Among the available options, water-based aqueous coatings come closest to being truly plastic-free. These coatings are made from bio-based resins and create a thin, effective protective layer. While they are often classified as containing plastic, the actual content is typically limited to 0.5%-1%, which is much lower than traditional coatings or laminates. These coatings are water-based, making them an eco-friendly alternative, but the polymer additives used to create the film may still be detected as “plastic” by strict testing methods , Water-based barrier coatings.

The base paper’s weight directly affects stiffness, opacity, and printability. A ±3% tolerance ensures uniform density across rolls and lots, which translates to predictable coating behavior and end-use performance.
