How do you coat paper with pe?

To coat paper with polyethylene (PE), you typically use a process called extrusion coating. In this method, molten polyethylene is extruded onto a moving web of paper, which allows the PE to bond with the paper surface as it cools and solidifies. Alternatively, you can use a lamination technique, where a thin layer of PE film is adhered to the paper using heat and pressure. This coating provides moisture resistance and enhances the durability of the paper.
