Cortec Corporation has pioneered EcoShield Barrier Coating, an environment-friendly alternative to polyethylene and wax paper coatings for the manufacture of moisture resistant paper and corrugated boxes.
EcoShield Barrier Coating is a water-borne barrier coating that is recyclable and 100% repulpable, effectively eliminating the need to use traditional wax and polyethylene coatings.
The coating can be used on kraft and recycled paper, as well as on liners for corrugated boxes, providing a waterproof moisture barrier with excellent oil and grease resistance.
When tested according to ASTM E-96, paper coated with EcoShield Barrier Coating showed very good water vapor barrier properties compared to a polyethylene coated paper and better than commercial waxed paper.
Papers coated with EcoShield Barrier Coating also have better physical properties such as burst, tear, and tensile strength; elongation, folding endurance, coefficient of friction, and smoothness.
EcoShield Barrier Coating is formulated in compliance with FDA Code of Federal Regulations Title 21:
• Components of paper and paperboard in contact with aqueous and fatty foods; and
• Components of paper and paperboard in contact with dry food.
It can be applied by most common paper roll coaters, including gravure, flex, air-knife, reverse-roll, etc. Drying temperature is 180-200 °F (82-93 °C), and suggested paper weights are 8-11 lb/ream (3,000 ft²) (13-18 g/m²).
EcoShield Barrier Coating is a revolutionary coating for the food industry and other sectors that need a recyclable moisture barrier to replace polyethylene coatings.
Thanks to Cortec’s groundbreaking innovation of a repulpable coating that seals contaminants and moisture out of paper/corrugated materials, package manufacturers are now set to transform the industry and make moisture barrier packaging easier on recyclers and the environment.
