Main Applications of PET JADE CZ‑302

  • Beverage Bottles: Purified water, mineral water, soft drinks
  • Candy and Flavor Containers: Candy bottles, flavoring bottles
  • Cosmetic and Household Packaging: Shampoo, detergent, and cosmetic bottles
  • PET Sheets and Films: Sheet, film, and other packaging applications requiring clarity and hygiene

Packaging and Storage

  • Packaging: Typically 25 kg bags or bulk jumbo bags (~1,100 kg) with polyethylene liners.
  • Storage: Store in a cool, dry, ventilated area; avoid sunlight, moisture, and contamination.
  • Shelf Life: Recommended usage within 12 months for optimal processing performance.
  • Transportation: Non-hazardous; handle to prevent moisture ingress or contamination.

Processing Recommendations

  • Drying: Pre-dry at 160–180 °C for 4–6 hours, dew point below −40 °C to prevent hydrolytic degradation.
  • Processing Temperature: Melt temperature 275–293 °C.
  • Molding Considerations: Adjust mold and blow temperatures, residence times, and cooling rates based on equipment and bottle design.
  • Precautions: Avoid prolonged high-temperature residence, ensure stable feed, and prevent moisture exposure.
