Yisheng Recyle Bottle Grade PET Resin Chips Pellets Granules
Yisheng Petrochemical is a leading domestic producer of polyester bottle flakes, with its subsidiary Hainan Yisheng achieving a breakthrough in food-grade recycled PET (rPET). It is one of the first Chinese companies to obtain FDA food contact approval for rPET production. Leveraging the industrial chain synergy between Rongsheng Petrochemical and Hengyi Petrochemical, the company focuses on the research and production of food-grade rPET flakes, promoting a "bottle-to-bottle" closed-loop recycling model, and serves as a long-term core supplier for renowned brands such as Coca-Cola, Nongfu Spring, and Yibao.
1. Core Competitive Advantages
- National rPET Industry Leader: Hainan Yisheng has established a 50,000 tons/year physical recycling capacity for food-grade rPET, with an additional 90,000 tons/year under construction, making it one of the largest rPET producers in China.
- Global Certification Breakthrough: In 2022, Hainan Yisheng received a No Objection Letter (NOL) from the U.S. FDA, confirming that its rPET can be used under conditions A-H and J to manufacture food-contact containers containing up to 100% recycled content. This marks a significant milestone in overcoming international market access barriers for Chinese rPET.
- Integrated Supply Chain Support: Backed by Rongsheng Petrochemical’s complete PX—PTA—polyester industrial chain, Yisheng ensures raw material self-sufficiency and full quality control, providing a stable foundation for blending virgin and recycled PET.
- Advanced Recycling Technology: Utilizes globally leading Erema physical recycling technology, enhanced with SSP (Solid-State Polycondensation) process, significantly improving purification efficiency and molecular weight stability to meet stringent food-grade safety standards.
- Green and Sustainable Development: Actively responding to China’s “dual carbon” strategy, Yisheng integrates virgin and recycled PET operations, aiming to become a model enterprise for circular economy and drive green transformation across the industry.
2. Food-Grade Recycled PET (rPET) Product Series
Yisheng’s food-grade recycled polyester chips (rPET) are high-performance polymers made from post-consumer PET beverage bottles, processed through physical cleaning, melting, filtration, and SSP enhancement. The product complies with GB/T 40006-2021 recycled plastic standards and international food contact safety requirements such as FDA and EU, offering high transparency, traceability, low carbon footprint, and infinite recyclability.
1. General-Purpose Food-Grade rPET Chips (YS-W100R)
- Main Applications: Mineral water bottles, purified water bottles, non-carbonated drink bottles, food trays, packaging sheets
- Key Advantages:
- Recycled content up to 100%, supporting brand sustainability commitments
- Certified via FDA No Objection Letter, suitable for direct food contact packaging
- Intrinsic viscosity: 0.80–0.84 dL/g, excellent processability, compatible with mainstream blow molding equipment
- Low acetaldehyde content, preserving pure beverage taste
- Fully traceable feedstock sourced exclusively from domestic post-consumer PET bottles, aligning with closed-loop recycling principles
2. High-Strength rPET Chips (YS-C100R)
- Main Applications: Carbonated drink bottles, sports drink bottles, large-capacity packaging containers
- Key Advantages:
- Enhanced with SSP solid-state polycondensation, resulting in narrow molecular weight distribution and high pressure resistance
- Meets high-pressure storage requirements for carbonated beverages, with excellent gas barrier performance
- Can be blended with virgin PET to optimize cost-performance balance
3. Quality & Certification Assurance
Yisheng Petrochemical adheres to a production philosophy of “safety, environmental protection, and traceability.” The rPET manufacturing process is fully digitized, enabling batch-level traceability from waste bottle collection, sorting, and cleaning to regranulation. Products are certified under international management systems such as ISO9001 and ISO14001, ensuring end-to-end safety and control throughout the “bottle-to-bottle” cycle.
Additionally, the company is actively investing in semi-chemical recycling technology research and development, aiming to further enhance rPET quality and expand application scope, solidifying its leadership position in the domestic and global rPET market.
