描述
PRIMACOR 3004 EAA Resin is an ethylene acrylic acid copolymer designed for extrusion coating, coextrusion coating and lamination applications. It is commonly used as an adhesive or sealant layer in flexible packaging and liquid packaging board laminates.
SK PRIMACOR 3004 EAA Resin provides excellent draw-down and edge stability, strong adhesion to paper, paperboard, metals and polyethylene, as well as excellent hot tack and heat sealability. It is suitable for multilayer packaging structures where adhesion strength and seal reliability are critical.
Compared with standard polyethylene, PRIMACOR 3004 EAA Resin offers stronger bonding to polar substrates and better seal-through-contamination performance. This makes it useful for foil lamination, paperboard coating, liquid packaging and demanding flexible packaging structures.
Shenzhen Ruiqing International Trade Co., Ltd. supplies original SK PRIMACOR 3004 EAA Resin with quotation support, product document assistance and global delivery service.

Advantages
PRIMACOR 3004 EAA Resin is designed for converters that require stable extrusion coating performance and strong adhesion to difficult substrates. Its acrylic acid functionality improves polarity, allowing the resin to bond well to paper, aluminum, metallized substrates and polyethylene.
The grade is especially useful where hot tack, sealability and seal-through-contamination performance are important. In liquid packaging or flexible packaging structures, this helps improve package reliability and reduce delamination risk during converting and end use.
