PP Corrugated Plastic vs. Coroplast: Are They the Same?
2026-09-03PP corrugated plastic and Coroplast are often used interchangeably, but they are not exactly the same thing. Both refer to lightweight, durable plastic sheets with a fluted or hollow structure, but there is an important difference between the two terms.
PP corrugated plastic is a general product name for sheets made from polypropylene (PP). These sheets consist of two flat outer layers connected by internal ribs, creating a lightweight structure with good strength and rigidity. PP corrugated plastic sheets are widely used for packaging, protection, signage, construction, agriculture, and industrial applications. Depending on the application, they can be produced in different thicknesses, weights, colors, sizes, and surface treatments.
Coroplast, on the other hand, is a well-known brand name associated with corrugated plastic sheets. The term “Coroplast” is sometimes used generically in the market to describe corrugated plastic, similar to how certain brand names become commonly used to describe an entire product category. However, not every PP corrugated plastic sheet is a Coroplast-branded product.

In terms of material and structure, many PP corrugated plastic sheets and Coroplast products have similar characteristics. They are lightweight, waterproof, easy to clean, reusable, and resistant to many chemicals. They can also be cut, folded, printed, and customized for different applications. Their hollow structure provides a good balance between weight and rigidity, making them an efficient alternative to materials such as cardboard in many applications.
The main difference is therefore brand versus product type. “PP corrugated plastic” describes the material and product category, while “Coroplast” refers specifically to a brand. When purchasing corrugated plastic sheets, it is important to check the actual specifications rather than focusing only on the name. Thickness, grammage, sheet size, color, surface treatment, UV stabilization, and other performance requirements can significantly affect the suitability of the product.
For businesses looking for customized packaging, protective sheets, signs, dividers, layer pads, or other plastic products, PP corrugated plastic provides a flexible solution that can be manufactured according to specific requirements. Working directly with a professional PP corrugated plastic manufacturer can also provide more options for customization, including dimensions, thickness, weight, color, printing, and special treatments.
In short, PP corrugated plastic and Coroplast are closely related, but they are not technically the same term. PP corrugated plastic is the broader product category, while Coroplast is a specific brand. Understanding this distinction can help buyers compare products more accurately and choose the right corrugated plastic sheet for their application.
