The special blue cloth bonding and pressing process will not tear, detach or deform even under large tension. At the same time, the belt has high tensile strength and wear resistance. Sponge conveyor belt is widely used in labeling machine, paste box machine, toilet paper industry conveyor, precision electronic components conveyor and so on.
Product Feature:
