Form Fill Seal: How it Works

Form fill seal production lines for rigid packaging applications are designed to combine multiple processes into one system. Integrating thermoforming, filling, sealing, and die-cutting into one process enables the form fill seal lines to efficiently form containers that are then precisely filled with the target food product, such as yogurt and pudding, then sealed ready for distribution.

The process starts with a large reel of rigid rollstock which is heated by contact plates to become formable. This sheet then moves to the forming station where cups are formed through the traditional thermoforming process. Remaining in the “web”, these cups move to the filling and sealing stations, where the cups are filled with product and sealed with lidding film. Next, the filled and sealed cups advance to the die cutting station, where they are cut from the “web” into finished products, such as multipacks, and proceed to automated secondary packaging lines for final, retail-ready packaging with minimal labor.
