Paper Paper Fold Endurance Testing

Fold strength refers to the strength of a paper when repeatedly folded under a constant load. In other words, it is an indicator of how many times a paper can be folded until it breaks.

The folding strength is specified as the number of even layers, and the folding strength is log10 of the even layer number. Generally, it is a test parameter applied to wrapping papers. Determining the folding strength of a paper before and after aging is an important process.
