Method for producing flexible-packaging film

Abstract

A method for producing a flexible-packaging film in which a first substrate and a second substrate are laminated with a reactive adhesive of a polyisocyanate composition (X) and a polyol composition (Y) therebetween includes a two-component separate application step in which a liquid mixture applied to the first substrate and including the polyisocyanate composition (X) and the polyol composition (Y), and a catalyst (Z) formed in a dot pattern on the second substrate are brought into contact with each other to achieve contact-bonding together. The substrates are preferably plastic films, metal vapor-deposition films, or metal foils. As the second substrate, a non-oriented film is preferably employed.
