Is polypropylene (PP) a food grade material?
Not all polypropylene in polypropylene is food grade, and the polypropylene material involved in the food industry is food grade.
Food grade polypropylene materials do not dissolve harmful substances under normal and high temperature conditions, but if they are industrial grade polypropylene, harmful substances can dissolve at room temperature or high temperature, posing a threat to human health. Some of them may have a strong odor when used in food containers when exposed to heat. Therefore, when it comes to the use of polypropylene in food, it is necessary to use food grade polypropylene. If industrial grade polypropylene is used, it will cause significant harm to the human body.
Polypropylene is a high-performance thermoplastic synthetic resin, which is a colorless and translucent thermoplastic lightweight universal plastic. It has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties, and good high wear resistance processing performance. Polypropylene is widely used in the production of fiber products such as clothing and blankets, medical equipment, automobiles, bicycles, parts, transportation pipelines, chemical containers, and also in food and drug packaging.
