Introducing plant-based and food-grade anti-fogs for PP and PE

How does anti-fogging on packaging help prevent food waste? Studies show that many consumers prefer foods in crystal-clear, dry packaging rather than ones containing moisture.

Hot or chilled food? PP or PE film? Our Einar® products are designed to help you overcome fogging, and keep food out of the bin.

Anti-fog for PP cold fog applications

Einar® 618 is an internal anti-fog additive tailor-made for primarily cold fog applications in packaging and films based on polypropylene but will also give good performance in hot fog conditions. This advanced polyglycerol with a selected fatty acid profile works well in both cast and BOPP film and will be a fast-acting anti-fog, producing clear and transparent film for an extended period of time.

The recommended loading level of Einar® 618 is 1.0 - 1.5% when incorporated in a random copolymer PP layer and loading levels for homopolymer PP film are 1.5 - 2.0%. Einar® 618 is available in liquid form and has worldwide approval for food-contact applications.

Anti-fog for PP hot fog applications

Einar® 422 is a new internal hot-fog development and will be an excellent choice for any PP anti-fog application for packing of hot foods on display or microwaved ready meals. Performance is immediate and consistent throughout the period of storage at elevated temperatures.

Specifically developed for the demanding hot-fog conditions in polypropylene, Einar® 422 ensures a clear view of the packaged product by lowering the surface tension which causes the condensed droplets on the polymer surface to spread into a thin transparent film.

Einar® 422 provides instant as well as prolonged anti-fog effects in various PP types.

The recommended loading level of Einar® 422 is 0.5 - 1.0% when incorporated in a random copolymer PP layer and loading levels for homopolymer PP film are 1.0 - 1.5%. Einar® 422 is available in pellet form and has worldwide approval for food-contact applications.
