Ever heard the term “corflute” before and wondered what it referred to? Fear not, we have all the answers in this article.
Corflute is the industry name given to corrugated polypropylene, a fluted plastic which is lightweight yet rigid. The plastic is extruded to give it the large rectangular flutes all the way through it, and it has medium outdoor longevity. The name “Corflute” is actually registered to Corex but the industry has picked it up and now uses it as a generic term for fluted plastic.
The reason the sign industry loves it is because it’s cheap and easy to cut to size. It also can be used for freestanding A-frames due to its inherent strength. It comes in a variety of thicknesses but the most common for the sign industry are 3mm and 5mm. It comes in most standard colours (black, white, red, green, blue and yellow) however white is the most common.
The packaging industry and construction industry also use corflute for creating boxes or for packing out or protecting large areas. The standard sheet size is 2400mm x 1200mm although sheets can be found up to three metres long.
Corflute signs made by Perth Graphics Centre are made from high quality corflute so you can be sure you’re getting the best of the best. We also sell corflute sheets, so when you’re thinking corflute, think Perth Graphics Centre.
What is the Life span if used under the house to stop coldness coming up through floor boards and dust in the summer
Hi Bob.
Corflute is a signage and packaging product and isn’t designed to last long-term, especially under a house.
Hope this helps.

Hi Bob, while the product supplier may not guarantee any non-standard use, polypropylene can be expected to last a long time if not exposed to direct sunlight, which causes it to photodegrade (i.e. crumble) over time.
Is there any difference between corflute sheet and corrugated sheet?
Hi Deepak.
Both polypropylene corrugated sheets and corflute are the same thing.
Hi,
In a standard 2400 x 1200 sheet, which way do the flutes run?
Thanks
Hi Bob.
The flutes run down the length – along the 2400 direction.
Hope this helps,

Hi we want to use Corflute to paste a Wall Mural on, it is the same as wallpaper & arrived on the panels of 60cmx120cm. The reason why we hope to use Conflute to paste the mural to, is that our wall is v old & the plaster work is rough & not flat!
We are not in a position to make it flat either & felt using Corflute would be the answer!
Can you advise if the paste we apply will work?
With thanks, Eugene
Hi Bob,
When used as a protective spacer between marble slabs, would coreflute scratch the surface of the stone?
Thanks, Peter
Can I use it as a sheeting to cover the exposed beam in my carport?
Hi
I have gessoed core flute that had been printed on.
Then painted a painting of it in oil paints.
If hung on a wall out of the sun what would the expected lifespan be?
Thank you
Sylvia
Hi Sylvia.
Corflute isn’t a long term product outside, so around 12-18 months would be what you’d get.

Hi I want to use cor flute as a mould for casting epoxy resin would that be a problem regarding the epoxy resin bonding to cor flute
Hi Gwynne.
You can definitely use epoxy resin on corflute, but as to how long it will last is anybody’s guess. Maybe check how strong the bond between epoxy resin and polypropelene is (which is what corflute is made from).

Hello
Husband brought home an old realtor sign made from corflute. I do parties so I use it as a backdrop for dessert tables. I purchase a swatch of fabric and attach it to the board with thumb tacks. I have to apply a bit of pressure for the thumb tacks to go but it holds the fabric in place perfectly. Hubby brought home another piece but the thumb tacks go in too easily and pops right back out. My question….are there different thicknesses? Are some more sturdy than others?
Hi Psharna.
Yes, there are indeed different thicknesses. The most common are 3mm and 5mm. It sounds like the second one was 5mm thick.
Hope that helps.

Hi there,
is it known if standard core-flute has any degree of air permeability ie. can it ‘breath’ at all?
kind regards, Lisa
Hi. I wondered what type of glue I could use to put a poster on the board. Is a spray glue ok or will it affect the polypropylene? Can I use acrylic paint on the board as well. Thank you for your assistance.
Hi there Jean.
Spray glue is perfectly fine on corflute. Acrylic paint is also fine to use.
We hope that helps!

Hi,
My query is the acid content of corflute. I would think it is acid free, as I would like to use this in framing.
Cheers

Out of curiosity, needing something to slot in to a DIY sunroof on a Caravan to help deflect the heat. Would something like this work?
Should it be reinforced by something (Paint upholstery etc)
🙂
Hi Em.
Because corflute is designed as a promotional product, it’s not a long-term solution. Perhaps a white polycarbonate (Lexan) may be better suited for this purpose.
Hope that helps!
