A new rig has been developed to allow manufacturers of food tins and beverage cans to measure the force needed to lift the ring pull and open the container. This new development could signal the end of consumer frustration with trying to open metal packaging that is too stiff, or where the ring pull detaches from the lid.
Understanding and quantifying the force needed to use a ring pull is vital for both packaging manufacturers and their customers to ensure safety, functionality and consumer experience.
