PP corrugated sheets are also industrially referred to as Wantong panels, grid corrugated sheets, and double-wall panels.
They belong to a category of environmentally friendly composite panels. These panels have been widely adopted in multiple industrial scenarios.
Typical application fields include logistics packaging, advertising decoration, architectural partition, photovoltaic accessories, as well as livestock breeding, storage and transportation.
The panels are mainly manufactured from thermoplastic polypropylene (PP) resin.
A certain proportion of high-density polyethylene (HDPE) resin is added as a supplementary material.
The integrated panel structure is formed via high-temperature co-extrusion molding.
This fabrication process endows the panels with a solid structure and excellent comprehensive performance.
They can be flexibly customized to meet specific application needs, making them the preferred solution for cost reduction, efficiency improvement, and eco-friendly packaging across various industries.
As a mature plastic sheet material for both industrial and consumer applications, the core advantages of PP Corrugated sheet lie in its reliable material properties and customizable functionality.
Special functional masterbatches can be incorporated during production. Anti-static and conductive masterbatches are adoptable for customized fabrication.
This approach enables the precise manufacturing of anti-static and conductive Corrugated sheet.
The modified panels satisfy the demands of electrostatic-sensitive application scenarios.
Typical applicable fields include electronic components, precision instruments, and photovoltaic modules.
Additionally, it features water resistance, moisture resistance, corrosion resistance, impact resistance, high toughness, and resistance to deformation.
Compared to traditional cardboard and wood panels, it is more durable and can be reused repeatedly, truly achieving environmental sustainability and recyclability.
Types of Corrugated sheets
In terms of specifications, our Corrugated sheets are available in thicknesses ranging from 1.5 to 8 mm.
We typically stock 3 mm, 4 mm, and 5 mm thicknesses, which are suitable for the vast majority of applications;
The weight per square meter ranges from 300 to 2,400 g/m², with a precise correlation between thickness and weight: 2 mm is approximately 300 g, 3 mm is approximately 500 g, 4 mm is approximately 700 g, and 5 mm is approximately 900 g.
You can flexibly select the appropriate option based on load-bearing capacity and strength requirements.
In terms of color, gray, blue, white, and black are the standard options, while other colors are available upon request to meet the aesthetic and branding needs of various industries.
Advantages of Hollow Plastic Sheets
Excellent Mechanical Properties
The unique hollow plastic sheet structure provides superior toughness, impact resistance, high compressive strength, cushioning properties, high hardness, and excellent bending performance.
Lightweight and Material-Efficient
Hollow plastic sheets offer excellent mechanical properties. For the same performance, they require less material, are lightweight, and have lower costs.
Insulation
Most hollow plastic panels feature a corrugated structure, providing significantly better sound insulation than solid panels, as well as excellent thermal insulation and soundproofing properties.
Wide Variety
Options include anti-static, conductive, flame-retardant, modified blends, and surface coatings.
These features enable hollow plastic panels to possess anti-static, conductive, and flame-retardant properties.
Good Chemical Stability
Plastic corrugated sheets offer advantages such as water resistance, moisture resistance, corrosion resistance, insect resistance, and fumigation-free properties, giving them a significant edge over cardboard and wood panels.
Smooth and Attractive Surface
By adding color masterbatches, they can be customized in a variety of colors. The surface is smooth, the color range is comprehensive, and they are easy to print on.
Environmentally Friendly and Recyclable
Plastic corrugated sheets are non-toxic and non-polluting. Waste disposal is simple and does not cause environmental pollution; they can be recycled to manufacture other plastic products.
Applications of Corrugated sheets
Thanks to their excellent performance and flexible customization capabilities, PP Corrugated sheets have a wide range of applications:
