What materials can be used for food filter bags?

Generally speaking, in the industrial industry, filter bags that can be used for food filtration are called food filter bags. The materials of these filter bags are also different, such as polypropylene, polyester, nylon, PTFE (polytetrafluoroethylene), etc. can be used for food filtration, these filter bags are carefully selected in strict accordance with the production process , After the mature production process, it has a good effect in filtration. Among them, nylon and polypropylene filter bags are the more common food filter bags. So, what are the advantages of these two filter bags? Next, let's follow the editor to see the relevant introduction in this article.

Polypropylene fiber (polypropylene, PP): Polypropylene has good wear resistance and high elastic recovery rate. It is an excellent thermoplastic fiber. Polypropylene felt is often used in low-temperature pulse filter bags in smelting plants and pulse filter bags in chemical and pharmaceutical factories. middle. The accuracy range of the filter bag: 0.1--500 microns, the maximum temperature of the food filter bag is 94 degrees.

Nylon wire mesh (NMO): Nylon wire mesh, also known as nylon mesh, nylon mesh, nylon mesh, is made of nylon 6 (PA6) monofilament by plain weave on a flexible rapier loom, dyed (if necessary), heat Formed. It is made of chemical synthetic fibers and belongs to the polyamide series. The food filter bag made of this material has high strength, good wear resistance, chemical resistance, water resistance and elasticity. Due to the uniform wire diameter, the surface is smooth. The disadvantage is that the stretchability of nylon mesh is relatively large.

In addition to the above, we also need to understand that food filter bags mainly filter liquids such as mineral water, beer, liquor, milk, juice, etc., and have a very good filtering effect on particulate impurities and trace suspended solids in the liquid.
