What Are the Different Corrugated Packaging Flute Types?

In the world of packaging, choosing the right materials can make all the difference in protecting and presenting your products. As a business owner, you may have encountered the term “corrugated” in reference to boxes, but do you know the different corrugated packaging flute types and how to choose the right one? We’ll explain the various flute types and offer guidance on selecting the most suitable option for your needs.

A Brief Overview of Corrugated Packaging

Before diving into the different flute types, it’s important to understand the basics of corrugated packaging. Corrugated boxes are constructed from three layers: an outer liner, an inner liner, and a fluted layer in between, which gives each box its unique structure capable of supporting and protecting various products.

The Different Flute Types

The flute is the wavy layer sandwiched between the outer and inner liners of corrugated boxes. There are various flute types, each with their own characteristics and benefits.


With approximately 33 flutes per linear foot, the A-flute offers excellent cushioning, making it ideal for fragile items.


Boasting around 47 flutes per linear foot, this option enhances crush resistance and is commonly used for retail-ready packaging and corrugated box printing.


With about 39 flutes per linear foot, the C-flute strikes a balance between A and B, offering solid stacking strength, cushioning, and printing capabilities.


With roughly 90 flutes per linear foot, the E-flute provides excellent crush resistance and a smooth surface for high-quality printing. This makes it suitable for e-commerce packaging, retail displays, and cosmetics packaging.


Offering the highest flute count—around 128 flutes per linear foot—the F-flute delivers optimal printing surfaces and is often utilized for luxury packaging or lightweight materials.

The Right Flute Type for Your Packaging Needs

When selecting the appropriate corrugated packaging flute type, there are a few key factors to consider, such as product weight, fragility, and printing requirements. Here are some essential aspects to keep in mind:

  • For heavy items that require additional support, consider using A-flutes or C-flutes.
  • For fragile items needing cushioning, an A-flute is the ideal choice.
  • In retail settings where print quality and crush resistance are crucial, B-flute or E-flute packaging can suffice.
  • For luxury or high-end packaging with detailed print, F-flute is an excellent option.

Understanding the different corrugated packaging flute types is vital for business owners looking to effectively present and protect their products. By evaluating factors like product fragility, weight, and printing requirements, you can confidently select the best flute type to satisfy both your brand image and product safety needs. Embrace the power of corrugated packaging to showcase your products and make a lasting impression on your customers.
