Additives for plastics

Anti-Fogs for Plastics | SABO®FOG

Antifog additives are used to prevent fogging in plastic films, especially in food packaging and agricultural (greenhouse film) applications. Sabo offers a complete range of anti-fogs for use in PE (LDPE, LLDPE), EVA, PP, and PVC. These additives are also used in color masterbatches and plastic compounds as pigment dispersing agents.

“Fogging“ in plastic films refers to condensation of water vapor on the surface in the form of small discrete droplets, which results from differences in surface tension between the water droplet and the polymer surface. Fogging may occur as a result of either a drop in temperature on the inside surface of the film below the dew-point of the enclosed air/water vapor mixture (“cold fogging”), or by cooling of the air near the film to a temperature at which it can no longer retain all the water vapor; excess water condenses upon the film (“hot fogging”).

Fogging of plastic films is associated with a number of problems. In food packaging, fogging reduces the visibility of the product, provides a less attractive appearance of the package, and the presence of droplets can even result in deterioration of product quality. In agricultural films, fogging reduces light transmission, leading to slower growth and lower crop yields. Plants can also be damaged from burning due to lens effects of drops on sunlight. Water dripping from the inside film surface can also be problematic in greenhouse operations.
