This extra thickness is important as this offers extra protection from the UV (ultra-violet) in sunlight and also from oxygen penetration for the air around, plus are very hard to puncture accidentally. These foil bags are multilayered and have a food safe inner.

These remove the oxygen from inside the bag, preserving the shelf life of the food stuffs above for many years, usually up to 10 years. For camping or hiking trips or similar, oxygen absorbers are not really needed.
