> Good luck finding mayonnaise or ketchup in glass jars now.

I've never seen ketchup in glass, but mayonnaise is sold in glass in all supermarkets in the Netherlands, as well as small aluminium tubes and plastic squeeze bottles.

Heinz ketchup is available in glass bottles and various other, smaller, companies offer it as well. Glass is pretty popular for "bio-ish products", at least in Germany (even though CO2eq-wise it'll usually be quite a lot worse than plastic packaging).

Oh right, the classic Heinz bottles are glass of course.

The aluminum tube is plastic-lined, else it’d dissolve.
