Antigrasa HRN-ECO24: High-Resistance Greaseproof Technical Barrier for Baking Environments
The HRN-ECO24 greaseproof technical barrier is a high-performance functional coating specifically formulated for flexographic printing. Its main function is to act as a sealing shield that prevents the penetration and migration of oils and fats through the substrate. Available in water-based or UV technology, this coating maintains the mechanical and aesthetic integrity of the packaging, preventing weakening, halos, and lipid stains. It is ideal for the food packaging sector (bakery, fast food, snacks) and cosmetics, guaranteeing a premium finish that withstands demanding conditions such as baking, while optimizing overall printability.
Operational Advantages on Press
- High oil and grease repellency: Drastically minimizes transparency, stains, and greasy halos on paper and cardboard substrates.
- Substrate integrity and stiffness: Prevents structural softening caused by prolonged lipid absorption.
- Excellent printability and stability: Creates a uniform surface that reduces mottle and promotes superior ink adhesion.
- High in-line processability: Formulated to maintain high speeds in flexographic units and coaters, offering a stable coefficient of friction (COF) and high mechanical resistance.
- Sustainability profile (water-based version): Features low volatile organic compound (VOC) emissions, easy ink fountain cleaning, and compatibility with mono-material designs to enhance recyclability.
