What Is C Flute Cardboard?

C flute cardboard is a common type of corrugated board used in packaging. Corrugated cardboard consists of three layers: an inside liner, an outside liner, and a fluted (wavy) layer in between. The "C flute" refers specifically to the shape and size of that middle layer. With around 39-43 flutes per foot, this structure offers a good balance between **strength and cushioning**.

Why Is C Flute So Popular?

Great Balance of Strength and Thickness

C flute is about 4 mm thick, which makes it strong enough to hold medium-weight products while still being space-efficient. It can absorb shocks and bumps during shipping, which makes it ideal for protecting products in transit.

Good Print Surface

Another benefit is that it has a relatively smooth surface. This is important for businesses who want to use custom-printed packaging. Logos, branding, or vibrant designs can be printed clearly on boxes made with C flute material.

Where Do You See It Used?

This type of cardboard is everywhere! It’s often used for:

Shipping cartons
Retail display boxes
Food packaging
Electronics and appliance packaging

Because of its reliable structure, C flute is chosen across many industries that require durable yet presentable boxes.

How Does It Compare to Other Flutes?

C flute sits between A flute (thicker, better for heavy-duty shipping) and B flute (thinner, more rigid). If you're looking for a "one-size-fits-most" type of board, C flute is often the best choice. It combines the cushioning of A flute and the compactness of B flute.

Should You Use C Flute?

If you need a packaging material that is strong, versatile, and printable, C flute cardboard is a top choice. It offers a professional look with protective qualities—perfect for both e-commerce shipments and retail shelves.
