Paper and cardboard folding resistance tester

Product introduction of flexural strength tester：

The paper and cardboard folding resistance tester is a testing device used to determine the flexural fatigue strength of paper, cardboard, and other sheet materials (such as plastic film and metal foil) under standard tension. It characterizes the material's flexural performance by reciprocating 135 ° double folding times or corresponding numerical values. It is an essential tool for quality control and research and development innovation in the fields of paper making, packaging, quality inspection, and scientific research.

Test Principle：

Folding resistance refers to the number of double folds that paper or cardboard can withstand up to 135 degrees of reciprocating movement under a certain tension. It is expressed as the number of reciprocating folds or the logarithm of double folds with a base of 10. The number of times it is broken is recorded as the folding resistance.

Test Standard：

GB/T457、QB2679.5、ISO 5626
