Aluminum foil is a material that is directly pressed into thin sheets by metal aluminum. It has soft texture and good ductility. It is widely used in food packaging, pharmaceutical packaging, cable foil, air-conditioning foil, battery foil, and building insulation. Especially in the packaging industry the application is very common.
Aluminum foil for packaging is made of electrolytic aluminum with a purity of 99.0%-99.7%, which is obtained through multiple calendering. Commonly used alloys are 1060 aluminum foil, 1100, 3003, 8011, 8021 aluminum foil, etc. This kind of packaging is not only moisture-proof, air-tight, and light-shielding, but also has the advantages of fragrance retention, non-toxic and tasteless, etc. It can be customized with different specifications and styles of packaging bags, and can be made into flat bags, three-dimensional bags, organ bags and other styles. , such advantages are unmatched by any other existing packaging materials. Below, I will give you a detailed introduction to the advantages and disadvantages of aluminum foil packaging.
First, the advantages of aluminum foil packaging
1. Light weight, good extensibility and thin thickness;
2. Good shading performance, the reflectivity can reach 95%;
3. Strong barrier property, which can effectively protect food and avoid bacterial contamination;
4. Moisture-proof, air-tight, and fragrance-preserving, which can prevent moisture absorption, oxidation and volatilization of the packaging contents, and its moisture and oxygen barrier properties.
5. It has a shiny metallic luster and is highly decorative;
6. Aluminum foil is non-toxic, tasteless and odorless;
7. Aluminum foil is easy to process and can be compounded with various plastic films and paper.
Second, the disadvantages of aluminum foil packaging
1. Aluminum foil has low strength and is easy to tear, so it cannot be used alone for packaging products.
2. It is easy to break when folded, resulting in holes and not resistant to acid and alkali.
