Long-term pressure resistance is a key functional performance for packaging carton board, stacking paper and industrial backing paper. In the process of warehouse stacking, container transportation and long-term compression storage, ordinary paper is prone to permanent compression deformation, structural collapse and thickness thinning under continuous static pressure. Poor pressure resistance leads to carton flattening, commodity extrusion damage and unqualified stacking specifications, bringing huge economic losses to packaging and logistics enterprises. Most existing strengthening schemes only improve instantaneous burst strength and tensile strength, but cannot enhance the long-term compression resistance of paper. Under long-term continuous pressure, the internal fiber structure will gradually relax and collapse, resulting in irreversible deformation. Blindly increasing paper gram weight to improve pressure resistance will greatly increase raw material costs and reduce product profit margins. Shandong Ludao Energy Technology Co., Ltd. launches professional paper long-term pressure resistance upgrading solutions. By building a stable three-dimensional fiber support structure and enhancing inter-fiber anti-relaxation performance, we effectively resist long-term static compression, avoid structural collapse and permanent deformation. The treated paper maintains stable thickness, stiffness and structural integrity under long-term stacking pressure, improves warehouse stacking safety and logistics compression resistance, reduces packaging damage rate, and helps enterprises achieve high-strength and low-cost packaging paper production.
