SK Edge Crush tester – Digital (ECT) is rugged enough for any production testing environment. It is the ideal testing equipment for paper making, packaging, quality inspection department and more. ECT tester – Digital (ECT) is a useful equipment for determining the probable compression strength of corrugated and solid fiber board boxes by testing the paper and paper-board used in making such boxes.
Edge Crush Tester / Ring Crush Tester / Flat Crush Tester is used for accurate testing of paper, paper-board, solid fiber-board & corrugated board for ECT test and its components. The Edge Crush tester can also be used for performing compression test on all small packages.
The crushing resistance is determined in terms of KN / unit length. The value calculated by ECT tester will depend on glue (i.e. pasting substance) bonding.
The higher ECT value determined by the ECT tester depicts the rigidity of the CFB box. Hence, it may be used to compare the quality of the CFB board. It is also possible to determine the compression strength of the box (CFB) by using ECT tester with McKee’s formula i.e.Compression strength = k. ECT x T x ZWhere, K= Constant
ECT = edge crush test value
T=Thickness of CFB board (wall thickness)
Z= Perimeter of the box i.e. (2 L + 2 W)
