Flexible Package Lamination with Light Curable Adhesives

Tangent Industries offers light curable adhesives that are ideally suited for laminating films, papers and foils used in product packaging. These applications typically require high T-peel strength, clarity, flexibility, and tear resistance. Tangent adhesives produce strong bonds with PVC, polyethylene, metallized films, polyester, polyamide, and treated polypropylene. (Note: Surface treatment such as corona or plasma will typically enhance adhesive bond strength with all polymeric substrates.) Theses adhesives can be used to seal point-of-purchase display packages, (clamshells). PVC, PET, and RPET can be securely bonded together in a fast, efficient UV light curing process. Products packaged in clamshells sealed with Tangent adhesives gain the ultimate protection from theft, contamination, and environmental damage.

Tangent’s laminating adhesives are robust, moisture resistant, and remain extremely flexible after cure. They are single component and solvent-free. These adhesives cure with low intensity UV or UV/Visible light, and are ideally suited for curing with cooler, monochromatic LED lights. Despite using lower intensity curing systems, cured adhesive surfaces are dry and tack-free.

Laminating adhesives from Tangent Industries can be dispensed manually or using roll coaters, gravure, and flexographic equipment. Several viscosity options are available in this adhesive selection to maximize processing efficiency. If required, Tangent’s adhesives can be formulated with color, making it possible to eliminate additional lamination done solely for the purpose of adding color to the final product.

Please contact Tangent to confirm your product selection and to secure additional application assistance, including samples and process recommendations. In the event that these standard products do not satisfactorily address your performance requirements, Tangent will investigate other solutions that include development of adhesive specifically tailored to the complexity of your application.

*Note: viscosity variations are typically available, or can be formulated, for all listed products. Please inquire with Tangent Applications Engineering for viscosity ranges not shown in the table.
**Note: modifications can be made to most products in order to meet unique performance requirements. Adding fluorescing properties, color, and secondary curing mechanisms are typical examples of minor modifications. Please contact Tangent Applications Engineering to discuss your specific requirements.
