Paper Foam Board, also known as Paper (KT) Foam Board or KT Board, is a lightweight and rigid sheet material consisting of a polystyrene foam core laminated with paper on both sides. Its low weight, excellent flatness, smooth printable surface, and easy fabrication make it a practical material for advertising, digital printing, graphic mounting, exhibitions, displays, decoration, and other visual communication applications.
As an experienced Paper Foam Board Manufacturer, Gokai supplies Paper Foam Boards for international distributors, printing companies, advertising manufacturers, display fabricators, exhibition contractors, and OEM buyers. Standard thicknesses, multiple sizes, paper weights, colors, and adhesive-backed options are available to support different production and application requirements.

Paper Foam Board is a sandwich-structured material in which a lightweight polystyrene foam core is covered with paper facings. The foam core reduces the overall weight of the board, while the paper surfaces provide a smooth and relatively rigid substrate for printing, mounting, laminating, and graphic presentation.
Unlike solid boards that can add unnecessary weight to temporary displays or large-format graphics, Paper Foam Board provides a balance between rigidity and easy handling. It can be transported, cut, mounted, and installed efficiently, making it particularly suitable for applications where visual presentation and production efficiency are equally important.
Gokai Paper Foam Board is available in different thicknesses and sizes, with options for one-side adhesive backing. This allows buyers to select a suitable configuration according to their printing process, mounting method, and final application.
Paper Foam Board is widely used in the signage and printing industries because it combines practical processing characteristics with a clean presentation surface.
The foam core gives Paper Foam Board a low overall weight compared with many solid sheet materials. Large boards can therefore be easier for workers to carry, position, cut, and install.
For advertising companies and exhibition contractors working with large graphic panels, lower weight can also simplify transportation and on-site installation.
The paper surface provides a bright, smooth substrate for graphic production. Gokai Paper Foam Board supports both one-sided and two-sided printing, including digital printing and UV flatbed printing.
This makes the material suitable for producing promotional graphics, posters, displays, presentation boards, advertising panels, and other printed visual materials where surface appearance and graphic quality are important.
Although lightweight, Paper Foam Board maintains a rigid structure that helps graphics remain flat and presentable. Good flatness is particularly important for display boards, mounted posters, exhibition graphics, and presentation materials.
The sandwich construction provides sufficient structural support for many short-term and medium-term display applications without requiring the weight of a solid panel.
Paper Foam Board can be cut and shaped using common cutting tools and suitable die-cutting equipment. This makes it practical for both manual production and larger-scale graphic fabrication.
Printing and signage manufacturers can cut boards into different shapes or sizes according to the final design, while exhibition and advertising companies can produce customized display components without complex machining processes.
Gokai offers Paper Foam Board without adhesive or with adhesive on one side. The adhesive-backed option can simplify mounting for selected graphic, promotional, and display applications.
Depending on the project, buyers can choose the appropriate backing configuration according to the required installation method.

One of the main advantages of Paper Foam Board is its suitability for printed graphics. The smooth paper surface provides a convenient base for digital printing, UV flatbed printing, graphic mounting, and other visual communication processes.
For printing companies, the material can be used to produce:
* Promotional boards
* Poster displays
* Point-of-purchase graphics
* Retail advertising
* Directional displays
* Presentation boards
* Event graphics
* Exhibition panels
* Indoor signage
* Promotional stands
The combination of low weight and a printable surface makes Paper Foam Board particularly useful when a display needs to be visually effective without becoming difficult to transport or install.
Gokai Paper Foam Board is developed for a broad range of signage, advertising, printing, display, and decorative applications.
Paper Foam Board can be used for indoor advertising boards, promotional graphics, retail displays, campaign materials, and temporary visual communication. Its easy fabrication allows graphics manufacturers to produce different panel sizes and shapes for specific campaigns.
Trade show contractors and exhibition companies often need lightweight graphic panels that can be transported and assembled efficiently. Paper Foam Board can be used for exhibition graphics, presentation panels, booth decoration, promotional displays, and temporary branded structures.
The rigid foam core provides support for mounted graphics, photographs, artwork, posters, and presentation materials. This makes KT Board useful for schools, offices, design studios, retail environments, and professional presentations.
Paper Foam Board can be used for selected advertising and promotional applications in stations, subway environments, bus-related displays, and other high-traffic visual communication areas. The specific product configuration should be selected according to the installation environment and expected service duration.
The smooth surface and lightweight structure make Paper Foam Board suitable for temporary interior decoration, wall graphics, decorative panels, retail environments, and promotional installations.
Paper Foam Board can also be used for architectural models, prototypes, presentation mock-ups, educational projects, and other applications where a lightweight board can be easily cut and assembled.
Different printing and display projects require different board thicknesses, dimensions, paper weights, colors, and backing configurations. Gokai supports a range of standard specifications as well as customized requirements for B2B buyers.
Available thicknesses include:
* 3 mm
* 5 mm
* 10 mm
Paper weights can be selected from approximately 110 gsm, 120 gsm, 150 gsm, and 210 gsm options depending on the product configuration.
Common board sizes include 700 × 1000 mm, 1220 × 2440 mm, and 1520 × 3050 mm, with customized dimensions available for specific production requirements.
The board can be supplied in white, black, red, yellow, blue, green, and other colors. Buyers can also choose between a standard backing without adhesive and a one-side adhesive option.
For large-volume purchasing, distributors and manufacturers can discuss customized dimensions, paper weight, color, adhesive backing, packaging, and order quantities with Gokai before production.

Selecting a suitable Paper Foam Board depends on the printing method, display size, installation method, and expected application period.
For lightweight promotional graphics and temporary displays, a thinner board may provide an efficient balance between rigidity and handling. For larger presentation boards or applications requiring greater structural support, a thicker board may be more appropriate.
Buyers should consider:
* Printing method
* Required board thickness
* Graphic size
* Paper weight
* Surface color
* Adhesive requirements
* Cutting and fabrication method
* Installation environment
* Required quantity
* Packaging and transportation requirements
For projects involving large-format graphics, customized sizes can also reduce unnecessary cutting waste and improve production efficiency.
