Silica crystals are a desiccant. This simply means they can absorb and hold water. Our silica crystals are food safe and self indicating. This means that the orange crystals turn white when they have absorbed water. They can be dried in the oven and used again. Great for maintaining the quality of finished goods. Orange silica gel pouches are designed to provide high-performance moisture absorption, ideal for a variety of industries where humidity control is crucial. These pouches are filled with silica gel beads infused with an indicating agent that changes color, providing real-time feedback on moisture saturation levels. When dry, the beads are orange; as they absorb moisture, they shift from light orange to green, signaling when they are full and need reactivation or replacement. For optimal moisture control in shipping containers, storage areas, and packaging, premium orange silica gel pouches ensure that your products stay protected from mold, rust, and damage.
