Fresh food and products that are susceptible to moisture might have a drawn-out trip from the farm to the market, which is a compounded problem in a globalised supply chain. Ventilated FIBCs are a must-have in situations where a lack of proper ventilation during storage and transportation can cause spoiling and severe financial losses for goods like firewood, potatoes, onions and garlic.
Ventilated FIBCs are the perfect solution in this situation. These bags protect your goods, reduce waste, and meet the needs of modern logistics because they are designed to improve airflow for certain products.
Custom Bulk Bags (CBB) is a leading manufacturer and supplier of FIBCs in South Africa. We produce 3.5 million bulk bags a year – all of which can safely hold between 500kg and 2000kg each. Our products are used by various industries to store and transport a range of foods and produce in bulk volumes.
Why airflow is important and how ventilated FIBCs are made
The woven fabric of ventilated FIBCs, which is composed of virgin polypropylene (PP) tapes, is naturally breathable due to the tiny spaces between the weave. This woven fabric is often treated to make it moisture-resistant, but this can affect breathability. On the other hand, the production method for ventilated FIBCs is designed to encourage airflow throughout the inside of the bag.
These bags have specially-designed fabric with mesh panels or ventilation strips woven right into the polypropylene fabric, rather than a solid, tightly woven structure. Without sacrificing the bag’s structural soundness or load-bearing ability, these strips provide precisely calibrated apertures that permit air to flow freely around the product.
This design addresses the most common causes of spoilage in organic produce:
- Stops the growth of mould and mildew – Humid, stagnant air is the ideal environment for the growth of mould and mildew. Ventilated FIBCs keep the product dry and healthy by preventing this buildup, by letting fresh air pass through the bag.
- Lowers temperature and moisture – Both heat and moisture are produced by fresh produce. In the absence of airflow, condensation can accumulate inside the bag, causing a “sweating” effect. This heat and moisture are dispersed by airflow, which keeps the temperature steady and stops spoiling.
- Preserves freshness and colour – By allowing products to breathe, these bags contribute to the preservation of the produce. It helps to keep organic materials firm, fresh, and vivid in colour. For potatoes and onions, where quality is determined by appearance, this is especially important.
- Prolongs shelf life – Products maintain their quality for a longer amount of time when temperature control and moisture management are combined. This is necessary for long-term storage and long-distance transportation, which will increase the product’s marketability and shelf life.
Innovations in ventilated bulk bags
Significant progress in ventilated bulk bag design has been fuelled by the need for better, more dependable packaging. With characteristics that provide improved performance and efficiency, modern ventilated FIBCs are a vast improvement over old designs.
- Advanced ventilation strip design – To guarantee a more even distribution of air throughout the bag, from the uppermost layer to the very bottom, manufacturers have improved the positioning and dimensions of ventilation strips. This is a significant improvement over previous, less effective designs since it guarantees that no product component is allowed to perspire or deteriorate.
- UV-stabilised fabric – Polypropylene fabric can deteriorate if it is exposed to sunlight for prolonged periods of time. The fabric used to make modern ventilated bags is UV-stabilised, which prolongs the bag’s life and preserves its integrity, enabling safe outdoor storage.
- Customised loop and discharge options – Manufacturers now provide a range of lifting loops and discharge spouts that can be tailored to fit various products and handling equipment. This speeds up the supply chain, reduces manual effort, and increases efficiency in filling and emptying the bags.
- Better load-bearing capabilities – Modern ventilated bulk bags are stronger and more resilient than before, mostly due to developments in material science. They can carry heavier loads with a higher safety factor, guaranteeing the safe transportation of your valuable goods.
Industries that benefit from ventilated bulk bags
Ventilated bulk bags are essential for several important sectors, including agriculture, food processing and forestry. In agriculture, potatoes, onions, garlic, carrots, and sweet potatoes are among the crops that farmers collect and store using these bags. They are also perfect for storing grains and animal feed in large quantities that must remain dry.
The forestry industry depends on these bags to store and move logs and firewood. By promoting the natural drying process, the airflow increases the wood’s marketability and flammability; no one likes damp wood for a braai.
In food processing, spices, nuts, and specific fruits and vegetables need to be kept fresh and free of mould or bacteria before they enter the processing line. These businesses and distributors prefer ventilated bags for their ideal conditions during the storage and transportation of goods.
Being picky is important when choosing a ventilated bulk bag. Look for bags with the proper ventilation type; that is to say that you need to verify that the bag’s ventilation design (full-mesh, side-panel strips, or combinations) to ensure it meets the requirements of your particular products. Verify the safe working load (SWL) to make sure there is no chance of failure and the bag can securely support the weight of your goods. Examine the stitching and fabric quality. Strong seams and sturdy fabric that can tolerate frequent handling are characteristics of a well-made bag.
Choosing the right supplier of ventilated FIBCs
Your business will be affected by the calibre of the FIBCs, as well as the services and moral behaviour of your supplier. An excellent supplier, such as Custom Bulk Bags, is a strategic partner in addition to being a source of reliable packaging products.
While assessing a manufacturer, look at their internal quality control (QC) processes. The top suppliers have specialised internal QC laboratories that examine each batch to ensure that safety and packaging regulations are being followed. The fabric, loops, and general integrity of the bag are all subjected to stringent testing.
To satisfy your particular business requirements, a good manufacturer should be able to offer solutions that are specially designed, ranging from precise measurements to specially designed lifting and discharge systems. They should also have a proven track record of successful worldwide exports, which guarantees that their packaging products satisfy a range of international shipping requirements.
Lastly, look for a manufacturer who can handle large bulk orders and provide competitive pricing without sacrificing quality, ensuring a steady and dependable supply for your business. Being a well-known supplier of ventilated FIBCs in South Africa is something that Custom Bulk Bags takes great pride in.
