Over the years, paper has evolved far beyond its original form. To meet modern packaging need, many new types of paper have been developed- and PE coated paper is one of the most widely used. You might not recognize the name, but you've definitely encountered it in your daily life.
Structure and process PE coated paper
PE coated paper, also know as laminated paper or poly coated paper, is a composite material made of two layers: a base paper and a PE coating layer.
Process: PE pellets are melted and evenly extruded onto the paper surface through a coating machine. After cooling, pressing and corona treatment, the PE film tightly bonds with the paper surface, forming a smooth and durable composite. The corona treatment increases the surface tension of the PE layer, which improves ink adhesion during printing and ensures stable quality.
