The light belt core is made of cotton, nylon, polyester and other fabrics. There can be a covering layer or no covering layer outside the belt core. The covering layer types are divided into rubber type (including rubber and plastic type) and plastic type. The surface of the light bag can be smooth Yes, it can also have various patterns of deep and shallow patterns or horizontal strips, partitions and corrugated ribs. The transmission surface can also have longitudinal positioning strips. The light belt can be wrapped or cut.
