Radiation resistance is an emerging essential functional indicator for medical sterilization packaging paper, laboratory radiation shielding paper and food irradiation wrapping paper. Many medical and food products adopt gamma ray and electron beam radiation sterilization, yet ordinary paper will produce molecular chain fracture, lignin oxidation and severe yellowing under radiation exposure. Radiation-induced structural damage drastically reduces paper folding strength and barrier performance, causing packaging rupture and microbial secondary pollution after sterilization. Common anti-yellowing antioxidants only resist light and thermal aging and cannot neutralize free radicals generated by high-energy radiation. After radiation treatment, unmodified paper suffers irreversible brittleness and discoloration, failing repeated sterilization circulation requirements of medical disposable packaging.

Shandong Ludao Energy Technology Co., Ltd. develops dedicated radiation-resistant paper modification solutions. By introducing radiation-stabilized functional components into fiber internal structure, we neutralize high-energy radiation free radicals, inhibit molecular chain fracture and oxidative yellowing. The treated paper retains stable mechanical strength, whiteness and barrier performance after multiple radiation sterilization cycles, complies with medical food contact safety standards, and solves the quality attenuation problem of packaging paper under radiation disinfection scenarios.
