Industrial Polypropylene (PP) Hollow Sheeting
Industrial polypropylene (PP) hollow sheeting is a lightweight, extruded twin-wall plastic sheet featuring a hollow ribbed structure between two flat outer surfaces. It balances structural rigidity, impact strength, moisture resistance, and processing versatility for industrial packaging, logistics, component protection, and custom plastic fabrication.
We provide end-to-end B2B customization, supporting thicknesses from 2 mm to 7 mm and sheet widths up to 2,600 mm, with tailorable GSM (basis weight), rib geometry, custom colors, and functional additive formulations.

Functional Formulations & Additives
Standard Commercial Grade: Cost-effective solution for general protection, single-use logistics, and standard packaging partitions.
UV-Stabilized Grade: Formulated with HALS additives to prevent chalking and degradation under direct sunlight for agricultural guards and outdoor signage.
Anti-Static & ESD Conductive Grades: Surface resistivity options from 10^6 to 10^9 ohm/sq (Anti-static) or 10^3 to 10^5 ohm/sq (Conductive) for sensitive electronics and automotive parts transport.
Flame-Retardant Grade: Engineered to meet UL94 V-0 / V-2 flammability standards for building protection and indoor partition walls.
Processing & Converting Compatibility
Engineered for smooth integration with automated converting equipment and manual fabrication methods:
- Die-Cutting & Slitting: Clean profiles along or across ribs without flute crushing.
- Creasing & Folding: Precise crease lines for forming collapsible boxes, sleeve packs, and interlocking dividers.
- Printing: Factory-applied corona treatment ensures strong ink adhesion for screen, flexo, and digital UV printing.
- Joining & Assembly: Suitable for ultrasonic welding, hot-melt gluing, heat sealing, mechanical riveting, and stapling.
Key Industry Applications
Automotive Packaging: Returnable logistics containers, custom dunnage, protective dividers, and component separator trays.
Electronics Handling: ESD-safe totes, anti-static layer pads, and PCB protection partitions.
Building & Construction: Heavy-duty floor protection panels, wall/door shields, and temporary site hoardings.
Agriculture: Waterproof produce boxes, fruit transport trays, tree guards, and greenhouse partitions.
Signage & Displays: Weather-resistant point-of-sale displays, temporary outdoor signboards, and exhibition panels.
Manufacturing Quality & Order Guidelines
Production Capacity: Monthly output exceeding 1,200 metric tons, supporting large-scale global supply chains with reliable lead times.
In-Line Quality Control: Automated thickness and weight monitoring ensure consistent GSM, wall thickness, and rib formation across production batches.
Compliance Documentation: ISO 9001 certified plant. Quality, REACH, RoHS, and FDA compliance documents are available based on grade requirements.
Specifying Your Order:
- Define GSM & Thickness: Do not rely on thickness alone. Specify basis weight (g/m²) to ensure correct bending and load stiffness.
- Rib Direction: Indicate flute orientation (parallel to width or length) relative to folding lines and stacking directions.
- Surface Tension: Request corona treatment if downstream printing or gluing is planned.
FAQ
Q: How do I choose the right GSM (g/m²) for my application?
A: Basis weight (GSM) directly determines structural strength. For lightweight partitions or temporary floor protection, 400–600 GSM is usually sufficient. For heavy-duty returnable containers or high-stacking packaging, 1,000–1,800 GSM is recommended. Contact our team to match GSM with your load requirements.
Q: How long does the corona treatment last for printing?
A: Corona treatment gradually decreases over time depending on storage conditions. Our factory-treated sheets maintain a surface energy above 44 dynes/cm for up to 6 months when stored in a cool, dry place away from direct sunlight.
Q: Can you supply finished fabricated boxes instead of flat sheets?
A: Yes. In addition to flat sheeting, we offer complete OEM converting services, including die-cutting, slotting, ultrasonic welding, edge sealing, corner reinforcement, and handle installation.
Q: What is the typical MOQ and lead time for custom colors or functional grades?
A: Standard white or natural sheets have lower minimum order quantities (MOQ). Custom colors, UV, or ESD grades typically require a minimum batch size of 2 to 3 tons depending on sheet specifications.
Q: Can edge sealing be applied to the sheets?
A: Yes. We offer sealed edges (thermally welded outer flutes) to prevent dust, dirt, and moisture from entering the internal ribs. This is particularly recommended for food, agricultural, and cleanroom applications.
