HERMA Unveils HERMAsuperTack, a Resin-free Adhesive for Labels

Published on 2016-04-01. Author : SpecialChem

A world premiere in the field of low-migration adhesives: HERMA introduces a completely resin-free adhesive for labels that require extremely strong initial tack. Since migration is determined by the adhesive’s resin content, the new HERMAsuperTack (63Vst) offers especially low migration levels. It features correction factor 2, and thereby reaches the unconditional approval for dry, moist, and fatty foods. “Thereby, we are coming closer than ever to the zero migration benchmark”, says Dr. Ulli Nägele, HERMA’s head of research and development. Due to that and its excellent initial tack, HERMAsuperTack is ideally suited for labels that are applied to whole sausages or raw ham without a barrier layer made of film.

Since adhesives owe most of their good adhesive properties to resins, it had been nearly impossible to dispense with them up to now. “The lower the resin content, the lower initial tack and final adhesion, especially on films”, explains HERMA’s head of research and development. “But by applying our multi-layer technology, we were able to develop an adhesive that does enable us to dispense with resins – without any compromises.”

Great temperature resistance

On the contrary: its excellent initial tack makes HERMAsuperTack ideally suited for problem-solving when it comes to films and moist, fatty, or slightly dirty surfaces – its range extends well beyond food labelling. It makes the most of its advantages at near-freezing temperatures combined with condensation: “The adhesive received top marks in tests at 0 and +2 °C on polar and non-polar surfaces”, says Dr. Nägele. “Even at temperatures below minus twenty degrees, it does not lose its tack.” But that is not all: due to its temperature resistance, HERMAsuperTack is also suitable for foodstuffs that have been recently heated, such as boiled chicken. In such cases, there is usually a great amount of heat and moisture beneath the packaging film. Its excellent tack also predestines the adhesive for three-dimensional, irregularly shaped surfaces, ranging from shrink-wrapped raw ham to pre-packaged poultry cuts.

Excellent processability

Despite outstanding tack and optimal migration levels, HERMAsuperTack can be processed as easily as conventional dispersion adhesives. The global innovation is available in combination with the label materials HERMAtherm M (912) and HERMAwhite super (240).


Located in Filderstadt near Stuttgart (Germany), HERMA GmbH is a leading European specialist in self-adhesive technology. In the 2015 fiscal year, the HERMA Group generated sales of approximately € 300 million with 940 employees in three divisions – Self-adhesive Materials, Labels and Labelling Machines. The export ratio exceeded 60 %.
