What does ECT stand for in cardboard?
What does ECT stand for in cardboard?
The Edge Crush Test (ECT) The Edge Crush Test, or ECT, is a newer test developed to look specifically at how much force a corrugated material can withstand on its edges without crushing. Instead of applying force to the face of the corrugated material, as the Mullen Burst Test does, ECT applies force to the edge.
How is cardboard rated?
Most corrugated cardboard boxes are rated using one of two tests: the Mullen Test (also called the Burst Test) or the Edge Crush Test. Although there are equivalencies built into the systems, you’ll usually find a cardboard box rated as one or the other.
What is 32 ECT corrugated?
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 is ECT measured?
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.
How is ECT calculated?
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 do you measure cardboard strength?
The Mullen Test or Bursting Strength Test checks the toughness of the walls of the corrugated board when subjected to force or pressure. In this testing procedure, a rubber diaphragm is used to apply pressure to the walls of the corrugated box until it bursts.
How do you test cardboard?
Corrugated Box Testing Methods:
- Bursting Strength Test.
- Edge Crush Test 2 Single.
- Water Resistance of the Gluing.
- Cobb Sizing Tester.
- Paper Grammage and Thickness.
- Puncture Resistance.
- Scuff Resistance Test.
- Box Compression Test.
What GSM is cardboard?
The higher number of GSM means heavier cardboard material. Although you will find packaging cardboard starting from 200GSM but My Box Printing offers cardboard boxes ranging from 250GSM to 1000GSM to ensure the higher quality packaging boxes to fulfil all of your packaging needs.
What ECT 44?
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.
How do you calculate the ECT of a 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). 40 lbs.
What is the difference between 44 ECT and ECT boards?
On average, the 275# Burst Test rated single wall carton will weigh 175 pounds per 1000 square feet of material used. An equivalent 44 ECT rated single wall carton will weigh on average 149 pounds per 1000 square feet of material used. The 44 ECT board will reduce the material used by 14.8%.
What is an ECT value?
The ECT or Edge Crush Test is a laboratory test that compresses a small piece of board edgewise between two plates until a peak force is reached. This is measured in pounds per inch (lb/in), but usually shown as an ECT value, for example 32 ECT.
Why do corrugated boards have different ECT values?
This is because corrugators may use one of many different “recipes” to make each type of corrugated. Each makeup will vary slightly in overall strength. For example differing formulas for a 200# single wall corrugated will cause the equivalent ECT board to vary between 32 ECT and 44 ECT.
What is the weight of a 275 ECT single wall Carton?
For example compare a 275# single wall to an equivalent 44 ECT single wall corrugated board. On average, the 275# Burst Test rated single wall carton will weigh 175 pounds per 1000 square feet of material used. An equivalent 44 ECT rated single wall carton will weigh on average 149 pounds per 1000 square feet of material used.
