Significance Of Paper Board Stiffness & Crease Testing

The significance of the stiffness and crease factor is high when it comes to paper and board. Both of them play an important role during the end use and conversion. 

Paper with low grammage requires high stiffness during the conversion processes. On the other hand, paper like those of books and magazines requires low stiffness to achieve folding endurance and conformability. Plus, the stiffness also matters significantly for high grammage papers, for example, paperboards or carton boards. It is basically a useful mechanical property to comprehend the bulging and stacking strength of the board during the end purpose. Manufacturers make use of UEC’s user-friendly stiffness tester for paper to test the stiffness of both paperboard and paper.

In addition to the board stiffness, manufacturers also measure the crease stiffness of the board. The result of the evaluation helps them to understand the crease performance and also to compare the crease stiffness of different cardboard materials. A crease stiffness tester is used for this objective. 

Both the board stiffness and the crease stiffness help determine the optimum conversion and packaging pace. They also present the ultimate stability of the final product. The bending stiffness test requires a physical form of the substrate such as the manufacturing technique, coating, thickness, and fiber blend. It measures how much does a sample can withstand a force applied from a pre-decided angle. On the other hand, the crease resistance measures the parameter across a pre-build crease in a carton box. 

Both these instruments and even the Taber stiffness tester are cost-efficient equipment. Each instrument offers high accuracy and functionality, and are easy to be operated by individuals. 

Bottom Line

If you’re looking to source cost-efficient, high-performance, and accuracy-driven paper physical property testing machines it is time to associate with UEC.
