Getting fresh produce from the farm to the retail shelf is a race against time. Fruits, vegetables and legumes require fast and well-planned logistics with packaging that can preserve freshness. Across Sub-Saharan Africa, post-harvest loss is a multi-billion Rand problem, often caused by the lack of suitable or breathable packaging during transit.
Farmers need a system that can actively preserve freshness to support food security and boost profits. The definitive solution for farm-to-market logistics has become the ventilated bulk bag, or flexible intermediate bulk container (FIBC). These specialised bulk bags provide optimum airflow and heavy-duty structural support to ensure produce survives the African supply chain in pristine condition.
Custom Bulk Bags (CBB) can produce up to 3.5 million bulk bags annually for multiple industries across the Sub-Saharan region, including agriculture. Our ventilated bulk bags are built to international standards for strength and quality, keeping your products secure throughout the supply chain.

Why farm-to-market logistics requires specialised packaging
Getting fresh agricultural produce from the fields to the shelves presents its own set of environmental and physical challenges. Unlike dry industrial aggregates, living produce continues to breathe after harvest, releasing moisture vapour and metabolic heat.
With fruits and vegetables packed in standard, non-breathable plastic containers or tightly sealed bulk bags, heat is trapped inside, and the temperature inside the container can spike. That results in rapid sweating, which creates a high-humidity environment for bacteria, fungal mould and rot to grow.
Farm-to-market transit also includes bouncing over secondary dirt roads and sudden climate changes. Poor packaging results in shifting loads that bruises soft skinned fruits and cracks root vegetables, which can affect their commercial value at market.

Bespoke solutions to strengthen the logistics chain
CBB produces tailor-made bulk bags, designed for the physical properties of each crop and the handling machinery of the farm. CBB customises the size, loop structure and fabric specifications to create a seamless bridge between different nodes of the agricultural sector:
- For the farmer – Integrated custom bulk bags that attach directly to automated field harvesters and sorting lines, increasing packing speeds and reducing manual labour costs.
- For the market owner – Standardised square baffled bulk bags maximise vertical warehouse space, sit neatly on pallets and are easy to move with standard forklifts without the risk of tipping over.
- For the end consumer – The bulk bags protect the produce from bruising and sweating for long-distance travel, ensuring that the produce at the local grocery store retains its nutritional value, crispness and shelf life.

Key features that make ventilated bulk bags effective
Ventilated bulk bags are advanced logistical products. To maintain the integrity and aeration of agricultural produce, CBB includes the following features in our range of breathable FIBCs:
1. Longitudinal ventilation strips – The primary feature of these bags is the presence of multi-directional ventilation panels woven directly into the polypropylene fabric. These strips allow fresh air to flow continuously throughout the core of the load, dissipating heat and preventing moisture build-up.
2. Premium UV stabilisation – Agricultural bulk bags are often left outside in fields during harvest or on open loading docks. All agricultural fabrics are treated by CBB with heavy-duty UV stabilisers as raw polypropylene degrades rapidly under intense solar exposure. This will keep the bag strong so it won’t become brittle or tear in the African sun.
3. Integrated discharge spouts – To reduce bruising during unloading, our bags can be fitted with a bottom discharge spout. This way, the processing plants or supermarket packing centres can release the produce in a controlled, gentle stream instead of dumping it from a height, preserving the aesthetic and physical quality of the harvest.

Locally-manufactured bulk bags for agriculture
The use of international packaging brokers exposes South African farmers and markets to the risks of currency fluctuations, port congestion and extreme shipping delays. CBB provides a reliable, vertically integrated alternative with world-class manufacturing facilities here in South Africa.
We focus on custom designs for all levels of South African retail, from the huge national supermarket chains and industrial food processors down to the local grocer and fresh produce market. Choosing CBB means selecting premium packaging that protects your crop, makes logistics easier and contributes to the development of the domestic industry.
