<p>The present invention is directed to laminating methods for producing a multiple-layered packaging laminate from at least two films without the necessity of utilizing separate adhesives therebetween. The laminating methods of the present invention in general include the steps of detackifying the surface only of a partially cured film, and then storing the film on a roll. Thereafter, the detackified surface is retackified, and then the retackified film is laminated by known techniques to a second film. In alternative embodiments, the second film may also be processed according to the above detackifying and retackifying procedures prior to such lamination. The practice of the methods of the present invention permit the packaging producer and other laminated film users to assemble the laminate of the present invention at the point of use. Such laminates are formed in preferred embodiments for 100% solids films and without the necessity for solvent-containing adhesives or other solvent-containing materials.</p> |
