Folding resistance is one of the basic mechanical properties of paper, which is used to indicate the ability of paper to resist reciprocating folding. The folding resistance of the paper is the number of folds required to measure the stretch of the paper after being stretched by a certain force and then folded back and forth until the paper breaks.It is expressed in number of times, the unit is double fold.According to the longitudinal cutting, the test result is the longitudinal folding resistance; according to the transverse cutting, the test result is the transverse folding resistance. Generally, the longitudinal folding resistance is higher than the transverse folding resistance, which is due to the arrangement of the fibers and the high bonding strength of longitudinal fibers.

Folding resistance is one of the important indicators of the mechanical strength of paper and paperboard. The folding resistance is very meaningful for reflecting the performance of the paper bag and the carton lining paper. Any paper that needs to be folded frequently when used generally has strict requirements on the folding resistance.

GESTER's MIT Folding Endurance Tester is used to determining the folding resistance of paper. MIT Type Paper Folding Endurance Tester GT-N16 conforms to the standards ISO 5626, GB/T 2679.5, QB/T 1049 and is apply to the measurement of paper and other sheet materials with thickness less than 1 mm.With data processing function, Folding Endurance Test For Paper can directly output statistical result data. easy to operate, easy to adjust, and  stable performance.
