POF Shrinkable Film Co-extrusion Machine

POF products are extruded into film with LDPE, MLDPE and PP as material, then, going through second heating and two-way stretching, finally, folding and slitting. POF film’s full name is POF environment-friendly three-layer (five-layer) co-extruded polyolefin two-way stretching heat shrinkable film. It is advanced packaging product at home and abroad currently. This film has features of: high tenacity, high tensile strength, puncture resistance, high transparency, high shrinkage rate, thus accords with environmental protection requirement of the international market. Its application almost covers all daily necessities, industrial products, and agricultural products. As long as packaging is needed, POF film is much more competitive. Technical and economic indexes Features: 1.Special extruding technology suitable for POF material: special extruding system designed by special CAD system. It has features of high torque, low shear, large extruding quantity, and high plasticizing. 2.Special extrusion mould technology for POF: special tacked multi-layer co-extruding mould is designed according to POF’s physical performance index. New technology of mixing in the mould is adopted so that there is little resistance for material flow and even thickness. 3.special POF mold automatic control technology 4.Special far infrared heating oven technology for POF: special PID control system with balanced heating. 5.Special zigzag row roll technology: low resistance and small row space. 6.Special pulling winding rotary technology: high pulling force, smooth rotation and tidy winding, to ensure product quality. 7.Special POF production technology and special PLC electrical control technology for POF, easy to operate and reliable. 8.Equipped with "international advanced film thickness gauge”to achieve real-time monitor of film uniformity. 9.Equipped with capacitive probe or America NDC gamma reflective probe.
