1. Core Competitive Advantages
- Largest Bottle Flakes Producer in China: The Yisheng group (including Hainan Yisheng and Yisheng Dahu) has a total bottle flakes capacity of 4.7 million tons/year, accounting for nearly 40% of the national total, making it a leading enterprise in the global polyester bottle flakes industry.
- Integrated Industrial Chain Layout: The controlling shareholder, Rongsheng Petrochemical, owns a complete industrial chain from PX—PTA—polyester, enabling self-sufficiency in raw materials, significantly reducing production costs, and ensuring product quality stability.
- Advanced Technology and Cost Leadership: Utilizing the mainstream domestic PTA two-step polymerization process (CP+SSP), the processing fee is only 350 RMB/ton, offering a significant cost advantage.
- Green and Intelligent Manufacturing: Hainan Yisheng has been listed among Hainan’s Top 50 Private Enterprises, with R&D investment ranking high. It leverages the free trade port policy to expand overseas markets and, in 2024, successfully exported via the Yangpu-Middle East shipping route, receiving tax rebates exceeding 100 million RMB.
- High-Quality Customer Base: Products are certified by FDA and EU for food contact materials, establishing long-term strategic partnerships with leading domestic and international beverage and food companies, enjoying high market recognition.
2. Food-Grade PET Bottle Flakes Product Series
Yisheng’s bottle-grade polyester chips (PET) are food-grade polymer materials compliant with Chinese GB/T 17931-2018 and international FDA and EU food safety standards. They feature high transparency, low acetaldehyde, chemical resistance, and recyclability, and are widely used in various food and beverage packaging applications.
1. Water Bottle-Grade PET Chips (YS-W01)
- Main Applications: Mineral water bottles, purified water bottles, distilled water bottles, bottled water containers
- Key Advantages:
- Intrinsic viscosity: 0.800 dL/g, narrow molecular weight distribution, excellent processing performance
- Low acetaldehyde content, effectively preventing "plastic taste", ensuring pure beverage flavor
- Good color value, stable viscosity, high transparency, high yield rate
- Suitable for cold-fill packaging, meeting high-speed blow molding line requirements
2. Oil Bottle-Grade PET Chips (YS-Y01)
- Main Applications: Edible oil bottles, liquor bottles, soy sauce bottles, vinegar bottles, and other condiment packaging
- Key Advantages:
- Excellent oil resistance and strong barrier properties, preventing oil penetration
- High thermal stability, suitable for hot-fill processes
- Low acetaldehyde release (<1.0 ppm), compliant with food contact safety standards
- Wide processing window, high molding yield, suitable for blow molding processes
3. Hot-Fill Bottle-Grade PET Chips (YS-H01)
- Main Applications: Packaging bottles for tea drinks, fruit juices, functional beverages, and other products requiring high-temperature sterilization
- Key Advantages:
- Intrinsic viscosity: 0.790 dL/g, stable crystallinity, low thermal shrinkage
- Strong heat resistance, capable of withstanding hot-fill processes above 70°C
- Uniform wall thickness, full stress release, excellent anti-deformation capability
4. Carbonated Beverage Bottle-Grade PET Chips (YS-C01)
- Main Applications: Carbonated drink bottles, sports drink bottles, carbonated water bottles
- Key Advantages:
- High strength and pressure resistance, meeting high-pressure gas storage requirements
- Excellent gas barrier performance, extending product shelf life
- Stable processing performance, suitable for high-speed blow molding production lines
3. Quality & Certification Assurance
Yisheng Petrochemical adheres to a development philosophy of “quality first, safety and environmental protection,” ensuring full traceability throughout production with a robust management system. Its subsidiaries have passed international certifications such as ISO9001, and products meet FDA and EU food contact material standards, guaranteeing safe and controllable quality from raw materials to finished products.
Additionally, the company actively responds to the national “dual carbon” strategy, investing in recycled PET (rPET) technology research and development, promoting the application of food-grade recycled materials, and supporting the industry’s transition toward a “bottle-to-bottle” closed-loop recycling model, fulfilling its commitment to sustainable development.
