描述
PRIMACOR 3150 EAA Resin is an ethylene acrylic acid copolymer designed for extrusion coating and lamination applications. It is widely used as an adhesive tie-layer material in flexible packaging structures requiring strong bonding between polyethylene, paper and aluminum foil.
SK PRIMACOR 3150 EAA Resin exhibits excellent adhesion to polar substrates including aluminum foil, paperboard, metallized films and polyethylene. It provides good heat sealability, strong drawdown performance and stable processing behavior in extrusion coating systems.
The acrylic acid functional groups in EAA improve polarity and enable strong interfacial bonding, making this grade suitable for multilayer packaging structures and industrial lamination systems.
Compared with conventional polyolefin materials, EAA offers significantly better adhesion and sealing performance, especially in foil-based and paper-based packaging structures.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original SK PRIMACOR 3150 EAA Resin with stable supply, technical support and global delivery service.
