Anti-fog for PP cold fog applications

Einar® 618 will provide good anti-fog performance in PP film and is primarily suited for cold fog applications but will also have good properties in a hot fog use.

Einar® 618 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%.

Anti-fog for PP hot fog applications

Einar® 422 is a new 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.

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%
