JADE CZ‑318 is a premium bottle grade polyethylene terephthalate (PET) resin developed by JADE for high-strength, high-performance packaging applications. This grade is designed to offer higher intrinsic viscosity, superior transparency, excellent mechanical performance, low acetaldehyde content, and a wide processing window.

CZ‑318 PET resin is suitable for a wide range of applications including carbonated beverage bottles, small edible oil bottles, liquor bottles, pharmaceutical bottles, cosmetic containers, and PET sheets. Its high viscosity and robust performance make it ideal for thicker-walled or more complex-shaped bottles, while maintaining clarity and hygiene standards.

Performance Features and Advantages of JADE CZ‑318

  • High Strength & Excellent Mechanical Performance: Compared to standard water bottle PET resins, JADE CZ‑318 provides higher viscosity and structural rigidity for more demanding bottle designs.
  • Superior Transparency and Color Control: High L-value and low b-value produce clear, bright, visually appealing bottles.
  • Good Barrier Properties & Wide Processing Window: Suitable for thicker, small-sized, or complex-shaped bottles, as well as PET sheet and film applications.
  • Low Acetaldehyde and Low Impurity Levels: Ensures flavor retention and purity of contents such as edible oils, beverages, and pharmaceuticals.
  • Multi-Process Compatibility: Suitable for injection molding, blow molding, and sheet extrusion.

Main Applications

  • Small Bottles: Edible oil bottles, pharmaceutical bottles, liquor bottles, and cosmetic containers.
  • Carbonated Beverage Bottles: For certain specifications requiring higher strength.
  • PET Sheets & Films: Suitable for thermoformed packaging materials, trays, and other high-transparency applications.

Packaging and Storage

  • Packaging Options: Typically 25 kg bags or 1,100 kg jumbo bags with polyethylene liners.
  • Storage Conditions: Store in a cool, dry, ventilated area; avoid direct sunlight, moisture, and contamination.
  • Recommended Shelf Life: 12 months from the production date to maintain optimal processing properties.
  • Transportation: Non-hazardous; handle to prevent bag damage, moisture exposure, and foreign contamination.
