FR-2175B is a foil barrier material used where very low oxygen and moisture levels are required. It is silver in color with red Mil Spec printing. It is used extensively in military applications where a cost-effective, strong, high barrier material is required. This FDA approved material is also vailable without the Mil Spec and is therefore unprinted (FFP500).
