Extruded Corrugated PP Panels

Extruded corrugated PP panels are premium twin-wall plastic sheets manufactured through continuous extrusion. The hollow internal rib structure delivers an exceptional stiffness-to-weight ratio, making it an ideal, cost-effective replacement for traditional corrugated cardboard, wooden crates, and solid plastic sheets.

FAQ

Q: How do I choose the correct sheet thickness and weight (GSM) for my application?

A: Sheet selection depends on load requirements, handling conditions, and structural design. Generally, 2-3 mm panels (400-600 GSM) are ideal for signage and light protection; 4-5 mm panels (700-1000 GSM) suit standard packaging and layer pads; while 6-7 mm panels (1200+ GSM) are engineered for heavy-duty automotive containers and structural dividers.

Q: What is the difference between antistatic and conductive (ESD) PP panels?

A: Antistatic panels (10^6 to 10^9 ohm/sq) prevent the buildup of static electricity and dust, suitable for general electronic housing. Conductive panels (10^3 to 10^5 ohm/sq) actively bleed off electrostatic charges rapidly, providing essential protection for highly sensitive microelectronics and semiconductor components during transit.

Q: Can these corrugated PP sheets be used outdoors long-term without degrading?

A: Standard polypropylene degrades under prolonged sunlight. For outdoor applications like real estate signs or agricultural totes, we incorporate specialized UV stabilizers (HALS) into the polymer mix to ensure 2 to 5+ years of outdoor lifespan without color fading or material embrittlement.

Q: Are corrugated PP panels a direct cost-effective replacement for cardboard?

A: While the initial unit cost of PP corrugated panels is higher than single-use paper cardboard, PP panels can be reused 50 to 100+ times and are 100% waterproof.

Q: What custom secondary processing and printing options do you offer?

A: We offer full conversion capabilities including precise die-cutting, sonic welding, custom creasing, edge-sealing (to prevent contamination), and surface Corona treatment up to 46 dyne/cm for high-adhesion screen, digital, or UV flatbed printing.
