WiseSheet polymer desiccant sheet is a customizable product with excellent functionality designed by WiseNano. This new type of desiccant product focuses on the compactness and aesthetic needs of product packaging while achieving the drying function. It can solve product instability problems caused by the internal environment of the packaging.
WiseSheet polymer desiccant sheet contains dry particles. The desiccant particles absorb, dehumidify, and reduce the oxidizing reaction inside the packaging. Small volume and excellent moisture absorption are WiseSheet’s characteristics. This technology facilitates controlling the moisture content inside the package at a relatively low level for an extended period. This ensures product quality and stability and offers extended product shelf life. The sheet-like appearance design is more suitable for the shape requirements of flexible packaging, reduces its presence as a desiccant, and satisfies the tactile impression and visual effects of product packaging.
The flexible characteristics of WiseSheet make it more abundant in application scenarios. It is suitable for various  packaging fields such as pharmaceutical, healthcare, diagnostics, and food. The light, thin, and flat shape can be applied to cold-formed blisters, strip packs, diagnostic reagent packaging bags, and all other packages of various sizes and shapes.
