A cardboard display is rarely made from just one type of “cardboard.” In most custom retail displays, several paper-based materials are combined, with each layer performing a specific job.
The main structure is typically made from corrugated board, while a separate printed paper or paperboard sheet may be mounted onto it to create the visible graphic surface. Adhesives, surface finishes and additional corrugated reinforcement can also become part of the finished display.
That is why a material specification may mention terms such as corrugated board, linerboard, fluted medium, CCNB, coated paper, kraft liner, adhesive and lamination in the same document.
These materials are not necessarily alternatives. More often, they describe different parts of the same display construction.
This article explains what those materials are, where they sit within the display and what each one contributes to the finished structure.
What Materials Are Used in a Cardboard Display?
A typical custom cardboard display may contain the following materials and components:
| Material or Component | Main Role |
|---|---|
| Corrugated board | Main structural material |
| Linerboard | Flat outer layers of corrugated board |
| Fluted medium | Internal corrugated layer |
| Printed top sheet | Graphic and branding surface |
| CCNB / coated paperboard | Common printable face material |
| Kraft paper / kraft liner | Liner or visible natural paper surface |
| Adhesive | Bonds material layers and selected components |
| Coating / lamination | Finishes and protects the printed surface |
| Corrugated reinforcement | Adds structural support where required |
Not every display uses every material in this list.
A compact counter display may have a relatively simple construction. A larger floor display may use several structural panels, printed face sheets and hidden reinforcement pieces.
It is therefore more useful to think of a cardboard display as a layered material system than as a single sheet of cardboard.
Corrugated Board: The Main Structural Material
For many retail displays, corrugated board forms the main structural body.
It can be used for:
- side panels
- back panels
- shelves
- bases
- headers
- product trays
- internal supports
Unlike flat paperboard, corrugated board contains an internal wave-shaped layer positioned between flat liners.
A basic corrugated board structure looks like this:
Outer Liner
↓
Fluted Medium
↓
Inner Liner
Together, these layers create a lightweight structural panel with the stiffness required for folded display components.
Linerboard
Linerboard forms the flat faces on the outside of the corrugated medium.
Its job is not purely cosmetic. The liner helps create a stable panel and protects the internal corrugated structure.
Its main functions include:
- creating a flat exterior surface
- protecting the fluted medium
- contributing to panel stiffness
- helping the board hold its shape
- providing a suitable surface for printing or lamination
A typical corrugated panel has a liner on each side of the fluted medium.
The visible face may be kraft-colored, white or covered by a separately printed sheet, depending on the final appearance of the display.
Fluted Medium
The fluted medium is the wave-shaped paper layer between the liners.
Its geometry creates the space between the two flat surfaces and gives corrugated board much of its thickness and rigidity.
The fluted medium helps to:
- create board thickness
- separate the liner surfaces
- increase panel stiffness
- resist compression
- help structural parts retain their form
If you look at the cut edge of a corrugated display panel, the repeating wave pattern inside the board is the fluted medium.
Different flute constructions are available for different applications, but flute selection is a separate engineering topic.
For understanding the material itself, the key relationship is straightforward:
The liners form the flat outer faces, while the fluted medium creates the internal corrugated structure. Together, they make the corrugated board.
Printed Paper and Paperboard: The Graphic Surface
The material that carries the display graphics is not always the material responsible for structural strength.
This distinction matters in branded retail displays, where visual presentation and structural performance often come from different layers.
A common construction looks like this:
Printed Paper or Paperboard
↓
Adhesive
↓
Corrugated Board
The upper layer carries the artwork.
The corrugated board underneath forms the structural panel.
This explains why a material specification may list both a printable paperboard grade and a corrugated board specification.
Printed Top Sheet
A printed top sheet is the paper or paperboard layer that carries the main display graphics.
It may include:
- brand colors
- product imagery
- promotional messages
- campaign graphics
- product information
- visual merchandising elements
The sheet can be printed separately and then mounted onto corrugated board.
The finished panel combines two distinct functions:
a printable graphic surface + a corrugated structural substrate
The top sheet is mainly responsible for appearance. The corrugated board underneath provides the structural body.
Keeping these two roles separate makes material specifications much easier to understand.
CCNB
CCNB, or Clay-Coated News Back, is one paperboard material commonly used as a printable face sheet.
It has a coated printing surface on one side and a darker or gray-toned reverse side.
In a cardboard display, CCNB may be printed first and then laminated onto corrugated board.
The construction can be represented simply as:
Printed CCNB
↓
Adhesive
↓
Corrugated Board
In this arrangement:
- the CCNB carries the graphics
- the corrugated board forms the main structural panel
If both CCNB and corrugated board appear in the same material specification, they are therefore not necessarily competing options. They may refer to two separate layers within one finished panel.
Coated Paper and Paperboard
Other coated papers and paperboards can also be used as printable face materials.
Their smoother surfaces are suited to applications that require:
- detailed graphics
- clean text reproduction
- a uniform white surface
- controlled brand presentation
- a refined printed appearance
When structural rigidity is also required, the coated sheet can be combined with corrugated board.
The two materials serve different purposes: one presents the graphics, while the other supports the structure.
Kraft Paper and Kraft Liner
Kraft paper or kraft liner can appear in several parts of a cardboard display.
It may be used as:
- a liner within corrugated board
- an exposed outer surface
- part of the visible natural kraft appearance
A visible kraft face does not always mean that another decorative layer has been added. In some constructions, the shopper is simply seeing the outer kraft liner of the corrugated board.
