For the development of new structures by extrusion lamination, the question of finding suitable adhesives often remains a tricky limitation: lack of versatility in adhesion, lack of flexibility in processing, difficulties in purging, need of primers are some of the issues that converters would like to overcome. To these questions, the original chemistry of ethylene – acrylic ester – maleïc anhydride terpolymers brings attractive answers. Versatile in processing and in adhesion, these functional polymers are considered with a growing interest in the very demanding industry of extrusion lamination. The first part of this presentation will focus on their properties, their processing, and the new solutions that they offer to the lamination industry. The second part deals with a topic of common interest for many people involved in multilayer design or manufacturing: understanding peel strength measurements, particularly the influence of multilayer structures.
