• 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

• Food-grade and BPA free - Safe for food contact
  

To seal these bags use a household clothes iron on the high setting, with no steam or hair crimper.

8 mil thick (204um), 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 match this bag size and you will need one oxygen absorber in each bag.
