Edge Crush Tester – Reliable Compression Strength Testing by Pacorr
In the packaging industry, ensuring the durability and structural integrity of corrugated boxes is critical. Whether used for shipping, stacking, or storing products, the strength of corrugated packaging plays a vital role in protecting contents during transportation. One of the most important methods for determining the performance of such materials is the Edge Crush Test (ECT).
To meet this requirement with precision, Pacorr, a trusted name among manufacturers, suppliers, and exporters of testing equipment, offers the Edge Crush Tester – a powerful solution for evaluating the edgewise compressive strength of corrugated fiberboard.
What is an Edge Crush Tester?
An Edge Crush Tester is a lab-grade instrument designed to measure the edgewise compressive strength of corrugated cardboard and paperboard. This test determines how well a piece of corrugated board can resist crushing when pressure is applied perpendicular to its edge. The result, expressed in kilonewtons per meter (kN/m), indicates the board’s ability to withstand stacking and handling pressure.
This test is particularly important for packaging designers and manufacturers who want to ensure that their corrugated boxes won’t collapse or deform when stacked during warehousing or shipping.
Why is Edge Crush Testing Important?
The strength of a corrugated board is not just about thickness or weight—it’s about how it performs under load. Edge Crush Testing provides critical data that helps packaging professionals:
Predict Box Compression Strength (BCT)
Ensure safe stacking of cartons in warehouses and transit
Reduce packaging material cost without compromising strength
Maintain compliance with industry standards such as ASTM D641, TAPPI T-811, and ISO 3037
Avoid shipping damage, product loss, and customer dissatisfaction
For manufacturers, suppliers, and exporters, edge crush testing is essential in validating packaging performance and minimizing logistics-related risks.
Applications of Pacorr’s Edge Crush Tester
Pacorr’s Edge Crush Tester is used across industries that depend heavily on corrugated and paperboard packaging:
1. Corrugated Box Manufacturing
To test raw corrugated sheets, determine the crush strength of different flute types, and maintain consistency in production.
2. E-commerce and Shipping
To ensure boxes used for delivery can withstand handling, stacking, and long-distance transportation.
3. Food and Beverage
To check packaging strength for carrying bottled products, canned goods, and packed food items.
4. Pharmaceuticals
To validate packaging used for storing and distributing medical supplies and fragile items safely.
5. Electronics and Industrial Goods
To assess whether protective cartons used for sensitive electronics or hardware meet strength standards.
How the Edge Crush Test Works
The testing process using Pacorr’s Edge Crush Testing is simple but highly effective:
A sample of corrugated board is precisely cut to standard dimensions.
The sample is placed vertically between two compression plates.
A steadily increasing force is applied until the sample buckles or fails.
The peak force sustained by the sample is recorded as the Edge Crush Strength.
This test helps determine the maximum load the board can bear without collapsing—a key factor in calculating the overall strength of a corrugated box.
