The advantages of corflute

What is corflute?

Corflute is a brand name owned by a manufacturer specializing in the production of corrugated plastic board, which is mainly used in Australia and New Zealand to refer to the fluted polypropylene sheet and corrugated plastic board.

Corflute’s structure is two flat sheets with a ribbed center layer. Its main ingredients are polypropylene and polyethylene.

Polypropylene has a neutral ph and is resistant to many chemicals at normal normals, but can be dosed with additives to provide a variety of other resistance such as UV, anti-static, conductive, and fire resistance, for example.


Corflute started out as an alternative to corrugated cardboard. But after years of development and application, more diverse uses have been derived.
