Perfecting lamination for babies' nappies: Nappies present a number of significant engineering challenges

摘要

While possibly not at the forefront of many engineers' minds as a cutting-edge product, babies' nappies in fact present many challenges, as they have to both perform well in terms of their sanitary properties while not causing irritation to babies' sensitive skin. Italian manufacturer A Celli turned to adhesives manufacturer Henkel for help in one of the first stages of the manufacturing process, bonding a non-woven material to a plastic film to make a laminate. This involves laminating sheets up to 8m wide, running through machines at a rate of more than 100m/min, and requires a high level of bonding accuracy.
