Food series yellow leather packaging box The carton used for transportation packaging inevitably has to undergo many handling, loading and unloading operations during transportation, and must have reasonable strength to protect the contents of the carton. When measuring the compressive strength of cartons, the effective perimeter and height are different with different placement methods, and their compressive strength is also different. In the whole pressure bearing process of the carton, four corners are mainly stressed, accounting for about two-thirds of the total force. The corner of the carton bears high pressure. The farther away from the corner, the lower the pressure. The distribution of compressive strength
1. Measure the external dimension of the transport carton
Weigh the package and its contents respectively, fill the package, and measure its external dimensions, i.e. the length, width and height of the carton.
2. Place the sample
Place the test sample in the center of the lower platen of the whole box of compression testing machine according to the preset state.
3. Select the working mode
Select one of the three operating modes.
4. Instrument parameter setting
Set the test speed (10mm/min), pressing plate spacing, crushing ratio, initial load and sample specifications of the instrument (length, width and height of the carton sample).
