JADE CZ‑328 is a high-performance bottle-grade polyethylene terephthalate (PET) resin produced by JADE. This grade is specifically designed for carbonated beverage bottles and large-capacity bottles (e.g., 3-gallon and 5-gallon containers).

CZ‑328 JADE PET offers high intrinsic viscosity, excellent mechanical strength, superior barrier properties, low acetaldehyde content, and wide processing adaptability, making it ideal for high-speed blow molding, injection molding, and thick-walled bottle production.

Features and Advantages of JADE CZ‑328

  • High Strength and Viscosity. Higher IV compared to standard water bottle resins, suitable for thick-walled or large-capacity bottles, ensuring structural integrity and pressure resistance.
  • Superior Barrier Performance. Effectively prevents carbonation loss or bottle cracking, maintaining beverage quality and shelf life.
  • Excellent Transparency and Color Control. High L value and low b value produce clear, bright bottles with excellent visual appeal.
  • Wide Processing Adaptability. PET JADE CZ‑328 is suitable for high-speed blow molding, injection molding, and thick-walled bottle production with good wall-thickness uniformity.
  • Food-Grade Safety. Low acetaldehyde and low impurity levels meet beverage, food, and pharmaceutical packaging hygiene requirements.

Main Applications

  • Carbonated Beverage Bottles: High-pressure, thick-walled designs
  • Large-Capacity Bottles: 3-gallon and 5-gallon beverage containers
  • Food and Pharmaceutical Packaging: Oil bottles, pharmaceutical bottles, cosmetic bottles
  • PET Sheets and Films: Thermoforming, trays, and other high-strength, clear packaging materials

Packaging and Storage

  • Packaging: Usually 25 kg bags or 1,100 kg jumbo bags with polyethylene liners.
  • Storage: Cool, dry, ventilated warehouse; avoid sunlight, moisture, and contamination.
  • Shelf Life: Recommended usage within 12 months from production date to ensure optimal performance.
  • Transportation: Non-hazardous; handle to prevent damage, moisture ingress, and contamination.
