The Edge Crush Test rates how much weight can be stacked vertically on a box without damage and the Mullen Test rates how much force it takes to puncture a wall of the box. ECT rating is important to consider when stacking boxes, while Mullen rating is important for sharp & irregularly shaped items. See below for recommended ratings.

The ECT or Edge Crush Test method is used to determine the quality of the moving boxes sold by Uboxes. The ECT is the most current testing procedure adopted by the industry replacing the older standard of Bursting Method also known as Mullen Method.

2021年4月19日 · 常用纸箱ect对应的边压和耐破强度表以及计算方法.docx,Prepared on 24 November 2020 Prepared on 24 November 2020 常用纸箱ECT对应的边压和耐破强度表以及计算方法 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

A newer standard that has achieved widespread acceptance is the Edge Crush Test (ECT). This is a true performance test and is directly related to the stacking strength of a carton. ECT is a measure of the edgewise compressive strength of corrugated board.

2022年3月31日 · 纸箱26ect是指纸箱边缘边压强度为26。 边压强度是一定宽度的试样，在单位长度上所能承受的压力，它是指承受平行于瓦楞方向压力的能力。 ECT被广泛地认为是纸箱的 抗压强度 和堆码强度*重要的影响因素。

2021年3月18日 · what exactly is an edge crush test (ect)? In its simplest terms, an ECT tells you exactly how much weight can be stacked on top of a corrugated sheet (or box) before the it is crushed. It’s measured by taking a corrugated sheet (a.k.a. the material that makes up a box) and applying weight to the edge of the sheet until it crushes.

Due to using less material, ECT boxes have two distinct advantages over Mullen Test boxes. They provide more sustainable benefits and reduce shipping costs through their lighter weight.

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。

2023年10月12日 · When comparing two identically sized boxes with equivalent strengths, one being Mullen Test rated and one being ECT rated, the ECT-rated box will weigh less because it uses less corrugated material. The Verdict—ECT Boxes Offer Equivalent Strength and a More Sustainable Choice

A newer standard that has achieved widespread acceptance is the Edge Crush Test (ECT). This is a true performance test and is directly related to the stacking strength of a carton. ECT is a measure of the edgewise compressive strength of corrugated board.
