China's PVC plastic box industry is mainly concentrated in the southeast coast and the Pearl River Delta area. Foshan is China's largest PVC film production base. Since the formation of an independent industrial sector in the late 1950s, China's PVC film industry has come half a century. There are nearly 400 PVC film makers above the scale, and 200 large and medium-sized enterprises. At the same time, China's PET film manufacturing capacity has reached the world's Lead level. At present, the PVC film manufacturers use sieves to make the PVC resin powder uniform in particle size and easy to operate: large particles, high plasticizing temperature, long time, more plasticizer absorption time, small particles, absorption The time required for the plasticizer is short, the temperature required for plasticizing the PVC film is low, and the plasticizing time is short; if the particle size distribution is too wide, the plasticizing temperature and time of the PET film cannot be easily controlled. Therefore, PVC resin powder should be sieved before PVC granulation to remove excessive PVC particles.
