Big bags are also known as flexible bulk bags, FIBCs, space bags, etc. It is an intermediate bulk container and container unit equipment that can be transported by crane or forklift. In the container bag, there are many processes in the process of manufacturing the container bag, one of which is the drawing process. The width and slight tension of the steel wire directly determine the quality of the container bag.
1. Due to the large capacity of the ton bag, it can be poured all at once or poured out all at once, which is very easy for products with a large amount of use.
2. Due to the large demand for packaging, the quality of the ton bag is very good. If it is not man-made destruction, it is still a good value for secondary use.
3. Ton bags are usually made of polypropylene, most of which are white. If used well, it can be recycled in an environmentally friendly way.
4. Ton bags, also known as container bags, have good tensile strength and strong ductility.
When drawing, after extruding the big bag, you need to pay attention to the following matters. After the extruded melt film is cooled, the appropriate knife distance is selected for cutting according to the type of flat wire. When incising, try to keep the uniformity of the equal film incision. The flat film after slitting needs to undergo thermal stretching treatment to obtain flat filaments with greater tensile force. However, in order to prevent the flat yarn from being greatly shortened in the subsequent weaving process, it should also be heat-set. After such a series of cutting and drawing tests, we can characterize the quality of the FIBC.
