The ton bag is a flexible transport packaging container, which has the advantages of moisture-proof, dust-proof, radiation-resistant and firm. How is this bag stitched?
According to the introduction of the ton bag manufacturer, its loading capacity is much larger than that of ordinary rotating materials, so the sewing of various parts of his body is particularly important. Sewing strength is an important part of the FIBC, which defines the tensile load in the sewing direction and the sewing bottom direction. The key factors that affect suture strength are the type and type of suture, needle size, needle marks, the limit to which the suture is rolled or pressed to the hemming, tightness, and freezing method.
In the specific production process, ton bags need to strictly control the use of plastic filling masterbatch, generally about 2%. There are too many master batches or recycled particles, and the non-woven fabric strength is woven fabric. In order to better improve the anti-aging ability of plastic tonnage bags in sunlight, it is flat.
Regarding the big bag according to the strength and the required compressive strength of the butt joint part is more than 67%, the strength and the required bottom butt part compressive strength is more than 42% of the strength, as for the upper seal of the composite valve bag is considered It is an emergency treatment for the strength of the bottom of the seam. The bottom of the paper bag generally fails to achieve the overall goal of the strength of the bottom of the seam, so it is considered to be a paste bottom bag.
