What instrument is used to test the bond strength between layered paper layers

    Before putting the paper into production, it is necessary to measure the interlayer bonding strength of the laminated paper. Most manufacturers generally use an electronic peeling machine for measurement, but in order to guide the production conveniently and quickly, the interlayer bonding strength tester is used instead of the electronic peeling machine to measure the delamination. The bonding strength between layers of paper, the most critical physical index of layered paper is the bonding strength between layers, that is, the Z-direction bonding strength, which reflects the size of the tear resistance between the two layers of the paper, which not only saves costs, but also greatly Improved operating speed.


    The interlayer bonding strength tester is mainly used to test the Z-direction tensile strength of paper and cardboard (ie, the interlayer bonding strength). Reflects the ability of paper and cardboard to resist the separation between layers, that is, the internal bonding strength of paper and cardboard. It is widely used in printing, packaging and other industries.

Application scope:

Layered paper materials such as paper, cardboard, grayboard paper, and ox cards, cigarette cases, fiber materials, etc.
