Today this article focuses on the vacuum belt manufactured by Yonghangbelt, we know that the vacuum belt is mainly used in VFFS vertical packaging machine, filling sealing machine and other food packaging equipment on the vacuum pulling film equipment, in daily production use, there are often vacuum belt adsorption sealing is not strict, there is a leakage phenomenon, resulting in poor adsorption effect of the problem, and Yong Hang vacuum belt selection of virgin neoprene The vacuum belt is made of virgin neoprene, with good flexibility, anti-slip and wear resistance, good stability, not easy to break longitudinally without delamination, etc. One side of the vacuum belt is a one-piece forming tooth surface, the other side is the adsorption surface, both sides of the tooth surface has a tooth structure, the root of the tooth structure has an open groove, and the vacuum belt body has a suction hole, which can solve these problems well, and also has the following three advantages.
