Carton Testing

The consistent flow of cartons through form and fill machines is governed by two important parameters; crease quality and frictional forces between carton surfaces.  

Cerulean's carton testing solutions provides a measure of both these parameters. The instrument measures the torque required to fold the carton crease, as well as the coefficient of friction, which is the degree of slippage between the surfaces of adjacent cartons when fed from the magazine of the cartoning machine. Additionally, the instrument records the spring back force, which indicates the materials’ resilience after the crease is folded. This is important as it can effect the way the carton behaves during the forming process and can also cause glued flaps to spring open before the adhesive has had time to cure.
