A quality product made in the USA and are 5.1 mil thick, most are around the 3.5 mil mark many other suppliers don't mention the thickness of the foil bag for this very reason. 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.
Foil bags are usually used with oxygen absorbers, please see the related items below. 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.
The 300cc oxygen absorbers we sell work with this bag size, you will need one of the 300cc oxygen absorbers in each bag.
