High Performance for Demanding Packaging Requirements

To meet the needs of the board and flexible packaging industries, Omya offers a variety of barrier coatings based on natural or synthetic polymers depending on the performance required. All of our barrier solutions are ready-to-use, water-borne, and supplied at high solids content. This allows the use of existing application equipment such as coating, converting, or printing devices. Omya barrier coatings feature full recyclability or even bio-degradability, food contact compliance, and an attractive price-performance level.
Best Performance for Highest Demands
A portfolio of water-borne barrier coatings based on acrylic co-polymers that are easy to blend with other components for food packaging applications. Featuring exceptionally long product shelf life, Extomine is your preferred choice for high performance at an optimized total applied cost.
Extomine Barrier Coatings
Extomine M protects food against mineral oil (MOSH, MOAH) and other harmful substances. It has a minimal tendency to block and acts as a molecular sieve, shielding food from regulatory problematic substances such as bisphenols and preserving aromas.

EarthGuard, EarthWrap, and 
Extomine G are alternatives to fluorine chemical solutions (PFAS) or polyolefins (PE, PP). They provide superb oil and grease resistance for all kinds of application methods. If additional properties such as water repellence and reduced vapor transmission are required EarthWrap is the right choice. If you need barrier with sealing properties we recomend Extomine G.
