A device called an Edge Crush Tester (ECT) is utilized to assess the edgewise compressive strength of corrugated boards, while also helping to determine stacking strength and durability. It evaluates how much stress the material can sustain before it bows, when you measure and apply so much stress on the edge of the corrugated material to determine maximum compressive strength. The test ensures that the packaging boxes that manufacturers produce have adequate strength that protect the contents from rough handling in storage and transit. In addition, the ECT value is useful in determining the handling capacity of the box, making it an essential tool for quality control in the packaging sector.
An Edge Crush Tester (ECT) is a high-quality testing device used to assess the edgewise compressive strength of corrugated boxes and boards. Testing with the ECT helps determine a material's resistance to crushing when pressure is applied vertically, a need-to-know measurement when assessing the stacking strength of packaging. Using the principles of compression, the tester applies force perpendicular to the edge of a sample of corrugated box board until the material crushes. The highest load sustained is the material's edge crush strength, assuring uniformity of the packaging’s use.
An Edge Crush Tester will exert a controlled compressive force on the edge of a corrugated board test specimen between two rigid plates. The test specimen is loaded perpendicular to the surface of loading to represent the actual conditions of stacking. With plates closing together, pressure is incrementally increased until the test specimen breaks. Next, the tester measures the greatest force when the sample fails, also known as the Edge Crush Test (ECT) value. ECT is a measure of the board's stacking strength and helps manufacturers design packaging that will be resilient to handling, storage, and transportation without damage.
Here are the benefits of the Edge Crush Tester explained in detail:
Guarantees Packaging Strength
The Edge Crush Tester evaluates the compressive durability of corrugated boxes to protect them from stacking loads through transport and storage. By verifying edgewise strength, manufacturers can ensure that all packaging materials are durable enough to prevent goods from crushing and deforming under excessive load.
Improves Quality Control
Manufacturers can ensure consistent product quality from the results of frequent edge crush tests. It allows them to recognize weak points in corrugated materials before manufacturing in mass quantities, ensuring only quality boards are used. This alone can help reduce loss of product, consumer returns, and loss of profits due to package failure.
Maximizes Material Use
The Edge Crush Tester maximizes raw material utilization by accurately measuring board strength requirements for specific applications. This enables manufacturers to find the most appropriate cost/performance balance, minimizing material waste, and still producing boxes with sufficient load-bearing ability for safe carrying and storage.
Enhances Customer Satisfaction
Better and more durable packaging guarantees that products arrive with customers in pristine condition. Through the application of an Edge Crush Tester, companies can create boxes with maximum strength, reducing the risk of damage during handling and shipping, thus enhancing brand image and customer satisfaction, and trust.
Here are the applications of the Edge Crush Tester, explained in detail:
Corrugated Box Production
When corrugated boxes are produced, one tests the edgewise board strength prior to conversion to boxes using an Edge Crush Tester. This guarantees that only material with adequate compressive strength is used, resulting in strong boxes capable of withstanding stacking and transportation forces.
Paper and Packaging Industry
The tester finds extensive application within the paper and packaging industry to analyze the performance of corrugated sheets and paperboards. It assists manufacturers in identifying the right materials for various packaging requirements, providing durability, cost-effectiveness, and adherence to quality standards.
Quality Assurance Laboratories
Edge Crush Testers are valuable pieces of equipment found in many quality control laboratories performing routine testing and control on packaging material. They help in identifying differences in material quality to ensure that every batch of corrugated board produced meets internal, industry and customer specifications before packaging production.
Transportation and Logistics
In logistics, the Edge Crush Tester helps design boxes that can withstand stacking loads and vibrations during transport. It helps boxes retain their structure during transport to avoid product damage and reduce financial losses due to crushed or deformed boxes.
