#extrusioncoating Extrusion coating masterbatches are specialized additives used in the extrusion coating process to enhance the performance and functionality of coatings applied to various substrates. Extrusion coating is a manufacturing technique where a molten polymer is coated onto a substrate, such as paper, cardboard, or films, to provide protective, barrier, or decorative properties. Masterbatches are concentrated mixtures of pigments, additives, and resins that are added to the base polymer during the extrusion process. They are designed to improve specific properties of the coating, such as adhesion, slip, anti-block, anti-static, UV resistance, heat resistance, and printing capabilities.
