Mondi recently announced that it has developed what it says is the world’s first sustainable polycoated kraft (PCK) paper release liner. Release liners, which carry and protect pressure-sensitive adhesive (PSA) products, are currently often discarded once the PSA products are used. Mondi reports that its NextLiner uses a recycled base paper with a coating made from renewable resources. Using recycled fibers and renewable materials can have a positive impact on the environmental footprint of NextLiner, which can be used in graphic arts, tapes, and other industrial applications.

“Our goal is to be sustainable by design, so we have worked on innovating environmentally responsible NextLiners that support our customers’ sustainability goals,” said Stefan Schönberger, head of Product Sustainability. “Using recycled fibres and renewable resins takes us one step closer to making the PSA supply chain more sustainable.”

The use of release liners continues to grow. According to AWA’s “Annual Review Global Release Liner Market 2020,” polyolefin coated paper consumption is around 9 billion m2 per year, with a market share of 16% of the total release liner market. This makes environmentally responsible alternatives in the sector all the more important.
