flexural stiffness of corrugated board 1. scope this method is used to measure the bending resistance of corrugated fiberboard in the machine or cross machine direction with a bench-type instrument. 2. summary 2.1 this method measures the flexural stiffness of corr ugated board
the tester then continues further until the corrugated board collapses and the software automatically calculates the edge crush resistance value in the desired unit of measurement (lb/in, n/mm). bench-top models of ect compression testers are available in capacities of 2.5kn - 10kn depending on the range of board to be tested.
4.1.1 the corrugated fibreboard used shall not crack or delaminate on bending or creasing. the outer liner shall be hard sized and shall have good printability. the liners shall be firmly glued to the fluting. 4.1.2 the corrugated fibreboard shall be machine glazed (mg) or machine
easy way to analyze moisture content of corrugated boxes. during production of corrugated boards, manufacturers often face a unique problem caused by inaccurate control of moisture; if the moisture content of the corrugated box is higher, it may leads to collapsing of the box. on the contrary, a lower (than requisite) moisture contentmay lead to board breaking.
the controlling critical component of corrugated board is the medium under compression. pommier and poustis  studied the bending stiffnesses of corrugated board structures using models based on the finite element method and a developed linear elastic analysis code referred to as systus. the corrugating medium defined in the calculation code
