Henkel has launched Loctite Liofol CS 7106 RE, which it claims is the first cold seal solution specifically designed for barrier-coated paper packaging in the Henkel portfolio.

Formulated specifically for barrier-coated paper, Loctite Liofol CS 7106 RE ensures process-reliable production of recyclable packaging structures, creating a secure seal without heat exposure. It thereby supports manufacturers to transition toward sustainable packaging concepts. The product is suitable for applications in the snack and confectionery segments and also for collection cards or other secondary packaging that previously required plastic structures. The solution is part of Henkel’s RE range, a product family of adhesives and coatings specifically developed for recycling-compatible packaging design that supports the reutilization of materials.

Durable seal with recycling compatibility

Loctite Liofol CS 7106 RE provides a strong, permanent seal with adhesion properties and high-quality application, even at high line speeds. The cold seal coating is press-ready, ensures stable application on a wide range of paper grammages, and boasts ageing properties. It also tolerates typical migrants from paper substrates, thus preventing process-related fluctuations in performance. The product is compatible with mechanical paper recycling.

Process reliability and heat-sensitive product segments

The new solution offers consistent cold sealing performance on barrier-coated paper structures with hassle-free processing on existing high-speed lines. This is particularly important in the snack, ice cream, and confectionery industries, where packaging contents are sensitive to heat and the cold seal technology is essential. As sealing is achieved without thermal exposure, product quality and aroma are preserved while the mechanical stress on packaging material remains minimal. When combined with modern barrier systems, this process produces functional, recycling-compatible paper structures.

“With Loctite Liofol CS 7106 RE, Henkel delivers attested cold seal performance on barrier-coated paper and, consequently, packaging solutions that meet the requirements for a circular economy and the high demands for product safety and process stability,” said Cagri Turkmen, market strategy manager, flexible packaging at Henkel.
