If the FIBC feels thicker, wide, and a little hard to the touch, it means that the raw material is woven from PP flat yarn; if it feels soft, lubricated, and not dense, it means HDPE flat yarn; in addition, FIBC manufacturers will also add a masterbatch to the raw materials to change the relevant characteristics of the raw materials. For example, adding calcium masterbatch to the PP flat yarn material will make the hand feel very broad. The quality of the products can also be judged according to the different feel standards of the FIBC products, because many manufacturers will mix miscellaneous materials when producing FIBCs, which can be distinguished according to the touch feel.
