由于被包装的物品与外界的光、湿、气等充分隔绝，从而使包装物受到了完好的保护。尤其是对蒸煮食品的包装，使用这种复合铝箔的材料，至少可以保证食物一年以上不变质。而且，加热和开包都很方便，深受消费者的欢迎。一般包装铝箔厚度0.03mm-0.1mm之间。
Due to the full isolation of the packaged goods from the outside light, humidity and gas, the packaged goods are well protected. Especially for the packaging of cooked food, the use of this composite aluminum foil material can ensure that food does not deteriorate for at least one year. Moreover, heating and unpacking are very convenient and popular with consumers. Generally, the thickness of aluminium foil is between 0.03mm and 0.1mm.

Characteristics of Aluminum Foil
铝箔具有清洁，卫生及闪闪发亮的外表，它可与许多其它包装材料做成集成包装材料，而且铝箔表面印刷效果比其它材料都好，除此之外铝箔还有以下几个特性：
Aluminum foil has a clean, hygienic and shiny appearance. It can be integrated with many other packaging materials, and the printing effect of the surface of aluminum foil is better than that of other materials. In addition, aluminum foil has the following characteristics:
（1）铝箔表面极为干净、卫生、任何细菌或微生物都不能在其表面生长。
(1) The surface of aluminium foil is extremely clean, sanitary, and no bacteria or microorganisms can grow on it.

(7) Aluminum foil has good plasticity, so it can be used to package products of various shapes. It can also create containers of various shapes at will.
（8）铝箔的硬度大，张力强度也大，但是其撕裂强度小，所以极易撕破。
(8) Aluminum foil has high hardness and tension strength, but its tearing strength is small, so it is easy to tear.
（9）铝箔本身无法加热封密，必须在其表面涂抹可热性的材料，如pe才能热封闭。
(9) Aluminum foil itself can not be heated and sealed, so it must be coated with heat-resistant materials, such as PE, in order to be heat-sealed.
（10）铝箔与其他重金属或重金属类接触时，可能会有不良反应。
(10) Aluminum foil may have adverse reactions when it comes into contact with other heavy metals or heavy metals.
