Why Blank Corrugated Plastic Signs Are Necessary
From my experience, blank corrugated plastic signs are incredibly useful because they give me complete control over the message I want to share. Whether I’m promoting an event, directing traffic, or marking a property, having a blank canvas lets me customize every detail exactly how I need it. This flexibility is something pre-printed signs simply can’t offer.
I’ve also found that these signs are durable and weather-resistant, which means I don’t have to worry about them getting damaged quickly. Their lightweight nature makes them easy to transport and install wherever I need them. Overall, blank corrugated plastic signs provide the perfect combination of versatility, durability, and convenience that I rely on for clear, professional-looking communication.
My Buying Guides on ‘Blank Corrugated Plastic Signs’
When I first started looking for blank corrugated plastic signs, I quickly realized there’s more to choosing the right one than meets the eye. Whether you need them for yard sales, real estate, events, or business promotions, these signs offer a versatile and durable solution. Here’s what I learned along the way to help you pick the best blank corrugated plastic signs for your needs.
Understanding Corrugated Plastic Signs
Before buying, I made sure to understand what corrugated plastic signs actually are. They’re made from a lightweight, weather-resistant plastic material with a fluted design—kind of like a cardboard sandwich but waterproof and sturdier. This structure makes them durable yet easy to carry and install.
Size and Thickness Matter
One of the first decisions I had to make was about size. These signs come in various sizes, commonly 12″x18″, 18″x24″, and larger. Smaller signs work great for directional or short-term messages, while bigger ones can grab more attention for events or sales.
Thickness is another factor. Most signs are around 4mm thick, which balances durability with lightness. If you expect your signs to face heavy wind or rough handling, I recommend going for thicker options to avoid bending or damage.
Choosing the Right Color and Finish
Since I wanted to customize my signs, I opted for blank white corrugated plastic signs because they provide a clean background that makes colors pop. However, if you want something less reflective or with a matte finish, check the product details as some signs offer different textures.
Weather Resistance and Durability
I learned that corrugated plastic signs are naturally waterproof and resist fading under sunlight, which is perfect for outdoor use. Still, some brands offer UV-protected coatings for extra durability, especially if you plan to reuse the signs over multiple seasons.
Mounting and Installation Options
I also considered how I would display the signs. Many blank corrugated plastic signs come with pre-drilled holes or can be easily punched for mounting with zip ties, stakes, or ropes. If you want to insert them into stakes for yard placement, look for signs with fluted edges that allow stake insertion.
Customizing Your Sign
Since these signs are blank, you have the freedom to customize them. I used weather-resistant markers and vinyl decals, but you can also print directly on some types if you have access to a wide-format printer. Make sure the sign’s surface is compatible with your customization method.
Price and Quantity
When I was buying, the price per sign varied based on size, thickness, and quantity. Buying in bulk usually reduces the cost per piece. If you need many signs for an event or business, ordering larger quantities can save money and ensure consistency.
Where to Buy
I found blank corrugated plastic signs available at office supply stores, sign specialty shops, and online marketplaces. Online options often provide more size and quantity choices, plus customer reviews that can help gauge quality.
Final Tips from My Experience
- Always check product specifications carefully before purchasing.
- Consider your environment—windy, rainy, or sunny—and choose accordingly.
- Think about how you will display the signs and what mounting accessories you might need.
- Test one sign first if you plan to customize it yourself.
- Keep some extra signs on hand for last-minute needs.
I hope my guide makes your search for the perfect blank corrugated plastic signs easier and more informed!
