Information

       PET strapping is a widely used plastic environmental protection strapping.They are transparent in appearance and opaque after adding adhesion promoters. The surface is flat or has prismatic patterns. Widely used in wood industry, paper industry, steel, aluminum ingot, steel pipe, glass, building materials, ceramics, electrical appliances, metal products, cotton tape and other industries. In the process of producing PET strapping, what are the temperature requirements?

PET strapping

       The temperature of the body of the PET strapping extruder needs to be determined according to the raw materials. The temperature of the machine head is generally about 510℃ higher than that of the machine. If the temperature of the machine head is too high, the raw materials are easily decomposed and have pores. Therefore, the temperature of the machine head should be strictly controlled within the specified temperature. The temperature of the strap extruded from the die is relatively high. In order to cool the strap slowly and prevent internal stress and warping, the three rollers of the three-roll calender should be heated and equipped with a temperature control device. The heating medium includes steam, oil and electric heating.

        If the temperature of the roller is too low, the belt is not easy to stick to the surface of the roller, causing spots, dull surface, poor transparency and small wrinkles. The surface temperature of the roller should be high enough to make the molten material completely adhere to the surface of the roller, but too high will cause the belt to stick to the roller and cause horizontal stripes on the surface.

The PET strapping tape uses high-quality polymer as its raw material and has excellent weather resistance. It maintains good dimensional stability between -50°C and 100°C, and has a melting point of 260°C. Not only is it resistant to high temperature and humidity, but unlike steel belts that are susceptible to rust and lose their tensile properties, the strength of the bale is reduced.
