed.
Our three layerco-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 andproperty. Advanced extruder whose screw L/D is 28:1 is installed toimprove production output and achieve excellent plasticizing effect. Hardnessof screw and feeding cylinder is improved so that our equipment can work athigh temperature. 
Besides,variable frequency electric motor is installed to keep extruder and screwworking 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 installedin this machine. Our three layer co-extrusion film blowing machine usesmaterials like LDPE, HDPE, LLDPE. And It is widelyused to manufacture composite film base material, liquid film, protective film,cable film, macromolecule adhensive film,multifunctional industrial film products, can better meet operationalrequirements of high accuracy and high speed color printing, composite andpainting products.
