5. Extrusion-coating

This involves coating a substrate (paper, aluminum, etc.) by extruding a layer of molten polymer with subsequent heat-sealing properties.

Thanks to their excellent adhesion to paper, cardboard, aluminum and many other polymers, ethylene-acrylic ester copolymers are ideal for use either as binders or as sealing layers in extrusion-coating and co-coating processes.

• These qualities offer the following advantages:

  • excellent stretchability ;

  • very good adhesion to a wide range of substrates, including aggressive food products;

  • good adhesion to inks ;

  • Suitable for mixing with polyethylene in all proportions ;

  • excellent welding properties (weldability...
