Description
SK PRIMACOR 3150 is an EAA resin, also known as Ethylene Acrylic Acid Copolymer. It is designed to provide good flexibility, heat-sealing performance and adhesion to polar substrates. This material can be used in extrusion coating, paper-plastic lamination, aluminum foil lamination, multilayer co-extrusion tie layers, hot melt adhesive modification and flexible packaging applications.
PRIMACOR 3150 has a relatively low acrylic acid content and good processing stability. It is suitable for composite structures that require flexibility, heat sealability and stable extrusion performance. Compared with standard PE materials, EAA can improve adhesion to polar substrates such as paper, aluminum foil, metals, EVOH, PA and PET.
