中文Herma has introduced Linerless Plus (400), a linerless label material that uses the company’s multi-layer pressure-sensitive adhesive 62Dps for the first time in this product range. The combination is designed to expand the application window for linerless labels by delivering stronger adhesion without the process compromises that have historically limited the technology.
The Linerless Promise and Its Limits
Linerless labels have long been attractive for sustainability and cost reasons. By eliminating the siliconized release liner, converters reduce material waste, lower disposal costs, and increase the number of labels per roll. Fewer roll changes mean less downtime, and lower shipping weight reduces freight emissions. The environmental case is clear.
However, conventional linerless materials have faced practical constraints. To prevent adhesive bleed and the buildup of adhesive on converting and cutting equipment, many linerless products use adhesive-free zones. Those zones limit the adhesive coverage and can make the labels unsuitable for applications requiring high initial tack, strong final adhesion, or reliable performance under mechanical stress or low temperatures.
How the 62Dps Adhesive Changes the Equation
The 62Dps adhesive uses a two-layer structure that Herma says prevents bleeding without requiring adhesive-free zones. Because the adhesive can be applied across the entire label surface, the labels achieve stronger adhesion, making them viable for demanding applications such as logistics, shipping, and dispatch processes. These environments often involve rough cardboard surfaces, friction, and temperature variations that test the limits of standard labels.
Markus Mateescu, head of silicone development at Herma, noted that the multi-layer structure enables adhesion and optimized converting properties to coexist. In the past, improving one often came at the expense of the other, which reduced process reliability. The 62Dps formulation is intended to break that trade-off.
Market Relevance
The Linerless Plus launch arrives as brand owners and regulators continue to push packaging sustainability. Linerless labels align with those goals by reducing material use and waste. The challenge for suppliers has been to make linerless labels perform in a wider range of applications. By pairing linerless construction with a high-performance adhesive, Herma is targeting customers who want the sustainability benefits without sacrificing adhesion or process stability.
For label converters, the development matters because it could open new application areas for linerless production. If linerless labels can now handle tougher substrates and conditions, converters may be able to replace traditional labels in segments that were previously off-limits.
