Abstract
In the extrusion coating process, anchorage of the extruded film to the substrate (i e , paper, cloth, foil ) is very essential An improper bond between the two surfaces can sometimes lead to catastrophic failures and product non-func tionality.
Because extrusion coating process conditions—polymer melt temperature, lami nating mp pressure, air gap, film (coating) thickness, as well as substrate composi tion—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 extru sion melt temperature and film (coating) thickness are the two factors that pre dominantly affect the degree of mechanical anchorage between the film and woven fabric