For example:
Display A
Printed white top sheet
- corrugated board
Display B
Visible kraft liner
- corrugated structure
Both are cardboard displays, but the visible surface materials are different.
Adhesives and Surface Layers
Structural board and printed paper make up most of the display, but thinner materials may also sit between or above these main layers.
Two common examples are adhesives and surface finishes.
Adhesives
Adhesives are used wherever separate layers or selected structural parts need to be joined.
Typical applications include:
- mounting a printed top sheet onto corrugated board
- joining selected panels
- fixing reinforcement pieces
- securing pre-glued sections
One of the most common material relationships is:
Printed Top Sheet
↓
Adhesive
↓
Corrugated Board
The adhesive is usually hidden once the display is finished, but it remains part of the construction. Its function is to hold separate materials together so that the finished panel behaves as one piece.
Coatings and Laminations
A coating or lamination may be applied over the printed face of the display.
Unlike the liner and fluted medium, these treatments sit on the surface rather than inside the corrugated structure.
They may be used to:
- alter the surface appearance
- change the surface feel
- help protect printed graphics
- reduce normal handling marks and surface scuffing
Matte, gloss and other coating or lamination options are examples of this type of surface treatment.
These finishes affect the visible face of the display. They do not replace the corrugated board as the main structural material.
Reinforcement Materials
Some areas of a cardboard display may need more support than others.
Shelves, bases or internal sections can therefore contain additional reinforcement that is not obvious from the finished exterior.
In many cases, the reinforcement is itself made from corrugated or other paper-based material.
Typical examples include:
- additional corrugated shelf layers
- folded internal supports
- reinforced base panels
- doubled structural panels
- hidden vertical supports
- internal dividers
A shelf, for example, may look like a single printed panel when viewed from the front. Underneath, there may be another folded corrugated piece supporting that visible surface.
The same principle can apply inside the base or behind other structural sections.
For this reason, the amount of corrugated material inside a display may be greater than what can be seen from the outside.
Reinforcement remains part of the material construction even when it is hidden from the shopper.
How the Material Layers Work Together
A typical printed cardboard display becomes easier to understand when its materials are viewed from the outside inward.
A simplified material stack may look like this:
Surface Coating or Lamination
↓
Printed Top Sheet
↓
Adhesive
↓
Corrugated Board
├── Outer Liner
├── Fluted Medium
└── Inner Liner
↓
Optional Corrugated Reinforcement
Each layer has a distinct role.
Printed Surface
Carries the artwork, brand graphics and other visual information.
Adhesive Layer
Bonds the printable surface to the structural board.
Corrugated Board
Forms the main structural panel.
Linerboard
Creates the flat outer faces of the corrugated board.
Fluted Medium
Forms the internal corrugated structure.
Reinforcement
Adds material in selected structural areas where additional support is required.
Not every cardboard display uses exactly the same combination of layers.
The underlying principle, however, remains the same:
A cardboard display is usually built from several functional paper-based materials working together, rather than from one uniform sheet of cardboard.
A Simple Example of Cardboard Display Construction
Consider a typical printed floor-standing retail display.
From the shopper’s point of view, the visible elements may simply be:
- printed side panels
- printed shelves
- a branded header
- displayed products
Behind those surfaces, the construction may include several material layers.
For example:
Visible Graphic Surface
Printed paperboard
↓
Bonding Layer
Adhesive
↓
Structural Panel
Corrugated board
↓
Inside the Corrugated Board
Liner + fluted medium + liner
↓
Hidden Structural Areas
Additional corrugated supports
The finished display brings these visual and structural materials together into one construction.
Calling it simply “cardboard” is convenient, but it does not fully describe what the display is made from.
FAQ About Cardboard Display Materials
What is the main material used for cardboard displays?
Corrugated board is one of the most common structural materials used in cardboard retail displays.
It combines flat liner layers with an internal fluted medium. This construction allows the board to form shelves, side panels, bases and other structural parts.
A separate printed paper or paperboard sheet may be added when the display requires a different graphic surface.
Is a cardboard display made from one type of cardboard?
Not necessarily.
A custom display can combine corrugated board, printed paper or paperboard, adhesives, surface finishes and reinforcement materials.
Each material serves a different purpose within the finished construction.
What is the difference between corrugated board and a printed top sheet?
Corrugated board forms the main structural body, while the printed top sheet carries the graphics.
The printed sheet can be laminated onto the corrugated board so that the finished panel combines a branded surface with a rigid structural substrate.
What is CCNB used for in cardboard displays?
CCNB, or Clay-Coated News Back, can be used as a printable face material.
It may be printed separately and then laminated onto corrugated board.
In that construction, the CCNB carries the artwork while the corrugated board underneath provides the main structural support.
Do cardboard displays contain materials other than paper?
Some designs may include secondary components such as hooks, clips or other merchandising accessories.
The main body of many cardboard retail displays, however, is still built primarily from corrugated board, paperboard and other paper-based materials.
Understanding the Materials Behind a Cardboard Display
A finished cardboard display can look simple from the outside, yet several material layers may sit behind the visible graphics.
The most useful distinction is between:
- corrugated board for the structure
- linerboard and fluted medium within that board
- printed paper or paperboard for graphics
- adhesives for bonding
- surface treatments for the visible finish
- additional corrugated material for reinforcement
Knowing what each layer does makes material specifications easier to read and gives agencies, retail teams and brand owners a clearer basis for discussing a custom display project.
