Hard to recycle packaging? This glue could let plastics peel apart on cue

Newcastle University engineers are at the forefront of adhesive technology that promises to change how we recycle. They have developed a reversible glue that sticks things together like any other glue but can debond on demand. The glue's reversible nature means it can be used in a multitude of applications, from laminates to bottle labels. Dissimilar materials that are glued together can be easily separated, enabling their reuse, repurposing, or recycling.
