• Is Corflute® made from Polypropylene (PP) or Polyethylene (PE)?

  Corex has been extruding Corflute® for more than 30 years.

  Traditionally polypropylene was the most suited polymer for use in Corflute® due to its printability credentials.

  Extruded polypropylene can achieve a smoother surface. When printed, the ink keys extremely well to the sheet, unlike polyethylene which has a rougher, ‘oilier’ feel to it.

  Polypropylene can also be extruded faster than polyethylene, therefore requiring less energy to produce.

  Polyethylene was initially used in some Corflute® products for horticultural applications (like tree guards) because it has better UV resistance. However, many advances have been made to additives in polypropylene which has enabled its UV resistance to now be excellent.

  Corex manufactures both solid HDPE and PP, and both are recyclable at our closed-loop facility. We choose which material to use based on product and application. Both have their unique benefits.

• What companies are included in the Corflute® Recycling Program Partner scheme?

  This program is exclusive to companies using products made by Australian manufacturer, COREX PLASTICS (AUSTRALIA) PTY. LTD. Other imported or locally made twin-wall PP sheet is not open to the Corflute® Recycling Partner Program. Corex’s goal is to show our appreciation to people using our Closed Loop Circular Economy.

• Can I recycle Corflute election signs?

  Yes you can recycle your Corflute election signs! Corflute is designed to be reused again and again, but at the end of your signs usage we invite all Corflute back for recycling.

  All processed material will be recycled and reused in products for tomorrow at Corex Plastics.

  Collect your election signage in the neighbourhood and bring it back to us, or gather it into stockpiles and we will pick it up from a consolidated point. Read more Recycle Corflute® signage from the Dunkley by-election (corex.com.au)

• What are the benefits of using plastic tote boxes over traditional cardboard totes?

  Plastic tote boxes offer enhanced durability, reusability, and resistance to moisture and chemicals, making them suitable for various industrial applications. They also provide better protection for contents during transit and storage

• What are your normal lead times?

  Although many of our products are similar, we manufacture all products to order to make sure it suits your application and brand.

  Lead-time’s vary depending on the product complexity and the amount of machine types required to make your product. Corflute® and PROMEG® products usually take 3-5 weeks to produce from the time of product sign-off.

  Large project requiring complicated processes will take longer.

  But we are able to work with your deadlines so it’s always best to tell us at your first meeting / briefing when you require delivery.

• Is Corflute recyclable?

  Yes Corflute® is 100% recyclable. Corflute® is made from Polypropylene (PP) which is 100% recyclable. Corflute is easily recyclable at recycling facilities that take polypropylene materials. Genuine Corflute® made by Corex, is invited back to Corex Recycling for recycling and reuse within products we make.

• Does cutting Corflute® produce toxic fumes?

  Corflute® is made from polypropylene (PP). PP and PE can melt or catch fire under a laser, but the fumes are not considered highly hazardous. Proper ventilation is always recommended.

  ABS, PVC, PC, and similar materials can produce toxic fumes during laser cutting.

  At Corex, we use the below methods to cut Corflute®;

  • Guillotining (to cut to size),
  • CNC using Zund and Kongsberg plotter cutter machines, and
  • Die-cutting
• When should candidates order their election corflute signs?

  Ideally candidates should begin planning and ordering election signage several weeks or months before the election campaign begins. Early planning allows time to finalise artwork, confirm quantities and secure production slots before demand increases. Ordering early also ensures your campaign receives signage in time to strategically place signs across the electorate before early voting and peak campaign activity.

• Are corflute election signs recyclable?

  Yes. Corflute signs are made from polypropylene plastic, which can be recycled and reprocessed into new plastic products. However, to ensure signs can be responsibly recycled at the end of a campaign, it’s important that they are printed on genuine polypropylene corflute material. Using Australian-made Corflute® sheet manufactured by Corex helps ensure the material can be collected and recycled after the election. If you are not purchasing your signs from Corex, ask your printer, “Are you printing my signs on genuine Corflute®?” If the answer is yes, you can recycle your signs at Corex Recycling.

• What sizes and thicknesses are available for Corflute® sheets?

  Corflute® sheets are available in standard sheets sizes of 2440mm x 1220mm, and 1830mm and 1220mm. But we manufacture Corflute® and can make any size you need within a width of 2600mm wide. We can also make longer sheets and can provide the sheet in roll format to make transportation and handling easier and more cost effective.

  General Corflute®  Sizes and Thicknesses:

  • Maximum width (dimension across flutes): 2600mm
  • Lengths (dimension along flutes): 450mm to 5000mm
  • Standard sheet sizes: 2440 x 1220 / 1830 x 1220 / 1830 x 915 / 1220 x 915 / 915 x 610
  • Roll formats up to 300 meters
  • Thicknesses: 1.9mm to 10.5mm
• Is Corflute® suitable for outdoor and long-term use?

  Yes Corflute® is the perfect material for outdoor and long-term use. Corflute® is made from durable, water-resistant polypropylene and has been tested to 3 years outdoors, but it will last much longer usually. The length of time it performs well depends on UV exposure. Contact us for a data sheet if you’d like more information.

• What is the difference between transparent and standard Corflute®?

  We make a “Natural/Clear” Corflute® which has no colour added to the mix. This product appears about 70% opaque. Opaque Corflute® has a solid master colour ingredient added to the formulation making the Corflute® sheet “solid” in colour, and you cannot see through it.

• Is Corflute® strong enough for heavy-duty applications?

  Corflute® is an excellent material for heavy-duty applications like material protection, bulk containers and transportation solutions. We can manufacture Corflute® to your specification up to 10mm thick which is extremely rigid and strong.

• Can Corflute® sheets be stacked or used for storage solutions?

  Corflute® can we layered and stacked. They will not damage each other. We can also create storge items like Corflute® warehouse picking boxes, Corflute® tote boxes, and Corflute® containers with rails along the rim to increase strength and make stacking easier.
