Carrier band

PC data is characterized by high mechanical strength, good transparency, good specification stability, high glass transition temperature, and good heat resistance. The mechanical strength of PS data is lower than that of PC data, so it is sometimes made into three-layer composite sheets with ABS data to trek the tensile strength of the bearing belt, and the mechanical strength of PET data is close to PC, but due to the crystallization data, the specification stability is poor.

According to the forming method of the belt:

According to the forming method of the pocket, it can be divided into two forming methods: intermittent type and continuous type. Compared with the intermittent type, the general continuous forming method has better specification stability and higher product specification accuracy. As for the intermittent forming method, it is more suitable for preparing large sized pockets.
