New environmentally-friendly packaging material "Wa Zhongwa"

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.

With the enhancement of people’s awareness of environmental protection, more and more attention has been paid to the research and development of environmentally-friendly packaging materials. The use of paper for wood and wood and paper-based plastics are among these. Corrugated cardboard is the most commonly used paper packaging material in the market, and corrugated paperboard plays a very important role in packaging materials. In addition to its light weight, low price, easy mechanized production, and recyclability, it also has good flexural rigidity and excellent mechanical properties, and it occupies a large proportion in the field of packaging materials. In order to make better use of corrugated board, people have conducted intensive research and development on its various properties and new components.

"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 sides 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, afraid of pressure products more to reflect its superiority. Since “Watzwa” is a full-paper packaging material, it also retains the advantages of good corrugated board resistance, easy manufacture, printability, light weight, good cushioning performance, and recyclability. It can also adjust 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.
