Flute is common to describe the properties and structure of material being used in the packaging, especially corrugated cardboard boxes. A packaging flute plays an important role in the environmental impact, durability, and performance of the packaging. It is important to understand the types and importance of packaging materials like corrugated fiberboard.
What is a Flute in Packaging?
Flute definition refers to a corrugated layer in the center of the cardboard packaging, usually blended between two uniform sheets of a liner board. The flute offers structural support, enhancing the cushioning, rigidity, and strength of product packaging. This durable and lightweight solution safeguards packed products, ensuring the ideal arrival at the destination without damage.
The fluted layer is a hallmark feature that differentiates plain cardboard from corrugated cardboard. The material, shape, and size of the flute impact the physical characteristics and performance of the packaging.
What is Corrugation?
The corrugating definition refers to the reinforcing of cardboard being utilized in the product packaging. It resembles the wavy lines that are glued to a paperboard, creating a corrugated board. Therefore, fluting ensures that packaging withstands different crushing conditions.
What is a corrugated box? A corrugated packaging is a durable and solid shipping container created using multiple paperboard layers featuring air-filled grooves to ensure ideal space between these layers.
Fluting Styles for Packaging
Cardboard flute sizes are defined based on the paper thickness.
- Single-walled flutes are smaller flutes offering ideal foldability and printability.
- Double-walled flutes are larger flutes offering excellent cushioning and strength, which is ideal for shipping purposes.
Different Types of Flutes in Product Packaging
Flute types are based on different thicknesses and sizes. The common types are mentioned below:
- A-Flute: A type of flute with a thickness of up to 5/32 inches or 4mm, offering ideal cushioning to fragile products.
- B-Flute: B flute is thinner than A flute, providing a balance between cushioning and strength. Thickness is 3/16 inches or 4.8mm, which is the ideal flute sheet for packing electronics, food, and consumer goods.
- C-Flute: It is the most common flute type, ensuring excellent strength and cushioning. C flute thickness is 9/32 inches or 7mm, perfect for heavy-duty boxes for shipping products.
- E-Flute: E flutes are thinner than A, B, and C flutes. Moreover, the flute thickness is 1/16 or 1.6mm, ideal for retail-ready boxes, ensuring a fabulous visual appearance. E flute vs B flute can be used to pack smaller products.
- F-Flute: One of the thinner kinds of flute with a thickness of 1/32 inches or 0.8mm. A durable and lightweight option for retail packaging.
- N-Flute: The thinner and smaller flutes are lightweight and sleek options to enhance the presentation without prioritizing strength.
Each type offers different flute uses depending on their thicknesses. You can choose a flute to ensure stacking strength and visual appeal for products, improving customer experience.

Flute Thickness for Custom Packaging Boxes
The flute at the edges is usually visible and compressed. During the production, the boxes go through compression before the die cutting to ensure a compressed touch. You can measure the corrugated flute thickness by considering the flute in the center of the box due to no compression at that point. This thickness can vary at the packaging box edges.
The custom mailer boxes are cut at the edges using a sampling machine without causing compression. This means that the samples appear to be ‘taller’ due to uncompression. You must remember that edges experience more compression in bulk production.
Why Is Flute Matter Important in Packaging?
The flute in corrugated fiberboard offers many benefits to businesses seeking to improve the packaging experience.
Cushioning and Protection
The fundamental purpose of a flute in packaging is to safeguard packaged products. The wave-like structure of flutes, like the thickness of E Flute, absorbs shock while cushioning fragile or delicate items from vibration, impact, and pressure during transportation. Therefore, products will remain safe from damage and arrive in pristine condition. A larger flute size offers additional protection due to the additional cushioning and air gaps between the corrugated sheets.
Durability and Strength
Flute in case offers ideal strength to packaging. The flute sizes and thicknesses impact the weight capacity of a packaging box. Larger flutes, like the A-Flute, can withstand heavier weights, while the F-Flute ensures the least stacking strength. Businesses need to consider product weight and its usage in the supply chain when selecting an ideal flute type.
Cost Efficiency
A cardboard or paper flute is an effective packaging option. It is a lighter solution that reduces shipping expenses. The lighter packaging can lower the carbon footprint while managing the transportation charges. You can optimize packaging for cost-efficiency by choosing an ideal flute type.
Environmental Impact
Sustainability has become a major concern for businesses; corrugated cardboard fluting material provides different environmental benefits. Corrugated cardboard packaging boxes are crafted from recyclable paper, ensuring sustainable options compared to materials such as styrofoam or plastic.
The wave structure of standard cardboard thickness offers ideal strength while minimizing the requirement of material, making it an ideal option for packaging. Corrugated cardboard is a 100% biodegradable and recyclable material that is reusable, minimizing the environmental effect. Vertical vs horizontal flutes of cardboard material allow businesses to contribute to economical packaging while contributing to environmental sustainability.
What Does A Flute Look Like?
A flute looks like a cylindrical and sleek material created of plastic or metal that is used on packaging to improve product protection. These flutes are available for cardboard boxes and hard cases while ensuring ideal protection.
