Is it time to stop using glue and labels on paper?
European packaging regulations are pushing companies to eliminate non-recyclable adhesives, known as 'stickies,' from paper products. German researchers are developing a laser-based sealing process to create adhesive-free packaging.
Why it matters
Reducing adhesive use in packaging is essential for improving recycling efficiency and meeting strict new environmental sustainability standards.

While paper or cardboard packaging might on its own be recyclable, the presence of a label, a seal or a coating can negate that.
That's because non-recyclable adhesives, or "stickies" as they are known as in the industry, can cause damage to recycling machinery, make the resulting batch of recycled paper inferior, or even cause a batch of paper to be recycled to be rejected, according to scientists at NC State University.
And that's a shame as paper is one of the most recycled materials in Europe - with around 74% of paper and board consumed in 2024 being recycled.
And European authorities are spurring firms to do better.
