This is because of the helium they use to blow them up. If you noticed if you blow it up with your mouth, it does not float.
Helium is much less dense for a given volume than air. The air pushes beneath the balloon and forces it upward. If it reaches a point high in the atmosphere where the air is the same density as the helium, it will stop rising. However, the pressure in the balloon will also force it to expand, so it will normally pop before it gets that high. Most latex balloons will pop, and most Mylar balloons will split open, somewhere around 2,000 to 5,000 feet in the air.

Will warming helium balloons make them float?
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
What makes balloons float when they are full of air but not float when they are deflated?
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
Why do big balloons with helium gas floats and buoyed up?
Helium is lighter than air, hence balloons filled with helium will float and rise up.

Why do you think hot-air balloons can rise into the air?
Hot-air balloons can rise up into the air because hot air is lighter, allowing it to float up into the sky.
