Advantages of Sinopec PET BG801

  • Excellent Heat Resistance. PET BG801 is specially engineered for hot-fill bottle applications. Under heat-set blow molding conditions, the resin provides outstanding dimensional stability and heat resistance, helping bottles maintain their shape during filling, transportation, and storage at elevated temperatures.
  • High Transparency and Gloss. The resin delivers excellent optical properties and color consistency. Finished bottles exhibit high transparency, bright appearance, and good surface gloss, enhancing overall packaging presentation and product visibility.
  • Low Acetaldehyde Content. Sinopec BG801 features low acetaldehyde generation, which helps preserve beverage taste and minimize odor impact. This makes the resin particularly suitable for sensitive beverage packaging applications.
  • Stable Processing Performance. The resin offers consistent intrinsic viscosity, stable melt flow behavior, and reliable crystallization control during injection molding and stretch blow molding processes. It supports efficient high-speed production with excellent bottle preform quality.
  • Good Mechanical Strength. Bottles produced with BG801 demonstrate good rigidity, impact resistance, and pressure resistance. The material helps improve packaging durability during transportation, stacking, and handling.

Main Applications

  • Hot-Fill Tea Beverage Bottles. BG801 is widely used in PET bottles for green tea, black tea, herbal tea, and other hot-filled beverage products requiring excellent heat stability.
  • Juice Beverage Packaging. The resin is suitable for juice bottles, fruit beverage containers, and vitamin drink packaging, combining heat resistance with high package clarity.
  • Aseptic Filling Bottles. BG801 can also be applied in aseptic filling systems where stable bottle performance and food-contact safety are required.
  • Food Packaging Containers. In addition to beverage bottles, the resin can be used in transparent food-grade containers, condiment packaging, and various PET packaging applications.
