Currently, canvas tote bags bulk have become popular thanks to their usefulness in the transportation and production of most industries including agriculture, chemicals, and other industries. All over the world, jumbo bags are called FIBC - Flexible Intermediate Bulk Containers. This is a large size packaging that can hold from 500kg to 2500kg, and contain, store and transport goods to different places without being damaged. That's why the quality of bulk bags is always interesting to many businesses. So what factors affected the quality of FIBC bags? Readers can find the answer in this article with EPP.
What factors affect the quality of canvas tote bags bulk?
Jumbo bags are currently the most widely used packaging around the world. However, in the process of researching, choosing, and using big bags, many people often think that "the thicker and heavier the jumbo bag.
All over the world, jumbo bags are called FIBC - Flexible Intermediate Bulk Containers
The higher the bearing capacity and the price than the thin FIBCs". From the perspective of the jumbo bag manufacturer, the above statement is not entirely true. In particular, the quality of builder sack is affected by the following factors.
Material for producing canvas tote bags bulk
In the production process, there are many components that can be used to manufacture a Polypropylene FIBC Bulk Bag. Therefore, there will be different big bags with different qualities. The main materials are PP resins, color additives (if any), anti UV Additives (if any), other additives,... but these materials are used to form PP yarn and weave it into rolls of fabric. After that, they will be cut and sewed together to produce a complete FIBC bag.
In which the most decisive factor is the ratio of virgin PP resins in the mixture of materials. The higher the percentage of virgin PP resin, the higher the price, the better the quality.

However, for some FIBC suppliers, in order to reduce the price, they can reduce the percentage of virgin PP resins, and replace them with the ratio of recycled plastic resin and stone powder (CaCO3), which is much cheaper than virgin PP. This means that the quality and the cost will be greatly reduced.
Loading capacity of canvas tote bags bulk
To ensure the safe working load, the jumbo bag manufacturer must increase the bag thickness. However, the high ratio of stone powder and recycled plastic resins will not only reduce its elongation and breaking force but also do not guarantee safety and food hygiene (because the recycled plastic resins contain many impurities). FIBC Bulk Sacks manufactured from recycled plastic resins can not be reused many times.
Therefore, although the bag is thicker, it is still not as good as a big bag, which has a lower thickness and a high percentage of virgin PP resins. Based on the above analysis, it is clear that the thinner the jumbo bag, the cheaper the price is only true when the mixing ratio of input materials and the production technology are the same.
The safety factor of canvas tote bags bulk
After FIBC is manufactured, the finished product will be tested for the safety factor - maximum load capacity (SF - safety factor) and SWL - safe working load. In the production line of FIBC bags, the required SF according to European ISO 21898 is 5:1 and 6:1.
To ensure the safe working load, the jumbo bag manufacturer must increase the bag thickness
- SF 5:1 is required for single-use jumbo bags (single trip FIBCs). Including: Packing goods – storing in warehouses – transporting – unloading goods.
- SF 6:1 is required for multiple trip jumbo bags. Includes many cycles of use of packing – storage – transportation – discharge, until the bag shows a sign of breaking, tearing.
Above we have shared information about which factors affect the quality of canvas tote bags bulk. With the advantages that Jumbo bags bring, this will be the most useful product for storing and transporting goods today.
