Description
Exxtra Adhere EAA8308 is an ethylene acrylic acid copolymer resin designed for extrusion coating and coextrusion coating applications.
With an acrylic acid content of 7.5 wt% and a melt index of 8.3 g/10 min, EAA8308 provides good adhesion to polar substrates including aluminum foil, metallized films, paper, iron, steel, and glass.
It offers an excellent balance of adhesion to substrates and interlayer adhesion with coextruded LDPE and EVA materials, making it suitable for packaging, coating, and lamination structures.

Processing Guidelines
Recommended extrusion coating temperature: 260–280°C / 500–536°F
- Avoid processing temperatures above 300°C / 572°F, as prolonged exposure may cause resin degradation.
- Use corrosion-resistant metals or suitable nickel/chrome plating for metal surfaces exposed to the molten resin.
- Feed Exxtra Adhere resin into the extruder after LDPE with a similar or higher melt index.
- Before shutdown, completely purge the equipment with LDPE or a suitable cleaning compound.
- Optimize air gap, line speed, coating weight, and temperature profile according to the substrate and laminate structure.
Additives and Regulatory Information
- Antiblock: No
- Slip: No
- Thermal Stabilizer: No
