The air tightness and strength of double grey cardboard produced by manufacturers on the market vary due to differences in the quality and grade of the cardboard. Such double grey cardboard can only be used for general paper products. For others, not only is the paper average, but the price is also low, which often results in poor wear resistance.

To improve the quality of grey cardboard, we need to consider the standard application range and performance of the product. High end grey cardboard products focus on product quality and taste, so good packaging is needed. Some high-end products can reflect their own value and art from their packaging. After improving their packaging, the utilization rate of double grey cardboard will also increase.

At present, due to its characteristics, double grey cardboard packaging has been widely favored by society. However, double grey cardboard manufacturers still need to fundamentally improve the quality, appearance, and applicable value of industrial grey cardboard in order to have market competitiveness and achieve significant development.
