Solventless Adhesives

Solventless laminating adhesives contain 100% actives and do not have water or solvent carriers. These laminating adhesives are typically used in flexible packaging applications. They are specifically two-component adhesives consisting of an isocyanate and polyol that are mixed and react to form polyurethane. Solventless laminating adhesives provide packaging converters with cost savings by eliminating the requirement of ovens to remove water or solvent carriers in water-based or solvent-based adhesives.

Solventless laminating adhesives are applied to base substrates like films or foils using solventless laminators that can coat the adhesive via smooth roll transfer coating techniques. Coated substrates are subsequently nipped and bonded to a secondary substrate to make the lamination. These laminations may contain multiple laminate layers used to construct flexible packaging.

Flexible packages made with Dow's MOR-FREE™ and PACACEL™ solventless laminating adhesives are used in an array of packaging applications for food and beverages and meet a broad range of FDA regulations. For example, Dow offers several solventless adhesive options with appropriate compliance for snack food, hot fill, boil-in-bag, microwavable, and frozen food packaging. Dow's solventless adhesives also offer moderate chemical resistance and allow for aggressive fill and fatty food applications. These solventless adhesives are suitable for making laminates using most types of films, foils, and paper.
