The LCT combines three tests in one instrument – crease strength, box forming force and spring-back with optional friction testing for the ultimate carton analysis and quality assurance.

The Laboratory Carton Tester (LCT) solution 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 cartooning machine. Additionally, the instrument records the spring back force, which indicates the materials’ resilience after the crease is folded. A great attribute for a carton tester as this 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.

End users gain from an improved running efficiency on form and fill lines while converters gain from a reduction in rejected cartons.
