Often invisible and yet irreplaceable in many areas of the world of packaging: glue. The desire for more sustainability doesn't cast the same limelight on adhesives that it shines on packaging, which is far easier to notice for consumers. But here, too, much can be done to reduce carbon emissions and optimise production to be more circular.
As of now, adhesives are often irritants in the process of recycling. Whether they make sure that labels stay on paper packagings or form a sticky layer between the tray and the cling foil around a wrapped cheese: The recyclability and the production process of the adhesive must feature in future thinking about sustainability.
One example of how to achieve this is German adhesive manufacturer Jowat. The company has recognised the demand for sustainable adhesive solutions and adapted their own portfolio to meet it. With the “Green Adhesives” series, the glue manufacturers offer both adhesives with a large content of bio-based raw materials as well as very energy efficient, process-optimised and food safe solutions for gluing.
