Rising CO2 emissions, stricter regulations and increased consumer expectations has led to bio-based materials and low-temperature adhesives becoming the ideal choice for sustainable packaging. Henkel Adhesive Technologies has combined both technologies with the new Technomelt Supra 079 Eco Cool.
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 40ºC lower than application temperature, allowing for lower energy consumption, as well as a reduced risk to burns and reduced exposure to vapours and volatile substances.
With the Supra Cool range, Henkel offers a portfolio of hot melts that lead to lower energy consumption thanks to reduced application temperatures. While the Supra Eco range uses bio-based materials for a more sustainable packaging design. By combining both technologies in the latest development, users can optimise the sustainability of their packaging at two points in the value chain – raw materials and processing.
“By using Technomelt Supra 079 Eco Cool, companies can reduce their CO2 emissions by up to 32 percent compared to a premium polyolefin-based hot melt. This saving corresponds to around 7,500kg of CO2 per year, assuming an adhesive consumption of 7 tonnes per year,” Henkel explains, a calculation 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 by cyclos-HTP. The cyclos-HTP institute has developed a scientifically based catalog of requirements and assessments for testing and verifying the recyclability of packaging and goods.
"With Technomelt Supra 079 Eco Cool, we are addressing several trends and challenges in the packaging industry," says Nele Gering, sustainability manager Europe at Henkel Consumer Goods Adhesives. "Increasing regulations and consumer preferences for sustainable packaging practices and materials are putting pressure on companies to innovate in the area of sustainable packaging design. We are pleased to launch a product that is particularly suited to responsible companies – it reduces CO2 emissions, can improve process efficiency and is fully compatible with the paper recycling process."
