When your Corflute® IRRI-Cor products are ready to retire, Corex can recycle and reprocess them creating a circular economy.

We supply industrial size recycling bins called Corpaks® to our clients and partners.


New to Corex and not sure how we work? Here are some answers and some helpful tips!

  • What is Corflute®?
    Corflute® is tradmarked by Corex Australia. Corflute is a proprietary twin wall profile plastic (polypropylene) sheet used in packaging and high-end graphic solutions. Corex Range includes Corflute®, Fluteboard®, Imageboard®, Versamount® and 100% Recycled Corflute®. Learn more
  • Do you offer a plastic recycling service?
    Corex has accepted material for recycling of all our products for over 20 years, and established our Corex Recycling stand-alone facility in 2009. We pride ourselves on our reduced footprint and have been trail-blazers in recycling and reusing plastics, well before the current narrative about circular economy was coined. Corex products are designed to be reused again and again. When the product is ready to retire or if you have post-industrial waste, we can collect it, recycle it, and reuse it. Every sheet of Corflute® is invited to be brought back. We supply industrial size recycling bins called Corpaks to our clients and partners. We take back a range of other plastics for recycling also. If you would like plastic or Corflute recycled, contact us and we will provide a recycling solution that suits your location and product. Our Corex Recycling facility works alongside the factory that produces Corflute.
  • Is Corflute® waterproof?
    Corflute® is waterproof. It is a great solution for use in wet packing locations like hydro-cooling and refrigeration. Corflute is also an excellent solution for outdoor signage, like bollard and fence advertising.
  • What is Corflute® made from?
    Corflute is made from a type of fluted plastic called polypropylene that is both lightweight and solid. Usually 3mm or 5mm in width, Corflute’s structure is two flat sheets with a ribbed center layer. Due to being made from plastic, Corflute can be used for printing bright and colourful signs.
  • Which plastic sheet is best for UV resistance? PP or HDPE?
    Both PP and HDPE provide good chemical and UV resistance, however PP requires stabilisation with additives, while generally PE has better UV resistance compared to PP. PE may be preferred in those applications where UV resistance is important.
  • What happens to the plastic that’s brought back to Corex Recycling?
    We process and recycle every kilogram of plastic we receive on site. All of the processed material returned to us have a use within Corex Plastics. In the rare occasion that Corex Plastics do not have a use to suit the recycled polymer, we will only then sell to local plastic manufactures that make products that could be sent back to us for recycling.

  • Are your products made in Australia?
    Our Corflute sheet and fabricated products are all made on site in Dandenong South Victoria, Australia. Our Corex Recycling facility works alongside the factory that produces Corflute®, creating a fast and efficient service with sustainability at top of mind.
