Testing of Paper Compound Materials

3-Point Bending Test

Possible applications for this method are tests on cardboard, paper based compounds or cores.

Internal Bond Test (Z-Direction Tensile Test)

For multi-layered materials (duplex paper, coated paper), the internal bond strength of the layers to one another is an important characteristic. It determines the further processability.

Coefficient of Friction

For the determination of the coefficient of friction, an important factor is the material of the two surfaces to be measured, „paper against paper", or „paper against other materials".

Tear Propagation Test

These characteristics are important for finding and avoiding weak spots in packaging with folded edges or bonded seams.
