Meeting highest standards in food and operator safety with Ultra Low Monomer Technology for flexible laminates
Specifically designed for film-film and film-foil laminates which have to show an increased resistance to aggressive fillings or hot water during boiling procedures, Ultra Low Monomer adhesives contain only a minimum amount of free isocyanate monomers and thus reduce from the outset the amount of PAA that could be formed. Loctite Liofol LA 3712 / LA 6222 is one of these adhesives. It is a 2-K solvent based laminating adhesive for medium to medium-high performance that is factually PAA-free right after lamination for a large variety of laminates and thus sets a new industry benchmark in food safety.
Low temperature adhesives increase safety and improve sustainability
Henkel’s new all-rounder adhesive Technomelt Cool 190 is an adhesive with a high adhesion potential and thermostability used in a wide range of paper boards. The low processing temperature of only 120 to 150 degrees Celsius leads to a significant improvement in operator safety. Beyond minimizing potential injury risks for operators, the lower application temperature of Technomelt Cool 190 significantly reduces the energy consumption in the packaging process.
Assuring high lamination quality “on the run”
Henkel is also introducing a new inline, contactless and non-destructive coating weight measurement system for flexible laminates: LIOSCAN. This system can be retrofit in almost all common laminating machines. It significantly improves reliability of operations by immediately indicating any deviation from the specified coating weight, minimizing risks of potential claims and reducing material waste at the same time. For the measurement, Henkel’s innovative system is equipped with an automatically oscillating infrared sensor moving along the film sideways without contact to the material. This sensor measures the isocyanate content, thus achieving highest coating weight precision. The system covers the full width of the film not only for transparent but also for printed or metallized films and aluminum of various thicknesses.
