When you're opening a large fizzy drink bottle for the first time, why does the wrapper around it start to sound "fizzly" and appear loosened?

Carbonation buildup causes the bottle to expand and when you open it the pressure is released. The noise you hear is the glue on the label detaching from the bottle along with the material shrinking back to it original form.

The wrapper is stretched around the bottle. Also when your open it, u let all the compressed gas out making the width get a bit smaller. Therefore the wrapper's grip on bottle loosens.

The carbonation in the liquid had outgassed and the plastic bottle was under pressure. When you took off the cap the pressure vented through the top and that relieved the pressure on the sides of the bottle. They relaxed down and the wrapped label was looser.

When you first open the soda bottle, you let out the CO2 pressure, and the bottle "relaxes", making the label fit less tightly.

the pressure in the bottle is lowered and thus the bottle is softer

because they pressurize it to retain the carbonation. When you open the bottle, it depressurizes.
