What does 48 ECT stand for?
What does 48 ECT stand for?
Edge Crush Test
ECT stands for Edge Crush Test and is one of the most popular methods of determining the actual strength of a corrugated box or other corrugated material. Ultimately, edge crush testing shows us two things: box compression strength and stacking strength.
What is ECT in corrugated box?
ECT is a measure of the edgewise compressive strength of corrugated board. It is measured by compressing a predefined section of board on its edge between two rigid platens. This compression is performed perpendicularly to the direction of the flutes until the board collapses and a peak load is reached.
What does 32 ECT mean for boxes?
stacking strength
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. Greater bursting strength means fewer crushed and damaged boxes during shipping.
How do you calculate the ECT of a corrugated box?
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. This is measured in pounds per lineal inch of load bearing edge (lb/in), but usually reported as an ECT value (for example, 44 ECT).
How much weight can be stacked on a 44 ECT box?
A 1,000 square feet of the cardboard used in 44 ECT single wall box could weigh 149 LBS….Edge Crush Test (ECT) or Bursting Strength Test (Mullen)
| Weight | Mullen # Per Square Inch | Edge Crush Test (ECT) |
|---|---|---|
| 65 Lbs. | 200# | 32 ECT (Most Common) |
| 80 Lbs. | 225# | 40 ECT |
| 90 Lbs. | 300# | 44 ECT |
| 120 Lbs. | 326# | 55 ECT |
Is a 44 ECT a double wall?
This type of box can be purchased in single or double wall to resist tearing, splitting, or bursting. All of our heavy duty boxes are 44 ECT and are approximately 35% stronger than standard boxes.
How much weight can be stacked on a 32 ECT box?
65 lbs.
In general, the single-walled 200# test box and the 32 ECT corrugated boxes are interchangeable – both have a maximum weight limit of 65 lbs. Because stacking strength has become the most important factor for most warehouses today, many opt for the 32 ECT.
How much weight can a 44 ECT boxes hold?
95 lbs
Which Rating Should I Use: Burst Test or ECT?
| MULLEN TEST VS. ECT RATINGS (SINGLE WALL) | ||
|---|---|---|
| Mullen Burst Test Rating | Minimum Edge Crush Test | Maximum Load Per Carton |
| 125# | 23 ECT | 20 lbs. |
| 200# | 32 ECT | 65 lbs. |
| 275# | 44 ECT | 95 lbs. |
How much weight can a corrugated box hold?
A standard panel of corrugated cardboard can hold 32 lbs. The burst test sees how much pressure (pounds per square inch) is needed to bust a hole in a panel. A typical piece of corrugated cardboard can hold 200 lbs.
Is B flute or C flute stronger?
Between 3.5mm and 4mm in thickness, C flute offers greater compression strength than B Flute. This means it provides better stacking strength when used for lightweight products.
How much weight can a 44 ECT box hold?
Which flute is best for corrugated box?
C-flute
C-flute is the most widely used flute size, commonly used for shipping cases. Often used for packaging glass products, dairy products, and furniture, C-flute offers good crushing resistance, good stacking strength, and highly acceptable printing properties.
What’s the ECT rating for a corrugated box?
If a corrugated container has a 55 ECT rating, it means that it can withstand a 55 lbs of pressure on the edges of the cardboard. Edge crush testing is generally the test you want to be done when testing your package strength for B2B shipping, especially if the packages are medium- to small-sized and going to be stacked on top of one another.
What’s the maximum load for a corrugated box?
Corrugated Boxes – Edge Crush Test (ECT) Bursting Test Minimum Edge Crush Test Maximum Load Per Carton Standard 200# 32 ECT 40 lbs. Heavy Duty 275# 44 ECT 65 lbs. Heavy Duty – Double Wall 275# 48 ECT 80 lbs.
What do you need to know about edge crush test for corrugated boxes?
Corrugated Boxes – Edge Crush Test (ECT) That is, the Burst Test requires that the base papers used to make corrugated fiberboard weigh at least a certain minimum number of pounds per given unit area. The ECT eliminated this requirement, which allows the use of lighter weight materials while still providing high performance.
What does 55 ECT mean on cardboard box?
Understanding the specifications of an ECT chart is relatively easy. If a corrugated container has a 55 ECT rating, it means that it can withstand a 55 lbs of pressure on the edges of the cardboard.
