Recyclable Packaging
A sustainable packaging substrate with a protective layer that dissolves during standard paper recycling replaces traditional plastic-laminated boards. Using repulpable barrier board allows the wood fibers to be fully recovered during the hydrapulping stage. This design prevents the landfill waste associated with mixed-material packaging.
Barrier Chemistry
Water-based polymer dispersions are applied to the board surface to create a thin, flexible barrier against grease, moisture, and water vapor. These specialized coatings are formulated to lose their integrity when exposed to the high temperature and alkaline conditions of the recycling mill. This chemical behavior ensures that the barrier material does not clog the pulp screens or contaminate the recycled paper stream.
Functional Performance
Replacing polyethylene coatings with these eco-friendly alternatives allows brand owners to meet strict environmental targets without sacrificing performance. Under normal storage conditions, repulpable barrier board provides the same protection as plastic laminates, keeping food fresh and preventing grease stains on the outer package. The board can be printed, folded, and glued on standard packaging machinery, requiring no special adjustments or new equipment.
This compatibility ensures a smooth transition to sustainable packaging materials for food service and retail brands, while also appealing to environmentally conscious consumers.
