Henkel Expands Sustainable Packaging Portfolio with Cold Seal Technology for Paper-Based Flexible Packaging

Loctite Liofol CS 7106 RE enables a secure seal without heat exposure and thus the production of recyclable barrier-coated paper packaging structures.

(IN BRIEF) Henkel has launched Loctite Liofol CS 7106 RE, a cold seal coating specifically developed for barrier-coated paper packaging, enabling recyclable paper alternatives to plastic packaging for products such as snacks, confectionery and ice cream. The solution allows manufacturers to seal packaging without heat, preserving product quality while supporting efficient high-speed production. Designed as part of Henkel’s recycling-compatible RE product range, the coating provides strong adhesion and consistent performance and has been verified as compatible with mechanical paper recycling processes. The product responds to increasing regulatory requirements such as the EU Packaging and Packaging Waste Regulation and growing consumer demand for sustainable packaging, helping manufacturers transition to paper-based packaging solutions that support circular economy goals.

(PRESS RELEASE) DÜSSELDORF, 26-Feb-2026 — /EuropaWire/ — Henkel has introduced Loctite Liofol CS 7106 RE, a new cold seal coating developed specifically for barrier-coated paper packaging, marking a significant step forward in the shift from plastic-based packaging to recyclable paper alternatives. The new solution enables packaging for products such as snacks, confectionery and ice cream to be sealed efficiently without heat, supporting the development of circular and recycling-compatible packaging designs.

The introduction addresses the growing industry movement toward paper-based packaging solutions as companies respond to stricter regulatory requirements and rising consumer demand for recyclable materials. Regulations such as the European Union’s Packaging and Packaging Waste Regulation (PPWR) and increasing sustainability expectations are accelerating the transition to paper-based packaging. Industry data indicates that more than 70 percent of consumers worldwide view recyclable packaging as important or desirable.

Loctite Liofol CS 7106 RE is the first cold seal coating in Henkel’s portfolio developed specifically for use with barrier-coated paper substrates. The product allows packaging manufacturers to create secure seals without applying heat, helping protect heat-sensitive products while enabling reliable and efficient production of recyclable packaging structures. The solution is suitable for a range of applications including snack and confectionery packaging as well as secondary packaging such as collection cards that previously relied on plastic materials.

The new cold seal coating is part of Henkel’s RE product range, which includes adhesives and coatings designed to support recycling-friendly packaging structures. These solutions are developed to ensure that packaging materials can be efficiently recovered and reused within recycling systems.

Loctite Liofol CS 7106 RE provides a durable and permanent seal with strong adhesion characteristics and consistent performance during production. The coating is supplied ready for application and can be used across a wide range of paper weights while maintaining stable processing performance even at high production speeds. The formulation also demonstrates reliable ageing properties and tolerates typical paper-related contaminants that could otherwise affect sealing quality.

Recyclability testing conducted by an accredited certification body confirmed that the coating is compatible with mechanical paper recycling processes, making it suitable for packaging designs that must comply with current and emerging recyclability standards.

The new solution is designed to integrate easily into existing high-speed packaging lines, enabling manufacturers to adopt paper-based packaging without major process modifications. This is particularly important for industries such as snacks, confectionery and ice cream production, where cold seal technology is widely used because sealing without heat helps maintain product quality and aroma while reducing stress on packaging materials.

By combining cold seal technology with modern barrier coatings, manufacturers can create packaging structures that provide product protection while remaining compatible with recycling systems.

Cagri Turkmen, Market Strategy Manager Flexible Packaging at Henkel, stated that Loctite Liofol CS 7106 RE provides verified cold seal performance on barrier-coated paper while enabling packaging solutions that support circular economy goals and meet demanding standards for safety and production stability.

As recyclable paper packaging becomes increasingly important under evolving regulatory frameworks such as the PPWR, Loctite Liofol CS 7106 RE is designed to support compliance by ensuring that barrier-coated paper packaging remains recyclable. The solution provides packaging manufacturers and brand owners with a practical pathway to develop high-performance packaging that aligns with future sustainability and regulatory requirements.
