7. Independent ventilation cooling system, suitable for long-term fatigue test of internal heat generated
8. Can be connected to a computer to automatically draw real-time test data Linear dispersion diagram (optional)
Principle
The test principle of paper folding resistance refers to the number of double folds that paper or Cardboard can withstand reciprocating 135 degrees under a certain tension, expressed by the number of reciprocating folds or by the number of double folds at the base of 10, and the number of times used to record breaking is the folding resistance.
