Who measures board stiffness 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 fill or pack products in cartons can use this measurement to optimise production.

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

Carton manufacturers and designers can use a Crease and Board Stiffness Tester with a Hanatek Carton Crease Proofer to test different substrate and crease combinations in the laboratory without committing valuable production time.

Measurement Benefits

  • Manufacture consistent product
  • Increase production
  • Increase product quality
  • Increase packaging speed
  • Optimise production process

Why is board stiffness and crease resistance testing important?

A printed sheet or roll of carton board is die-cut and creased into a preformed carton board blank. This blank is then often glued and erected before being filled on an automated packaging line, these processes all interact mechanically with the blank to convert it into a three dimensional object.


Dimensional Strength

It is also important that the finished material has the required dimensional strength to hold and protect the packaged product.

Stiffness and Crease Resistance

Board stiffness test and crease resistance testing are important parameters that help determine maximum conversion and packaging speeds, they can also be related to the final dimensional stability of the finished product.

Board stiffness is determined by the physical makeup of the substrate i.e. - its thickness, fibre mix, coating and manufacturing method. It is determined by measuring the resistance of a cut sample to a force applied through a pre-determined angle.

CBT1 Speed Action

Maximum Speed

To be most cost effective, it is important this conversion is performed at the maximum speed possible without causing mis-feed and blockages in the process.

Making a crease diagram

Crease resistance is a similar measure of resistance which is made across a preformed crease in the carton blank.

Features and applications

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

Automatic dwell time

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

Automatic stiffness and crease ratio

Results calculated and displayed instantly on screen.

Automatic statistical calculation

Full statistics are displayed for both crease recovery and board stiffness.

Test types

Making a Board Stiffness Test

Board stiffness is measured on a sample 70 mm x 38mm in size. Board stiffness differs slightly according to whether it is tested with the liner on the side touching the load bar, or on the other side.

CBT1 15 deg stiffness
15° Board Stiffness

The board direction required for test should run along the 70mm length of the specimen. A number of samples should be tested in each direction. It is recommended that you test MD and CD separately to get accurate results and a crease to board
stiffness ratio.

Sample Testing CBT1

Making a Crease Stiffness Test

The size of a standard BS6965 crease sample is 38x38mm with the crease line 13mm in from one edge. The CBT1 instrument is designed to test crease samples of the above size only.

CBT1 90 deg crease
90° Crease Recovery

The diagram illustrates MD and CD samples with creases across them, as will be required for crease stiffness testing.

Export to USB Stick

Measurements made using the CBT1 can be exported to a USB stick via interface software. The data can be transferred to the USB stick. All measured and calculated parameters are exported in .csv file format, as shown below:

Export to Results Printer

Using a custom data cable and pre-programmed label printer the results from the CBT1 instrument can be sent directly to a label printer.
