The function of the casting film machine is to divert and recombine the melt, further soften and mix it, in order to improve the dispersion and uniformity of the mixing system. Adjust the appropriate melting pressure, remove gas from the material, increase the density of the melt, and prevent the formation of pores and pores in the film. Alternatively, in production, there are performance requirements for the screen changer. The cast film product has multiple functions, high requirements, and strict processing conditions. Only a screen changer can meet the needs of production. In fact, it can remain unchanged at room temperature, but it will shrink after heating. The barrel and screw are made of alloy steel and undergo nitriding treatment. The casting film machine has good hardness and corrosion resistance. The auxiliary machine is equipped with a working platform for easy operation and is equipped with a fixed bubble ring. Especially when the equipment is working, the winding device adopts double winding and cutting, and its power adopts a torque motor, which can maintain appropriate tension, tidy winding, and convenient roll changing. The casting film machine is now mainly used for blowing PLA, PBAT, PVA water-soluble biodegradable plastic films. Widely used in liquid packaging, printing lamination, clothing and textile packaging, industrial product packaging, etc. Compared to one layer, the bag is stronger and comes in two colors. In fact, the film produced by the casting film machine has excellent heat sealing performance and excellent transparency during operation, making it one of the main packaging composite substrates. Used for producing high-temperature cooking films, vacuum aluminum plating films, etc., the market prospects are very broad. Moreover, in recent years, with the development of domestic casting machine production equipment, some technical indicators have reached international advanced levels. Therefore, the threshold for entering production is getting lower and lower. As a result, some enterprises are rushing to introduce casting film production lines in order to achieve one-step success, pursuing higher quality while disregarding market demand and investment returns. This can cause huge resource waste. Therefore, the casting film machine is widely used for packaging textiles, flowers, food, and daily necessities.
