Residual peculiar odor is a common quality problem that restricts the grade upgrade of food-grade paper, household paper and high-end printing paper. In pulping, bleaching, sizing and auxiliary agent adding processes, chemical residues, organic decomposition products and microbial metabolites will cause faint peculiar odor on finished paper. Unqualified odor will directly cause food packaging paper to fail hygiene testing, household paper to have poor user experience, and gift packaging paper to lose high-end texture. Especially in closed packaging and long-term sealed storage, residual odor will accumulate continuously, resulting in customer complaints and product returns. Traditional deodorization methods rely on fragrance covering, which only masks the odor temporarily, cannot remove odor sources fundamentally, and will cause secondary chemical residue, failing to meet food safety and environmental protection standards. Shandong Ludao Energy Technology Co., Ltd. provides thorough paper deodorization and purification solutions. By decomposing organic odor sources, neutralizing residual chemical substances and inhibiting microbial odor generation, we fundamentally eliminate paper residual peculiar odor without adding fragrant additives. The solution is non-toxic and environmentally friendly, does not affect paper physical performance and printing effect, meets food-grade hygiene requirements, greatly improves paper product comfort and safety, and enhances high-end market competitiveness.
