The corrugated box is a staple in the shipping industry, offering a reliable and cost-effective way to protect products during transit. But if you want to ensure your product's safety, it’s essential to understand corrugated box strength guidelines.
Knowing corrugated box makeup and related strength statistics can help you make sure that whatever you ship arrives safely at its destination for the best possible price.
By understanding the structure of corrugated boxes, you can better evaluate their suitability for different types of shipments based on how cost-effective the box strength is. Some products don’t warrant that additional investment in the stronger corrugated box.
You know shipping materials must be sturdy and reliable, but what are the nitty-gritty details that separate the weak from the strong?
Not all paper used to make corrugated boxes is created equal. Specific paper qualities will depend on where the paper comes from and if any special additives have been used. For example, paper that originated in Taiwan may perform differently when used to make boxes than a paper with a similar weight and thickness from the United States.
Nearly all paper used to manufacture boxes contains recycled content. This is sustainable and helps keep costs low without sacrificing box performance. Although the boxes may vary slightly in color because of the variance in trees used, all paper used in North American box manufacturing has similar qualities and contains a similar amount of recycled content.
In certain cases, paper is coated or has artificial compounds added for additional strength and waterproofing qualities. These papers are ultra-specific, often only created in a vertical supply chain when the company designing the products is directing the exact makeup of their packaging material.

The thicker the paper, the stronger and more durable of a box it makes for carrying heavy loads.
Consider the following corrugated strength chart for guidance on the best combination of liner and corrugated medium:
Thinner papers, on the other hand, are better suited for transporting lightweight items. To ensure your product reaches its destination safely, choose a box with suitable paper thickness based on what you're shipping.
Fluting refers to the corrugated box's fluted or wavy layer within the box walls, which provides extra support and protection for whatever you’re shipping. Different types of boxes can have different types of fluting depending on the intended purpose, with some providing more cushioning and others offering increased structural stability.
There are 5 common flute types:
F-flute, which is rarely used. This type is very thin, good for print registration but does not provide a lot of protection.
E-flute, ideal for lighter loads because it has more corrugations per linear foot. The e-flue has a thin profile with many small flutes, which helps print quality.
C-flute, provides more cushioning than E or F-flutes. C-flute was developed as an all-purpose flute and is almost always used for regular slotted containers.
A-flute, also has lower corrugation counts and provides more thickness and cushioning. This type has 33 flutes per foot.

Damage to goods can cause not only monetary losses but also reputational damage to a business. While its important to choose sufficient protection, it is optimal to pick the most cost-effective board grade.
Consider the following factors:
All U.S. boxes are held to an official strength standard. There are two tests to determine box strength:
NOTE: With both tests, a higher number indicates greater strength.
There are many box styles, not to mention sub-varieties within each type of corrugated box design. The intended use and product presentation play a big part in choosing the right style. For instance, consider these three popular styles:
Choosing the right flute size means appropriate box strength and thickness, as well as improving structural stability and providing a better substrate to enhance applied prints.
Box manufacturing does not depend on the economy, the flutes are flutes, papers are papers, and board grades are board grades no matter what.
Using corrugated boxes with the correct strength and structure is one of the best ways to ensure that products arrive at their destination safely. Knowing corrugated box strength guidelines and understanding the structure of corrugated boxes can help you determine which type and combination is most suitable for your product.
By understanding corrugated box makeup and related strength statistics, you can determine the best box flute size.
Corrugated boxes offer a reliable and cost-effective way to protect products during transit. Knowing corrugated box strength guidelines means that your product will surely make it to where it needs to go in top condition.
This can not only reduce product damage or loss, but also save your business money in the long run.
By reducing cases of product damage, sellers can ensure their customers are satisfied and keep returning for business – but not returning their boxes.
Being proactive today means reduced return totals tomorrow.
