An anti fog masterbatch is a type of additive masterbatch specifically designed to prevent the formation of fog or condensation on plastic surfaces, such as polyethylene (PE) or polypropylene (PP) films. It contains active ingredients (usually hydrophilic additives) that migrate to the surface of the plastic, reducing surface tension and allowing water droplets to spread evenly as a thin transparent layer rather than forming visible droplets that cause fogging.
Key Features:
- Prevents fogging: Ensures clear visibility on plastic films, packaging, or greenhouse covers.
- Compatible with common plastics: Works well with PE, PP, PET, and other thermoplastics.
- Easy processing: Added during extrusion or blown film processes without significant changes to mechanical properties.
- Food-safe options: Some anti-fog masterbatches comply with FDA or EU regulations for food contact.
Common Applications:
- Food packaging films – keep packaged foods visible and appealing.
- Greenhouse films – improve light transmission and plant growth.
- Plastic covers – maintain visibility on industrial or household products.
- Beverage packaging – prevent condensation on cold drinks.
In short, anti-fog masterbatch is a functional additive that enhances the clarity and usability of plastic products in humid or condensation-prone environments.
