A comment on A clear, strong, and thermally insulated wood for energy efficient windows.

I wonder if this is the same material I've recently come across as transparent containers sauces and the window in cardboard packaging, which are supposed to be "industrially compostable".

Cellulose films are supposed to be in this category but I've never understood how a consumer is supposed to distinguish it from plastic

The recycling label, presumably.

Those are likely just plastics.

Some of them might be PVA (though water solubility isn't really a great feature for packaging).

They say they're made from vegetable material (for the containers, I think) and wood for the window, but I don't know what that actually means, of course.

I meant the containers are just plant based plastics, with no wood in them. There's a whole bunch of processes to derive plastics from plants:

Yes, ultimately I suppose all(?) plastics are from plants, possibly via geological processes. I don't know what the legal definition would be, and the packaging which says "plastic free" might well contravene it, but at least it's (apparently) compostable.
