PE Coated Paper Cup Bottom Roll is a specialized packaging material made by extruding a thin layer of Polyethylene (PE) plastic onto high-quality base paperboard. It is specifically engineered for the base of disposable paper cups. The PE coating transforms the absorbent paper into a waterproof, heat-sealable material, while the thick paper core provides the structural rigidity needed to support the cup.
