There is air pressure in that bag too
the mass of an object is the same, no matter where it is.
Tt makes the bag weaker by evaporating the plasticizers the stiffer material physically snaps into smaller pieces)or by breaking bonds in the polymer. Biodegradable bags exploit this by installing weaker bonds in the polymer (usually starch) that are more sensitive to light or biological attack.
Not if it is an artificial sponge.

it wouldn't make any affect, we think, and it would just stick to the plastic bag!
In heat the bag will decrease in tensile strength. In coldness it will have weaker overall structural integrity.
in the plastic bag first
