Corrugated/Fluted
Corrugated & Fluted Plastic Sheets — Lightweight, Durable & Print-Ready
Laird Plastics stocks corrugated and fluted plastics for signage, packaging, agriculture, construction, and displays. Choose fluted polypropylene (PP) sign board for lightweight print jobs, or twinwall polycarbonate panels when you need higher stiffness, light diffusion, and weatherability. Cut-to-size and fabrication services available.
Use when you need: lightweight panels, easy converting (die-cut/score), moisture resistance, outdoor durability (grade dependent).
Corrugated PP Sign Board
Lightweight, printable sheets for yard signs, POP displays, wayfinding, and event graphics. Moisture-resistant and easy to convert: score, crease, die-cut, fold, rivet.
Multiwall PC Panels
High-impact, UV-stabilized panels for greenhouses, skylights, partitions, and architectural cladding. Superior stiffness-to-weight with light diffusion and insulation.
Reusable Totes, Dividers & Dunnage
Fluted PP configured for totes, bins, and part dividers. Tough, water-resistant, and long-life—ideal for kitting and closed-loop logistics.
Temporary Floor & Wall Protection
Corrugated PP sheets shield floors, counters, and walls during construction/move-in. Easy to tape down, cut to fit, and remove cleanly.
Corrugated & Fluted Plastics — Quick Facts
| Materials | Polypropylene (PP) corrugated; Polycarbonate (PC) twinwall/multiwall |
|---|---|
| Key traits | Lightweight, rigid for weight, moisture-resistant, easy to convert |
| Printing | Screen, UV inkjet, latex (check surface treatment/primer by SKU) |
| Converting | Score/crease, die-cut, CNC, fold, rivet; edge/cap profiles available for PC |
| Outdoor use | PP sign board: short- to mid-term; Twinwall PC: UV-stabilized for long-term glazing |
| Typical widths | 24", 48", 50"+; thickness (PP) ~2–10 mm; (PC) ~4–16 mm (by SKU) |
| Recyclability | PP is typically recyclable where facilities exist; PC recyclable in appropriate streams |
Fluted PP vs. Twinwall PC — How to Choose
- Fluted PP: Best for printed signs, lightweight packaging, short-term outdoor promos, low cost per panel.
- Twinwall PC: Best for glazing/roofing, partitions, higher stiffness, UV-stable long-term installs.
Application Ideas
- Signage/Graphics: yard signs, event wayfinding, retail POP.
- Packaging: totes, dividers, kitting trays, returnables.
- Building/Ag: greenhouse roofs, light-diffusing skylights, sheds.
- Protection: temporary floor/wall protection during construction.
Corrugated & Fluted Plastics – FAQs
Can I print directly on corrugated polypropylene?
Yes—most fluted PP is compatible with screen, UV inkjet, and latex printing. Verify corona treatment/primer and ink adhesion for your press.
How weather-resistant are these materials?
Fluted PP performs well for short- to mid-term outdoor signs. Twinwall PC is UV-stabilized for long-term glazing and architectural applications.
What thickness should I choose?
For PP signs, common calipers are 4 mm and 6 mm. For twinwall PC, 6–10 mm is typical for partitions/greenhouses; heavier gauges improve stiffness/insulation.
Can you fabricate returnable packaging from fluted PP?
Yes—Laird Plastics can convert fluted PP into totes, bins, and dividers with scoring, riveting, and custom inserts.
Do you offer cut-to-size and accessories?
Yes—we offer cut-to-size, CNC routing, edge/cap profiles (for PC), and finishing guidance. Contact us for a quote.
