As an accredited Vat Dyes factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Vat dyes are packed in 25 kg high-density polyethylene drums with secure lids, clearly labeled with product name, batch, and hazard information. |
| Shipping | Vat Dyes are shipped in tightly sealed, moisture-proof containers to prevent contamination and degradation. Packaging typically includes fiber drums, HDPE bags, or cartons, clearly labeled with hazard identification. They are stored and transported in a cool, dry place, complying with relevant chemical safety and regulatory guidelines to ensure safe handling and delivery. |
| Storage | Vat dyes should be stored in a cool, dry, and well-ventilated area, away from sources of moisture, heat, and direct sunlight. Containers must be tightly sealed to prevent contamination and absorption of moisture. Keep them away from incompatible substances, such as acids and oxidizing agents. Proper labeling and adherence to safety guidelines are essential to ensure safe storage and handling. |
