描述
PRIMACOR 3003 EAA Resin is an ethylene acrylic acid copolymer designed for extrusion coating and extrusion lamination applications. It is commonly used as an adhesive or sealant layer in flexible packaging laminates and liquid packaging board laminates.
SK PRIMACOR 3003 EAA Resin provides excellent draw-down and edge stability during extrusion coating. It also offers strong adhesion to paper, paperboard, metals and polyethylene, making it suitable for multilayer structures where reliable bonding and seal performance are required. The grade has a melt index of 7.8 g/10 min and density of 0.935 g/cm³ according to SK’s technical data sheet.
Compared with standard polyethylene, PRIMACOR 3003 EAA Resin offers better polarity and stronger interlayer adhesion. It is especially useful for foil lamination, paperboard coating, liquid packaging and demanding flexible packaging structures that require hot tack, sealability, toughness and moisture-insensitive performance.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original SK PRIMACOR 3003 EAA Resin with quotation support, product document assistance and global delivery service.
