Given the hectic schedules of retail, events, and advertising, firms need displays that attract attention while also being rugged, lightweight, and versatile. The new Corro board is ideal for those seeking a long-lasting, adjustable, and budget-friendly substrate for their displays. Corro board is the preferred choice for designing stands and displays for retail, event, and short-term use. This guide will focus on corro board, comparing it to regular corrugated board, discussing how it’s made, and exploring why professionals and businesses prefer it.
What is Corro Board?
Corroboard is commonly known as Corrugated plastic, also referred to as Coroplast, Corflute, cartonplast, Correx, polyflute, danpla, and infraboard, among others. It is made of environmentally friendly and non-toxic polypropylene. This plastic resin is extruded into a lightweight sheet consisting of two flat pieces sandwiched with evenly distributed channels or grooves. The material provides a uniquely durable and flexible structure.
Corrugated plastic is lightweight yet strong due to its structure, making it ideal for various manufacturing and industrial applications. This material can also be manufactured in many colors to match customer preferences.
Benefits of Corrugated Plastic
Corrugated plastic is lightweight yet strong due to its structure, making it ideal for various manufacturing and industrial applications. This material can also be manufactured in many colors to match customer preferences.
- Multiple usages: Corrugated plastic sheets can be used in many scenarios, usually, it’s used for making reusable and returnable packages, partitions, divider sheets, layer pads, sleeves, totes, and boxes, as well as promotion signs, campaign signs, election signs, site signs, lawn signs, and real estate signs.
- Lightweight yet durable: Due to its hollow profile structure and polypropylene characteristics, the corrugated plastic sheet is a lightweight yet durable material. It is easy to cut, convert, assemble, transport, and store. Compared to cardboard, corrugated plastic products can be used for a long time.
- Waterproof: Designed to withstand various environmental conditions, corrugated plastic is 100% waterproof. It can be used in many scenarios, such as vegetable packing boxes, plastic containers in cool houses, waterproofing substrates in the construction industry, shrimp boxes, fish boxes, pallet layer dividers for glass bottle transportation, etc.
- Cost-effective: Corrugated plastic is a very affordable material, and its price is flexible; we can produce and supply corrugated plastic products within your budget. Even if it becomes damaged, replacing it won’t cost much.
- Non-toxic: Produced from PP or PE, corrugated plastic is 100% non-toxic to the environment, humans, and animals. Corrugated plastic can withstand both low and high temperatures and won’t release harmful substances.
- Reusable: Unlike easily torn cardboard, corrugated plastic is very strong and durable, allowing you to use it repeatedly.
Corro Board vs. Traditional Corrugated Board
Although corro board and corrugated board have the same fluted core, they are not used in the same ways and do not have the same characteristics.
Feature | Corro Board (Corrugated Plastic) | Corrugated Board (Paper/Cardboard) |
Material | Polypropylene plastic | Paper-based (kraft, recycled, or virgin pulp) |
Weight | Extremely lightweight | Lightweight, but heavier than plastic |
Durability | Highly durable, weatherproof, impact-resistant | Suitable for dry environments, less weatherproof |
Printability | Excellent for vibrant, UV-resistant prints | Good, but can be affected by moisture |
Recyclability | 100% recyclable (plastic recycling stream) | 100% recyclable (paper recycling stream) |
Common Uses | Displays, signage, packaging, partitions | Packaging, shipping boxes, and retail displays |
For a long time, the packaging industry has valued corrugated board for its sturdiness, protection of products, and environmental friendliness. Although Corro Board is ideal for displays and signage that are exposed to wet conditions or handled roughly, it is made of plastic.

How is Corro Board Made?
The creation of the Corro board involves extruding copolymer-grade polypropylene (PP) through a die to form the hollow, twin-wall structure. As a result, several important things are achieved:
- Thickness: The dimensions are generally between 2mm and 10mm, depending on the application.
- Many Color Choices: With approximately 20 possibilities, your brand can maintain a consistent look while still appearing interesting.
- Special features: Anti-static, UV protection, and conductivity can be built into a Corro board with suitable additives.
The outcome is a flat and uniform board that can be trimmed, folded, or shaped to meet any display requirement.
Applications of Corro Board
The Corro board stands out for its versatility, offering numerous different uses. Here are common reasons people use it:
- Auto parts industry: Coroplast boards are widely used in car back mats. Not only that, corrugated sheets can also be used to make PP corrugated dividers for packaging auto parts, such as lights, steering wheels, and wipers.
- Sign industry: Due to its inherent strength, corflute sheet can also be used in freestanding A-frames. It comes in a variety of thicknesses, but the most common thickness in the signage industry is 3mm to 5mm. It comes in most standard colors (black, white, red, green, blue, and yellow), but white is the most common.
- Packaging industry: Utilize Corflute to create boxes for packaging a wide range of products. Whether you are a snack processing factory or a manufacturer of daily necessities, you can choose corrugated plastic packaging boxes. This kind of box is stronger than a carton, and can be waterproof, corrosion-resistant, and more cost-effective.
- Architect: Correx sheets can protect large areas. The standard sheet size is 2400mm x 1200mm, but sheets up to three meters long can also be found. Usually used to protect the ground, walls, furniture, and other items on the construction site. Correx floor protection is also one of our most exported products every year.
- IT: The packaging and transportation of electronic products require anti-static packaging materials, and Polyflute corrugated PP boards have good anti-static functions. Using ESD PP hollow sheets can better protect your electronic products from electrostatic damage.
Corro Board and the Role of SFK Paper Manufacturers
While Corro board is made from plastic, it relies on similar production and application approaches as corrugated board, which are the main products of SFK paper manufacturers. The core of corrugated board is made from SFK (Semi-Chemical Fluting Kraft) paper, which enhances the strength of the cardboard. SFK manufacturers strive to produce strong, durable paper that can be used for packaging, moving, and some advertising displays.
Corro board comes out on top when the application calls for resistance to moisture, the ability to withstand outdoor elements, or vivid color printing. Most display and packaging suppliers offer both paper-based corrugated board and plastic-based corro board, allowing customers a broad selection.
Conclusion: Make Your Next Display Stand Out with Corro Board
Looking for a display material that protects, is easy to carry, and can fit any setting? Corro board is what you need. Retailers, event organizers, advertisers, and creative professionals choose it, as it offers strength, weather resistance, printable properties, and can be recycled.
Corro board is perfect for any need, from basic signs to complex displays and reusable partitions, as it consistently delivers great value and performance. Whenever industries in displays and packaging advance, selecting partners who supply corro board, along with regular corrugated board, provides the required materials for your projects.
Seeking ways to enhance your next performance? Corro board is a good choice for results that last and look great at the same time.
