Cardboard is one of the most popular packaging materials on the market today, widely used in various fields, from product packaging to decoration.
Behind the diversity and flexibility of cardboard lies a complex structure and multiple types of flutes.
In this article, we will explore the structure of cardboard along with the most common types of flutes in use today.

I. Basic structure of cardboard.
Cardboard typically consists of three main components.
1: Face layer (Surface): This is the surface layer of the cardboard, which is usually smooth and slightly polished, designed for printing and decoration purposes.
2: Flute layer (Middle flute): The flute layer lies between the two face layers and forms the wavy structure of the cardboard. Different flute types create varying thickness and flexibility for the cardboard.
3: Back layer (Liner): The back layer, if present, is the outermost layer that enhances strength and durability.
II. Common types of flutes.
1: E-flute.
Characteristics: E-flute is tall and thick, with wide spacing between the corrugated grooves.
Applications: Often used for heavy products such as electronics and household appliances.
2: B-flute.
Characteristics: B-flute has medium thickness and wider spacing than E-flute.
Applications: Suitable for packaging and transporting light to medium-weight products.
3: C-flute.
Characteristics: C-flute has medium thickness with slightly smaller groove spacing than B-flute.
Applications: Commonly used for packaging products such as food and beverages.
4: BC-Flute.
Characteristics: BC-flute combines both B-flute and C-flute, creating a thick and strong structure.
Applications: Suitable for packaging and protecting large, heavy products.
5: EB-Flute.
Characteristics: EB-flute combines E-flute and B-flute, providing good protection with moderate thickness.
Applications: Frequently used for packaging medium and small products.
7: BE-Flute.
Characteristics: BE-flute combines B-flute and E-flute, offering moderate thickness and excellent durability.
Applications: Suitable for packaging medium and small products.
8: CE-Flute.
Characteristics: CE-flute combines C-flute and E-flute, providing both protection and flexibility.
Applications: Often used for packaging medium and small products.
III. Conclusion.
The structure and types of cardboard flutes play a vital role in protecting and transporting products.
Understanding these flute types helps us choose and use cardboard more effectively and sustainably in both everyday life and industrial applications.
