Packaging and Storage

Packaging

Our sodium silicate powder / dry powder water glass adopts standard industrial packaging with premium kraft paper bags, including 25kg kraft paper bag packaging specifications, and supports customized packaging and labeling according to customer requirements. All kraft paper bag packages are tightly sealed, moisture-proof and dust-proof, which can effectively prevent powder leakage, moisture caking and product contamination during transportation and storage. As a reliable professional sodium silicate powder supplier, we provide flexible packaging solutions and bulk shipping services for global customers who buy sodium silicate powder.

Storage

Our sodium silicate powder / dry powder water glass should be stored in a cool, dry, and well‑ventilated warehouse environment. Keep the product away from direct sunlight, high temperature, and humid conditions to prevent moisture absorption, caking, and deterioration of chemical performance. The kraft paper bag packaging must be kept tightly sealed during storage and handling. Avoid contact with water, moisture, acid substances, and strong oxidizing agents to maintain stable powder fluidity and original modulus properties. Stacking height should be controlled reasonably to prevent package damage and powder leakage. As a professional sodium silicate powder supplier, we recommend standardized dry storage and regular stock inspection to ensure long-term product quality for customers who buy sodium silicate powder in bulk.
