Fluted Extruded PP Sheeting
Fluted extruded PP sheeting is a lightweight, durable, and fully recyclable hollow polypropylene panel produced through continuous extrusion. Its internal rib structure combines high flexural stiffness, impact strength, and moisture resistance, making it an ideal alternative to paper cardboard and solid plastic sheets for packaging, industrial protection, digital printing, and component fabrication.
Available in thicknesses from 2 mm to 7 mm, surface densities from 250 g/m2 to 2000 g/m2 (GSM), and widths up to 2600 mm, our sheets can be fully customized in size, color, and functional additives to meet exact OEM/ODM project requirements.

Key Performance Advantages
High Strength-to-Weight Ratio: The hollow structure significantly reduces handling and transport costs while maintaining vertical compression resistance.
100% Waterproof & Chemical Resistant: Impervious to water, humidity, oils, and common industrial chemicals, preventing structural degradation in humid environments.
Impact & Puncture Resistance: Internal vertical ribs absorb physical shock, protecting packaged goods during transit and multi-layer stacking.
Circular Economy Ready: Durable construction allows dozens of reuse cycles in closed-loop supply chains before full material recycling.
Functional Options
Weather-Resistant (UV): Inhibits yellowing and embrittlement caused by prolonged sunlight exposure in outdoor signage and agricultural applications.
Electrostatic Discharge (ESD) Control: Antistatic and conductive grades protect sensitive electronics from static buildup during handling and storage.
Flame Retardant: Engineered to self-extinguish and meet international building and transport safety requirements (UL94).

FAQ
Q: What is the difference between Fluted PP Sheeting, Coroplast, Danpla, and Correx?
A: They all refer to the same product: extruded twinwall hollow polypropylene sheeting. "Coroplast", "Danpla", and "Correx" are regional trade names or brand names widely used across North America, Asia, and Europe respectively.
Q: Why is GSM (g/m2) important when purchasing fluted plastic sheets?
A: Thickness alone does not determine board strength. GSM (Grams per Square Meter) measures the actual density and amount of material used. A higher GSM at the same thickness provides significantly higher compression strength, puncture resistance, and overall durability.
Q: How do you ensure ink adhesion for screen and digital direct printing?
A: All printable sheets undergo automated Corona Discharge Treatment, achieving a surface tension of 38 - 44 Dynes/cm. This process creates high surface energy, ensuring long-lasting ink bonding without flaking or peeling.
Q: Can fluted PP sheets be die-cut, folded, and fabricated into custom packaging?
A: Yes. Fluted PP sheeting can be processed using standard plastic conversion methods, including CNC cutting, die-cutting, slitting, creasing, ultrasonic welding, and riveting. Sheet thickness and flute orientation are factored into design to ensure smooth folding and structural integrity.
Q:What information is required to receive a fast and accurate quote?
A: Please provide the required sheet thickness (mm), surface density (GSM), dimensions (width x length), color, estimated quantity, intended application, and any functional requirements (such as UV resistance, antistatic properties, or die-cutting specifications). Attach CAD drawings or artwork files if custom fabrication is needed.
