PET CR-8863 polyethylene terephthalate resin is specially designed for hot-fill bottle applications, such as tea beverages, fruit juice, flavored drinks, and similar products requiring elevated filling temperatures (typically 80–95 °C). This grade features low acetaldehyde and low heavy metal content, excellent color values, stable intrinsic viscosity, high transparency, and improved heat resistance — ideal for high-speed, food-grade packaging production.

Features & Processing Performance

  • Hot-fill compatible: Engineered for bottle production where filling temperatures range between 80 °C and 95 °C (e.g., teas, juices).
  • Low acetaldehyde & heavy metal content: Supports flavor retention and meets food-contact standards.
  • High clarity and brightness: High L* and low b* values ensure a clean, clear, and visually appealing final product.
  • Stable intrinsic viscosity: Improves blow-molding performance and maintains excellent bottle quality.
  • Good heat stability and dimensional control: Bottle maintains structural integrity during hot-fill and cooling cycles.

Major Applications of PET CR-8863

  • Hot-fill beverage bottles (tea, juice, sports drinks)
  • Condiment and flavored drink containers
  • Large-capacity drinking bottles requiring thermal resistance
  • General food and beverage packaging with stringent clarity requirements

Recommendations for Use

  • Material Selection: Choose CR-8839 if producing transparent hot-fill PET bottles that require durability, clarity, and high-quality appearance.
  • Supplier Verification: Request the latest TDS from the supplier, focusing on IV, AA content, color values, moisture, and powder content.

Processing Suggestions:

  • Ensure material is properly dried (≤50 ppm moisture)
  • Optimize injection and blow-molding temperatures based on bottle size and filling temperature
  • Conduct pilot testing for heat resistance, clarity, and mechanical performance

Storage: Keep in cool, dry conditions; avoid moisture absorption or sunlight exposure; maintain warehouse controls to support long-term quality
