About paper MIT folding tester The folding resistance is the index of the folding fatigue strength of paper and paperboard. It is used to show the ability of paper and paperboard to resist the reciprocating folding and is an important index to measure the mechanical properties of paper and paperboard. All in the use of the need to often fold the paper, generally on its folding resistance requirements are more strict.For example, the carton carton requires a high folding resistance, otherwise [...]
