What do shower gel bottles, soccer cleats and an airplane have in common? Nothing? Think again: Glue is what holds them together. Now, you’re probably saying to yourself: “In sports shoes and cosmetics, sure – but in cars?” In fact, the automotive industry is increasingly replacing metal rivets and screws with adhesives, because modern lightweight construction processes depend on them. Adhesive technologies can work wonders in their industrial applications, which range from meter-high wind turbines, through razor-thin touchscreens and all the way to the inner workings of our smartphones.
Mankind discovered the power of glue early on in its history. The Neanderthals, for instance, used birch tar to make tools. Over time, the effectiveness of adhesives improved and the number of possible applications grew proportionally to the emergence of new technologies.
Henkel arrived in the adhesives business by an accident of history: In reaction to the supply bottlenecks that occurred in the aftermath of the first World War, Hugo Henkel tasked his chemists with developing their own glue for sealing cartons of Persil.
Today, the company is the global market leader and has expanded its activities well beyond conventional glue. Collaborating with various industrial partners, Henkel’s Adhesive Technologies business unit develops high-impact material solutions that act as invisible helpers to make everyday products lighter, smarter and more efficient. Covering sealants and functional coatings in addition to adhesives, the company's technologies support multiple digital applications, contribute to making electromobility a reality and even help to enable food safety.
Pritt pioneers with plastic-free blister packs made from recycled paper
As first adhesive manufacturer worldwide Henkel will introduce plastic-free blister packaging for its broad portfolio of consumer adhesives globally, starting with the Pritt glue sticks in early summer 2022. The new plastic-free blister packs are made from minimum 85 percent recycled paper and are fully recyclable. This solution will contribute to a reduction of 1,000 tons of plastics annually. The new packaging concept is in-line with the company´s sustainability ambition and packaging targets 2025 and aims to further enhance the recyclability of products towards a circular economy.
