Dalian, April 2025 ——Dalian Bohai Rubber & Plastic Co., Ltd. announced that its independently developed food-grade sealing ring products have passed both the National Food Safety Standard (GB 4806.11-2023) and Japan's Food Sanitation Law test 370 (JFSL 370). This makes the company one of the few domestic enterprises that simultaneously meet both domestic and international specifications for food-grade rubber products. This certification covers sealing rings made from materials such as Nitrile Butadiene Rubber (NBR) and Silicone Rubber (VMQ), marking the company's products as leaders in food safety, high-temperature resistance, and chemical corrosion resistance.

Technological Breakthrough: Full Process Control from Raw Materials to Production

To meet the stringent requirements for food-grade sealing rings, the company has achieved a quality breakthrough through the following technological upgrades:

1. Environmentally Friendly Material Selection : Utilizing a sulfurization odor-free process and low-leaching formula technology to ensure no chemical contamination risk when the sealing rings come into contact with food.

2. Full-Process Traceability : From raw material procurement to the production stage, the ISO 9001 quality management system is strictly implemented, and supply chain quality is strengthened through regular supplier audits.

3. Performance Optimization : Product testing shows that indicators such as heavy metal migration and VOC residue far exceed standards, making them suitable for scenarios like food processing equipment, packaging machinery, and drinking water systems.

Currently, the company's food-grade sealing rings have entered mass production, and strategic partnerships have been established with several food equipment manufacturers.
