A corrugated box is constructed from durable, layered cardboard, designed to last and safeguard the items within. This box features a wavy middle layer that enhances strength and provides padding. Various types of this wavy layer exist; for instance, the thick A flute is ideal for heavy items, while the C flute is commonly used and performs well for shipping purposes. Triple-wall boxes, consisting of seven layers, can support very heavy loads, making them excellent for storing large quantities of goods. As online shopping continues to expand, corrugated packaging has become essential for ensuring products are shipped safely to destinations everywhere.

How are corrugated boxes made?
Materials used in corrugated boxes
Corrugated boxes are made with strong, reliable materials. The main material is paper pulp, which comes from recycled paper or new fibers. Kraft paper is often used because it is tough and hard to tear. Glue holds the layers together, and inks add designs or logos to the box.
Each year, 33.3 million tons of corrugated boxes are made. Out of this, 96.5% are recycled, showing they are eco-friendly and widely used.
Category | Amount (tons) | Percentage of Total Generation |
|---|---|---|
Corrugated boxes generated | 33.3 million | 11.4% |
Corrugated boxes recycled | 32.1 million | – |
Recycling rate for corrugated boxes | 96.5% | – |
The manufacturing process
Making corrugated boxes involves several steps to ensure quality. First, raw materials are checked to make sure they meet standards. Then, paper pulp is heated with steam to create the wavy fluted layer. This layer is glued between two flat cardboard sheets.
Next, designs are printed, and box shapes are cut out. Machines fold and glue the boxes into shape. Finally, the boxes are bundled and prepared for shipping. Each step ensures the boxes are strong and ready to use.
Manufacturing Stage | Description |
|---|---|
Raw Material Inspection | Checking the quality of materials used to make boxes. |
Process Control | Watching each step to keep quality high and meet standards. |
Finished Product Testing | Testing the strength and quality of the finished boxes. |
Printing and Die Cutting | Adding designs and cutting box shapes from printed sheets. |
Folding and Gluing | Folding and sealing the boxes with special machines. |
Bundling and Shipping | Packing boxes for safe delivery or storage. |
Importance of the fluted layer
The fluted layer is the most important part of a corrugated box. Its wavy shape cushions items and absorbs shocks during shipping. It also makes the box strong enough to stack and carry heavy loads.
Tests like the Edge Crush Test (ECT) and Mullen Burst Test show how strong the fluted layer is. For example, a 32 ECT rating works for light items, while a 44 ECT rating is better for heavy shipments. These tests help ensure boxes meet industry needs.
Test Name | Description | Example Ratings |
|---|---|---|
Edge Crush Test (ECT) | Tests how much vertical pressure the box can handle. | 32 ECT for light items (<30 lbs), 44 ECT for heavy items |
Mullen Burst Test | Tests how much force is needed to puncture the box. | 200# for regular boxes, 275#+ for heavy items |
Box Compression Test (BCT) | Tests how much weight a box can hold before breaking. | Important for stacking on pallets |
Specifications of corrugated boxes
Flute profiles and their types
Flute profiles are important for a corrugated box’s strength. These are the wavy layers between two flat cardboard sheets. Each type of flute has its own advantages:
E Flute: Very stiff and resists crushing. It stops surfaces from bending and is great for light packaging.
B Flute: Strong and crush-resistant. It works well as an inner layer.
C Flute: Often used for shipping boxes. It gives good strength and padding.
A Flute: The thickest flute. It absorbs shocks and stretches for heavy-duty use.
Flute Type | Flat Crush Resistance | Vertical Compression Strength | Parallel Compression Strength |
|---|---|---|---|
E | Very High | Very Low | Very High |
B | High | Low | High |
C | Medium | Medium | Medium |
A | Low | Very High | Low |
Board types (single-wall, double-wall, triple-wall)
The number of layers in a box decides its board type. Single-wall boxes have one fluted layer. They are light and affordable. In 2023, these boxes made $97.2 billion, growing by 5.3%. Double-wall boxes have two fluted layers. They are stronger and hold heavier items. Triple-wall boxes have three fluted layers. They are the strongest and used for industrial purposes.
Grades and strength classifications
Corrugated boxes go through tests to meet standards. The Bursting Strength Test checks how much pressure the walls can handle. The Edge Crush Test (ECT) measures how well boxes stack. Other tests check water resistance, puncture strength, and compression.
Standard/Specification | Description |
|---|---|
ASTM | Rules for corrugated boxes in different industries. |
TAPPI | Paper and board quality guidelines. |
ISTA | Tests for how packaging performs. |
Box Maker’s Certificate | Proves the box meets strength and quality rules. |
These tests help pick the right box. They ensure safety and durability during shipping.
Benefits of corrugated boxes
Durability and protection
Corrugated boxes are strong and protect items during shipping. Their special design has a wavy layer between two flat sheets. This gives great cushioning and absorbs impacts. It keeps products safe, even with rough handling or tough transport.
The Mullen Test checks how much pressure a box can take before breaking. For instance, a 200# box can handle 200 pounds per square inch.
The Edge Crush Test (ECT) measures how well a box resists crushing from vertical weight. A higher ECT score means the box can hold more weight without collapsing.
Corrugated boxes are more durable than other packaging materials. They are lightweight, making them easy to carry. Their strength protects fragile items like glass or electronics. Double-wall and triple-wall boxes are even stronger. They are perfect for heavy items like industrial tools.
