Bottle grade CR-8863 PET chips is known for its excellent clarity, low acetaldehyde content, high intrinsic viscosity, and broad processing adaptability, making it ideal for packaging applications with strict quality and safety requirements.

Performance Advantages of PET CR-8863

  • Excellent Transparency: High brightness (L*) and minimal yellowness (b*) ensure crystal-clear packaging.
  • Low Acetaldehyde Content: Suitable for food and beverage packaging where odour and flavour integrity are crucial.
  • High Intrinsic Viscosity: Offers superior mechanical strength and stability during processing.
  • Optimized for Blow Molding: Suitable for injection stretch blow molding (ISBM) and extrusion blow molding (EBM).
  • Consistent Processability: Wide processing window and stable melt characteristics enable smooth production.

Main Applications

  • Edible oil bottles (1L to 5L)
  • Water, juice, and other beverage containers
  • Cosmetic and pharmaceutical bottles
  • PET sheets and thermoformed packaging
  • Household chemical bottles

Processing Recommendations

  1. Drying temperature: 160–180 °C for 4–6 hours, with final moisture ≤ 50 ppm
  2. Melt temperature: 255–275 °C (depending on equipment and mold design)
  3. Blow molding conditions: Adjust based on wall thickness, mold temperature, and intended application
  4. Post-processing: Allow sufficient cooling to achieve optimal crystallinity and mechanical strength
