Applications and Standardization Challenges of FIBC Bags in the Packaging Industry

Generally speaking, FIBC (Flexible Intermediate Bulk Container) bags that have passed the lift testing should not have any issues. If the bags do happen to fall during loading and unloading at ports, railways, or with trucks, there are only two possibilities: either there was an operational error, or the particular type of FIBC bag did not pass the lift testing.


For FIBC bags that meet a safety factor of five times or more, at least two out of the four lifting loops must have a tensile strength of over two and a half times the rated load, so even if two lifting loops were to break, the overall FIBC bag would still not have any issues.


FIBC bags have a wide range of applications, especially for packaging bulk items such as cement, grains, chemical raw materials, feed, starch, minerals, and even hazardous materials like calcium carbide. They are very convenient for loading, unloading, transportation, and storage. Currently, FIBC bag products are in a phase of development, especially for one-ton shipping and pallet forms (one FIBC bag per pallet or four FIBC bags per pallet), which are becoming more popular.


The standardization of the domestic packaging industry lags behind its development. Some standards do not match the actual production of the products and are still at a level from over a decade ago. For example, the standards for FIBC bags were set by the transportation department, for cement bags by the building materials department, for geotextiles by the textile department, and for woven bags by the plastic department, and so on. Due to the lack of targeted product use and thorough consideration of the interests between industries, there is still no unified, effective, and mutually beneficial standard.


When the lifting loops are connected to the bag body, there are various forms such as top lifting, bottom lifting, and side lifting, and they are connected by stitching, making the stitching quite important. Relying solely on the high strength of the lifting loops, base fabric, and stitching cannot guarantee the overall high performance of the FIBC bag if they do not reach a certain strength.
