FDA (Food and Drug Administration)
Only seven types of plastic are considered “food grade” by the U.S. Food & Drug Administration. Plastics used to package food must be of high quality and cannot contain harmful dyes or chemicals.
Polypropylene (PP) is perfect for containing products that are bottled while hot and allowed to cool before shipment. It has a high melting point and is often used to contain foods that are packaged when hot, such as ketchup or maple syrup. It is very strong and can be used for twist-on caps and lids, such as the type on soda bottles, and drinking straws used at fast-food restaurants. Mass marketed plastic storage containers are often made of PP.
