One of the greatest challenges in the global packaging industry is replacing plastic-based laminates with materials that fit into existing waste management systems. Henkel’s latest development—a cold seal adhesive technology designed for barrier-coated papers—addresses this exact problem. This new solution allows manufacturers to package heat-sensitive products, such as chocolates and energy bars, in paper while ensuring the resulting pouches are fully recyclable in standard paper waste streams. This move could fundamentally reshape supermarket shelves and significantly reduce global plastic pollution.
The significance of this technology lies in the fact that paper alone lacks the necessary barrier properties (protection against grease, moisture, and aroma) to keep food fresh. Previously, this required plastic coatings that rendered the packaging unrecyclable. Henkel’s new system is fully compatible with the latest water-based barrier coatings.
Quantitative Data and Technical Parameters
Henkel’s press release provides several key figures highlighting the efficiency and market relevance of this new technology:
-
Temperature Sensitivity: The cold seal process is crucial for heat-sensitive goods, as the packaging is sealed at room temperature using mechanical pressure, ensuring the food inside does not melt.
-
Production Speed: The adhesive system is optimized to match the high speeds of modern packaging machinery, capable of handling hundreds of units per minute.
-
Recyclability Certification: The technology is designed to meet the rigorous standards of CEPI (Confederation of European Paper Industries) and OPRL, ensuring that 90-95% of the paper fibers can be recovered during standard re-pulping processes.
-
Material Thickness: The solution is compatible with thin, flexible paper grades, allowing for a reduction in total packaging weight compared to rigid plastic containers.
Synergy Between Barrier Coating and Adhesive
The primary technical hurdle has been that traditional cold seal adhesives did not adhere properly to papers treated with special barrier coatings.
-
Specialized Binding Agent: Henkel researchers developed a polymer composition that ensures stable adhesion even on functional coatings, preventing accidental opening during transport.
-
Contamination-Free Recycling: It is critical for paper mills that adhesives do not cause “stickies” or clogs during the recycling process. The new formula is easily separated from the pulp during fiber recovery.
-
Food Safety: The product complies with strict international regulations (FDA and European norms), guaranteeing that no harmful substances migrate from the packaging into the food.
Sustainability Goals: Henkel’s 2025/2030 Commitments
This development is an integral part of Henkel’s broader strategy. The company aims for 100% of its packaging to be recyclable or reusable by 2025 (where local infrastructure allows).
-
Plastic Reduction: Switching to paper-based flexible packaging directly reduces the reliance on fossil-based plastics in retail.
-
Circular Economy: With paper recycling rates in Europe already exceeding 80%, the introduction of paper-based confectionery packaging can significantly improve the sector’s ecological footprint.
Market Applicability: From Chocolate to Hygiene Products
While the primary focus is on the confectionery industry, the technology’s application is much broader. Henkel experts state that the cold seal solution is suitable for medical devices (such as bandages), hygiene products, and electronic accessories where heat-sealing might damage the contents. Under the initiative “Sealed for Circularity,” Henkel aims to provide brands with a ready-to-implement solution for de-plasticization.
