The laminating step can be done in either batch or automated In-Line modes.
For batch mode, a Clamshell or manual approach is designed for the accurate assembly of precut materials into a specific test strip product. Precut materials and plastic backing are brought together to form a laminated test strip. The Clamshell laminator contains top and bottom vacuum nests to hold test strip materials in place for the lamination process. The nests are customized to the customer's design but are easily interchangeable so other designs can be laminated as well. When the nests are brought together accurate alignment of the laminate is achieved.
For a continuous lamination process, automated lamination is needed. BioDot has evolved a modular lamination system suitable for test formats comprised of multiple layers joined by adhesives.
Each material is fed from adjustable spindles through guides and under a pressure roller to assure complete adhesion to the support backing. The automated system can also be configured with dispensing or cutting technologies.
