In the food and beverage industry, there are several commonly used filter bag materials:
Food grade polypropylene (PP): Polypropylene is a commonly used food grade material with good corrosion resistance, high temperature resistance, and chemical resistance. It can effectively filter out suspended solids, particles, and solid impurities.
Food grade polyester (PE): Polyester materials have high temperature resistance and chemical stability, making them suitable for applications at higher temperatures. It has a good filtering effect on particles and can maintain the clarity and transparency of the liquid.
Nylon (PA): Nylon is a material with good wear resistance and acid and alkaline resistance, suitable for applications in the food and beverage industry that require high filtration accuracy. It can effectively filter small particles and microorganisms.
Polytetrafluoroethylene (PTFE): PTFE has excellent temperature resistance and chemical stability, and has good corrosion resistance to many chemicals. It is commonly used in the food and beverage industry to filter corrosive or high-temperature media.
When selecting the material of the filter bag, it is necessary to consider factors such as the properties of food and beverage, process requirements, filtration accuracy, as well as the corrosion and temperature resistance of the material. In addition, it is also necessary to ensure that the filter bags comply with relevant food hygiene and safety standards. It is recommended to consult a professional filter equipment supplier or engineer to select the appropriate filter bag material according to specific needs.
