What does the CFA measure?
The Hanatek Carton Force Analyser (CFA) 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 has pre-loaded test instructions that ensure samples are tested to international standards.
Measures the stiffness of the board sample to ISO 2493. The stiffness of the sample is measured twice, once with the printed side of the carton facing forward and the second time with the printed side facing to the rear.
The resultant force is displayed in N, gF or mN. The average of the two measurements is calculated as well as the Min, Max and standard deviation on a multiple sample test.
Measures the crease recovery to BS 6965. During the test, the Instrument will fold the crease under test through the preselected crease angle and hold it there for a pre‐determined number of seconds. It will then measure the force exerted on the crease as the instrument rotates the sample throughout the desired test angle.
The peak force is displayed as well as the angle that this force was reached. The resultant force is displayed in N, gF or mN. The average measurement is calculated as well as the Min, Max and standard deviation on a multiple sample test.
Rounded corner crease resistance: Rounded corner creases can be tested on the CFA (requires additional jaw).
During the test the Instrument will un‐fold the crease under test through the preselected angle. The resultant force is displayed real time on the screen as the sample is rotated through the preselected test angle.
At the end of the test the resultant peak force is displayed in N as well as the energy in mJ required to bend the sample.
