WiseFlexDesiccant Film

In the majority of product packaging processes, the presence of a significant amount of moisture within the product packaging is influenced by both the packaging environment humidity and the inherent moisture content of the packaged product itself. Even after the packaging process, the interior of the packaging can accumulate moisture due to external temperature fluctuations. For products sensitive to moisture, such as freeze-dried powders, powdered supplements, granular or compressed pharmaceuticals, diagnostic reagents, and test papers, the occurrence of such moisture can lead to not only visual changes in the product (e.g., clumping, surface crystallization, color alteration) but also alterations in product characteristics resulting from interactions with water molecules present in the moisture.

WiseFlex Desiccant Film - Product
After years of research and development, WiseNano has introduced a novel moisture-absorbing polymer material. These polymer particles can be processed into various flexible films and sheet products to meet the demands of sensitive products requiring active packaging. The desiccant film, created through blown-film processes using these polymer particles, features moisture-absorbing functionality. By reducing water vapor content, it suppresses oxygen reactivity, thus ensuring sustained dry stability and safeguarding the product’s properties.
Characteristics

Uniform and Fine Moisture-Absorbing Pore Distribution

WiseFlex desiccant film possesses the characteristic of an evenly distributed and fine moisture-absorbing pore structure. During the process of moisture migration, water molecules pass through the pores of the desiccant layer and are absorbed by the desiccant particles. The more uniform and fine the pore distribution of the desiccant layer, the easier water molecules can be absorbed by the desiccant particles, leading to quicker and more effective moisture absorption. The even and dense pore distribution of WiseFlex desiccant film enables efficient and rapid moisture absorption.

Selectable and Controllable Moisture Absorption Effect

The moisture absorption rate of the drying layer is influenced by thickness and composition variations. Under identical environmental conditions (25°C, 40% RH):

Thickness Moisture absorption rate
60 μm ≥ 2.0 g/㎡ or ≥ 3.6 g/㎡
80 μm ≥ 6.0 g/㎡
110 μm ≥ 9.0 g/㎡

Application

The primary component of the desiccant film is PE, making it suitable for various film composites (PET, PA, PP, Alu, Fiber, etc.) and enabling the production of diverse composite films, pouches and bags.
