Several factors affecting the price of FIBC

The appearance of FIBC is varied. According to the different needs of the industry, FIBCs with different shapes are designed, some are round, some are square, and some are U-shaped. Different shapes of FIBCs have different prices, so what factors will affect the FIB prices? Next, Guangxi FIBC manufacturers will analyze one or two for you.

In the process of producing FIBC, in order to meet the safety factor of the product, we should choose a base fabric with higher strength, but the strength of the base fabric is not as high as possible. We take the specific weight of the base fabric as the premise, and under the law that the tensile force and the elongation are inversely proportional, the flat yarn used in the woven FIBC should maintain a good elongation while pursuing the absolute tensile force, and there is no good elongation. Excessive pursuit of tension will be counterproductive, and the aging performance of the product will be greatly reduced. Without any additives, the elongation is one of the main indicators to judge the performance of the fabric, which is directly related to the quality of the FIBC.

Once the strength of the base fabric is determined by design, the sum of the tensile force of each monofilament cannot be equal to the measured strength of the base fabric at a predetermined width, which may have a braid loss of 5%-15%, which is different from the structure of the production equipment. There is a certain relationship, and it is also related to the melt index of the raw material of the flat yarn (soft and hard material), the ratio, and the process method. In addition, the strength loss in the weft direction is relatively larger than that in the warp direction.

Secondly, we must not add recycled materials during the production of FIBC, because this involves safety issues in the later use. We know that although polypropylene material has better mechanical properties, its ability to resist natural aging is itself very poor. If you want to maintain a relatively long-term performance, the scientific and reasonable addition of additives is an inevitable choice. If recycled materials are used, first, the composition is difficult to control, and the performance of the finished product is not easy to grasp. The above-mentioned aspects are the main factors that affect the price of FIBC. When we choose FIBC, we also choose qualified and regular manufacturers to ensure the quality of FIBC.
