Henkel has introduced a new cold-seal adhesive designed for barrier-coated paper packaging, aiming to support the transition from plastic flexible packaging to recyclable paper-based structures.
The solution, developed under Henkel’s adhesive technologies portfolio, is designed to enable secure sealing of paper packaging without the use of heat. Cold-seal technology is widely used in packaging applications for products such as chocolate, biscuits, snack foods and ice cream, where heat-sensitive products require fast sealing without thermal exposure.
Traditionally, cold-seal systems have been associated primarily with plastic film structures. Henkel’s newly introduced formulation is intended to address this limitation by enabling similar sealing performance on barrier-coated paper substrates. The development is expected to support packaging manufacturers and brand owners seeking to move toward paper-based alternatives while maintaining operational efficiency.
According to Henkel, the adhesive has been developed to operate on existing packaging equipment commonly used for cold-seal applications. This compatibility is intended to allow converters to transition to paper structures without major modifications to high-speed packaging lines.
The new solution is designed to work with barrier-coated paper materials used in flexible packaging applications where product protection, grease resistance and moisture barriers remain essential. Such formats are commonly used in confectionery, snack and frozen dessert packaging.
In addition to sealing performance, the adhesive has been developed with recyclability considerations in mind. Henkel states that the formulation supports the recyclability of paper packaging structures within existing paper recycling streams, aligning with broader industry efforts to improve packaging circularity.
