Product Description
Extrusion lamination LDPE resin MFI 7 for waterproof film of liquid packaging box, cement bag covering film
High-performance LDPE extrusion lamination resin (MFI 7 polyethylene) engineered for paperboard lamination resin and flexible packaging. Delivers superior adhesion as an adhesive substrate for foil/OPP films while providing low odor lamination compliance – ideal for food cartons, liquid packaging, and industrial laminates requiring FDA/EC1935 safety and rapid processing speeds.
