In industries ranging from packaging to advertising, the term plastico corrugado coroplast has become increasingly popular. Known for its lightweight structure, excellent durability, and wide range of applications, corrugated plastic—often called Coroplast—has grown into one of the most versatile materials on the market. Whether you are a manufacturer, distributor, or end-user, understanding what plastico corrugado coroplast is and why it is so widely used can help you make better purchasing decisions.
This comprehensive guide explains its characteristics, applications, advantages, manufacturing details, and how to choose the best type of corrugated plastic sheet for your needs.
1. What Is Plastico Corrugado Coroplast?
Plastico corrugado coroplast refers to corrugated plastic sheets made from polypropylene (PP). Coroplast is actually a brand name, similar to how “Xerox” is used for photocopy copies. Over time, it has become a general term describing fluted PP sheets used across industries.
In structure, plastico corrugado coroplast has:
- Two flat plastic surfaces
- A ribbed, fluted interior layer
- A hollow-core construction for lightweight strength
The design is similar to corrugated cardboard, but made from weather-resistant polypropylene instead of paper. This gives the material a perfect balance of light weight, rigidity, and long-term durability.
2. Key Features of Plastico Corrugado Coroplast
Understanding the characteristics of plastico corrugado coroplast helps explain why it has become so widely adopted.
2.1 Lightweight Yet Strong
The hollow-core design significantly reduces weight without sacrificing structural strength. This makes the material easy to carry, transport, and install.
2.2 Waterproof and Weather-Resistant
Unlike cardboard, Coroplast does not absorb water. It performs well in rain, snow, humidity, and even long-term outdoor exposure.
2.3 Chemical-Resistant
Polypropylene is resistant to oils, chemicals, solvents, and acids—making it suitable for industrial and laboratory settings.
2.4 Reusable and Recyclable
The material is fully recyclable, and due to its durability, it can be reused many times before replacement.
2.5 Easy to Print and Customize
Plastico corrugado coroplast supports:
- UV printing
- Silk-screen printing
- Digital printing
- Vinyl adhesive lettering
This makes it ideal for signs, display boards, and advertising.
2.6 Affordable
Compared to metal, acrylic, or solid plastic sheets, Coroplast offers excellent cost efficiency.
3. Common Applications of Plastico Corrugado Coroplast
Because of its versatility, plastico corrugado coroplast is used in dozens of industries. Below are the most common application categories.
3.1 Advertising and Signage
This is the largest market for Coroplast. Properties such as weather resistance and printability make it perfect for:

- Election campaign signs
- Storefront promotional boards
- Point-of-purchase displays
Coroplast signs are lightweight, vibrant in color, and can stay outdoors for months.
3.2 Packaging and Logistics
Plastico corrugado coroplast is widely used in packaging because it is stronger and more durable than cardboard.
Typical products include:
- Corrugated plastic boxes
- Returnable packaging
- Storage bins
- Partition dividers
- Transport trays
- Agricultural produce containers
Many companies prefer it for reusable and long-lasting supply chain packaging.
3.3 Industrial Protection and Construction
In construction, Coroplast is used for temporary surface and equipment protection. Common uses include:
- Floor protection sheets
- Scaffold protection
- Wall protection
- Cable and pipe covers
- Machine guards
It withstands impact, moisture, and dirt—keeping surfaces safe during building or renovation.
3.4 Agriculture and Gardening
Farmers and greenhouse operators use plastico corrugado coroplast for:
- Seedling trays
- Greenhouse partitions
- Tool organizers
- Weatherproof signage
Its UV resistance and ability to withstand moisture make it highly suitable for outdoor agricultural use.
3.5 Medical and Cleanroom Applications
Hospitals and laboratories prefer polypropylene-based panels because they are easy to clean and resistant to contamination.
Uses include:
- Medical transport boxes
- Cleanroom dividers
- Sterile environment signage
4. Comparison: Plastico Corrugado Coroplast vs. Cardboard vs. Acrylic
Understanding how Coroplast compares to other materials helps buyers choose the most suitable option.
4.1 Coroplast vs. Cardboard
| Feature | Coroplast | Cardboard |
|---|---|---|
| Water resistance | Excellent | Poor |
| Durability | High | Low |
| Outdoor use | Suitable | Not suitable |
| Reusability | High | Low |
| Cost | Slightly higher | Lower |
For long-term or outdoor applications, plastico corrugado coroplast is the superior choice.
4.2 Coroplast vs. Acrylic Sheets
| Feature | Coroplast | Acrylic |
|---|---|---|
| Weight | Very light | Heavy |
| Cost | Low | High |
| Printability | Excellent | Good |
| Flexibility | High | Low |
| Outdoor durability | Good | Excellent |
Acrylic is stronger and more rigid, while Coroplast is more affordable and easier to transport.
5. Manufacturing Process of Plastico Corrugado Coroplast
Corrugated PP sheets are produced using an extrusion process. The steps typically include:
- Raw Material Preparation – Polypropylene resin pellets, color masterbatch, UV stabilizers, and additives.
- Extrusion – The molten PP is pushed through a mold to form fluted sheets.
- Cooling and Shaping – Sheets are cooled to retain structure.
- Cutting – Sheets are cut into standard or customized sizes, such as 4×8 feet or 1220×2440 mm.
- Surface Treatment – Corona treatment improves printing adhesion.
The result is a rigid yet lightweight sheet ready for printing, cutting, folding, or fabrication.
6. Available Thicknesses and Colors
Plastico corrugado coroplast can be customized based on customer needs. The most common thicknesses include:
- 2 mm
- 3 mm
- 4 mm
- 5 mm
- 6 mm
- 8 mm
- 10 mm
Colors typically include:
- White
- Black
- Blue
- Yellow
- Red
- Green
- Gray
- Transparent
White Coroplast is most popular for printing, while black and blue are widely used for packaging and boxes.
