PN-CT50KC Box Compression Strength Tester is designed to determine the compressive forces which a packaging container is subjected to, during transportation or carry and stacked. It is used for testing the whole box anti-pressure and stacking pressure and it is mainly suitable for corrugated boxes and other material packages size 1500*1500*1500 mm which anti-pressure is less than 50KN. Boxes can be tested to complete collapse or held automatically at a predetermined load for given period to evaluate stacking loads.
