Aluminum Barrier Foil protects any product from deterioration due to moisture, oxygen ingress, U.V. light, temperature extremes, odors and much more.
The performance of Aluminum Barrier Laminates is determined by their Moisture Vapor Transmission rate (W.V.T.R.), which at <0.01g/100inches²/24hr for the laminate itself and less than <0.05g/100inches²/24hr for converted laminates, is lower than any known flexible packaging material.
To compare Polyethylene, with a thickness of 25um, allowing water vapor and aggressive gasses to diffuse at a rate of up to 4g/100inches²/24hr, which is 80 times faster!
Within a hermetically sealed Aluminum Barrier Bag, a calculated amount of desiccant can be added to the bag to ensure that the relative humidity (RH) remains below 40% – the starting point for corrosion.
