So when they make takeout containers out of this it's going to be coated with... something. I am suspicious of all these coatings they're slapping on compostable food containers these days.

- Terr_ 2y agoPerhaps some sort of food-grade wax? Although then you've got to worry about hot foods...
- Mistletoe 2y agoMy aunt got me a big wooden bowl in college and I was poor so I ate popcorn out of it. I noticed the popcorn tasted weird for quite some time. I finally put two and two together when the coating had all come off the bottom. The hot popcorn and oil had been removing the God knows what shiny finish and I had been eating it. :(
- teekert 2y agoWe’ve all eaten teflon coating at some point in our lives.
- justinator 2y agoSome of us, on purpose!
- asquabventured 2y agoHopefully just food grade mineral oil and beeswax if it was a wooden bowl.
- Mistletoe 2y agoIt was one of those you might get at Pier 1 or Kohl’s back then and had a really plasticky coating. Not my best moment.
- kaikai 2y agoUnfortunately mineral oil is derived from petroleum. I don’t care if someone says it’s food grade, I wouldn’t want to eat it.
- zdragnar 2y agoParaffin wax (chocolate), polyethylene glycol (toothpaste), vanillin (vanilla flavoring), benzaldehyde (almond flavoring), and the plastic coating on medicine pills are all derived from petroleum. You've likely been eating or using food grade petroleum products your whole life.
- blitzar 2y agoI am suspicious of the food in the takeout containers.
- sfink 2y agoWell, even vegetable oil is hydrophobic, so "something" needn't be too horrible. (Oil would obviously wipe off too easily.) Apparently soybean wax works well: https://pmc.ncbi.nlm.nih.gov/articles/PMC7435775/ https://pmc.ncbi.nlm.nih.gov/articles/PMC7435775/ Though not for hot foods. It'll only work up to 50°C.
- HeatrayEnjoyer 2y agoOr hot climates that reach >50 C

- thaumasiotes 2y agoThere's no reason you'd ever worry about that; no one can use any object in such a climate, because they'd die.
- HPsquared 2y agoPeople definitely live in places where it gets that hot. (And note that's the air temperature in the shade, not even surface temperatures in sunlight which can get much hotter). People survive because it's not 50°C all the time in those hot places. And the wet bulb temperature is lower, so sweating works (just about) to regulate body temperature. Mostly air conditioning and shelter, though.

- dwallin 2y agoThey specifically mention a coating in the abstract, parylene C.
- crimsonnoodle58 2y agoYeah that was my first thought too, "Oh great, they'll just coat it with PFAS".
