Abstract
A laminated film for attachment of printhead integrated circuits to an ink supply manifold. The film has a plurality of ink supply holes defined therein and film comprises: a central polymeric web; a first adhesive layer for bonding a first surface of the film to the ink supply manifold; and a second adhesive layer for bonding a second surface of the film to the printhead integrated circuits. The central polymeric web is sandwiched between the first and second adhesive layers. A first melt temperature of the first adhesive layer is at least 20° C. less than a second melt temperature of the second adhesive layer.
