It can also be called : PP corrugated sheet, TwinWall PP sheet or grid plate, it is a lightweight, high-strength board extruded from polypropylene (PP) resin, featuring a rectangular grid hollow core. It integrates waterproofing, corrosion resistance and recyclability, serving as an eco-friendly alternative to paperboard and plywood.
Lightweight: Density of 0.5–0.8 g/cm³, approximately 1/3 the weight of plywood and 1/5 that of metal sheets, facilitating easy handling and transportation.
High Toughness: The hollow rib structure disperses external forces, delivering excellent impact resistance, compression resistance and bending strength, with durability far exceeding that of cartons.
Waterproof & Corrosion-Resistant: Non-absorbent, moisture-proof, oil-resistant and rust-proof, suitable for humid or corrosive environments.
Eco-Friendly & Recyclable: As a thermoplastic, PP is 100% recyclable, non-toxic and odorless, complying with environmental standards.
Easy Fabrication: Can be cut, punched, bent, heat-sealed and printed without mold opening, ideal for complex structures.
Customizable Functions: Can be formulated with anti-static, conductive, flame-retardant or UV-stabilizing masterbatches for electronics, outdoor and other scenarios.
Versatile Colors: Available in custom colors for easy classification and branding.
Thickness: 2 mm–12 mm (3 mm–5 mm commonly used).
Width: 1220 mm, 1500 mm, 1800 mm, 2000 mm.
Length: Customizable (max. approx. 6000 mm).
Colors: Transparent, white, gray, blue, green, yellow, red, etc..
Structures: Standard grid, reinforced rib, anti-static, conductive, flame-retardant, etc..
Logistics Packaging (Core): Turnover boxes, partitions, divider cards, pallets, foldable crate enclosures; replaces cartons/wooden boxes for electronics, food, auto parts, etc..
Electronics Industry: Anti-static hollow boards for electronic component trays and IC packaging to prevent electrostatic damage.
Advertising & Display: Exhibition boards, signage, promotional backdrops, display stands; lightweight, printable and cost-effective.
Construction & Agriculture: Temporary partitions, wall protection, greenhouse roofs, seedling trays, livestock fencing.
Others: Stationery, toys, furniture interlayers, lightweight shelving, automotive interior panels, etc..
vs Corrugated Cardboard: Waterproof, corrosion-resistant, recyclable; service life of 10+ reuses with lower overall cost.
vs Solid Plastic Sheet: Lighter, more cost-effective, better cushioning performance.
vs PP Honeycomb Board: Grid structure for cost-effectiveness; honeycomb (hexagonal) structure for higher strength (30%–80% more expensive).
Thickness & Basis Weight: Higher thickness/basis weight means better strength and higher cost.
Color & Appearance: Smooth surface, no bubbles/cracks, uniform color.
Functional Requirements: Anti-static for electronics, UV-stabilized for outdoors, flame-retardant for flammable environments.
Supplier Qualifications: Prioritize certified suppliers with consistent quality and environmental compliance.
