Key Features of Sinopec PET BG80

  • High Clarity and Excellent Appearance. PET BG80 delivers outstanding optical performance. Finished bottles exhibit high transparency and a clean, glossy appearance, making it ideal for premium drinking water packaging.
  • Low Acetaldehyde Content. The resin is produced under controlled polymerization and solid-state polycondensation processes, resulting in low acetaldehyde levels. This helps reduce odor formation and ensures better taste preservation for bottled water.
  • Stable Processing Performance. Sinopec PET BG80 provides consistent melt behavior and balanced crystallization characteristics, making it well-suited for high-speed injection stretch blow molding (ISBM) lines with excellent production efficiency and stable output.
  • Good Mechanical Strength. The material offers a balanced combination of rigidity and impact resistance, ensuring reliable performance during filling, transportation, and storage.
  • Food-Grade Safety Compliance. BG80 complies with food-contact regulations and is suitable for direct beverage packaging applications.
