I clicked expecting an article on a secret formula used by tupperware but was positively surprised by some pretty math in the morning. Nice breakdown, thanks!

The secret formula of Tupperware was to get people like my mother to buy it.
So. Much. Tupperware.
I mean it's very good. I have some 25 year old Tupperware in my kitchen and it's still doing absolutely great. Glass eventually breaks, Tupperware plates live. Cheap boxes sometimes break in less than a year. It's worth buying for the longevity alone.

polymers degrade, especially with heat or UV. https://www.nationalgeographic.com/environment/article/micro...
Plastics have been a blessing to us humans and a curse to nature.

Tupperware is an example of very durable and safe plastic.

Maybe our definitions of the word "safe" differ. Tupperware before 2010 had BPA in it.

"Detectable" != "unsafe".
A lot of FUD articles use that word, and your first link is probably the most factual. But FYI the only Tupperware products that have had BPA are those made using polycarbonate (PC), which is a hard and brittle plastic very different from most of their products and not the first to come to mind upon mention of the brand; on the other hand, the semi-flexible containers they're most known for are PE/PP, which don't require plasticisers at all.
