• Acrylic Acid Content: 9.7%
• Melt Index (190℃/2.16kg): 8.5 g/10min
• Density: 0.938 g/cm3
• Melting Point: 98℃

Main Applications

• Extrusion coating
• Aluminum foil lamination
• Adhesive bonding resin
• Multi-layer flexible packaging structure
• Tie layer between PE and EVOH resins
• Plastic-aluminum composite, cosmetic tubes and packaging laminates

Product Features

1. Outstanding adhesion to aluminum foil, metal, PE, EVOH, PA and paper; no primer needed for lamination.
2. Good thermal sealing property, low temperature heat seal and high temperature cooking resistance.
3. Stable fluidity, suitable for high-speed extrusion coating and co-extrusion lamination.
4. Excellent toughness, aging resistance and chemical resistance, keeping bonding stability in humid and cold environment.
5. Ideal compatibilizer and adhesive layer for multi-layer barrier packaging structures.

Recommendation

SK EAA 3004 is the preferred equivalent of Primacor 3004, perfectly suitable for all walks of extrusion coating, aluminum lamination and adhesive tie-layer projects in flexible packaging industry.
