Appearance: Regular, full shape for easy handling and consistent presentation. Elasticity and sealing: Good elasticity helps when sealing bags, reducing the chance of water leakage after sealing. Absorption and storage performance: Porosity is evenly distributed; water absorption is extremely strong; large water storage capacity; volatility (evaporation) of the water agent remains stable. Solubility and texture: Not soluble in water; nonsticky; maintains a consistent evaporation rate of the water agent. Material and compatibility: Made of sponge material with uniform porosity; designed to interact with waterbased liquids without dissolving or sticking. Practical advantages: Provides reliable moisture control, stable evaporation behavior, and leakresistant bag sealing in a compact sponge form. Use scenarios: Packaging and storage: Seal moisturesensitive products (such as seeds, spices, or dry goods) in bags to minimize leaks and maintain stable humidity levels. Laboratory or industrial processes: Use in setups involving waterbased solutions to help regulate evaporation rates without dissolving or sticking to containers. Home or consumer care: Use with moisturesensitive cosmetics or household items that require consistent humidity control during storage or transport.
