Solvent-Based Adhesives

Solvent-based laminating adhesives contain organic solvents as a carrier for the adhesive resins present in the adhesive system. These solvents are dried after application to facilitate a process known as dry bond laminating, which leaves the active resin system on the substrate to be bonded to a secondary substrate to perform laminations between film and foil materials used to construct flexible packaging.

Solvent-based adhesives constitute some of the oldest chemistries used for flexible packaging applications, and they are still widely used today for several reasons. These adhesives develop good green bond strength quickly, permitting laminates to be postprocessed faster and facilitating shorter turnaround times to complete final packaging. They also create packaging and laminate materials with good appearance and high heat and chemical resistance.

Flexible packaging laminates made with Bostik's solvent-based adhesives can be used in a variety of food packaging applications, including snack food, meat, cheese, frozen foods, chemically challenging foods, and foods that are oily or greasy. Bostik's solvent-based laminating adhesives also cater to multiple FDA regulations concerning food packaging that enable high-demand applications, such as boil-in-bag, ovenable, hot fill, and retortable packaging. They are also used in industrial laminating applications, such as solar control window films, thermal insulation, sailcloth, and photovoltaic backsheets, which bond materials such as plastic films, foils, and fabrics. Bostik's solvent-based laminating adhesive portfolio is one of the broadest and most versatile available in the industry. For more information on these laminating adhesives, explore our options below.
