IME to keep moisture & gases etc reliably in/out of film based
containers you need a "layer" of (usually) Alu foil in the film's
construction.
This "real deal" (think astronaut food packs) is somewhat more
expensive & a little harder to work with due to its rigidity.
The shiny metallised foils you mention are no good long term but they
do look flash for the marketeers.
Kids helium balloons - the day/few days *after* the party - are
usually flacid & don't float only having air left in them as the
helium has escaped through the pores in the material.
