The processing methods include “water bath” and “acid or alkali bath” with different materials. However, the aluminum layer would be removed in the transparent area of the aluminum composite film through “partially transparent” processing. Only base film and heat sealing film are remaining so that the barrier property of the transparent area in the composite film would be reduced. If the content inside the package is sensitive to water and oxygen, the change of barrier property of the composite film would influence the quality of the products greatly and as a result, the shelf life would be decreased.
