Packaging Automation has helped to develop a revolutionary new laser sealing and inspection system for food packaging

The new sealing system, which can be used for ambient or chilled oven-ready meal products, is designed to seal lidding film to food trays using a laser without the need for conventional tooling. PA claims that the new method will bring numerous important benefits to the food industry including reduced tooling costs, improved seal quality and less wastage. 

The new sealing system, which can be used for ambient or chilled oven-ready meal products, is designed to seal lidding film to food trays using a laser without the need for conventional tooling. PA claims that the new method will bring numerous important benefits to the food industry including reduced tooling costs, improved seal quality and less wastage. The new equipment was developed as part of a Defra sponsored FoodLink project. Multiple tray shapes can be processed on a single production line, and fast product changeovers can be achieved without resetting the sealing machinery. In addition, the lidding film is cut by the laser beam once the seal has been made.
