Definition
Bonding two substrates by extruding molten resin between them, acting as both adhesive and functional layer.
Applications
- PET/PE or paper/PE laminates
- Heavy-duty industrial laminates
- Some foil laminations
Benefits
- Strong bonds
- High throughput
- Excellent structural integrity for demanding packs
Industry Examples
- Medical: durable laminates for secondary medical overwraps that must resist tearing.
- Industrial: reinforced laminates for abrasive products and long transport cycles.
- Electronics: bonds foil and PE layers to create high-barrier laminates for semiconductor moisture protection packaging.
FAQ
Q: When is extrusion lamination preferred?
A: For robust bonds and high-speed production.
Q: Does it require solvents?
A: No—resin acts as the bonding medium.
