As an accredited Papain factory, we enforce strict quality protocols—every batch undergoes rigorous testing to ensure consistent efficacy and safety standards.
| Packing | Papain is packaged in a sealed, amber glass bottle containing 100 grams, clearly labeled with hazard warnings and handling instructions. |
| Shipping | Papain is typically shipped in tightly sealed, moisture-resistant containers to preserve its activity and prevent contamination. It should be transported at cool, dry temperatures, away from direct sunlight and incompatible substances. Proper labeling and documentation, including hazard information if applicable, are required to ensure safe and compliant shipping. |
| Storage | Papain should be stored in a tightly closed container in a cool, dry, and well-ventilated area, away from direct sunlight and sources of moisture. Ideally, it should be kept at temperatures between 2–8°C (refrigerated) to maintain its stability and enzyme activity. Protect papain from incompatible substances, such as strong acids, bases, and oxidizing agents, to ensure longevity and safety. |
