Answer 1

As far as I know (as a chemistry major) glass is safer for storing acidic foods because acidity can ease the leaching of plastic toxic compounds (like epoxy resins) into the food and that’s why many acidic foods are still sold in glass jars. But then again I have seen several brands of pickels sold in plastic containers, so maybe the amount of leaching is negligible or we have to sue the companies 😀
