Co-Extrusion Coating of Woven Fabrics, 1990 Polymers, Laminations & Coatings Conference Proceedings
In the extrusion coating process, anchorage of the extruded film to the substrate (i.e. paper, cloth, foil...) is very essential. Improper bond between the two surfaces can sometimes lead to catastrophic failures and product non-functionality.
Since extrusion coating process conditions -polymer melt temperature, laminating nip pressure, air gap, film (coating) thickness, as well as substrate composition - play a major role in determining how successful this coating step would be, their effects on the degree of “physical” adhesion is investigated.
Data from the aforementioned process investigation strongly reveal that the extrusion melt temperature and film (coating) thickness are the two factors that predominantly affect the degree of mechanical anchorage between the film and woven fabric.
