Frequently Asked Questions
What is a PP corrugated sheet?
A PP corrugated sheet is a lightweight, twin-wall plastic panel made from polypropylene resin. It features a fluted inner core that provides structural strength while keeping the sheet light. Also known as corrugated plastic board, correx sheet, or fluted polypropylene sheet, it is widely used in signage, packaging, construction protection, and industrial applications.
What are PP corrugated sheets used for?
PP corrugated sheets are used across multiple industries: yard signs and real estate signage (outdoor advertising), packaging boxes and dividers (product protection), construction site protection boards (temporary barriers), point-of-sale displays (retail), and pallet layer pads (logistics and warehousing). Their versatility makes them a popular replacement for cardboard, wood, and metal sheets.
How long do PP corrugated sheets last outdoors?
Standard PP corrugated sheets last 6–12 months in continuous outdoor exposure. UV-stabilized versions extend outdoor life to 2–3 years. For permanent outdoor installations, darker colors (black, grey) perform better than white or clear sheets. Adding a UV-resistant coating can further extend lifespan.
Is PP corrugated sheet the same as coroplast?
Yes. “Coroplast” is a brand name for corrugated plastic sheet, similar to how “Kleenex” is used for facial tissue. PP corrugated sheet is the generic product name. Other brand names and regional terms include Correx (UK), Corflute (Australia), Cartonplast (Europe), and Twinplast. All refer to the same twin-wall polypropylene sheet product.
Can you print on PP corrugated sheets?
Yes. PP corrugated sheets are one of the most printable plastic substrates available. They accept screen printing (for high-volume orders), UV digital printing (for full-color short runs), and flexographic printing (for packaging applications). The smooth outer walls provide excellent ink adhesion and color reproduction.
How thick should a PP corrugated sheet be for yard signs?
For standard yard signs (600 × 900 mm), 3–4 mm thickness is the industry standard. For larger real estate signs (900 × 1200 mm or bigger), 4–5 mm is recommended. For highway billboard-style signs or signs in high-wind areas, 5–6 mm provides the required rigidity. H-stakes or wire stakes work with 3–4 mm sheets; heavier signs may need metal frames.
What is the difference between PP corrugated sheet and foam board?
PP corrugated sheets are waterproof, impact-resistant, and fully recyclable — ideal for outdoor and heavy-duty use. Foam boards (PVC foam, polystyrene foam) offer smoother printing surfaces and higher rigidity but are heavier, not waterproof, and difficult to recycle. For outdoor signage, PP corrugated is superior; for indoor framing displays, foam board may be preferred.
What is the MOQ for PP corrugated sheets?
We do not set a strict MOQ. Whether you need a small sample order or large-volume production, we can accommodate your requirements flexibly.
