JADE CZ‑333 is a high-performance bottle grade polyester chips specifically designed for hot-filling beverage packaging. It is ideal for beverages that require elevated filling temperatures around 90 °C, such as tea drinks, fruit juices, and other medium-viscosity beverages.

CZ‑333 PET resin offers stable thermal contraction, excellent dimensional stability, low acetaldehyde content, and superior processing performance, making it highly resistant to bottle deformation, beverage discoloration, and oxidation during filling, storage, and transportation.

Product Features & Advantages

  • Hot-Fill Compatibility: Optimized for high-temperature filling (~90 °C) without deformation or loss of bottle integrity.
  • Low Acetaldehyde & High Clarity: Maintains beverage flavor and aroma while ensuring excellent visual appearance.
  • Stable Processing & High Yield: Consistent viscosity and flow properties enable high finished-product rates during blow molding and injection molding.
  • Thermal and Dimensional Stability: Minimizes shrinkage, distortion, or cracking during hot-fill processes.
  • Food-Grade Safety: Low heavy-metal content and compliance with beverage packaging hygiene standards.

Main Applications of PET JADE CZ‑333

  • Hot-fill beverage bottles: tea, fruit juice, and flavored drinks
  • Medium-viscosity beverages requiring stable bottle shape and thermal resistance
  • Blow-molded containers, PET sheets, or films needing clarity and heat resistance

Processing Recommendations

  • Drying: Pre-dry to prevent hydrolytic degradation. Typical conditions: 165–185 °C for 4–6 hours, dew point < −40 °C.
  • Processing Temperature: Barrel temperature for blow or injection molding: 285–298 °C.
  • Mold & Blow Parameters: Optimize thermal contraction, cooling rate, and bottle geometry to maintain shape stability during hot-fill production.
  • Quality Control: Monitor IV, AA, COOH, color values, moisture, and dust to ensure clarity, mechanical strength, and consistent performance.
