For those in the Tupperware camp who just can’t believe that there are toxic heavy metals in their vintage plastic dishes, I share this with you. Below is a link to a research paper from 2015 which confirmed the presence of heavy metals in vintage plastics (specifically looking at vintage plastic toys).
This is a study of products from the same era and these are the same materials studied that the vintage Tupperware products are made of.
Please click the image below to read the full research paper. The testing methodology used in this study is also the exact same testing methodology (using the exact same instrumentation) that I use in my work.
As always, thank you for reading and for sharing my posts.
