Anti-fog Masterbatch
Prevents fogging on the film surface; maintains clarity and light transmission in food packaging and greenhouse films.
Clear in the cold, bright in the greenhouse.
Anti-fog additives are critical for high clarity and for preserving food freshness, particularly in flexible packaging films used for chilled food products. By preventing fog from forming on the film surface, they improve optical clarity and enhance the shelf appeal of products.
Düderi anti-fog masterbatches prevent fogging, allowing water to spread across the film surface as a uniform, transparent layer. This provides higher light transmission and visual clarity in both agricultural and food packaging applications.
What does fogging cause in a greenhouse?
Agricultural films used in greenhouses and tunnels become saturated with water vapor rising from the soil and plants.
-
Condensation
Water vapor condenses on the cold film surface, forming fog and droplets.
-
Light loss
Fogging reduces the transmission of sunlight through the film.
-
Risk of disease
Water droplets falling onto plants increase the risk of fungal and other diseases.
Application areas
- Food packaging
- Agricultural film
- Mono- and multilayer films
Key advantages
- Keeps food fresh longer
- Enhances visual appeal
- Keeps packaging transparent
- Eliminates fogging
- Provides better sunlight transmission in greenhouses
Homogeneous dispersion through twin-screw extrusion
Intensive mixing with a specific screw design and optimized process parameters ensures homogeneous dispersion of the additive.
-
High concentration
Our anti-fog masterbatches are formulated at high concentrations in polyolefin carrier resins.
-
Effective blending
Thanks to twin-screw extrusion, liquid anti-fog additives are blended efficiently with the molten plastic.
-
Cold fog test
Suitable for monolayer and multilayer films, the product achieves strong results in cold fog tests.
