As an accredited Tea Polyphenols factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Tea Polyphenols are packaged in a 25kg woven fiber drum with an inner plastic liner, ensuring moisture protection and product integrity. |
| Storage | Tea polyphenols should be stored in a tightly sealed container, protected from light, moisture, and heat to prevent oxidation and degradation. Ideally, they should be kept in a cool, dry place, such as a refrigerator or a temperature-controlled environment below 25°C. Avoid exposure to air and strong odors, as tea polyphenols are sensitive to environmental factors. |
| Shipping | Tea Polyphenols are securely packaged in sealed, food-grade containers or drums to prevent contamination and moisture ingress. Each shipment is labeled according to regulatory requirements and shipped via reliable carriers. Temperature and humidity controls are maintained when necessary to ensure product quality and preserve its antioxidant properties during transit. |
