Main Product Benefits

  • Excellent Optical Properties. High transparency and good surface gloss provide a clear, glass-like appearance. Low yellowness ensures clean and attractive finished bottles, suitable for premium beverage packaging.
  • Strong Mechanical Performance. High intrinsic viscosity delivers good tensile strength and impact resistance. Excellent dimensional stability supports thin-wall and lightweight bottle designs with reliable performance.
  • Low Acetaldehyde Content. Very low acetaldehyde (AA) generation, typically ≤ 1.0 ppm, helps protect beverage taste and odor, meeting the requirements for bottled water and soft drinks.
  • Good Processing Stability. Optimized structure ensures smooth melt flow and stable processing. Fast reheating performance supports high-speed bottle production, while low dust improves production efficiency and consistency.

Typical Applications

  • Carbonated soft drink bottles
  • Bottled water and mineral water containers
  • Large-volume water bottles (3-gallon / 5-gallon)
  • Juice, tea, and functional beverage packaging
  • Other food-grade PET containers requiring high clarity and strength

Processing Characteristics

  • Recommended for Injection Stretch Blow Molding (ISBM).
  • Rapid heat absorption enables lower energy consumption and higher productivity.
  • Stable melt behavior reduces degradation and ensures uniform bottle wall thickness.
  • Suitable for both standard and high-speed production lines.
