 Extrusion
coating is the coating of a molten web of synthetic resin on
to a substrate material. It is a versatile coating technique
used for the economic application of various plastics, notably
polyethylene, onto cardboard, paper, aluminum foils, cellulose
or plastic films. The actual process of extrusion coating
involves extruding resin from a slot die directly onto the
moving web which is then passed through a nip consisting
of a rubber covered pressure roller and chrome plated cooling
roll. The latter cools the molten film back into the solid
state and also imparts the desired finish to the plastic
surface.
 The market for extrusion coating includes
a variety of end-use applications ranging from flexible packaging
to commercial applications. PLI’s extrusion and laminating
capabilities is up to 85 inches with double sided texturing
and embossing.
