The thicker the aluminum foil material will be better?
Wrong. Aluminum foil has excellent barrier properties as a metal material. It is often assumed that the thicker the packaging material, the better the product protection, but the case of aluminum foil composites is different. If there are no cracks or pinholes in the foil layer itself, it doesn't matter how thick or thin it is. Because aluminum foil is a metallic material, the natural dense nature of the material determines its excellent barrier properties.
