Carton Force Analyser

The Hanatek Carton Force Analyser measures the forces that limit the running speed of folding box board packaging. By measuring the stiffness of the substrate and crease bending resistance the user can optimise cartons for faster running and packaging speeds.


The instrument allows individual creases to be analysed identifying problem areas in packaging design or manufacture. Industry research indicates that the packaging speeds of pre-glued skillets is governed by the energy required to open creases. The Hanatek CFA is the first instrument to isolate and accurately measure this key parameter The instrument measures: Bending resistance, bending moment, bending stiffness, crease recover stiffness, crease folding force, crease opening force.

Who measures board stifffness and crease resistance?

Board stiffness and crease resistance are important measures that indicate how a finished carton will run on an automated glueing, filling or packaging line. Substrate manufacturers, printers, converters and any manufacturer who fills or packs products in cartons can use this measurement to optimise production.

QA departments use these instruments to check the running attributes of finished cartons are prior to conversion and filling, reducing lost production time from slow running or difficult to convert packaging.
