Canned Soft Drink Lose Fizz Slower?

Fizzy drinks are great but when the fizz is almost gone, the experience is much less enjoyable.

Take coca cola as example, I notice that the 1.5L bottle tend to lose a lot of fizz just over one night, but for canned version even without sealing it and leaving it overnight in the fridge, the fizz is still almost the same.

I'm guessing that aluminium seems to be able to "trap" gas better than plastic bottle.
