Dustproof performance is a core functional index for dust-free workshop paper, precision electronic packaging paper and medical sterile packaging paper. Ordinary paper has loose surface micro-pore structure and static accumulation characteristics, which easily adsorb workshop floating dust, tiny particle impurities and fiber debris. Poor dustproof performance makes paper unable to meet the ultra-clean standards of precision industry packaging, resulting in dust contamination of electronic components, medical equipment and sterile supplies. In high-precision industrial production, tiny paper dust and adsorbed particles will cause equipment precision deviation and product functional failure. Most conventional anti-static and dust removal treatments only eliminate static electricity temporarily or remove surface floating dust, but cannot block the adsorption of ultra-fine particles from the source. The porous structure of ordinary paper still retains strong dust adsorption capacity, resulting in persistent hidden hygiene hazards. Shandong Ludao Energy Technology Co., Ltd. develops professional paper dustproof modification solutions. By compacting surface micro-pore structure and forming an anti-adsorption protective film, we isolate ultra-fine particle adhesion and lock surface cleanliness. The solution is non-toxic and sterile, does not affect paper air permeability and processing performance, maintains long-term dust-free and clean state, and fully meets the ultra-clean application requirements of medical, electronic and precision industrial packaging scenarios.
