Corrugated Plastic Political Signs: What You Need to Know

Why the Flutes Matter

Look at the edge of a corrugated-plastic sign and you'll see channels running through it.

Those are the flutes.

With properly oriented material, wire stakes can slide into those channels.

That is why flute direction matters during production.

For a standard yard sign going onto an H-stake, the manufacturer needs to produce the sign with the appropriate flute orientation.

Why Campaigns Use Corrugated Plastic

From a manufacturing perspective, the material offers several useful characteristics:

• Lightweight
• Rigid enough for many temporary sign applications
• Printable
• Compatible with common wire stakes
• Efficient to transport compared with heavier rigid materials
• Available in common yard-sign formats

That makes it well suited to temporary outdoor signage.

Is Corrugated Plastic the Same as Coroplast?

You will frequently hear people use the word Coroplast generically.

Coroplast is a well-known brand name associated with corrugated-plastic sheet.

In everyday sign buying, people often use terms like:

Coroplast

Coroplast signs

Coroplast yard signs

corrugated plastic

interchangeably.

When getting a commercial quote, focus on the actual material specification and thickness.

4mm Political Signs

Approximately 4mm corrugated plastic is commonly used for standard yard signs.

It offers a good balance for applications where the signs need to be:

Affordable

Lightweight

Printed in volume

Installed on wire stakes

Temporary rather than permanent

For different applications, thicker or entirely different rigid materials may be worth considering.

Corrugated Plastic vs. Cardboard

They are not the same material.

Cardboard is paper-based.

Corrugated plastic is plastic-based.

For outdoor lawn applications, corrugated plastic is typically better suited to exposure than ordinary paper-based corrugated board.

One Side or Two?

Corrugated plastic can be produced with printing on one or both faces.

The decision should be driven by placement.

If the sign is against a wall or visible from a single direction, the second printed side may provide little value.

If it is installed perpendicular to two-way traffic, both sides may be useful.

Quote accordingly.

Stakes

Confirm:

• Are stakes included?
• What style?
• How many?
• Do they match the sign's flute orientation?
• Are they packed separately?

The sign is only one component of the finished installed product.

Is Corrugated Plastic Permanent?

It is generally used as a temporary sign material.

For long-term permanent outdoor signage, a different rigid substrate may be a better fit depending on the application.

Tell the printer how the sign will actually be used.

Shipping Advantage — and Challenge

Corrugated plastic is lightweight, which is helpful.

But large quantities are still bulky.

That means shipping and pallet dimensions can matter on high-volume orders.

Always compare the delivered project cost.
