Corrugated Plastic Sheet — Lightweight, Durable, and Versatile
The corrugated plastic sheet (also known as a corflute or correx board) is a twin-wall structure made of polypropylene resin, featuring a hollow fluted core between two smooth outer layers.
This structure gives the sheet:
- Excellent strength-to-weight ratio
- Waterproof and chemical resistance
- Impact and tear resistance
- Easy printability and die-cutting performance
Specifications
XINSU’s corrugated plastic sheets come in:
- Thickness: 1.6mm to 12mm
- Width: up to 2600mm
- Length: unlimited, customizable
- Color options: white, blue, black, yellow, red, green, transparent, and more
- Surface options: corona-treated (for printing), anti-static, UV-resistant, or flame-retardant
These properties make XINSU sheets suitable for a wide range of applications — from protective packaging to signage and industrial use.
Correx Sheet for Printing and Promotion
One of the most popular uses for XINSU’s corrugated plastic sheets is printed signage and display boards.
Known internationally as correx boards, these sheets are an ideal substrate for UV printing, screen printing, or digital graphics.
Common Printing Applications:
- Advertising and shop promotion signs
- Election campaign boards
- Construction site safety signs
- Real estate sale boards
- Event and exhibition displays
Their smooth surface, light weight, and weather resistance make correx sheets perfect for both indoor and outdoor environments. Unlike paper-based or foam boards, they won’t warp, absorb moisture, or fade under sunlight.
Moreover, XINSU offers custom color printing and die-cut shapes, helping businesses create eye-catching promotional materials that truly stand out.
Coroplast Sheet for Bottle Layer and Industrial Packaging
In industrial applications, coroplast sheets (another name for corrugated PP sheets, especially in North America) are widely used for bottle layering, protective dividers, and interlayer pads in packaging systems.
When transporting beverages, chemicals, or medical supplies, manufacturers often need lightweight yet strong dividers to separate bottles, containers, or fragile parts.
That’s where XINSU’s coroplast sheets come in.
Advantages for Bottle Layer Application:
- Strong compression resistance — can bear heavy loads without deformation
- Waterproof and washable — reusable in wet or cold environments
- Customizable thickness and size — perfect fit for pallets or crates
- Smooth and hygienic surface — easy to clean, suitable for food and beverage industries
These reusable interlayer sheets reduce packaging waste, lower logistics costs, and provide reliable protection during storage and transportation.
5. Corrugated Plastic Box — Smart Packaging for Modern Logistics
Building on the same sheet material, XINSU manufactures a full range of corrugated plastic boxes for industrial and commercial packaging.
Compared to traditional paper cartons, XINSU plastic boxes offer a longer lifespan, better protection, and excellent reusability.
Key Features:
- Lightweight yet strong
- Waterproof and moisture-resistant
- Foldable and space-saving
- Customizable size, color, and printing
- Available with handles, dividers, and lids
These boxes are perfect for automotive parts, electronics, medical consumables, seafood logistics, and agricultural produce.
The foldable design allows users to save up to 70% storage space when the boxes are not in use — solving warehouse and transport efficiency challenges.
XINSU’s boxes can also be ultrasonic welded, riveted, or heat-bent to meet specific customer designs, ensuring both durability and easy handling.
Sustainable and Recyclable — Supporting a Circular Economy
Sustainability is becoming a global priority, and XINSU is proud to be part of the movement.
All our corrugated plastic sheets and boxes are made from 100% recyclable polypropylene (PP), with optional recycled content upon request.
Unlike paper or foam materials that degrade quickly, PP sheets can be reused multiple times and finally recycled into new products — reducing waste and saving energy.
By choosing XINSU, customers not only receive durable packaging but also contribute to eco-friendly, sustainable supply chains.
