ECT is a measure of the edgewise compressive strength of corrugated board. It is measured by compressing a small segment of board on edge between two rigid platens or plates perpendicular to the direction of the flutes until a peak load is established.

ECT-48 boxes, which are also commonly referred to as 48 ECT boxes, are heavy-duty corrugated materials that boast high-strength double wall construction.

Below is a chart that breakdowns different types of corrugated material and their corresponding bursting test and ECT rating, along with the maximum load per carton. The 32 ECT, 44 ECT, and 48 ECT are the most common box varieties, due to …

The edge crush test (ECT) tests how much weight can be stacked on top of a box without the edges being damaged. Common ECT ratings are 32 for single-wall boxes, 44-48 for double-wall boxes and 60-90 for triple wall boxes.

2019年5月18日 · 很多人不知道 ect 边压怎么来的： 下面我们以 51ect b/c 为例： 51ect b/c 的意思是每 1 平方英寸的纸板要能承受 51 磅的压力。 而下表要求的边压强度为牛顿/米。

To ensure their quality and ability to withstand pressure, the Edge Crush Test (ECT) is used. The ECT measures the amount of force a corrugated box can withstand before it collapses. The ECT is an essential test for manufacturers and suppliers of corrugated boxes.

ECT确定的是纸板结构的装载性能，而耐戳穿强度测定的则是戳穿纸板所需要的强度。 压平纸板并不会对耐戳穿强度造成太大的影响，因为面纸的强度基本上是不变的。 不过，如果楞型遭到破坏，就会大大地影响ECT值。 同时，纸箱在堆码过程的抗压强度也会降低。 将近一个世纪以来，研究人员已经研究出各种关联，能可靠地估计出纸箱性能。 1963年McKee et al.出版的一篇文章已经成为这一领域中有着奠基意义的学术论文，其中包含了推算纸箱抗压强度的公式。 随后，人 …

275# DW / 48ECT B/C-flute is an example of accepted industry standard corrugated verbiage that defines comparable Board Grades. All boxes are ECT - Edge Crush Test unless stated otherwise.
