The food packaging aluminum foil are mainly 1xxx, 3xxx and 8xxx aluminum foil, including 1060, 1100, 3003, 8011, 8021, etc. According to the needs of the packaged food, the degree of softness and hardness of the alloy is selected, that is, the aluminum alloy tempers. The commonly used states are H14, H16 and H18.
Aluminum foil packaging is made of pure aluminum with a purity of more than 99.5% by rolling, and the thickness is between 0.005 and 0.2mm. It is light and shiny, has strong reflective ability, and can be used as heat-proof and insulating packaging. It is convenient for printing, gluing, varnishing, coloring, embossing, printing, etc. Its biggest disadvantage is that it is not resistant to acid and strong alkali and has low tear resistance.
Many groceries are easily damaged by sunlight, which can damage their appearance and deteriorate their taste. Aluminum foil solves this problem in the best possible way, which is why it is often considered the ideal core packaging material for dairy products, pastries and beverages. For example, milk powder in sealed packages made of laminated foil has a shelf life of 2 years.
The heat dissipation speed of aluminum foil is also very fast, which is suitable for sterilization (autoclaving) and heat sealing process. For container packaging and flexible packaging, aluminum foil can minimize the heat sealing time and make the temperature gradient uniform, thus protecting the packaged products quality and save energy. For food packaged in aluminum foil, it can be cooked, heated or reheated in a light-wave oven, the grill block of a microwave oven or a double steamer.
In foreign countries, aluminum foil packaging is mostly used for catering, baking food packaging, utensils, etc. Aluminum foil products have entered the lives of ordinary people in many countries. Because it is very convenient and mostly "disposable", it is widely used in kitchen supplies, catering, or baking products.
