With Technomelt Supra ECO, Adhesive Technologies has developed a new hotmelt adhesive for packaging containing up to 98 percent* bio-based raw materials. Until now, conventional hotmelt adhesives for packaging have usually contained no more than 50 percent bio-based raw materials. Previously, it was not possible to increase this share, as it severely impacted customers' production processes.
Experts at Adhesive Technologies have developed a solution for these issues. "With the ability to use more bio-based raw materials without making sacrifices in manufacturing, we were able to develop an innovative technology that will continue to lead our industry into the future," says Adrian. And one that helps customers reduce their environmental footprint, too.
The focus on renewable materials is also visible in other areas: As part of a broad portfolio of adhesives, Henkel also supports customers in the production of sustainable paper straws. Thus, contributing to the gradual replacement of plastic straws with the more sustainable option. In addition to sustainability, the health of consumers is of utmost importance to Henkel. The water-based adhesives meet the highest food safety standards.
Safety is also a priority when it comes to medical devices. More and more people are using digital devices to monitor their vitals in real-time. In the process, the devices are becoming smaller and more user-friendly so they can be easily worn on the body. This presents device manufacturers with new challenges in development and assembly, as the components are becoming more complex in shape. At the same time, the requirements for flexibility and functionality are increasing. In the case of wearables (electronic devices that are worn on the body or integrated into clothing) every single component – from the internal circuit board level to the housing – must be protected.
Solutions by Adhesive Technologies are used, for example, in digital devices that help monitor the blood sugar levels of diabetics. The monitors are attached to the patients’ skin, which makes life easier by eliminating the need to take regular blood drops from their fingers. In the past, the adhesive that bonds the plastic components of the monitor together often contained isobornyl acrylate, an ingredient that triggers allergic reactions in some people.
Henkel experts have succeeded in developing adhesive technologies without isobornyl acrylate. "Our adhesives are dermatologically safe and free of allergenic ingredients," explains Thomas Silva, Global Business Development Manager for Medical Wearable Device Solutions in the Adhesive Technologies business unit. The goal, he says, is to optimize diagnostics and improve patient outcomes. "We have succeeded in doing exactly that with this product. It is a good example of how our innovative adhesive solutions make applications in medical technology safer and more reliable," Thomas emphasizes.
