What are the colloquial names for juice boxes like the one below of children's size?
A juice box, also called a carton or popper, is a small container used to conveniently carry and consume drinks (most often juice). They are frequently made of paperboard with an aluminum foil lining, but variations exist. Juice boxes are most popular with children, although other uses include emergency drinking water and wine.

I've only ever heard these called juice boxes. I was not aware of any other name for them. But you've actually answered your own question in your question, with the information from the wikipedia article you linked:

I've never heard carton or popper, but those might be regional terms (or BrE?). I'd just stick with calling them juice boxes. But the answer is in the question!
"Popper" is an Australian term which I think comes from how when you're finished you can blow the carton up and jump on it to make a "pop" sound (although not too certain on this). I think however that this is a regional variation within Australia even as some people (esp. Victorians and Tasmanians) call it a "Juice box" and have no idea what Im talking about when I say Popper
In British they’re cartons, just not necessarily juice cartons, rather cartons of juice. A bit long winded, but just how it is.
I’ve never heard of poppers in this context before, only as a substitute for the word ‘buttons’, usually by elder folks; though I do believe that ‘Juice Box’ is the American term for cartons of juice.
I've called it a "Tetra Pak" since I was a child. It seems this term is actually the name of the company that developed the technology, and the package itself is called a "Tetra Brik".
Juice box does not exist in the Oxford Advanced Learner's Dictionary. These containers are called cartons in British English.
