In the field of electronic product packaging, moisture-proof is a crucial indicator, because a humid environment may cause serious damage to electronic products, such as short circuits and corrosion. Lamination adhesives for PET aluminum coated film has been widely used in electronic product packaging due to its excellent moisture-proof performance, and its moisture-proof function is mainly reflected in the following aspects.
Dense aluminum coating blocks water vapor
Lamination adhesives for PET aluminum coated film is a dense aluminum layer formed on the surface of PET film through a vacuum aluminum coating process. This aluminum layer is like a solid barrier that can effectively block the penetration of water vapor. Aluminum itself has good barrier properties, which can prevent water vapor in the outside air from entering the interior of the package. Moreover, the continuity and uniformity of the aluminum coating further enhance its moisture-proof effect. Even in a high humidity environment, it is difficult for water vapor to pass through this dense aluminum layer to contact electronic products, thus providing reliable moisture-proof protection for electronic products.
Synergistic effect with PET substrate
PET film itself has certain moisture-proof properties, and it has low moisture permeability. When combined with the aluminum layer, the two work together to greatly improve the overall moisture-proof ability. The PET substrate provides stable support for the aluminum layer, ensuring the integrity and stability of the aluminum layer. At the same time, the flexibility of the PET film also enables Lamination adhesives for PET aluminum coated film to adapt to the packaging needs of electronic products of different shapes. During the packaging process, Lamination adhesives for PET aluminum coated film can fit electronic products tightly, reduce the gaps for water vapor to enter, and further enhance the moisture-proof effect.
Application in sealed packaging
In the packaging of electronic products, sealed packaging is often used, and Lamination adhesives for PET aluminum coated film is very suitable for this packaging form. It can form a sealed packaging bag through processes such as heat sealing, and completely wrap the electronic products in it. In a sealed environment, the moisture-proof function of Lamination adhesives for PET aluminum coated film is maximized. External water vapor cannot enter the interior of the packaging bag, and the dry environment inside the packaging bag is maintained, thus creating a good storage and transportation condition for electronic products. Even during long-term transportation and storage, it can effectively prevent electronic products from being damaged by moisture.
Adaptability to humidity changes
Lamination adhesives for PET aluminum coated film has good stability and can adapt to different humidity changes. In an environment with high humidity, it can maintain good moisture-proof performance and prevent water vapor penetration; in an environment with low humidity, it will not crack or delaminate due to drying, and can still maintain a complete moisture-proof barrier. This adaptability to humidity changes enables Lamination adhesives for PET aluminum coated film to provide reliable moisture-proof protection for electronic products under various climatic conditions.
Lamination adhesives for PET aluminum coated film, with its dense aluminum coating, synergy with PET substrate, application in sealed packaging and adaptability to humidity changes, has demonstrated excellent moisture-proof function in electronic product packaging, providing a strong guarantee for the safe transportation and storage of electronic products.
