描述
PRIMACOR 3340 EAA Resin is an ethylene acrylic acid copolymer specifically designed for extrusion coating, coextrusion coating and lamination applications. It is commonly used as an adhesive or sealant layer in flexible packaging structures where strong bonding to paper, paperboard, metals and polyethylene is required.
SK PRIMACOR 3340 EAA Resin provides excellent adhesion performance, strong hot tack and reliable heat sealability. Its acrylic acid functionality improves polarity and helps the resin bond to polar substrates that conventional polyethylene cannot easily adhere to, making it suitable for multilayer packaging and liquid packaging board laminates.
This grade also offers good oil and grease resistance, moisture-insensitive performance and stable processing behavior during extrusion coating. With a melt index of 9.0 g/10 min, density of 0.932 g/cm³ and acrylic acid comonomer content of 6.5%, PRIMACOR 3340 provides a balanced combination of adhesion, coating stability and sealing performance.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original SK PRIMACOR 3340 EAA Resin with stable sourcing, technical support and global delivery service.

Advantages
PRIMACOR 3340 EAA Resin is a practical adhesive and sealant resin for converters that need reliable bonding between polyethylene and polar substrates. It helps improve interlayer adhesion in multilayer structures, reducing delamination risk during packaging conversion and end-use performance.
Compared with standard polyethylene, EAA resins provide stronger bonding to metallic, paper and cellulosic substrates. This makes PRIMACOR 3340 especially useful in extrusion coating and liquid packaging board structures where adhesion and seal reliability are both important.
