Given their prevalence and use in various industries, flexible intermediate bulk containers (FIBCs) have to occasionally be filled with materials that reach high temperatures throughout the packaging and transportation phases. Because of this, before implementing FIBCs into your manufacturing and shipping regiments, it is valuable to know how high-temperature products affect bulk bags and their liners. That way, you will know what to expect and how to safely follow the proper procedures when filling bags with these products.
Effects of High Temperatures on Bulk Bags
Many FIBCs are made by weaving together polypropylene. When these kinds of bulk bags are exposed to high temperatures, it can affect the bag’s structural integrity. At high temperatures, the molecules within the plastic fabric will move around more loosely. The higher the temperature, the more those molecules begin to move around. The subsequent movement of molecules stretch out the fabric of the bag, leading to tearing, ripping, and inoperability.
The potential for bag damage at high temperatures finds its most critical point at around 200 Fahrenheit. You can utilize bulk bags at these temperatures, but to ensure you reap all the benefits of your FIBCs, it’s best to follow the below procedures when doing so.
Procedures for Filling FIBCs With High-temp Products
Support any bulk bag containing high-temp granules from the bottom at all times. Do not lift it using any means other than foundational support. Wait until the fabric’s surface temperature has dropped under 100 degrees before using loops, hooks, or any other parts on the bag for immediate transportation.
Check Structural Integrity
If your company fills a bulk bag with a product that is over 200 degrees, test the bag afterward to ensure the fabric has remained uncompromised
Pay Attention to Temperatures
Be sure to think about the peak temperature, amount of exposure time and level of material stress on the bulk bag before you determine its future performance and structural integrity
Recommendations for Working With High-Temperature Materials
Indicate Bags for Higher-Temperature Materials
If you consistently ship materials that reach higher temperatures, label a set of bulk bags that are to be used specifically for that material. Higher-temperature materials will wear more on standard bulk bags. Doing so could save your business money in the long run by avoiding having to replace bulk bags frequently and can help ensure safety since all bags with potential issues will have already been labeled.
Always Test Your Bags
If you don’t test your bags, it could lead to a break and could compromise the material being transported. You will then have to pay to repackage the material, increasing time, material, and labor costs to get the project back on track.
Immediately Replace Compromised Bags
Replacing a bag immediately after you notice an issue will save you in the long run. It will help prevent accidents that could cost you much more than replacing the one bag.
Consider Specialty High-Temperature FIBCs
There are special bags available that are meant to carry high-temperature materials. Standard polyethylene bulk bags can get the job done, but a high-temperature bag would be more reliable if you transport these types of materials often. If you are using standard bulk bags to transport high-temperature materials, it will increasingly wear on them, causing you to replace the bags more often. Specialty high-temperature bags will help you save money in the long run.
