PP Board — Lightweight Waterproof Polypropylene Plastic Board for Packaging, Signage & Construction
“PP board” is the most common generic search term for polypropylene plastic panels. If you have arrived here, you likely know three things: you need a plastic board, you have heard that polypropylene is the right material, and you want to quickly understand your options before contacting a supplier.
PPBOXY manufactures PP board at our Shandong facility in the format that gives this material its name: twin-wall (corrugated) polypropylene — two flat PP skins connected by parallel internal ribs that provide structural rigidity at roughly one-fifth the weight of a solid PP panel. The board is waterproof, chemical-resistant, impact-resistant, and 100% recyclable as PP #5.
The standard format is 1,220 × 2,440 mm (4 × 8 ft) in thicknesses from 2 to 12 mm. Standard colors are white, black, and blue; custom colors, sizes, and specialty grades (UV-extended, flame-retardant, anti-static, food-grade) are available. No minimum order quantity applies to standard sheets.

常见问题解答
Q: What is PP board made of?
PP board is made from polypropylene (PP), a thermoplastic polymer. It is extruded into a twin-wall (corrugated) structure — two flat skins connected by parallel internal ribs. This geometry provides high stiffness at low weight. The material is naturally waterproof, chemical-resistant, and 100% recyclable.
Q: What thickness should I choose?
2–3 mm for lightweight signage and temporary protection. 3–4 mm for yard signs, packaging inserts, and retail displays. 4–6 mm for standard construction protection and medium-duty packaging. 6–10 mm for heavy-duty packaging and structural dividers. For load-bearing applications, see PP蜂窝板 →.
Q: What is the difference between a PP board and a PP sheet?
The terms are largely interchangeable. In PPBOXY’s catalog, “board” typically indicates a finished or semi-finished panel; “sheet” indicates raw material for cutting and fabrication. The base material is identical. For a detailed comparison of all PP structures (corrugated, hollow, honeycomb, solid, FR), see PP板 →.
Q: Can PP board be used outdoors?
Yes. Standard PP board with UV stabilizers lasts 2–3 years outdoors. For permanent installations, specify the extended-life UV grade (5+ years). Black and grey colors provide the best outdoor longevity.
Q: Is PP board recyclable?
Yes — 100% as PP #5. The twin-wall structure is mono-material polypropylene with no laminates, adhesives, or mixed polymers. It can be ground, melted, and re-extruded into new PP sheet.
问：最低订购量是多少？
No minimum for standard 4×8 ft sheets in common thicknesses and colors. Custom sizes, colors, or specialty grades typically require 100–500 sheets. Contact us for a quotation based on your project specifications.
