The product processing of woven bag manufacturers requires multiple processes, and each process will affect the stability of the woven bag. Woven bag manufacturers have introduced several factors that have a great impact on the stability of woven bags.
1.Polymeric polypropylene resin is processed by extrusion. The high temperatures, shear forces and trace amounts of oxygen present during processing cause polypropylene resin to degrade. The decomposition during the processing of woven bags not only has a direct negative impact on the physical properties, mechanical properties and appearance color of the woven bag, but also has a negative impact on the stability of the plastic bag during use. Adding masterbatch to polypropylene resin to produce various polypropylene woven bags has become a common method in the plastic processing industry. Therefore, the carrier polypropylene resin of the base material accounts for a small proportion in the plastic bag, but it will become larger when heated more than twice.
2.Working temperature or thermal environment. For example, the use temperature of hot cement and asphalt increases, and the use stability of woven bags is greatly reduced. Hot cement cell damage or hot asphalt cell bonding is an example of thermal oxidative aging of cement batteries and asphalt cells.
3.The impact of fillers on the stability of woven bags, and the addition of fillers such as calcium carbonate (CaCO3) and carbon black have a negative impact on the stability of woven bags.
