The application of aluminum coating in food packaging is very extensive, mainly due to its excellent performance and diverse functions.

The following are some main applications of aluminum coating in food packaging:

1. Light blocking and UV protection: Aluminum coating has the function of blocking light and preventing UV radiation, which is particularly 

important for foods that need to avoid direct sunlight and UV radiation. By using aluminum coated packaging, the shelf life of food can be effectively extended, maintaining its freshness and taste.

2. Gas barrier: The aluminum coating has good barrier performance against gases, water vapor, etc. In food packaging, this can prevent 

adverse effects of external factors such as oxygen and moisture on the food, thereby maintaining the quality and stability of the food.

3. Aesthetics and upgrading: The aluminum coating has a metallic luster and good reflectivity, making the packaged food more beautiful and improving the product's level. 

This packaging material can also be treated with paint to form a colored film, further enhancing its decorative effect and attracting the attention of consumers.

4. Folding resistance and toughness: Aluminum plated film has excellent folding resistance and toughness, which makes it less prone to damage or cracking during food packaging, 

ensuring the integrity and safety of the packaging.

5. Environmental protection and sustainable development: Compared with traditional aluminum foil composite materials, aluminum coating can to some extent replace aluminum foil, 

reducing the burden on the environment. Meanwhile, with the continuous development of technology, the production process of aluminum coating also pays more attention to environmental 

protection and sustainable development.

Overall, the application of aluminum coating in food packaging has multiple advantages, not only improving the quality and grade of food, but also meeting the needs of environmental 

protection and sustainable development. In the future, with the continuous innovation of technology and the growth of market demand, the application of aluminum coating in the field of 

food packaging will be more extensive and in-depth.

In addition, different types of aluminum coatings also have specific applications in food packaging. For example, PET aluminum coating is mainly used for various food packaging, 

such as chocolate, coffee, biscuits, etc., which can effectively isolate the invasion of oxygen, water, and light. CPP aluminum coating is commonly used in fields such as hot filling, cooking bags,

sterile packaging, etc. It has excellent heat resistance, acid resistance, alkali resistance, oil resistance, and is safe to come into contact with food. These characteristics make CPP aluminum coating

the preferred material in the packaging field of bread products or laminated materials.
