Bring back wax coatings. And styrofoam.

• takoid 3y ago
  The issue with styrofoam (polystyrene) is that it leads to microplastics that have been found in human blood. > The scientists analysed blood samples from 22 anonymous donors, all healthy adults and found plastic particles in 17. Half the samples contained PET plastic, which is commonly used in drinks bottles, while a third contained polystyrene, used for packaging food and other products. A quarter of the blood samples contained polyethylene, from which plastic carrier bags are made.

  Pretty sure wax coatings aren't going to work for a hot cup. Have you ever accidentally put a hot drink into a cold cup (those cold cups that are wax coated)? You're left with a droopy mess of melted wax.

    years ago hot-cups were indeed wax coated, but they were generally double-walled paper. And yeah, you are right, a very hot cup of coffee when left to sit would 'precipitate' some floating wax islands atop the surface; but I think it was just presumed that the wax source (beeswax, whatever) was safe to eat. the worst thing was when you'd forget your hot cup of coffee until the next day somewhere, by which point the wax was off the paper and the liquid was out of the cup.

      even paraffin is not a significant health concern unless you consume it in large quantities and then the problem is more like Olestra.
