Extrusion coating is a process where a molten polymer is applied to a substrate, such as paper or film, to impart protective or functional qualities. This technique is commonly used in food packaging and industrial applications to enhance sealing and barrier properties, thus extending the product’s shelf life. The process ensures consistent coating thickness and quality through high-speed processing and precise control. Sustainability adaptations include the use of recyclable materials and eco-friendly coatings to minimize environmental impact
