Corrugated cardboard conveyor belt is developed for corrugated cardboard production lines, specifically for double facer. It has excellent performance in cardboard conveying, flat operation, even pressure distribution to the hot board, and ensuring optimal cardboard dryness. The fiber materials of various conveyor belts are both flexible and highly wear-resistant, with high basis weight ensuring excellent strength and even distribution of contact pressure in various pressure systems, thereby ensuring perfect adhesion and rapid drying of corrugated cardboard.
