What are Breathable Bulk Bags? Top 5 Things to Know

 



FIBCs are the most popular industrial packaging solution offering you multiple benefits rolled into one single package. Constructed of interwoven polypropylene fibre, FIBC Bulk Bags are not only lightweight and strong but are naturally ventilated. For specific product categories, you must use only breathable Bulk Bags to keep them from getting spoiled.

Let us explore more about breathable Bulk Bags, their scope of application, and the benefits that you can derive out of these FIBCs.

How are FIBCs breathable?

Strands of polypropylene (PP) are woven together to form a mesh-like fabric that is used to construct FIBC Bulk Bags. This mesh-like construction allows air to flow freely within the bag, creating an apt environment for products like fresh agricultural produce to retain their freshness. All Bulk Bags are breathable to some extent owing to the PP fabric they are made of, except for bags that are laminated with an additional layer of polypropylene to create a barrier for air and moisture.

What are the factors affecting the breathability of FIBCs?

The factors that affect the breathability of FIBCs are the closeness of the weave, additional vents, and the absence of coatings or laminates. The looser the weave, the more breathable is the bag. A laminated coating inside or outside a Bulk Bag prevents adequate airflow. Ventilation strips down the sides of these bags enhance their breathability factor. Consult experts to understand the kind of ventilation your product needs.

Does breathability affect the strength of the containers?

No, it doesn’t. Owing to their mesh-like construction, FIBCs are very strong, tear-resistant, yet flexible and lightweight. Unbelievable but true, this versatile industrial packaging solution has the lowest package to product weight ratio. A standard Bulk Bag weighing 5 – 7 pounds can carry one metric tonne of product easily. 

Where to use breathable FIBCs?

The majority of products like fruits and vegetables, grains, seeds, animal feed, fertilizer, etc. need ventilation during storage or in transit to retain their quality. As such these products are handled in uncoated Bulk Bags that are super breathable, preventing them from getting spoiled. 

Additional breathability feature 

Customise your FIBC Bulk Bags with additional breathability features for extra air circulation. You can ask your supplier to add ventilation strips down the side of the Bulk Bags for enhanced air circulation. These ventilated or vented Bulk Bags are modelled variously like open-top or bottom-vented and may include a duffel or a flap. Vented bags are extensively used to handle non-flowable products like firewood or fresh produce.

Umasree Texplast has, over the years built an expertise in manufacturing and supplying Bulk Bags of both coated and uncoated variants for a cross-section of industries. Consult our packaging specialists today for the best-fit breathable FIBCs for your product.
