Henkel launches bio-based hot melt adhesive for packaging

Henkel Adhesive Technologies now combines both technologies for the first time: The hot melt Technomelt Supra 079 Eco Cool is a bio-based product that combines 49% directly bio-based raw materials with 30% ISSC-certified mass-balanced material. It bonds folding cartons, trays and wrap-around packaging at a processing temperature that is up to 40°C lower.

With the new Technomelt Supra 079 Eco Cool hot melt adhesive, Henkel combines the advantages of its proven Technomelt Supra Eco and Supra Cool series. With the Supra Cool range, the manufacturer offers a portfolio of hot melts that lead to lower energy consumption thanks to reduced application temperatures. The Supra Eco range uses bio-based materials for a more sustainable packaging design. By combining both technologies in the latest development, companies can optimize the sustainability of their packaging at two points in the value chain – raw materials and processing.

Technomelt Supra 079 Eco Cool is a bio-based product that has a direct bio-based content of at least 49% and combines this with 30% ISCC-certified mass-balanced material. The ISCC certification allows to correctly allocate the volume of certified and non-certified material to the product. At the same time, the application temperature can be reduced by up to 40°C. In addition to lower energy consumption, there are advantages for the operating personnel: these include a lower risk of burns and reduced exposure to vapors and volatile substances.

By using Technomelt Supra 079 Eco Cool, companies can reduce their CO₂ emissions by up to 32% compared to a premium polyolefin-based hot melt. This saving corresponds to around 7,500 kilograms of CO₂ per year, assuming an adhesive consumption of 7 tons per year. The calculation is based on a cradle-to-gate analysis of the product’s carbon footprint, excluding the use phase and end-of-life emissions. Like many non-bio-based adhesives in the Henkel portfolio, the adhesive is compatible with the paper recycling process and is certified as such by cyclos-HTP.
