Zhejiang Gretrak New Material Technology Co.,Ltd./Xinjiang Blue Ridge Tunhe Degradable Material Co., Ltd., a wholly-owned subsidiary of Xinjiang Blue Ridge Tunhe Technology Co., Ltd., operates dual bases in Zhejiang and Xinjiang. It is a specialized enterprise integrating R&D, production, sales, design, and service of biodegradable materials and other high-tech materials.

The company focuses on independent innovation. In researching degradation cycles of biodegradable/non-biodegradable materials and supplying modified materials, it primarily modifies PBAT and PBS as raw materials. Compared with other polyester materials, its products demonstrate superior toughness, impact resistance, barrier properties, blow molding performance, and easier processing. In 2015, the company entered biodegradable material modification research, rapidly applying products to environmental packaging (e.g., supermarket shopping bags, garbage bags, express delivery bags), agricultural mulch films, and food service sectors. It has promoted biodegradable mulch films covering over 300,000 mu (20,000 hectares) in agricultural fields. In 2022, it developed engineering plastic products like PBT and TPEE, applied in electronics, electrical appliances, automotive, and home appliance industries. By 2023, the company has established an annual modified material production capacity of 20,000 tons. Its degradation-modified products comply with U.S. and European food contact safety standards, having obtained international certifications including EU, Australia, TüV Rheinland biodegradation certifications, EN13432, and ASTM D6400 biodegradability certifications. Products are exported to Europe, Southeast Asia, and other regions, earning recognition from domestic and international clients.

The company possesses complete independent intellectual property rights for raw material formulations, specialized feeding systems, advanced extrusion blow film equipment, and a strong R&D technical team capable of customized solutions. It has signed industry-university-research collaboration agreements with institutions including Sichuan University, South China University of Technology, Zhejiang University of Technology, and Beijing University of Chemical Technology, committed to developing and promoting new technologies, materials, equipment, and products in the biodegradable new materials industry. Leveraging Xinjiang's petrochemical downstream industry alliance platform, the company aims to bridge semi-finished products to end products. Rooted in its East China base, it will seize market opportunities, enhance innovation capabilities, build core competitiveness, and strive to become a domestic top-tier and internationally renowned modified new materials leader. The company has been awarded titles including National High-Tech Enterprise, Zhejiang Province/Xinjiang Uygur Autonomous Region Specialized/Sophisticated/Distinctive/Innovative SME, and China's Top 10 Degradable Plastic Enterprises.
