Does that also apply to those vacuum-sealed bags or will these help keep it fresh?
Polyethylene plastic bags such as baggies or zip-locs have an electrical charge which attracts glands. If you look at the surface of a used bag you will notice that it is covered with glands that have bonded with the plastic. Even scraping the material with a sharp surface such as a knife or razor blade will not remove them. These glands hold THC, the active ingredient in grass. When these glands transfer from the vegetative material to the bag, the potency of the grass is reduced.
Glass, metals and thermally-sealed plastic don’t carry an electrical charge so they can be used to store marijuana without affecting its quality.
