Reinforced sandwich corrugated board obtained national patent

The reinforced sandwich corrugated board (“Wazhongwa”) developed by Guangxi Guilin Chenguang Paper Products Co., Ltd., and the shockproof and pressure-resistant packaging box made of this board, and the reinforced structural packaging container, have recently been Obtained the national patent certificate. This is another new type of packaging material after honeycomb paperboard, heavy-duty corrugated cardboard, and 3A heavy-duty corrugated cardboard.
"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. After testing, compared with ordinary corrugated cardboard, "Wazizhongwa" many physical indicators more than a few times or even more than ten times. At the same time, the "Wazhongwa" has a compressive and shock-proof performance close to that of wood, and its cushioning performance is better than that of wood. Because "Watakawa" is a full-paper packaging material, it also retains the advantages of good corrugated board resistance, ease of manufacture, printability, light weight, good cushioning properties, and recyclability. It can effectively replace wood materials and EPS cushioning material.
