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. Paper-based 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.
In the large-scale packaging of cabinet-type air conditioners, refrigerators, and color TV sets, the use of a new environmentally-friendly packaging material, "Watakawa," can effectively achieve the effect of green packaging.
"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, many physical indicators have exceeded several times or 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 faces form a powerful matrix of pipe piles, which can effectively prevent damage to the contents of the box. Especially for larger, lighter weight, more fragile, and less afraid of pressure products, it can better reflect its superiority. Because "Watakawa" is a full-paper packaging material, it also retains the advantages of good corrugated board resistance, easy fabrication, 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 can effectively replace the wood material and the EPS cushioning material.
The biggest feature of the "Wa Zhong Wa" made of packing box is to use the "Wa Zhong Wa" paperboard sandwich as the corrugated space, and use the plug (the wood material for the wood, bamboo, plastic or paper tube) to connect with the bottomless box. , It is more convenient for the packing and picking process of heavy items. At the same time, the use of "Watakawa" cardboard due to its good flat pressure and bending strength, if it is connected with the paper tube made of leg brackets, it is convenient for mechanized handling operations. "Wazhongwa" packing box is compact, seamless, nail-free, foldable and easy to mold, not only reduces the overall packaging cost, but also improves the aesthetics and integrity of the packaging box. It will be a relatively large-scale household appliances, electromechanical equipment, etc. Ideal packaging container.
