PETG is food safe. However! Because FDM is full of gaps, cracks, and voids, NEVER use it to store food that can spoil. Food bits can get trapped in these voids and present a persistent risk for foodbourne illness.
Granulated sugar would be fine if it's kept very dry, however do note that said voids will not make an airtight container. So I wouldn't even use it for stuff affected by humidity or oxygen.
If anything I'd almost suggest clearing the inside with a food safe platinum silicone, which should solve most of these issues.
I've seen people suggesting coating the inside of the print in some sort of coating to make it theoretically food safe.
That said I wouldn't trust it. We already have enough microplastics in our bodies. I don't want the microplastic farm anywhere near my food.
I see! Thanks! Will definetly look into that solution! I do wonder which of these foods would need it tho. The sugar I use is cubed so I reccon that be fine? The Tea is in bags so they are probably fine, how about Salt? I don't think salt goes bad yea?
