The production process of cartons will also affect the compressive strength. According to the test, under the same conditions, the compressive strength of the carton decreases by 90n ~ 130n and the deformation of the carton increases by about 2mm for every 1mm widening of the transverse pressure line of the carton. Pressing line too wide, will cause the carton in the compression test force increase slowly, effective value is small, large deformation. In order to...
