Aluminum foil has a clean, hygienic and shiny appearance. It can be made into integrated packaging materials with many other packaging materials, and the surface printing effect of aluminum foil is better than other materials. In addition, aluminum foil has the following characteristics: 

(1 ) The surface of aluminum foil is extremely clean and hygienic, and no bacteria or microorganisms can grow on its surface. 

(2) Aluminum foil is a non-toxic packaging material that can be in direct contact with food without any danger to human health. 

(3) Aluminum foil is a tasteless and odorless packaging material that will not cause any odor to the packaged food. 

(4) If the aluminum foil itself is not volatile, it and the packaged food will never dry or shrink. (5) No matter whether it is at high temperature or low temperature, there will be no grease penetration in the aluminum foil. 

(6) Aluminum foil is an opaque packaging material, so it is a good packaging material for products exposed to sunlight, such as margarine.

 (7) Aluminum foil has good plasticity, so it can be used to package products of various shapes. Containers of various shapes can also be made at will.

 (8) Aluminum foil has high hardness and high tensile strength, but its tear strength is low, so it is easy to tear. 

(9) Aluminum foil itself cannot be heat-sealed. It must be coated with a heatable material, such as PE, on its surface to achieve heat sealing.

 (10) Adverse reactions may occur when aluminum foil comes into contact with other heavy metals or heavy metals.
