How is PE Coated Paper Made?

The most common method for producing PE coated paper is extrusion coating:

1. Base Paper: High-quality paperboard (often called "cupstock" for cups, or other paper types for different applications) is fed into the machine from a large roll.

2. Extrusion: Polyethylene resin pellets are heated until molten in an extruder.

3. Coating Application: The molten PE is then extruded through a flat die, forming a thin, continuous film. This hot film is immediately pressed onto the surface of the moving paperboard.

4. Cooling & Bonding: The coated paper is quickly cooled, often against a chilled steel roller. This rapid cooling ensures the PE firmly adheres to the paper fibers, creating a strong, almost inseparable bond.

5. Winding: The finished PE coated paper is then wound into large rolls, ready for further processing (e.g., slitting, die-cutting, printing).

The thickness of the PE coating can be adjusted, typically ranging from a few grams per square meter (GSM) to 20 GSM or more, depending on the required barrier properties.
