Polypropylene is most often used for single-serve containers like yogurt cups, but also shows up in reusable containers that can store leftovers. On top of being one of the FDA approved food contact materials, it's microwave safe and nonvolatile, meaning it will not react with any type of food you store in it, whether it's acidic, basic or liquid.
- chownie 3y agoAre you certain the barrels are made of polypropylene? Bic pens are composed from polystyrene in their barrels for example, being the most sold pen in the world I'd take note and carefully research whether you've been looking at the materials list for the correct part.

The Hong Kong Food and Environmental Hygiene Department recently reviewed the safety of serving various foods in polystyrene foodservice products and reached the same conclusion as the U.S. FDA.[108]https://en.wikipedia.org/wiki/Polystyrene#Safety https://en.wikipedia.org/wiki/Polystyrene#Safety
