Sinopec Bottle Grade Virgin PET Resin Chips Pellets Granules
Sinopec Yizheng Chemical Fiber (short for "Yizheng Chemical Fiber") is a key high-end polyester production base and specialty fiber R&D manufacturer under Sinopec, located in Yizheng City, Jiangsu Province. Covering an area of approximately 10 square kilometers, its predecessor was the Yizheng Chemical Fiber Industrial Joint Company, established in 1978, and it officially joined the Sinopec Group in 1998. As one of the leading enterprises in China's polyester industry, the company focuses on green and low-carbon development, striving to become a world-class synthetic fiber and new materials enterprise.
1. Core Competitive Advantages
- Leading Production Capacity: The company has a total polyester production capacity of 3.1 million tons per year, covering polyester chips, staple fibers, hollow fibers, bottle flakes, and more. Its annual capacity for bottle-grade PET chips reaches 500,000 tons, serving as a benchmark project for green industry upgrades.
- Advanced Independent Technology: Utilizes Sinopec’s self-developed short-process medium-viscosity polyester technology, one of the most advanced domestic production technologies for bottle-grade PET. The 500,000-ton-per-year facility, commissioned in early 2025, marks a new breakthrough in China’s non-fiber polyester technology and equipment.
- Model for Green Manufacturing: By optimizing the crystallization system through new processes, carbon emissions are reduced by over 20%, with product premium rate significantly higher than similar facilities, providing a replicable green development model for the industry.
- Industry-Leading Quality: The differentiation rate of polyester products exceeds 99%. The film-grade polyester chips have been awarded the national "Manufacturing Single Champion" title, and the output and sales of polyester staple fiber rank first globally.
- Widely Recognized by Customers: Products are widely used in food, beverages, medical, and packaging fields, and are trusted by many leading industry clients, including well-known brands such as Nongfu Spring and Evian.
