Question how are these weights different?

Correct me if I’m wrong but all liquid weights the same if both liquids are the same ml?

ml is volume. Weight also considers density. Assuming the volume in the cans is the same then either the cans are different materials or the liquid is different density.

Tango and Pepsi are from the same parent company so packing very unlikely to be much different

I believe most of these drinks companies only make the syrup and then have distributors in the various regions who will mix it and create the final product. Not sure if the distributors are third party only or a mix.

Both drinks are mostly water. The density of the drinks are probably quite close.

Somethings to note, the actual volume of liquid in each can, will vary. I don't know how much it can legally vary by but a 700g difference is about 30 ml extra fluid per can. Less if you include variation in can weight.

So it is possible that Tango elects to put the worst case weight on the packaging while Pepsi elects to put the nominal weight.

I would imagine it's down to the difference between steel and aluminium cans. You could test it with a magnet, it should stick to a steel can depending on the specific type of steel used. Steel cans also tend to be tougher to crush.
 
If it were water then you'd expect 24x330ml to be around 8kg (plus packaging weight).

9kg seems a lot for just different density of liquid, but they could just be rounding up from say 8.5kg.

Tin. Hence tin cans or tinnies.

No, they are plastic lined. Its a very thin lining but its there.

Tin cans refers to steel lined food cans generally.

Coatings​

There’s always a thin plastic layer (coating) inside drink cans to protect the food or liquid and to protect the cans from corrosion. Every soda contains phosphoric and citric acid and it’s thus necessary to add a hidden liner inside the can to prevent the beverage from reacting with the metal.

Coatings contain different additives, e.g. agents to increase surface slipping as well as abrasion and scratch resistance of can coatings, lubricants, anti-foaming agents, adhesives, scavengers for hydrochloric acids, and pigments.

I've always wondered why some cans are aluminium and some steel.

What are the pro and cons of each, and if you owned a huge fizzy beverage enterprise what would you go with?

I think aluminium in easier to work with in this instance. It is also lighter so transport cost are reduced. But it is more expensive per kg than steel.
