As an accredited Calcined Kaolin factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Calcined Kaolin is typically packed in 25 kg multi-layer kraft paper bags with inner plastic lining for moisture protection, labeled accordingly. |
| Container Loading (20′ FCL) | 20′ FCL for Calcined Kaolin typically loads 22-24 metric tons, packed in 25kg or 1-ton jumbo bags, safely palletized. |
| Shipping | Calcined Kaolin is typically shipped in multi-layer paper bags, bulk bags, or lined containers to prevent moisture absorption and contamination. It should be stored and transported in a dry, well-ventilated area. Proper labeling and handling procedures are essential to ensure safety and maintain product quality during shipping. |
| Storage | Calcined Kaolin should be stored in a cool, dry, and well-ventilated area, away from moisture and incompatible substances. Keep it in tightly sealed containers or original packaging to prevent contamination and minimize dust generation. Ensure the storage area is clearly labeled, clean, and protected from physical damage. Avoid exposure to strong acids, strong bases, and humidity to maintain product quality. |
| Shelf Life | Calcined Kaolin typically has an indefinite shelf life if stored in a dry, cool, and well-sealed container to prevent moisture absorption. |
