Crease and Board Stiffness Tester (CBT1)

• Measure crease recovery (spring back)
• Measure board stiffness
• Instant display of crease to board stiffness ratio
• Measure whole carton opening force

The CBT1 Crease & Board Stiffness Tester gives board manufacturers, printers and packing companies the ability to predict the ‘runability’ of a sample board or finished carton.

The instrument measures crease folding force at 90°, board stiffness at 15° and requires no external software for operation. It automatically calculates the crease to board stiffness ratio for instant indication as to whether the material will run correctly on a high speed packaging machine.

Features

Independently operated jaws are rotated through pre-defined angles, 90º for crease recovery and 15º for board stiffness.

Automatic Dwell Time

15 second measurement delay to eliminate operator variability (according to BS 6965).

Automatically Calculates Stiffness / Crease Ratio

Results calculated and displayed instantly on screen. No additional software is required for data analysis. BS 6965 advises that optimum running cartons should have a ratio between 1.5 and 3 (machine direction) and 3 and 7 (cross direction).

Automatic Calculation of Statistics

Full statistics are displayed for both crease recovery and board stiffness

Data Handling

Easy printing of results to Hanatek label printer; all results are date and time stamped.

Sample Preparation Options

One Step Sample Preparation

Sample preparation is easy with the Hanatek universal sample cutter.

The crease to be tested can be cut with a single process therefore eliminating errors associated with traditional crease sample preparation (usually a 3 step process).

Multiple test pieces can be cut from the same sample saving valuable test time. Hanatek offers custom cutting dies to suit most packaging applications, e.g. friction, tensile, grammage, rub / abrasion.
