Effect of Extrusion Coating Parameters on Activation of a Primed 58 Film, 2002 PLACE Conference Proceedings

In the flexible plastics converting industry, primed films are commonly extrusion coated or laminated with polyethylene or ethylene copolymers. To achieve sufficient adhesion to a primed film, the converter must insure the process parameters meet certain criteria. These criteria include the following extrusion variables:

  • Melt temperature
  • Coating thickness
  • Air-gap
  • Die/nip offset
  • Acid content of the extrudate
    •

    In this paper, we use pilot-line studies to examine the effects of these parameters on adhesion to a film primed with a water-borne extrusion primer.
