Edge Crush Tester

This tesing instruments designed to gauge cardboard's resistance to edge crush is called an edge crush tester. This machine tests the cardboard's strength and durability by applying a compressive force on it.

The edge crush tester has two firm plates that are used to push against the corrugated cardboard edges. Since the pressure in this tester raised gradually, the maximum force needed to hold the sample is determined. 

The edge crush test is very important for evaluating the performance of cardboard packaging. The test is significantly important because it determines the ability of the material inside cardboard to withstand pressure. It involves stacking, transportation or other forms of pressure. 

Edge crush tester is a beneficial testing instrument for a range of industries such as packaging, paper making, quality inspection etc. It is a great instrument for the determination of the probable compression strength of corrugated boxes. This is done by testing the paper board used in their manufacturing.

Edge crush tester is also known as Flat Crush tester or Ring Crush Twister. 

It tests the papers for corrugated boxes accurately. It can also be used for compression tests on small materials. Moreover, The rigidity of the CFB box is depicted by the higher ECT value determined by the ECT tester.

So, maybe the quality of the CFB board is compared to this.

In addition, by using Mckee’s formula, the compression strength of the box can also be determined.

The edge-wise compression strength of corrugated boxes is important to test for determining the power of materials inside the boxes. It is important to determine whether the material withstands shipping pressure or not. 

Effective Lab India is the best manufacturer and supplier of ECT. ECT is in demand nowadays because several industries test their corrugated boxes for safe shipping. The digital model of ECT manufactured by Effective Lab India is designed for a simple and accurate readout.

An edge crush tester is an equipment which is structured for measuring the edge crush resistance of cardboard. This machine subjects the cardboard to a compressive force and asses the durability and strength of the cardboard.

There are two rigid plates in the edge crush tester which are used for applying pressure to the edges of corrugated cardboard. In this tester, pressure increased gradually and hence the maximum force of withstanding the sample is measured.

1. Sample Preparation: A strip of corrugated board, usually 25mm wide, is cut from the material to be tested.
2. Testing Process: The sample is placed vertically between two compression platens.
3. Compression: The platens are brought together at a constant rate until the sample collapses.
4. Measurement: The maximum force the sample can withstand before collapsing is recorded. This force is typically measured in pounds per inch (lb/in) or kilonewtons per meter (kN/m).

1. Packaging Integrity: Ensures that packaging materials can protect their contents during transit and handling.
2. Quality Control: Helps manufacturers maintain consistent quality by regularly testing production samples.
3. Cost Efficiency: Aids in optimizing material use, balancing cost and strength to meet specific requirements without over-engineering.
4. Compliance: Ensures packaging meets industry standards and regulations.

• Corrugated Boxes: Commonly used for shipping and storing goods, these boxes require high edge crush strength to prevent deformation and protect contents.
• Paperboard Packaging: Used in consumer goods, food packaging, and pharmaceuticals, where product safety and shelf appeal are crucial.
• Point of Purchase Displays: Requires durability to withstand handling in retail environments.

1. Material Composition: The type and quality of paper used in the corrugated layers.
2. Flute Structure: The size and shape of the flutes (waves) between the liners affect the overall strength.
3. Adhesives: The quality of the glue used to bond the layers.
4. Environmental Conditions: Humidity and temperature can impact the strength of corrugated board.

Several standards guide the Edge Crush Testing process, ensuring consistency and reliability. Key standards include:

• TAPPI T 838: Technical Association of the Pulp and Paper Industry standard for measuring edge crush resistance.
• ISO 3037: International Organization for Standardization standard for determining edgewise crush resistance of corrugated fiberboard.
• ASTM D 7030: American Society for Testing and Materials standard for measuring the edge crush resistance of corrugated fiberboard using the clamp method.
