Folding Endurance Tester for Paper and Paperboard’s Folding Endurance Test

Wewon Environmental Chambers Co., Ltd. specializes in the production of paper’s packaging testing instruments such as schopper folding endurance tester. The schopper folding endurance tester is used for determining the folding endurance strength of paper and paperboard. It is suitable for carton box board, kraft paper, corrugated paper, grey board and other materials with folding resistance test. Wewon’s MIT folding endurance tester will comply with the test standards such as : ISO 5626, TAPPI T423PM, ASTM D2176, JIS P8115, GB/T 2679.5 GB/T457.

Paper folding endurance tester from Wewon Tech using photoelectric control technology can make the folding chuck in each experiment after automatic return to the position, to facilitate the next operation. The machine has powerful data processing function: it can calculate the experimental data of multiple samples in the same group, and it can calculate the maximum, minimum, average value and coefficient of variation of samples in the same group. The data is stored in a microcomputer and can be displayed through a digital LED display device.

Test Methods for Schopper Folding Endurance Tester: The MIT flexural strength testing machine specifically detects the flexural strength of paper and cardboard. The test method is to fix the two ends of the sample on the machine, and apply the required load to the lower clamp to make the tested sample bear a certain tension. The lower clamp bends the tested sample back and forth to the left and right sides when the sample is vertical, the bending angle is 135 degrees until the sample is broken.
