描述
PRIMACOR 3460 EAA Resin is an ethylene acrylic acid copolymer designed for extrusion coating and lamination applications. It is widely used as an adhesive and sealant layer in flexible packaging structures requiring strong bonding between polyethylene and polar substrates such as paper, aluminum foil and paperboard.
SK PRIMACOR 3460 EAA Resin provides excellent heat sealability, outstanding hot tack and strong adhesion to metallic and cellulosic substrates. It is specifically designed for high-speed extrusion coating processes and low-temperature processing conditions, ensuring stable production efficiency and consistent coating quality.
This grade also offers excellent resistance to delamination, good toughness and moisture-insensitive performance, making it suitable for demanding multilayer packaging applications such as foil lamination, paper coating and liquid packaging structures.
With a typical acrylic acid content of ~9.7%, density of 0.938 g/cm³ and melt index of 20 g/10 min, PRIMACOR 3460 is optimized for fast processing and excellent adhesion performance.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original SK PRIMACOR 3460 EAA Resin with stable supply, technical support and global delivery service.
