For small medium-sized wood replacement cartons, three-layer corrugated cardboard (generally seven-layer) is generally used; heavy-duty packaging boxes can be made through automatic production lines, which are fixedly connected with wooden pallets at the bottom of the box (in recent years, paper pallets incomplete Wood combination pallet). The Kunshan carton manufacturer uses two seven-layer corrugated cardboards to be glued together to make a 14-layer overweight corrugated cardboard box, which can withstand large Ford trucks with a load of more than 7.5 tons. Among the heavy-duty packaging cartons, there are also large-scale cartons that are made into octagonal prism shapes. In addition, the bottom lid of the octagonal shallow disk are glued to form a heavy-duty packaging container after the packaging operation is completed. This avoids causing the multi-layer ultra-thick cardboard to break when the press line is folded into a box to form a right angle. This kind of large container carton in Japan contains plastic granular materials weighing 3.45 tons (the size of the box is 2.5 meters in diameter 2.3 meters in height). Pulp Molding Wholesale
