Fabricated from five layers of very distinct materials to achieve low permeability numbers. These bags are used when the sample must be kept in the bag for long periods of time. However, one must adjust for the inner layer of polyethylene which might affect the stored sample. These bags are tough, economical and provide light blocking capabilities.
Inert 5 Multi-Layer Bags are ideal for containing low molecular weight gases. The 2 layers of aluminum film plus 3 other distinct layers provide a great barrier to gases permeating through the walls of the bag. Samples can be shipped without worry of losing sample components.
