Einar® 422

Einar® 422 by Palsgaard is a high-performance, food-grade, internal anti-fogging agent for cast and BOPP film. It is a blend of glycerol & propylene glycol esters made from fatty acids of vegetable origin and is produced in CO₂ neutral factories. It is suitable for masterbatches based on polypropylene (PP).

• Einar® 422 key features and benefits include:
• It provides hot fog performance in PP food packaging.
• It exhibits highly effective replacement for conventional anti-fog chemistries such as glycerol monooleate or sorbitan esters.
• It shows no adverse effects on mechanical, optical and barrier properties.
• It helps to avoid fogging from hot packaged food.
• It keeps food wrap films and other types of packaging transparent.
• It ensures a clear view of the packaged product by reducing the surface tension, which causes condensed droplets on the polymer surface to spread into a thin and transparent film.
• It provides high heat resistance and low volatility.
• Recommended loading level of the grade is 0.5-1.0% for random copolymer PP layer and 1.0-1.5% for homopolymer PP film.
• It has a shelf life of minimum 24 months.
