• Lightproof - Due to the real layer of aluminium and not the cheaper sprayed on metal colour version (metallised) which shows pinholes easily
  
  
• Smellproof - Once sealed smells cannot escape, this is due to extra thickness of our premium bags
  
  
• Moistureproof - Once sealed moisture from the air or even ground cannot enter as air tight seal is made, due to premium quality of the bag
  
  
• Boil in the Bag / Freezer Proof - Suitable for boil in the bag, due to special glue used,  for up to 30 minutes and down to - 60 degrees Celsius

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.
