JADE CZ-328H pet resin bottle grade is produced using purified terephthalic acid (PTA/TPA) and ethylene glycol (EG) as raw materials through an advanced continuous polymerization process. This grade is specifically designed for high-strength beverage packaging applications, especially where excellent blowing performance, clarity, and pressure resistance are required. CZ-328H PET resin offers high intrinsic viscosity, stable molecular structure, and excellent mechanical strength, making it suitable for carbonated beverage bottles and large-capacity containers.

Product Features

  • High Mechanical Strength. Its high intrinsic viscosity and polymer molecular weight ensure excellent tensile strength, impact resistance, and structural integrity of finished bottles—especially important for carbonated beverages under internal pressure.
  • Excellent Barrier Properties. JADE CZ-328H resin delivers superior gas retention capability, reducing CO₂ loss in carbonated drinks and preventing oxygen penetration, resulting in extended shelf life and flavor stability.
  • Outstanding Transparency and Appearance. Low color index and high brightness ensure the final bottles are clear, glossy, and visually appealing. This is particularly important for premium drinking water, cosmetics, and food packaging.
  • Food-Contact Safety. The low acetaldehyde content minimizes odor and taste interference, making the material fully compliant with food and beverage packaging standards.
  • Wide Processing Window. PET CZ-328H supports a variety of processing technologies including injection molding, stretch blow molding (ISBM), film extrusion, sheet extrusion.

Major Application Areas

  • Due to its balanced mechanical, optical, and processing performance, JADE CZ-328H is widely used in:
  • Carbonated soft drink (CSD) bottles
  • Mineral water and pure water bottles
  • Juices, tea, and beverage packaging bottles
  • Large containers (up to 3L–5L and above)
  • Food, edible oil & sauce containers
  • Pharmaceutical & cosmetic packaging bottles
  • Transparent PET sheets and thermoforming applications
  • General molded and injection-molded components
  • Its structural stability and clarity also make it suitable for industrial sheet, film, and electronic part applications when transparency and durability are required.

Storage and Handling Guidelines

  • JADE PET resin must be kept dry and stored in a cool, clean environment.
  • Prior to processing, ensure moisture content is within required limits (≤ 0.2%) to avoid hydrolysis, black spots, haze, or mechanical property reduction.
  • Use within 12 months of production for best performance.
  • Avoid prolonged exposure to high humidity or direct sunlight.
