Not sure if you're trying to make an edgy point, or if you're referring to food wax, but there are a lot of different kinds of plastics. Some of them are food safe, marine safe, temperature safe, etc - but use standardization and marking what a plastic was safe for may not have been common practice when this thermos was manufactured. Additionally, time and UV exposure can invisibly (and tasteless-ly) degrade plastic, making it unsafe.
