Base greaseproof paper (beating degree 75°SR) is unwound and passed through an extrusion coater. Molten LDPE (low‑density polyethylene) at 280‑320°C is extruded onto the paper via a slot die, then pressed against a chill roll to solidify. The coating can be applied to one or both sides. The laminated paper is then slit and rewound. No solvent use.
