Custom Bulk Bags is a manufacturer and supplier of flexible intermediate bulk containers (FIBCs), also known as bulk bags, in South Africa. The company is owned by Deneb Investments Limited, a subsidiary of Hosken Consolidated Investments (HCI), both of which are listed on the Johannesburg Stock Exchange (JSE).

These parent companies provide support to Custom Bulk Bags through their business network and enable us to focus on producing quality FIBCs. Custom Bulk Bags can fulfil bulk orders placed by agriculture, mining and chemical companies thanks to the capital investment provided by Deneb and HCI.

Q: How long have you been associated with Custom Bulk Bags?

Q: What progress has excited you the most?

Piet: In the short period that I have been CEO, the most exciting and rewarding experience is to see how people can develop and, at the same time, create a culture of care and continual improvement.

Chris: I believe that the ease of transformation, from a family-owned and managed business to a company with good corporate governance and an intrapreneurial flair, has been a massive step in the right direction.

Q: How have your customers benefitted from the products?

Piet: The biggest benefit for our customers is the care and attention to detail in our bulk bags. This promotes good quality and on-time deliveries.

Chris: Our customers appreciate the attention to detail, combined with swift decision making, irrespective of whether you are a small, medium or large customer.

Q: What is unique about your team?

Piet: We have a blend of old and young people; the unique part is that the older people want to share knowledge and experiences, while the younger group are incredibly keen to absorb and improve. It is a fantastic match which is not often found.

Chris: The fact that we are all able to fulfil more than one position in the business, from sales to manufacturing to finance, is quite unique.

Chris: Quick turnaround time, from receipt of order to your goods being delivered to your warehouse.

Q: One thing people don’t know about you…
