What is Correx in printing?
Correx is a fluted polypropylene board used as a lightweight waterproof board for temporary signage and displays.

Fluted means the sheet has hollow channels running in one direction between two flat plastic faces, similar to corrugated cardboard but made from plastic. The flutes keep it lightweight and help it stay stiff, and the board is usually strongest along the direction the flutes run.

Yes. Correx is polypropylene plastic, so it is waterproof and suitable for outdoor signage without absorbing moisture.
Is Correx board recyclable and what plastic is it?
Yes. Correx is polypropylene and classed as plastic type 5 PP, so it is recyclable where local facilities accept it.
