Abstract:
A method for producing a multi-layered foil laminate comprising two substrates bonded together to form a multi-layered foil laminate having at least two layers, each layer printed on one outer side with indicia wherein a first layer comprises a first plastic film material and having printed indicia on a first side and a second layer comprises a second plastic film material having a first surface adhesively secured to a facing first surface of a metal foil, said metal foil having printed indicia on a second surface, wherein said first and second layers are bonded together by a heat activated adhesive on facing surfaces of said plastic film materials of said two layers and by bonding a further layer comprising a third plastic film material on said bonded first and second layers, said method comprising the steps of:a) printing indicia on a first surface of a first plastic film material through lithographic offset halftone printing; b) applying spray powder to printing ink of said printing indicia on said first surface of said first plastic film to provide a separation layer as a first layer; c) adhesively securing a second plastic film material first surface to a facing first surface of a metal foil by a heat activated adhesive, said metal foil of an overall thickness of from about 0.05 mm to about 1.5 mm; d) printing indicia on a second surface of said metal foil through lithography offset halftone printing; e) applying spray powder to printing ink of said printing indicia on second surface of said metal foil to provide a separation layer as a second layer; f) collating and bonding together said first layer on second surface of said first plastic film material and said second layer on second surface of said second plastic film material wherein said first and second layers are collated and bonded together on facing surfaces of said plastic materials of said two layers to form a first embodiment; g) applying a third plastic film material as an exterior transparent plastic film over said first embodiment to form a multi-layered second embodiment; h) applying heat and pressure to said second embodiment to form a multi-layered plastic film metal foil laminate; i) finishing said multi-layered plastic film metal foil laminate by severing said multi-layered plastic film metal foil laminate into pre-determined sized segments, each segment having printing located on each outer side.
