Tray forming is a technology used to reform cartonboard into hollow shapes with one or several indentations. This technique is commonly used in the production of plates, bowls and other similar cartonboard products, primarily for the food sector. The source material for tray forming is typically cartonboard that is plastic coated on one side. During the process, the cartonboard is folded and glued into the desired shape, and the final product is then placed under pressure to ensure that the adhesive cures properly. Tray forming technology is an efficient and cost-effective way to produce a wide range of cartonboard products of various shapes and sizes.
