Description
This production line adopts extrusion casting unidirectional horizontal stretching process to process into PE breathable film. Based on many years of casting equipment manufacturing and customer use actual operation, our company has continuously accumulated experience and continuously updated and transformed with foreign advanced technology. The cast film production unit with high speed, high efficiency, high automation, energy saving, material saving, easy operation, long machine life, etc. is in line with foreign technology.

Application
This unit uses LDPE, LLDPE, HDPE, etc. as the main raw materials to produce cast air-permeable film, PE film, embossed film, matting film and other products. Among the varieties of plastic films, breathable films have been widely used in the sanitation and pharmaceutical industries. Products produced with them involve baby diapers, adult incontinence pants, nursing products, and feminine hygiene products; medical protection products, hospital anti-allergic bedding ; Protective clothing, isolation clothing and their lining materials, etc.

Features

1.   The mechanical speed of the breathable film casting machine can reach 300m/min, which is a rare high-speed cast film line in China, which greatly increases the production capacity.(Equipment acceptance speed 30g 180m / min; 16-17g 250m / min)

2.   The new barrel heat conduction oil heating and water cooling method, when the screw is running at high speed, by adjusting the temperature and flow rate of the oil, the large amount of heat generated by the friction between the screw and the barrel is taken from the high temperature zone to the low temperature zone, thereby avoiding the problem of local high temperature. Ensure the balance of the surface temperature of the barrel, and save energy and consumption.

3.   Online granulation system, during the production process, the film edge material can be directly recycled to the granulation system online, recycling, saving raw materials, and greatly reducing production costs.

4.   The cooling roll adopts the special design of sandwich spiral flow channel, and the inner tank cooling system is excellent, ensuring that the roll surface of high-speed production is cooled in place, and the film cooling and shaping effect under high-speed is good;All shafts and rollers have undergone a 300-meter dynamic balance treatment. The rollers are of good quality, less pulsation and uniform temperature, which makes the film quality better.
