Developed by Messmer Büchel, our specialist physical properties inspection company, our crease and board stiffness tester measures crease line, bending resistance and spring back.
This industry-leading paper stiffness tester is ideal for paper, paperboard, plastic film, medical tubing and wire testing.
Crease and board stiffness testing is important if you make or work with corrugated, carton board, paper, printing and packaging products.
The relationship between board stiffness and crease recovery (spring back) affects the performance of cartons on high speed packaging machines and during manual folding. It’s essential that any creases in your boards are correct and uniform to avoid distorted packaging or harmful closure stresses.
The 79-15 gives you complete control when measuring the bending stiffness of paper and paperboard. It inspects the stiffness of your samples at 50mm and 15 degrees and the crease line at 10mm and 90 degrees.
For your convenience, our paper stiffness tester clamps are interchangeable. You can opt for our standard square clamps, while Philip Morris approved round-cornered clamps are available too.
A spring loaded clamp secures the sample. The clamp is manually rotated towards the fixed position. During a test, the continuous force value is displayed – after 15 seconds the maximum force is displayed.
Our crease and board stiffness tester comes with a sharp and reliable cutter so you can cut your test samples fast and with confidence.
Our crease and board stiffness tester only has one button. Just zero the test before you start each inspection…board stiffness testing doesn’t get much simpler than that!
We make a range of devices and accessories to measure the bending stiffness of paper and paperboard. Check out our Bending Resistance Tester 79-56 for example and get in touch if you have something else in mind.
We like to share the knowledge we have amassed over the decades at Industrial Physics. Why not visit our blog on testing the physical and optical properties of paper, or this piece on flexible packaging equipment and methods?
