Edge Crush Tester – Ensuring Corrugated Box Strength and Durability

 

Introduction

Packaging is more than just a covering—it’s the first shield that protects a product during stacking, handling, shipping, and storage. For industries that depend heavily on corrugated boxes, packaging failure can lead to costly losses and dissatisfied customers. That’s why Edge Crush Testing (ECT) has become an essential quality control step for packaging manufacturers worldwide.

At Pacorr Testing Instruments, we manufacture high-precision Edge Crush Testers designed to evaluate the edgewise compressive strength of corrugated fiberboards. Our machines help industries maintain consistency, cut costs, and ensure compliance with international standards.

What is an Edge Crush Tester?

An Edge Crush Tester is a laboratory testing instrument that measures the load-bearing capacity of corrugated boards when force is applied on their edges. This value directly relates to the box compression strength (BCT), which determines whether cartons will hold up under vertical stacking pressure.

A higher edge crush value means:

  • Stronger corrugated board

  • Better stacking performance

  • Improved product protection during supply chain movement

Why Edge Crush Testing is Critical?

  1. Product Safety – Ensures goods remain intact during storage and transport.

  2. Cost Optimization – Helps select the right paper GSM and flute combination without overdesign.

  3. Quality Assurance – Guarantees consistency in packaging across production batches.

  4. Sustainability – Supports lightweight packaging without compromising strength.

  5. Compliance – Meets standards such as TAPPI T811, ISO 3037, and ASTM D7030.

Understanding Salt Spray Chamber Why Corrosion Testing Matters for Quality and Durability

Image
  Salt spray chambers, also known as salt fog chambers, are essential tools in industrial and material science applications for assessing the durability of materials in corrosive environments. As corrosion remains a primary concern for many industries—from automotive to aerospace and electronics—salt spray testing provides a controlled, accelerated environment that reveals how materials or coatings react over time to salt exposure. This article explores the importance, applications, and benefits of salt spray chambers in ensuring product durability and reliability. 1. What is a Salt Spray Chamber? A salt spray chamber is a laboratory device designed to simulate a harsh, salt-laden environment. The Salt Spray Chamber creates a fine, consistent mist of salt solution, typically a mixture of water and sodium chloride, which settles on the test materials. This controlled environment can replicate years of natural exposure in a fraction of the time, providing essential insights int...
