Abstract:In this work, different food‐contact experimental and commercial aqueous polymeric dispersions were applied to paperboard via rod coating technology to achieve <5% non‐cellulosic content. Barrier (water, moisture and grease), mechanical (tensile and bending) and converting (heat‐sealing and creasing) properties were analysed before tray formation trials on pilot‐scale equipment. Dispersion‐coated samples were compared against polyethylene terephthalate (PET) extrusion‐coated paperboard, the principal indust… Show more
