That’s a ton of manual labor on a disposable container. Manual labor is extremely expensive, and plastics manufacturing is extremely repeatable and extremely cheap at scale (that’s kind of the big reason plastic is so common, it’s cheap and reliable)
Granted I could imagine a machine which fills it with dyed water, uses a camera to determine the fill level then passes to another machine which adjusts by volume but that’s really going to slow down the production line doing all of that.
Ultimately plastics manufacturing is way more precise and consistent than that, you’ll basically end up with either a milk jug or a misshapen mess if there is a defect, and not really anything in between

So the mold is made, the volume checked, adjusted via an insert, and then they crank out jugs.
That’s plausible, but over-complicated in an age of digital CAD and mature molding techniques.
Sounds like milk bags are vastly superior.

Apart from when you want to use them.

Spoken like someone who’s never used them.

Milk specifically, no, other bagged liquids, yes. An absolute pain in the ass compared to a bottle.
