What Are the Properties of Aluminum Foil
What are the properties of aluminum foil ? We should know the performance of aluminium foil first. The properties of aluminum foil determines the uses of aluminum foil, and the performance shows the the properties of aluminum foil. The properties and performance of aluminum foil are: 1, Thickness Thickness is one of the most basic and very important physical properties of aluminum foil. The thickness of aluminum foil has a certain relationship with its barrier properties. As the thickness of aluminum foil increases, its transmittance to oxygen, water vapor, light, etc. gradually decreases, and accordingly, its barrier properties are also higher. The thickness of aluminum foil used in composite flexible packaging is usually between 7 and 9 microns. In practical applications, aluminum foil of suitable thickness should be selected according to different contents and different performance requirements, otherwise it will n...
