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.
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.
Benefits of Corrugated Boxes
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.
Corrugated Flute Styles
Similar to how corrugated boxes have different packaging boards, they also have various kinds of flutes. These flutes have letter designations, which include A, B, C, E, and F. Type A has excellent compression and cushioning and provides good stacking strength. Type B offers great crush and puncture resistance. Furthermore, it’s a good printing surface. As for Type C, it also has excellent printing surfaces, compression properties, and crush resistance.
Types E and F are on the thinner side of the flute styles. Types E’s thin construction helps reduce the amount of storage space it takes while providing excellent crush resistance and an ideal printing surface. It also allows for rigid boxes with less fiber. Lastly, Type F has the best printing surface and superior crush resistance. Despite its thin design, you shouldn’t underestimate its durability and strength.
Types of Corrugated Boxes
Many corrugated box styles fall into a couple of general categories: slotted boxes, telescope boxes, rigid boxes, self-erecting boxes, folders, and interior forms. As a bonus, many of these boxes can fit specific design needs for customers. So knowing the most common types of corrugated cardboard boxes will help you maximize the durability and reliability of your packages as you deliver high-quality products.
With only a single piece of corrugated fiberboard, slotted boxes come scored and slotted to permit folding. Manufacturers send them off and store them flatly, only assembling them as needed by the user. Some types include:
- Regular Slotted Container
- Half Slotted Container
- Overlap Slotted Container
- Full Overlap Slotted Container
- Center Special Slotted Container
- Center Special Overlap Slotted Container
- Center Special Full Overlap Slotted Container
Their designs are relatively similar, only varying on the flap sizes and the boxes' widths and lengths. Thankfully, they all offer outstanding durability and an excellent level of protection.
These boxes consist of top and bottom pieces. The telescope style’s top part is slightly larger than the bottom, fitting over with at least two-thirds of the depth of the base portion. The common types include FTD (Full Telescope Design Style Container), DSC (Design Style Container with Cover), and Full Telescope Half Slotted Container.
The FTD and DSC designs are two-piece boxes made from two scored and slotted blanks, while the Full Telescope Half Slotted Container is a two-piece body made of two containers with half slots. Though they vary little, the distinction comes down to having two-thirds more or less than the box depth.
Rigid and Self-Erecting Boxes
Rigid boxes include two identical end panels and bodies that fold to form two side panels, an unbroken bottom, and a top. The flaps create joints and become sealed, resulting in rigid structures. As for self-erecting packages, they typically feature either regular slotted containers or telescope-style top parts.
Folders and Interior Forms
Folders consist of one or more pieces of combined cardboard, incorporate an unbroken bottom surface, and have scores for folding around products. A couple of styles include one-piece folders, five-panel folders, and trays.
Additionally, interior forms include various buildups, partitions, dividers, and other inner packing pieces. Businesses use them to separate or cushion products, fill voids, and strengthen boxes. Some standard formats include pads, tubes, partitions, inner packing pieces, and inner pack forms.
