What is BOPP Anti-Fog Film?
BOPP anti-fog film is a specialized BOPP film with a surface treatment that prevents water droplets from forming on the inside of food packaging. Instead of fogging up, water spreads into a transparent layer.
How Anti-Fog Coating Works
The anti-fog coating reduces the surface tension of the BOPP film. When water vapor contacts the surface, it spreads evenly as a transparent layer instead of forming discrete droplets that scatter light and cause fogging.
