custom printed corrugated boxes   damaged. cardboard box with the ultimate compressive strength into rms value. Changes compressive strength value of the test is sometimes directly from slow to fast to the point of collapse, and some smooth sliding scale to the point of collapse. In the long compression tests, we found that the change may have a force value of the buffer: the amount of deformation when the force value to a certain extent, the deformation of the stopping force values ​​continue to increase, after a period of time, the value of the force to continue increase until the collapse point cardboard box. We can force the value of the buffer before the value known to have the effect, the amount of deformation is called the effective buffer before deformation. Buffer later, although the value can continue to increase the force, but the cardboard box has started to deform, can not achieve the requirements, so determining the compressive strength cardboard box quality standards should be a potency value compression testing. Two, cardboard box is constituted by the
