Michem® Flex Barrier
Product Line
High-performance water-based coatings applied superficially on both monolayer films and papers. Compatible with standard application systems (rotogravure, flexo, rod, or roller) with conventional drying, facilitating the transition to sustainable packaging without complex machinery modifications.
- Very high oxygen barrier (+ aroma and mineral oil barriers)
- PET <0.8 cc/m²/day; Met-PET <0.03 cc/m²/day
- BOPP, MDOPE <10 cc/m²/day
- Papel <3 cc/m²/day
- Over-printable
- FDA indirect food contact
- Some products may be used as metallization primer and/or metal layer topcoat
- Some products may be used as extrusion primer and OTR coating combo
- Can be combined with functional heat-seal coating to provide all-in-one solution for paper packaging

What is a Functional Barrier Coating?
Unlike traditional laminations that use multiple layers of hard-to-recycle plastics, our functional coatings are water-based liquid solutions. They are applied as an ultra-thin layer onto substrates like paper or mono-material films. Once dry, they create an invisible yet powerful barrier against oxygen, aromas, and grease, enabling the final package to be recyclable and lightweight without sacrificing product protection.
