Anti-fog masterbatch: Keeps packaging and films clear and transparent!
In fields such as food packaging, agricultural films, and cold chain transportation, the fogging on the surface of plastic products due to temperature differences is a common problem. The fogging not only affects the display of product appearance but also may shorten the preservation period and reduce light transmittance. Anti-fog masterbatch is specially designed to address this issue. By adding special surface active agents to polyolefin materials, condensed water is evenly spread out as a continuous water film, thereby restoring the original transparency of the material.
Quick anti-fog effect, lasting for a long time
The active ingredients in the Anti-fog masterbatch are uniformly dispersed into the resin matrix during the melting processing. After the product is formed, these molecules gradually migrate to the surface, reducing the interfacial tension of water. When the environmental humidity increases, the condensed water vapor no longer forms discrete droplets but quickly spreads into a transparent thin layer. Depending on the addition ratio and usage scenario, the anti-fog effect can last for several weeks to several months, meeting the usage requirements in alternating cold and hot environments and high humidity conditions.
Compatible with various resins and processes
This masterbatch is based on polypropylene or polyethylene and has good compatibility with materials such as PP, PE, and EVA. It can be widely used in processes such as blow molding films, cast films, injection molding parts, and sheet extrusion. During the processing, it does not precipitate, does not stick to the rollers, has little impact on the mechanical properties of the products, and does not produce odors or affect the printing adhesion.
Multifunctional collaboration, meeting specific needs
In addition to the general Anti-fog masterbatch, we can also provide anti-fog and anti-static composite, anti-fog and smooth composite and other series of products. For agricultural greenhouse films, the long-lasting anti-fog masterbatch can reduce the damage to crops caused by dripping water and improve the utilization rate of indoor sunlight; for frozen food packaging, the low-temperature anti-fog masterbatch remains active in sub-zero environments, avoiding fog formation inside the packaging bag that would affect barcode scanning recognition.
Easy to use, stable quality
The anti-fog masterbatch is supplied in granular form. Simply mix it with the resin raw materials in the preset ratio and it can be put into production. Each batch of products undergoes anti-fog performance testing and dispersion testing to ensure consistency among batches. Users can adjust flexibly according to the thickness of the film, the usage environment and the expected duration of effectiveness.
Choosing Anti-fog masterbatch means choosing to ensure that transparent products maintain clear vision even in humid environments. It does not alter the original structure of the material, but plays a crucial role on the surface, allowing each layer of film to present its intended appearance.
