The reinforced sandwich corrugated paperboard (Wazhongwa) developed by Guiguang Paper Products Co., Ltd. of Guilin, Guangxi Zhuang Autonomous Region, and the shockproof and compressive packaging boxes and reinforced structural packaging containers made of this board have recently been Obtained the national patent certificate. This is another new type of packaging material following honeycomb straight, heavy-duty corrugated board, and 3A heavy-duty corrugated board.
Because of its good flat pressure and bending strength, if it is connected with the paper tube to form a leg bracket, it can also replace the water bracket, which facilitates the mechanized handling operation. “Wazhongwa†packing box is compact, seamless, nail-free, foldable and easy to mold, not only reduces the overall packaging cost by about 30%, but also improves the beauty and integrity of the packaging box. It will be large-scale household appliances, electromechanical Equipment and other environmentally friendly packaging materials and packaging containers.
"Wazhongwa" is an excellent structure with corrugated paperboard and paper tubes between two layers of plain corrugated paperboard (two-layer, three-layer, five-layer, and seven-layer). Strength of. Compared with ordinary corrugated board, a number of physical indicators exceeded several times, even more than ten times. At the same time, the compressive and shock-proof performance is close to that of the wood board, and the cushioning performance is better than that of the wood board. "Wazhongwa" due to its structural features, makes full use of the mechanics of multi-directional support, uses high-strength corrugated paperboard, is arranged by unique process deformation, and is integrated with the best mechanical structure. The six surfaces form a powerful tube pile matrix, which can effectively prevent the damage of the contents of the box, especially for the larger, lighter weight, fragile, and afraid of pressure products to better reflect its superiority. Because "Watzwa" is a full-paper packaging material, it also retains the advantages of good corrugated board resistance, ease of manufacture, printability, light weight, good cushioning performance, recyclability, etc. It can also be adjusted by adjusting the thickness of the sandwich layer. The geometry of the sandwich layer adjusts the strength and elasticity (buffering performance) of the corrugated board, and effectively replaces the wood material and the EPS cushioning material.
