In the past, people liked to use wax paper to package ice cream, which is more high-grade and can prevent moisture. But the disadvantage is that the wrapping paper tends to spring back when it is twisted. With the development of the times, aluminum for food packing became popular and was used in ice cream packaging. Due to its thinness and strong plasticity, aluminum foil avoids the disadvantage of easy rebound when twisted.
Aluminum foil is a soft metal film, which not only has the advantages of moisture-proof, air-tight, light-shielding, abrasion-resistant non-toxic and tasteless, but also because of its elegant silver-white luster. It is easy to process beautiful patterns and colors, so it is more likely to be favored by people.
Especially after aluminum foil is compounded with plastic and paper, the shielding property of aluminum foil is integrated with the strength of paper and the heat sealing property of plastic, which further improves the shielding performance against water vapor, air, ultraviolet rays and bacteria, etc., and broaden the application market of aluminum foil.
Since the packaged items are fully isolated from the light, moisture, and gas of the outside world, the packaged items are well protected. Especially for the packaging of cooked food, the use of this composite aluminum foil material can at least ensure that the food will not deteriorate for more than one year.
Aluminum foil has a clean, hygienic and shiny appearance. It can be made into an integrated packaging material with many other packaging materials, and the printing effect on the surface of aluminum foil is better than other materials. In addition, aluminum foil has the following characteristics:
1. Alu foil packaging can be in direct contact with food without any health hazards.
2. The surface of the aluminum foil is extremely clean and hygienic, and no bacteria or microorganisms can grow on the surface.
3. Aluminum foil is an odorless packaging material, which will not make the packaged food have any peculiar smell.
4. Alu foil packaging is an opaque packaging material, so aluminum foil packaging bags are a good choice for foods that need to be protected from light.
