According to the detailed introduction of the experts of the tonnage bag manufacturer, the loading capacity of the FIBC is much larger than the general rotating material, so the stitching of its various parts is also particularly important. The stitching strength is the most important of the FIBC, and the stitching direction is clearly defined. And the tensile load in the direction of the bottom of the seam. The key factors that harm the strength of suture are the type and type of suture, the size of the needle, the trace of the needle, the limit of rolling or pressing the suture to the edge of the bag, the tightness and cooling method, etc.
In the specific production process of tonnage bag manufacturers, the container bag must strictly control the usage of plastic filler masterbatch, which is generally about 2%. Too much masterbatch or regenerated particles, the strength of the needle punched non-woven fabric. In order to better improve the anti-aging ability of the plastic tonnage bag container under sunlight, it is flat.
Silklash processing technology should add a certain amount of anti-purple agent and thickener.
Regarding the bulk bag, according to the Chinese standard, the compressive strength of the butt joint of the actors must reach more than 67% of the root pressure strength, and the compressive strength of the bottom butt joint of the tonnage bag manufacturer must reach more than 42% of the root pressure strength. Regarding the upper sealing of the composite valve bag, it is considered to be an emergency treatment of the seam bottom direction strength. Regarding the seam bottom direction strength of the paper bag, the overall goal is generally not achieved, so it is considered to be a glued bottom bag.
