Mitigating of High Temperature and Variation in FIBC Big Bags Storage

Flexible intermediate bulk containers (FIBCs) are every kind of ‘able’ -- durable, reusable, and recyclable.

Now, while FIBCs are meant to take a lot of wear and tear, they are susceptible to temperature, whether on the outside or the inside. But of course, there are ways to mitigate the effects.

The highs…

Although the bags are designed with plastic material and polypropylene fabric woven together in individual strands to keep sensitive materials inside, high temperatures can affect the overall strength of FIBCs. Exposure to heat can loosen the molecules in the materials and result in the bag losing its tensile strength. The bag can begin degrading at temperatures above 21 degrees C. As the temperature rises further, the bag gets weaker and can break.

The lows…

Low temperatures can affect bulk bags just as much as high temperatures. Cold temperatures and rain can cause the polypropylene material to deteriorate.

Materials inside can be protected by adding a polyethylene or liquid liner, as well as using bags with an external coating. They won’t provide full waterproofing or keep the materials warm, but they will help keep your stored products safe. Also, if you are storing the bags outside in winter conditions, they will also have to be covered with waterproof material.

How to safeguard bags

In short, what’s best for the bag?

It is best to store bulk bags in areas with cool, dry temperature conditions for the best results and to extend their longevity.
