Compression resistance is the most critical mechanical performance index for packaging board, carton paper and industrial backing paper. Insufficient compression strength leads to box collapse, paper deformation and stacking damage during warehousing, transportation and palletizing. With the rapid development of modern logistics, high-stack and long-distance transportation puts forward higher requirements for paper compression resistance. Many paper mills improve compression performance by increasing high-grade pulp thickness, which greatly raises production costs and reduces market profit margins. Shandong Ludao Energy Technology Co., Ltd. provides targeted paper compression resistance upgrading solutions. By optimizing fiber interweaving structure and adding high-efficiency pressure-resistant functional auxiliaries, we enhance the vertical compression resistance and structural bearing capacity of paper, effectively improve stacking stability and pressure resistance. The solution does not increase paper basis weight and pulp cost, perfectly solves the pain point of insufficient bearing capacity of low-weight packaging paper, and helps enterprises produce high-strength and low-cost packaging paper to occupy the mid-to-high-end packaging market.
