What Are The Large Corrugated Plastic Signs?
When your message needs to be seen from a distance or withstand a challenging environment, standard corrugated plastic signs are not enough. Large corrugated plastic signs are the ideal solution for you. Made from double-walled (twin-wall) polypropylene sheets, the large corrugated plastic signs have the features of lightness,waterproofness, and high rigidity.
With super flatness, and surface corona value of 50, (higher than the industry average level 40 dyne level), the surface can firmly adhere to ink, not easy to fade for years, and have a good printing effect.
Choose The Most Suitable Large Corrugated Plastic Signs
We have many kinds of corrugated plastic yard signs for customers. The common types our customers use are as follows:
Large corrugated plastic signs for shopping centers, campuses, or industrial parks. Ideal for back-lit applications or direct printing.
Large corrugated plastic signs for trade show walls, concert stages, or exhibition backgrounds. Easy to transport and assemble.
Large corrugated plastic signs, detour arrows, or informational panels for roadworks and public events. Highly visible and impact-resistant.
Large corrugated plastic signs for covering renovations or used for temporary building wraps. Provides a smooth printable surface and weather protection.
Key Features of Large Corrugated Plastic Signs
The twin-wall hollow core structure makes it light yet rigid.
Can be cut with standard tools, routed, drilled, and welded.
It is important for large signs, which can reduce distracting sun glare and improve readability for drivers.
It resists many chemicals, and the stain can be cleaned off easily.
Exclusive Wide-Width Production Capacity
Purepack is one of the few manufacturers of large corrugated plastic signs with ultra-wide extrusion production lines. We can produce continuous sheets with a maximum width of 2600mm (over 8.5 feet) per sheet. This means that we can provide a large panel as a whole for large signage requirements.
For you, it can eliminate structural weaknesses, ensure optimal flatness, assure your large graphics or information is presented most professionally, and install faster and more stably.
We Can Offer One-Stop Solutions
As a factory, we don’t just sell large corrugated plastic signs. From raw material to being extruded into large corrugated plastic boards, to cutting and welding reinforcement according to your requirements, we control the total processing in our own factory.
You don’t have to search around; communication is easy, the sulution is customized, and delivery is faster. Whether you choose plastic corrugated sheets for self-processing or directly custom large corrugated plastic signs are accepted.
Why You Choose Purepack?
As a manufacturer of large corrugated plastic signs, we use specialized UV stabilizers to resist sunlight, and waterproof, moisture-proof, and corrosion-resistant features of the board ensure that it will not be corroded by rainwater.
We offer normal thicknesses (3-5mm), as well as additional thicknesses up to 10mm, 12mm, which can improve the impact resistance and bending stiffness of the PP corrugated board.
With rich exporting experience to over 120 countries worldwide, we customize reinforced wooden pallets for you, providing the perfect packaging solution for safe transportation.
Choosing us as your large corrugated plastic sign supplier means that you are not just choosing a seller, but choosing a partner with production capabilities and rich experience.
A major developer used our seamless 8ft tall panels to create a continuous, professional graphic wrap around a 2-year construction site. The UV-resistant material maintained color vibrancy, withstanding city pollution and weather.
For a complex interstate repair project, the contractor needed oversized, crash-resistant directional signs. Our 10mm thick, custom-cut panels are durable and with high visibility, can withstand high winds, and ensure clear driver visibility throughout the project.

Testimonials
“We needed 5000 large corrugated plastic signs for a nationwide retail rollout. Purepack not only delivered the material on spec, but their fabrication team caught a potential issue in our drawing and suggested a better solution. That saved us time onsite.”
Alan DeadmanProject Director, National Retail Contractor.“The 10-foot-tall temporary large corrugated plastic signs we ordered for our stadium renovation held up perfectly for 18 months through all seasons. The color didn’t fade, and the panels stayed perfectly flat. Their ability to handle both the scale and the durability requirements was impressive.”
Peter SaadFacilities Manager, Sports Arena.
We can custom large corrugated plastic signs according to your panel dimensions, using internal bracing and secure strapping. Our rich export experience ensures we know how to pack for safe, long-distance travel.
Our corona-treated surface is excellent for direct grand-format digital printing. Alternatively, we can supply blank corrugated plastic signs for you to apply vinyl. The direct printing is often recommended in harsh environments as there’s no laminate or vinyl to peel.
It depends on size, thickness, and wind load. We provide engineering guidelines. Typically, a welded steel or aluminum frame that slots into the flutes or is bolted through the panel is used. We can also fabricate integrated mounting channels or flanges as request.
Yes. We produce flame-retardant (FR) grades of corrugated plastic. Please specify this requirement when inquiring.
How to choose Large Corrugated Plastic Signs?
1. How to choose the thickness? ——The larger the size, the thicker the thickness
| Sign Size | Recommended Thickness | Applicable Scenarios |
| Below 24″x36″ | 4mm | Standard sizes, sufficient for most applications |
| 24″x36″ to 48″x48″ | 5–6mm | Requires moderate wind resistance |
| Above 48″x48″ | 6–8mm | Large construction hoardings, long-term outdoor signs, must be thicker |
| Over 8mm | Optional | Extra-large applications (e.g., permanent signage), consider aluminum-plastic composite panels or ribbed structures |
Notice: Once large corrugated plastic signs are too thin, they will bend and deform when the wind blows, which not only affects their appearance, but also makes it easy for the ground stakes or binding points to tear. Save a little material money, and in the end, you will receive customer complaints or afford the cost of secondary repair.
2. How to choose UV resistance? ——Observe the duration and location of use
| Usage Duration | Recommended Material | Reason |
| <1 month | Standard panel | Short-term events/promotions; UV impact is negligible |
| 1–6 months | UV-stable panel suggested | Strong UV in summer/sunny areas may cause fading/brittleness in 3 months |
| >6 months | UV-stable panel required | Long-term signage; non-UV panels risk discoloration, cracking |
| >8mm thickness | Optional | For extra-large/permanent signs; consider aluminum-plastic composite or corrugated structures |
Attention: UV-stable type directly mixes UV inhibitors into PP raw materials, not surface coatings. So it won’t peel off or wear out. If you are in areas with strong sunlight such as Australia, the southern United States, or the Middle East, they must choose UV stable type.
3. Consideration of installation method
In summary
When choosing large corrugated plastic signs, you should consider the three things:
1. Check the durability, 2. Look at the size, 3. See installation.
