One of the core pillars of the South African economy is the mining sector. The industry continues to show incredible growth and resiliency as 2026 progresses. Industry statistics from 2025 show that the mining industry, which directly employs over 474 000 South Africans, contributed 6% to the country’s GDP.
Iron ore production increased by 12.2%, and Platinum Group Metals (PGMs) production increased by 6.2% year over year in the second half of 2025. A packaging partner that can keep up with high-volume extraction and processing is essential, given the increasing trend in mineral output.
Custom Bulk Bags (CBB) is a leading local manufacturer and supplier of customised flexible intermediate bulk containers (FIBCs). These packaging products are specially designed to satisfy the various requirements of South African mining operations by safely holding up to two cubic metres of material per bag.
Cost-savings, safety, and productivity benefits for mines
Packaging is an important choice for mines and ore processing plants as it affects multiple aspects of operations. Bulk bags are more than just flexible containers; they are advanced logistical tools that have a direct effect on a mine’s profitability.
1. Safer handling and productivity – For the sheer size of modern mines, old-school inflexible containers or small-format sacks are labour-intensive and ineffective. With a low packaging-to-product weight ratio, FIBCs can transport up to two tonnes of ore and minerals each. This improves loading and unloading times, the handling of valuable materials and improves productivity all-round.
2. Improving environmental compliance and worker safety – Mining is an inherently dangerous profession, so health and safety must take precedence. Dust management is an important consideration in mines. If not properly confined, fine mineral powders might cause serious respiratory concerns.
Sift-proof seams are the best solutions for dust containment. CBB produces bags with internal polyethylene liners and sift-proof seams to stop tiny particles from escaping during transportation. By doing this, environmental contamination is minimised, and worker health is protected.
3. Considerable cost reductions – One of the biggest overheads in mining is logistics. By doing away with the need for pricey secondary packaging, such as plastic pallets or wooden crates, FIBCs support cost-cutting measures. They also offer a higher return on investment than disposable alternatives under the appropriate Safety Factor (SF) rating, which is usually 5:1 for single-trip or 6:1 for multi-trip.
Similarly, bulk bags can fold flat when empty, so a significant amount of warehouse space can be saved. Their stackable construction maximises every square meter of a mine’s storage facility by enabling vertical storage when full.
Manufacturing in Durban
CBB is a “Proudly South African” manufacturer and supplier of bulk bags, in contrast to many other brands that depend on imports. Our national supply chain is powered by our strategically located production site in Durban.
South Africans in KwaZulu-Natal have steady jobs because of CBB’s domestic manufacturing plant. This local presence ensures that the money created by the mining industry’s supply chain remains within our borders, supporting the government’s objectives for industrialisation and economic change.
Downtime in the mining sector is valued at hundreds of thousands of Rands per hour. Relying on imported bulk bags exposes you to exchange rate instability, port congestion, and worldwide shipping delays. Mines benefit from much shorter lead times, often only weeks, as opposed to the months needed for international shipping, by sourcing from local manufacturers.
The hidden expenses of international freight and customs charges are eliminated by sourcing locally. We have complete control over the cost structure and quality because we extrude our own polypropylene fabric in-house, and we pass those savings along to our mining clients.
Customised ore and mineral storage solutions
Every mining operation is unique, and “off-the-shelf” bags are rarely enough for specialist minerals. To address the unique physical and chemical characteristics of South African ores, CBB provides an extensive array of configurable features.
We hold consultations with mining executives and operations managers to assess the unique needs before manufacturing tailored bulk bags. To determine the proper Safe Working Load (SWL) and loop configuration, our engineering team collaborates closely with mine management.
Our bags are designed to withstand the worst handling circumstances, whether you are transporting precious metal concentrates in the North West or heavy iron ore in the Northern Cape. Strong, local, and adaptable packaging is important as South Africa’s mining output rises. CBB is a partner in your business success – we are not just a supplier.
By choosing CBB, you are choosing a packaging option that improves production, increases safety, and benefits the South African economy. Please contact us today for more information about our FIBCs or to get a free consultation.
