Bubble Wrap would be a poor comparison, if even comparable at all.

I went to the dynamat link but it does not show a cross section of the material.
Someone mentioned that it is of a bubble wrap nature.
If it is of a bubble wrap type of material then the bubbles will quickly burst over a period of time as feet and other objects scrub, press or drop on it.
Anything of a bubble wrap nature does not sound like a good idea to me LONG TERM.
Dynamat is used to soften or deaden noises. The example they use is to take a bell that you would see on a clerk's desk. Then take a second bell and attach a small piece of the dynamat to the outside. The noise suppression is quite noticeable.
When used in cars, it helps to keep road, engine, or environment noise down. But it will not eliminate it. Noise from windows and door openings will allow sound to enter the vehicle.
With car audio, many times, people will just install the material directly behind or underneath speakers to help increase the quality of sound played. (less background noise interferring with the music)
To do it correctly, the entire surface needs to be covered.
From my experience with installing the dynamat, it is a little hard to work with due to the thickness of the material, (If I had to guess, 1/8" to 3/16",) and requires a roller and a lot of patience. But the difference is noticeable. However, to install completely in a car would be pricey. I have seen people have rhino or linex installed instead of dynamat due to speed and cost.
With respect to if the metal tape wrap at home depot or lowes is comparable, that would be up for debate. I believe the thickness and density of the dynamat is greater than that of the home improvement materials, but would need to perform a science experiment to be sure.
Hope this helps.
