Is Aluminum Foil Raw Materials susceptible to environmental humidity and temperature?

Aluminum foil usually has a dense oxide layer on its surface to protect it from corrosion. However, when the ambient humidity is high, the foil may absorb moisture, causing the oxide layer to be damaged, which in turn causes corrosion. This corrosion not only affects the aesthetics of the foil, but may also reduce its mechanical and electrical properties.
In a high humidity environment, the surface of the foil may gradually darken and even develop small holes due to moisture erosion. These small holes will destroy the integrity of the foil, reduce its sealing and barrier properties, and thus affect its application effect. Humidity may also cause the foil to soften and deform. When the foil absorbs moisture, the interaction force between its molecules will change, causing the overall structure of the foil to become unstable, and then soften and deform. This will affect the processing performance of the foil and the quality of the final product.
Higher temperatures will accelerate the aging process of the foil, resulting in performance degradation. For example, the strength and toughness of the foil may decrease with increasing temperature, making it more susceptible to damage. A protective or functional coating is usually applied to the surface of the foil to improve its corrosion resistance, aesthetics or other properties. However, in high temperature environments, these coatings may fall off due to thermal expansion or chemical reactions, thus affecting the use of aluminum foil. Temperature changes may also cause thermal stress in aluminum foil, which in turn causes deformation. This deformation may affect the dimensional stability and shape accuracy of aluminum foil, thus affecting its performance in various applications.
In order to reduce the impact of ambient humidity and temperature on Aluminum Foil Raw Materialss, the following measures can be taken:
Store Aluminum Foil Raw Materialss in a dry environment with a relative humidity of 40% to 60%. Tools such as dehumidifiers, desiccants or sealed containers can be used to reduce ambient humidity.
Store Aluminum Foil Raw Materialss in an environment around room temperature (20~25℃). Avoid long-term exposure to high or low temperatures to reduce the impact of temperature on the performance of aluminum foil. Equipment such as air conditioners and heaters can be used to adjust the ambient temperature.
In a humid or polluted environment, using sealed containers to store Aluminum Foil Raw Materialss can prevent them from being eroded by the external environment. Sealed containers should have good sealing and moisture-proof properties to ensure long-term storage of Aluminum Foil Raw Materialss.
Regularly inspect and maintain the environment where Aluminum Foil Raw Materialss are stored to ensure that the ambient humidity and temperature are within an appropriate range. At the same time, regular inspections are carried out on Aluminum Foil Raw Materialss to promptly identify and address possible problems.
