Corrugated plastic is one of the most versatile, lightweight, and durable materials available in today's market. Commonly referred to as corflute, coroplast, or PP corrugated sheets, it serves a wide variety of purposes across industries such as construction, signage, packaging, horticulture, and logistics. But what exactly is corrugated plastic, and why is it so popular? This guide will explain everything you need to know, including its properties, applications, and benefits.
What Is Corrugated Plastic?
Corrugated plastic is a lightweight, twin-wall plastic material typically made from polypropylene (PP) or polyethylene (PE). Its structure consists of two smooth plastic sheets connected by fluted ridges, forming an air-filled layer that adds strength and rigidity.
Often compared to corrugated cardboard, corrugated plastic offers significant advantages. It is waterproof, resistant to chemicals, and more durable, making it ideal for indoor and outdoor applications.
Common Names for Corrugated Plastic
Corflute (commonly used in Australia)
Coroplast
Corrugated polypropylene sheets
Fluted plastic sheets
Corrugated plastic is manufactured through an extrusion process. Polypropylene resin is melted and formed into a continuous sheet, which is then cooled and moulded to create its distinctive twin-wall structure. The resulting product is lightweight yet durable, flexible yet strong.
Key Properties of Corrugated Plastic
Lightweight – Easy to transport, handle, and install.
Durability – Resistant to water, impact, and weather conditions.
Chemical Resistance – Unaffected by oils, solvents, and most chemicals.
Recyclability – Made from polypropylene, corrugated plastic is recyclable and environmentally friendly.
Cost-Effective – Affordable compared to alternatives like plywood, wood, or metal.
Customisable – Available in various colours, thicknesses (2mm to 9mm), and sizes for tailored solutions.
Corrugated plastic’s versatility makes it indispensable across multiple industries. Here are some of the most common uses:
Corrugated plastic sheets are widely used for creating durable and weather-resistant signs. UV printing ensures high-quality graphics, making them perfect for real estate signs, election campaign boards, and retail displays.
Custom-made corrugated plastic boxes are ideal for packaging sensitive items. They are reusable, foldable, and often preferred for transporting products like electronics, food, and fragile goods.
In the construction industry, corrugated plastic is used for floor protection sheets, temporary partitions, and as a lightweight alternative to plywood during construction projects.
Corrugated plastic boxes are popular for transporting fruits, vegetables, and plants due to their waterproof and chemical-resistant properties.
Durable, stackable boxes with dividers made of corrugated plastic ensure efficient organisation and transportation of goods across warehouses and supply chains.
Advantages of Corrugated Plastic
Weatherproof: Corrugated plastic is ideal for both indoor and outdoor applications because it resists rain, UV rays, and fluctuating temperatures.
Reusable and Recyclable: Unlike cardboard, corrugated plastic can be reused multiple times, reducing waste.
Customisation Options: Whether you need die-cut designs, UV-printed signage, or multi-coloured sheets, corrugated plastic can be tailored to meet your specific needs.
Easy to Work With: It can be easily cut, folded, or fabricated into different shapes and structures.
