Barrier coating transforms paper and linerboard into recyclable alternative to wax and polycoated board

05-01-2018 | Cortec Corporation | Subs & Systems

Cortec Corporation has developed a waterborne moisture barrier coating that gives paper manufacturers the ability to create effective, non-toxic, environmentally-friendly paper and corrugated-board as an alternative to wax and polyethene papers. By using EcoShield Barrier Coating onto their Kraft paper, linerboard, and recycled paper manufacturers can create recyclable and repulpable paper, and boxes that resist oil, moisture, and grease.

The dual moisture and grease resistance of the coating creates a packaging material that improves seal out moisture or other contaminants while protecting against packaging failure or leakage for items that have greasy characteristics.

The application of the coating also enhances a paper’s physical properties such as tear, burst, and tensile strength; elongation, folding endurance, coefficient of friction, and smoothness. The coating can be applied by most common paper roll coaters, including gravure, flex, air-knife, reverse-roll, etc. Drying temperature is 180F-200F (82C-93C). Suggested coating weights are 8-11 pounds per 3000 square foot ream (13-18g/m2).
