Aluminum foil is a soft metal film with many advantages, such as moisture-proof, air-tight, light-shielding, abrasion resistance, fragrance retention, non-toxic and odorless. It also has a silvery white luster and is easy to process into various beautiful patterns and patterns. After being combined with plastic and paper, the shielding performance of aluminum foil is integrated with the strength of paper and the heat sealing of plastic, improving the shielding performance against water vapor, air, ultraviolet rays and bacteria. This greatly broadens the application market of aluminum foil.
Aluminum foil for packaging usually uses 1 series, 3 series and 8 series products, mainly including models 1060, 1100, 3003, 8011, 8021, etc. Commonly used statuses are H14, H16, H18, etc.
Advantages of aluminum foil as packaging material:
1. Aluminum foil has high barrier properties to water, water vapor, light and aroma, and is not affected by the environment and temperature. Therefore, it is usually used in perfume packaging, moisture-proof packaging, etc. to prevent moisture absorption, oxidation, and volatilization of the packaging contents. Especially suitable for sterilization packaging of high-temperature cooking food, such as container aluminum foil. Milk packaging aluminum foil.
2. An oxide film naturally forms on the surface of aluminum foil. The formation of oxide film can further prevent the continuation of oxidation. Therefore, when the packaging contains high acidity or alkalinity, a protective layer or PE is usually added to the surface of the aluminum foil roll to improve its corrosion resistance.
3. Aluminum foil has stable performance under high and low temperatures, strong heat resistance (121℃) and low temperature resistance (-50℃), good shape under high and low temperatures, and thermal conductivity as high as 55%. Therefore, it can be used for high-temperature cooking or other heat treatments as well as frozen packaging.
4. Aluminum foil has good light-shielding properties, its reflectivity can reach more than 95%, and its appearance is silver-white metallic luster. Surface printing decoration can show good packaging and decoration effects, and is often used in cosmetic bottle cap aluminum plates.
5. Aluminum foil is environmentally friendly and recyclable.
