What is the difference between a single wall box and a double wall box?
Corrugated cardboard is made up of a fluted paper sheet which is placed between two sheets of liner paper; an inner and an outer layer. It is the size of the 'flute' and the weight of the paper that determine the strength and performance of the board, and therefore the box. Corrugated cardboard is sold in a variety of manners; single facing, single-wall, double-wall and triple-wall. In this article, we'll be concentrating on the commonly sold stock box constructions of single and double-wall.Get more news about Packaging Boxes 1 Layer,you can vist our website!
Single Wall Cardboard Boxes are most commonly used for packaging lightweight products and are perfect for sending through the postal system.
Contrary to common belief, single wall boxes can vary considerably in quality. If you were to compare several single wall boxes that are of the same dimensional size, you'll discover that there are some surprising differences in their strength.
A single wall box is constructed using three layers of paper that are glued using starch into one single, sturdy sheet. The interior layer, called flutes or waves (the squiggly bit), play the biggest role in determining the box’s strength.
When determining which flute would be suitable for your requirements, there are many factors to be taken into consideration. Each flute has properties that may be better suited to certain packaging requirements over another.
Flutes are available in a variety of thicknesses and are identified by the use of alphabetic letters. For example, shorter flutes such as Z-flute can withstand crushing much better than the taller fluted boxes (such as C-flute). However, it's also important to understand that the shorter flutes don't absorb shock as well as the taller flutes.

Single-wall is the most commonly used type of corrugated shipping case for online merchants, as they're a cheaper alternative to double-wall versions, yet still, provide enough rigidity and shock absorption to protect the contents of the goods inside
Double Walled Cardboard Boxes are constructed using two layers of corrugated cardboard (flutes), with a liner board facing between them. This 5-ply construction provides added strength and stability.
Corrugated cases constructed in double-wall are better suited for heavier weighted or higher value items, which demand a greater strength from the board. The double fluting also adds greater protection, by providing a strong cushioning effect, absorbing any shock which may occur during transit.
The Most Common Types of Corrugated Cardboard Boxes
Sending an item from one side of the country to the other takes lots of foresight and planning. From processing the box to paying the shipment fee, it requires some patience, as well. But what is most important is the package that the product ships in.Get more news about Packaging Boxes 1 Layer,you can vist our website!
For a product to arrive safely to its destination without damage, it must remain sturdy and reliable for every client. So it’s necessary to know the most common types of corrugated cardboard boxes. This way, you can figure out the best choice to make for your shipped products. Even when delivering something as simple as a pizza, the box is what keeps it from getting messy.
What Is Corrugated Cardboard?
Corrugated cardboard, also known as corrugated fiberboard, includes all types of heavy-duty paper consisting of card stock and paperboard. It has three layers of kraft paper and gets its name from its interior layer of waxy paper, also known as the corrugated medium. It’s what provides the cardboard with its strength and durability.
The inner sheet undergoes the corrugation process during the manufacturing phase to gain stiff folds (flutes). Afterward, the manufacturer glues the corrugated medium between two sheets of kraft paper, which then become the exterior liners. This creates a three-layered structure that’s much more robust than standard cardboard.
With the layering of their cardboard, corrugated boxes offer an extra layer of stability to support a great deal of weight. They benefit the shipping process and play a vital role in supporting the transportation of food, as you can see with corrugated cardboard takeout boxes and pizza boxes.
Additionally, corrugated cardboard plays an integral role in protecting items during transportation and prevents excess damage. The arch curves in the flutes make the boards more durable and resistant to pressure from any applied angle. The spaces between the flutes and arches create extra cushioning and insulation that come in handy in extreme temperatures.
Types of Corrugated Packaging Boards
Corrugated cardboard has four different types of board styles: single face, single wall, double wall, and triple wall. Single face board has only two layers—a liner layer and a corrugated layer. It may not have as much durability as the other types of corrugated cardboard, but it often becomes incorporated inside a box for extra cushioning.
As for the three kinds of corrugated walls, single wallboard is the most common form. It's the most recognizable and consists of two outer liners and a corrugated middle layer. As for double wallboard, it has two layers of corrugated fluting and three liners. As a result, it offers more durability. Lastly, triple wallboard is the strongest, with four layers of liners and three layers of fluting.
