Skimmed the abstract and couldn’t see how they define “salt water”. Did not see it.
Theoretically, this has utility for shipping. So let’s say you have a pallet of water bottles. The bottles themselves will likely stay more traditional plastics. The plastic wrapping the 32 pack’s cardboard could potentially be this. The plastic wrap around the entire pallet of a bunch of stacks of those 32 packs? I… would probably still go traditional plastic, honestly.
Because a LOT of beverages are shockingly salty when you look at them (because salt is good and helps us retain water). If that is enough to even come close to triggering degradation then you lose the ability to store those bottles “indefinitely” and you drastically increase the risk that someone’s bottle breaks in their hand while they are leaving the 7-11. Which… defeats the purpose of WHY we use plastic for all this. And… it is a lot cheaper to have “one” bottle factory rather than one for each type of beverage.
As for that outermost layer? I would honestly just be terrified of a loading dock in the winter. Salt the ever loving hell out of that to minimize ice growth. And then suddenly you have pallets falling apart because of “quick” degradation.




Friendly reminder that Denmark is about 44 km^2. For context, the UK is 244 km^2
Which matters a lot. Because the various postal services around the globe? Letters are petty much a side benefit. What they are really for is delivery of important packages (e.g. medicine). Particularly to rural underserviced areas. And when you have routes that head out to the boonies 3-7 times a week, carrying a sack of letters is “free”
This? I don’t know all the details and don’t have enough of a basis to gather them from a short article. But this definitely feels like it is going to be depending on third parties for package delivery and so forth… which is what certain, really fucking stupid, countries are trying to do by privatizing/defunding their postal service.
Like I said, Denmark is tiny. They will probably be fine. But this… feels like the kind of thing that will bite people in the butt a decade or so down the line.
