What Corex Plastics does

Corex Plastics Australia is a privately held industrial plastics manufacturer founded in 1985 and headquartered in Dandenong, Victoria. The company produces twin wall profile polypropylene sheet products under its proprietary Corflute®, Fluteboard® and Promeg® brands, alongside HDPE solid sheet extrusions — and is the only domestic manufacturer of twin wall profile Corflute® and Fluteboard® in Australia. Its portfolio extends into converted products such as tote boxes, picking boxes, hangsell displays, ring binders, hospital folders, tree guards, Truckboards® freight separators, Cor-Vent® roof ventilation strips, and the proprietary Corpak® intermediate bulk containers (IBCs). An ecorange® line markets the world's first 100% carbon neutral plastic sheet range.

The business operates a vertically integrated model that spans design and engineering, rapid prototyping, print and fabrication, bespoke solutions, and a closed-loop Corflute® Recycling Program which converts end-of-life material into recycled polypropylene (r-PP) pellets sold as a standalone product. In April 2026 the company launched Corex Lab, an internal polymer science laboratory providing material testing and specification support to customer design teams. The technology stack is rooted in thermoplastic extrusion rather than software or AI.

Corex sells primarily through an enterprise field-sales motion — phone-led direct engagement and quote-based pricing for custom orders — supplemented by a self-service website catalogue for standard products. It serves six vertical markets: retail and signage, food packaging, building and construction, horticulture, food and beverage production, and supply chain. Named enterprise customers include Bluescope, ORORA, Spicers, Geofabrics, Eco-bin, IDC Solutions, Transformed Plastics, Design Flow and API. The company employs 101-250 people and operates as a single-jurisdiction (Victoria, Australia) manufacturer with a domestic-only distribution footprint.
