Testing and Quality
Edge Crush Test
The Edge Crush Test (ECT) stands as a key measure of a corrugated box’s strength. This test evaluates how much compressive force the edge of a piece of corrugated board can withstand before it collapses. Manufacturers use ECT results to determine stacking strength, which is critical for boxes that will be piled on pallets or stored in warehouses. The ECT value, expressed in pounds per inch (for example, 32 ECT), tells users how much weight the box can handle along its edge.
Industry organizations such as the Fiber Box Association (FBA) and the Technical Association of the Pulp and Paper Industry (TAPPI) oversee these tests. Regular ECT testing ensures that boxes meet published acceptance criteria and comply with legal standards. The Box Maker’s Certificate (BMC) printed on each box includes the ECT rating, manufacturer details, and other key information. This certificate acts as a legally binding mark, confirming that the box meets minimum strength requirements set by Rule 41. Manufacturers must pass periodic audits to maintain compliance, which helps guarantee ongoing product reliability.
Tip: ECT-rated boxes are ideal for stacking and shipping applications where vertical compression is a concern.
Burst Test
The Burst Test, also known as the Mullen Test, measures a box’s resistance to external pressure and puncture. During this test, technicians apply increasing pressure to the surface of the corrugated board until it bursts. The result, given in pounds per square inch (psi), indicates how much force the box can withstand before failing.
This test is especially important for boxes used in shipping environments where impacts and rough handling are common. The Burst Test helps ensure that boxes protect their contents from sudden shocks or sharp objects. The BMC on each box will state whether the box passed the Mullen Test or the ECT, along with the minimum combined weight of facings and the maximum gross weight capacity. Adherence to these standards supports product safety and legal compliance, especially for export shipments.
Manufacturers monitor raw materials for paper quality and bonding to maintain high burst strength. Quality assurance teams perform regular burst testing as part of their continuous improvement programs.
Flat Crush Test
The Flat Crush Test (FCT) assesses the strength of the fluted medium inside the corrugated board. In this test, technicians apply pressure to the board’s surface until the flutes collapse. The FCT result shows how well the fluting can resist crushing forces, which is vital for protecting products from compression during stacking or transit.
Manufacturers use FCT results to validate the durability of their corrugated material. Continuous monitoring of board thickness, moisture content, and bonding ensures consistent quality. Dedicated quality assurance departments oversee these tests and inspections, making sure each batch of boxes meets strict industry standards.
Regular testing includes:
Ring Crush testing for paper strength
Compression testing for stacking resistance
Drop testing for safety-critical uses, such as UN-certified boxes
Quality inspections based on these tests help companies deliver reliable packaging that meets customer expectations and regulatory requirements. The combination of ECT, Burst, and Flat Crush Tests provides a comprehensive view of a box’s performance in real-world conditions.
Certifications
Certifications play a crucial role in the corrugated box industry. They help manufacturers, distributors, and customers verify that packaging meets strict quality, safety, and environmental standards. These certifications provide assurance that boxes perform as expected during shipping, storage, and handling.

Corrugated Boxes vs Other Packaging
Cardboard
Corrugated boxes and standard cardboard boxes differ in structure and performance. Corrugated boxes use a fluted layer between two liners, which gives them strength and cushioning. Cardboard, often called paperboard, consists of a single thick layer. This makes cardboard suitable for lightweight packaging, such as cereal boxes or folders. However, it does not provide the same level of protection as corrugated packaging.
Corrugated boxes support heavier loads and resist crushing. They protect fragile items during shipping and stacking. Businesses choose corrugated boxes for shipping electronics, glassware, and industrial parts. Cardboard works best for retail packaging where strength is less important.
Corrugated packaging also offers more customization options for branding and product fit. Companies can print high-quality graphics on the surface, helping products stand out on shelves.
Plastic
Plastic packaging appears in many industries due to its durability and moisture resistance. However, several factors make corrugated boxes a preferred choice for many businesses:
Plastic containers require a higher initial investment for purchase, maintenance, and replacement.
Regular cleaning and sanitization add to operational costs for plastic packaging.
Many types of plastic are not accepted by standard recycling facilities, limiting recycling options.
Plastic packaging has a low recovery rate of about 9%, and this rate continues to decline.
Corrugated boxes have a recovery rate near 90% over the past seven years, making them the most recycled packaging material in the United States.
Corrugated boxes are biodegradable and reduce landfill waste compared to plastic.
Corrugated packaging supports a circular economy by minimizing raw material use and energy consumption.
The average corrugated box is recycled seven times and contains nearly 52% recycled material.
Corrugated boxes also offer cost advantages. They have lower initial costs and do not require expensive maintenance. Their high recyclability and renewable material content help companies meet sustainability goals.
Companies seeking to reduce their environmental impact often choose corrugated packaging over plastic.
Wood
Wooden packaging, such as crates and pallets, provides strong protection for heavy or bulky goods. Many industries use wood for transporting machinery, produce, or export shipments. Wood offers excellent durability and can be reused multiple times.
A Life Cycle Assessment (LCA) study compared wooden packaging and corrugated cardboard for transporting 1,000 tons of mandarins over 2,000 kilometers. The study found that wooden packaging produced lower greenhouse gas emissions and had a smaller water footprint than corrugated cardboard. Wood also caused less eutrophication of fresh and marine water and had a lower impact on land acidification.
Packaging Type | Greenhouse Gas Emissions | Water Footprint | Eutrophication | Land Acidification |
|---|---|---|---|---|
Wooden Packaging | Lower | Smaller | Less | Lower |
Corrugated Cardboard | Higher | Larger | More | Higher |
Corrugated boxes remain lighter and easier to customize than wood. They also offer better printability for branding. For many products, corrugated packaging provides a balance between protection, cost, and sustainability.
