How much weight can be stacked on a 32 ECT box?
65 lbs.
Corrugated cardboard boxes are often piled up in a storage for a long time. In this video, the stacking strength of the corrugated cardboard is measured by a dual-column motorized test machine which can keep pressing the test sample for up to 999 hours and 59 mins with a maximum force of 5000N.
How strong is corrugated cardboard?
Corrugated boxes are very strong, but the answer to this question is going to depend on the size and type of box that you're using. A single wall box can hold between 20 – 120 lbs, double-wall boxes can hold 80 – 180 lbs, while triple wall corrugated boxes can hold between 245 – 300 lbs.19-Jun-2020
Box Strength
What is the difference between 200 lb test boxes and 32 ECT boxes?
200 lb. test refers to bursting strength, while 32 ECT refers to stacking strength. Boxes that meet 200 lb. test will also exceed 32 ECT stacking strength.
ECT is used as a way of telling you how heavy duty your box is. As an example, 32 ECT is similar to a standard box strength. 44 ECT is a heavy duty box strength. 48 ECT is a heavy duty double wall box strength.19-Sept-2019
What does 275 lb test mean?
For example, a single-wall corrugated cardboard box with a 275# Mullen Test rating must contain at least 175 pounds of base paper per 1,000 square feet of corrugated material.
Bursting strength is reported in pounds (for example, 275#). 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.
Why Cobb test is important for packaging?
The Cobb test is essential as it tests the ability of the paper to resist the penetration of water and quantity of water absorbed by the surface of fiberboard. If fiberboard absorbs too much water, the box may have difficulty maintaining strength and integrity.
Traditional cardboard is a thicker, heavier version of paper stock or pulp. For example, a cereal box is made from cardboard. Corrugated, on the other hand, might be made with cardboard materials, but the overall design and structure is much more durable.16-Feb-2020
What is thick cardboard called?
Carton Board – Carton Board is stiffer and thicker than boxboard. It has a medium to high compression and moisture resistance. Unlike cardboard, it is solid, and not fluted. Chop edge (or just chops) – the length of the board / sheet.18-Feb-2022
Chromo board is a thin board, coated on one or both sides and is white. It is often used in retail (i.e., inside men's shirts, under collars and in hosiery packaging).
What is the strongest corrugated cardboard?
One of the strongest types of corrugated we offer is called 275 Mullen BC. Let's quickly break down that name and what it means: BC means that this is a double-wall corrugated, stacking B-flute and C-flute on top of each other.30-Oct-2014
ECT is often looked at by customers who are concerned about the max weight a box can stand during pallet shipments or warehouse stacking. The most common and universal boxes used today are 32 ECT. The Mullen Test measures the bursting strength or the force required to burst a hole through the corrugated material.11-Mar-2021
How do you increase bursting strength of corrugated box?
The number of plies can be added in a corrugated sheet to enhance the strength of the boxes. Hence, we can conclude that one can easily increase bursting strength by increasing the number of plies of a fluted paper to enhance the strength of the corrugated boxes.
The next strongest box is 51 ECT or 350# Mullen double-wall, using a stronger liner board to hold up to 120 pounds.19-May-2022

What is 32 ECT corrugated?
The higher the number, the stronger the corrugated box. The Edge Crush Test, which was developed in the 1990's, measures the stacking strength of corrugated board – how much top to bottom pressure a box can withstand before crushing. Boxes conforming to the Edge Crush Test standard are identified as 32ECT, 44 ECT, etc.07-Oct-2008
What's a Box Maker's Certificate? It's a seal printed on the bottom of a box that tells you how strong it is. It's not legally required, but it's proof that the box has been properly tested and rated.05-Sept-2017
What is Mullen burst test?
The Mullen Burst Test uses a pressurized diaphragm to measure how much pressure (in pounds per square inch) the side of a corrugated box can take before it breaks. And analogy to this would be: how hard do you have to punch the side of a box to break through it.06-Jan-2020
