Custom Bulk Bags started as a small family-owned business in 1999. Over the past two decades, the company has grown into a leading manufacturer and supplier of bulk bags for a number of industries in South Africa, including food, mining and chemicals. It is a division of Custom Extrusion which falls under the polypropylene division of Deneb Investments – a diverse investment company listed on the Johannesburg Stock Exchange (JSE).

“We have the capacity to produce up to 3.5-million bulk bags per year,” explains Chris Byram, General Manager at Custom Bulk Bags. This includes the extrusion and weaving processes, which are completed in-house. “We have numerous sizing and load options, ranging from half a cubic metre to two cubic metres and loads of 500 kg up to two tonnes,” he adds.

The options are plentiful and almost endless when it comes to bag designs and dimensions. This allows us to meet the needs of any customer, no matter their industry. Our clients are able to customise the bags and tailor their orders for specific uses and requirements. The handles, inner linings and overall designs can be specifically designed to meet the unique requirements of each customer. We are able to supply these custom bulk bags to any company operating in Africa.

Custom Bulk Bags focuses on service delivery

One of our main goals is to uphold the best customer service in the industry. “We are the only corporate entity that manufactures and supplies bulk bags in South Africa. Our backing from Deneb Investments ensures that we can meet client needs and guarantee exceptional service delivery. This sets us apart from other bulk bag companies and allows us to look after our clients’ interests above all else,” says Byram.

We are also one of the only bulk bag manufacturers in South Africa with a Level 3 Broad-Based Black Economic Empowerment (B-BBEE) accreditation. “We have the best BEE status amongst bag manufacturers in the country,” explains Byram. This status brings numerous benefits to our partners, suppliers and buyers, such as tax rebates and financial savings.

Safety and sustainability are key

Safety and sustainability form a large part of our service delivery objectives. “Custom Bulk Bags has a 5:1 safety factor, which means that our bags are able to hold 5 times the amount of their safe workload,” states Byram. The world-class engineering and precision manufacturing of our products make them extremely safe to use in all applications. Many international bulk bag brands only achieve a 3:1 safety factor.

We also strive to improve sustainability in our sector by using high-quality recycled plastics in the production of our bags. These materials are sourced from in-house rejects and are recycled for our own consumption. Not only does this help to minimise plastic waste in South African landfills but it also reduces our waste impact on the environment.

We work alongside international brands

Custom Bulk Bags has strong working relationships with international brands and suppliers. Rishi FIBC (Flexible Integrated Bulk Container) is one such bag manufacturer – an Indian company that has a high safety rating and produces some of the best bulk bags in Asia. “We have a very good trading, assistance and technology relationship with Rishi,” says Byram. “They are really supportive and are always willing to participate in training sessions with us,” he adds.

This ensures that Custom Bulk Bags employees remain at the top of their game and on-par with international manufacturers and suppliers. These business goals and the backing provided by Deneb allow Custom Bulk Bags to manufacture, supply and deliver products to clients on-time and to their satisfaction. Our customers drive our continued growth and high standards in the industry, so we push ourselves to meet their expectations and needs at every turn.
