Flexible packaging is usually made of a composite of different laminated films, with the individual structure and material composition depending on the intended use of the packaging. Duplex, triplex and quadruplex films can be used.
Adhesives offer significant benefits over other mechanical connecting systems in the industrial production of folding boxes or other corrugated cardboard packaging. They are applied automatically with gluing robots or pass-through machines, enabling short cycle times and low error rates. The choice of adhesive plays a key role. Hotmelts must be able to be applied with absolute precision and without stringing, dispersions must be drip-free, and both systems have to have a high initial strength to ensure high output.
