Corrugated Box Material
Corrugated paperboard combines strength and adaptability, ensuring secure and efficient packaging. Moreover, the fluted inner layer strengthens protection by sitting between two flat outer layers. Therefore, this material creates multi-layered packing cases that securely store and transport goods. In addition, the corrugation process strengthens the structure and enhances functionality. In corrugated box packaging, ‘cardboard’ is a broad term for a strong material that absorbs shocks well. Consequently, Sky Print and Enterprise offer top-quality solutions, making it ideal for shipping, storage, and retail.
Thickness of Corrugated Cardboard
The flutes and liners in corrugated cardboard control its thickness, strength, and lining.
Flutes:
Flute variations define the thickness of a corrugated cardboard by measuring its board calipers in inches. Additionally, each type comes with a unique height and spacing of waves, affecting durability and cushioning. Moreover, the frequency of these flutes determines the compression strength and stacking ability of the material. As a result, tightly packed fluted board secure and protect the corrugated cardboard box. Similarly, the right combination ensures optimal performance for shipping and storage. Sky Print and Enterprise design corrugated boxes with a strong fluted structure, ensuring durability and usability for various packaging needs.
Type A Flute
This sturdy material stands out for its excellent wrapping and stacking ability. Moreover, it provides superior strength, making it a perfect choice for protecting delicate and heavy-duty cartons during delivery. Furthermore, with a durable structure, it ensures functionality and impact resistance. However, a corrugated box made with this design handles pressure smoothly, reducing the risk of damage. In addition, its composition enhances bursting strength, preventing tears or punctures under stress. As a result, this material is widely used in protective packaging, offering a reliable solution for secure transportation.


Type B Flute
Sky Print and Enterprise offers lightweight packaging solutions with type B fluting, known for its strong resistance to crushing and dents. Specifically, with a height of ⅛” and 49 flutes per foot, it enhances packaging stability. Similarly, this type adds extra protection for retail packaging and smaller corrugated packaging box solutions. In addition, it also works well as a partition for heavier loads, making it a reliable choice for secure and durable packaging.
Type C Flute
C-type fluting is a great choice for custom-engineered shipping boxes because of its paperboard thickness of 11/64″ and 39 liners per foot. Ultimately, Sky Print and Enterprise uses it for its durability, high compression strength, and resistance to crushing. Furthermore, its smooth texture supports high-quality printing and labeling, helping corrugated carton box packaging stand out while staying protective.


Type E Flute
E flute offers strong box compression strength, making it efficient for packaging. Its flat surface ensures smooth printing, while its thin, lightweight design saves space. Thus, this type works well for high-quality printing and serves as a great alternative to traditional paperboards. In particular, it is ideal for corrugated box packaging of ceramics, cosmetics, and fragile items like glassware, with a thickness exceeding 1/16” and 90 linears per foot.
Type F Flute
F flute works well for packaging consumer goods, especially in retail. It is the thinnest type, measuring it with liners per foot, giving it extra rigidity. Specifically, it uses less fiber, making it perfect for protective shipping boxes, point-of-purchase displays, jewelry, cosmetics, and shoe packaging. Therefore, many food brands also use it for clamshell containers.
In short, each type offers strong compression, stack ability, crush resistance, and flexibility.


Liner Boards
Flutes alone don’t define a corrugated cardboard’s strength; its outer layer, called “flat liner boards,” also plays a key role. For example, these liners add durability and protection, making durable paper-based boxes stronger. However they come in different types, strengthening corrugated box options to handle pressure, impact, and weight for secure packaging.
Kraft Liner
Kraft liner plays an important role in making corrugated cardboard boxes, offering durability and strength.You can find it in multiple colors and materials for diverse packaging purposes. Moreover, many businesses prefer it for its sustainable nature without compromising quality. Similarly, its gradient design makes it ideal for both retail and shipping applications. Indeed, it comes in different types like:
- Brown kraft liners
- White top liners
- White mottled kraft liners
- Bleached kraft liners
- Birch-faced kraft liners

- Notably, it consists of two outer liners and a middle layer of fluting.
- Furthermore, the order of layers is liner-fluting-liner
Double-Wall Corrugated Box
- This type serves as a tough and reliable substitute for hardwood cases.
- Similarly, the combination of three flutes and four liners makes it tough and reliable.
- Additionally, corrugated cardboard layers are arranged in this sequence like covering, ripple.


Triple-Wall Corrugated Box
This type of corrugated cardboard strengthens paperboard cartons for industrial shipping. For instance, its extra durability makes it ideal for secure cushioning.

Moreover, this solid, layered material protects products from damage and carries weight with ease. As a result, this reliable design ensures secure shipping for industrial packaging containers. Thus, companies count on it to shield products during transport and storage.
Layering
The air pockets between the layers cushion shocks and impacts, strengthening the structural packaging material. For example, these materials add strength and flexibility, keeping products safe during transportation. Similarly, the layered design works as a buffer. It also prevents damage from rough handling. As a result, with these structural packaging materials, boxes offer better protection without adding extra weight.
Versatility
Fluted fiberboard offers great versatility, allowing easy customization in size, shape, and printing. Therefore, businesses can adapt them for different packaging needs, from retail to shipping.
