Performance Advantages of PET CR-8816L Chips

  • Excellent Transparency & Appearance. China Resources PET CR-8816L delivers exceptional optical performance characterized by high brightness and low haze, ensuring crystal-clear visual quality. Its superior clarity enhances premium packaging presentation and strengthens shelf appeal. The low yellowness index enables the production of clean, colorless bottles, meeting the aesthetic standards required for high-end beverage and food packaging applications.
  • Outstanding Processability. Engineered with optimized intrinsic viscosity, PET CR-8816L ensures stable and consistent processing performance. The wide processing window allows smooth operation across various injection molding and stretch blow molding systems, supporting high-speed production environments. Its balanced molecular structure promotes smooth melt flow and excellent preform formation, helping manufacturers achieve uniform wall thickness and superior bottle quality.
  • Low Acetaldehyde Content. The resin features carefully controlled acetaldehyde (AA) levels, making it highly suitable for drinking water and food-contact packaging applications. Low AA generation helps preserve taste and odor neutrality, which is particularly critical for bottled water and sensitive beverage products where flavor integrity must be maintained.
  • Strong Mechanical Performance. PET CR-8816L resin offers high tensile strength and rigidity, ensuring reliable container durability during filling, transportation, and storage. Its good impact resistance enhances product safety, while the robust structural integrity supports lightweight bottle design, enabling material reduction without compromising performance.
  • Controlled Purity & Moisture. Strict quality control ensures low moisture content and minimal impurities, reducing the risk of hydrolytic degradation during processing. Clean resin characteristics contribute to improved production efficiency, stable processing conditions, and a lower defect rate, ultimately maximizing manufacturing yield and finished-product consistency.
