由于被包裝的物品與外界的光、濕、氣等充分隔絕，從而使包裝物受到了完好的保護。尤其是對蒸煮食品的包裝，使用這種復合鋁箔的材料，至少可以保證食物一年以上不變質(zhì)。而且，加熱和開包都很方便，深受消費者的歡迎。一般包裝鋁箔厚度0.03mm-0.1mm之間。
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.
鋁箔的特點
Characteristics of Aluminum Foil
鋁箔具有清潔，衛(wèi)生及閃閃發(fā)亮的外表，它可與許多其它包裝材料做成集成包裝材料，而且鋁箔表面印刷效果比其它材料都好，除此之外鋁箔還有以下幾個特性：
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）鋁箔表面極為干凈、衛(wèi)生、任何細菌或微生物都不能在其表面生長。
(1) The surface of aluminium foil is extremely clean, sanitary, and no bacteria or microorganisms can grow on it.
（2）鋁箔是一種無毒性的包裝材料，它可與食品直接接觸而沒有任何可危害人體健康的憂患。

(2) Aluminum foil is a non-toxic packaging material, which can be directly contacted with food without any health hazards.
（3）鋁箔為一種無味無臭的包裝材料，不會使包裝的食品有任何異味。
(3) Aluminum foil is a odorless and odorless packaging material, which will not make the packaged food have any odor.
（4）若鋁箔本身并無揮發(fā)性，它本身以及包裝了的食品絕不會干燥或收縮。
(4) If the foil itself is not volatile, it and the packaged food will never dry or shrink.
（5）無論在高溫或者在低溫下，鋁箔都不會有油脂滲透的現(xiàn)象發(fā)生。
(5) Whether at high temperature or low temperature, there is no oil infiltration in aluminum foil.
（6）鋁箔為一種不透光的包裝材料，因此對于陽光線照射的產(chǎn)品，如人造奶油等是一種很好的包裝材料。
(6) Aluminum foil is an opaque packaging material, so it is a good packaging material for sunshine products, such as margarine.
（7）鋁箔具有很好的可塑性，所以可用于包裝各種形狀的產(chǎn)品。也可任意造成各種形狀容器。
(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）鋁箔的硬度大，張力強度也大，但是其撕裂強度小，所以極易撕破。
(8) Aluminum foil has high hardness and tension strength, but its tearing strength is small, so it is easy to tear.
（9）鋁箔本身無法加熱封密，必須在其表面涂抹可熱性的材料，如pe才能熱封閉。
(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）鋁箔與其他重金屬或重金屬類接觸時，可能會有不良反應。
(10) Aluminum foil may have adverse reactions when it comes into contact with other heavy metals or heavy metals.
