Waterproof and breathable film machine equipment factory: Among the plastic film varieties, breathable film machines are widely used in hygiene, medicine, construction, automotive, and sports industries. The products produced using breathable film machines include baby diapers, adult incontinence pants, nursing products, and women's hygiene products; Medical protective equipment and hospital anti allergic bedding; Protective clothing, work clothing and their lining materials; Roof protective materials and breathable waterproof materials, etc. The production equipment for cast film includes an extruder, magnetic head, air knife, cooling roller, corona treatment roller, traction roller, coiling device, trimming and recovery system. Dalian Plastic Blowing Film Machine introduces three types: extruder, head, and cooling roller.
The production process of casting CPP thin films is divided into 11 stages:
Resin extrusion melt plasticization - T-head extrusion - casting - cooling roller shaping - corona treatment - traction - coiling - storage natural shrinkage - segmentation - finished product.
Compressed air blows the casting film onto the surface of the cooling roller and tightens the cooling roller to improve the cooling effect. Further cool both sides of the film through two cold rollers. The casting film has sufficient cooling, so the production speed is 60~100m/min higher than the injection molding method, which may be 3-4 times faster than the production speed of blown film.
