如何分别铝箔袋和镀铝袋?

来源:http://www.jingmeisuliao.com/ 日期:2023-01-19

铝箔的特点:铝箔表面很干净、卫生、任何微生物都不能在其表面生长,可与食品直接接触而没有任何可危害人体健康的忧患。作为不透光的包装材料,对于阳光线照射的产品有很好的保护,如油性产品,固体饮料,咖啡等是一种很好的包装材料,无论在高温或者在低温下,铝箔都不会有浸透的现象发生。空气,水分透过率低,能很好地保护内装产品。铝箔本身并无挥发性,它本身以及包装了的食品不会干燥或收缩,无味无臭的包装材料,不会使包装的食品有任何异味。性能稳定,能适应各种高低温环境存放,有一定的耐腐蚀性。

Features of aluminum foil: the surface of aluminum foil is clean and sanitary, and no microorganism can grow on it. It can be directly contacted with food without any worries that may endanger human health. As an opaque packaging material, it has good protection for products exposed to sunlight, such as oily products, solid drinks, coffee, etc. It is a good packaging material. No matter at high temperature or low temperature, aluminum foil will not be soaked. The air and water permeability are low, which can protect the inner products well. The aluminum foil itself is not volatile. It and the packaged food will not dry or shrink. The tasteless and odorless packaging materials will not make the packaged food have any peculiar smell. Stable performance, suitable for storage in various high and low temperature environments, with certain corrosion resistance.
为什么要在包装袋内加入一层纯铝箔呢?铝箔也广泛用于隔离层,热交换,和用作导电体。通常,用作纸包饮品包装、食品包装袋里的铝箔厚度仅仅为6.5微米。这薄薄的铝层可以防水、保持鲜味、防止有害微生物和防污。具有不透明,呈银白色,有反光泽,良好的阻隔性、耐高/低温、耐油性、热封性、遮旋光性、保香性、无异味、柔软性等特点。
Why add a layer of pure aluminum foil into the packaging bag? Aluminum foil is also widely used as insulating layer, heat exchange, and conductor. Generally, the thickness of aluminum foil used in paper packaging of drinks and food packaging bags is only 6.5 microns. This thin aluminum layer can be waterproof, keep fresh, prevent harmful microorganisms and prevent pollution. It is opaque, silvery white, anti-gloss, good barrier property, high/low temperature resistance, oil resistance, heat sealing property, light shielding property, fragrance retention property, no odor, softness and other characteristics.
镀铝包装袋,是在塑料膜上镀上一层薄薄的铝粉,起到装饰作用。镀铝包装袋也叫铝塑包装袋。铝箔包装袋,顾名思义是内部结构含有铝箔(纯铝)的一种包装袋,因内层结构含有纯铝箔,简称为铝箔包装袋,也叫纯铝袋,铝铂袋。其实铝箔袋是有多种塑料薄膜和99.9%的纯铝层复合后,通过制袋成型机械封口裁切而成的袋子。
The aluminized packaging bag is coated with a thin layer of aluminum powder on the plastic film to play a decorative role. Aluminized packaging bags are also called aluminum-plastic packaging bags. The aluminum foil packaging bag, as the name implies, is a kind of packaging bag with aluminum foil (pure aluminum) in the internal structure. Because the internal structure contains pure aluminum foil, it is called aluminum foil packaging bag for short, also called pure aluminum bag, aluminum platinum bag. In fact, the aluminum foil bag is a bag made of a variety of plastic films and 99.9% pure aluminum layer, which is cut through the mechanical sealing of the bag forming machine.

从性能上说,降温效果比镀铝袋好,纯铝袋完全避光,镀铝袋是遮光效果。从材料上说,纯铝袋是纯铝,纯度高,属软性材料;镀铝袋掺有复合材料,是脆性材料。从使用上来说,纯铝袋更适合抽真空,如装熟食、肉类等产品,而镀铝袋适合装茶叶、粉末等。从成本上说,纯铝袋的单价比镀铝袋的高。把袋子里面对着灯光或者太阳光照,能透过袋子看见光的就是镀铝箔,看不见的就是纯铝箔。
In terms of performance, the cooling effect is better than the aluminized bag. The pure aluminum bag is completely dark, and the aluminized bag is the shading effect. In terms of material, the pure aluminum bag is pure aluminum with high purity and belongs to soft material; The aluminized bag is mixed with composite materials and is a brittle material. In terms of use, pure aluminum bags are more suitable for vacuuming, such as filling cooked food, meat and other products, while aluminized bags are suitable for filling tea, powder, etc. In terms of cost, the unit price of pure aluminum bags is higher than that of aluminized bags. When the inside of the bag is exposed to light or sunlight, the light that can be seen through the bag is aluminum foil, and the invisible is pure aluminum foil.
在外观上,两者的区别不大。同样一个产品,放在镀铝包装内可能一个月会出现水分丢失,微生物大量滋生的情况。而放在铝箔包装袋内,可能半年以后才会出现类似的情况。为了保证内装产品的品质,很多包装进行了真空处理。进行真空之后,内部氧气减少,微生物没有生长的环境,从而达到保护产品的作用。
In terms of appearance, there is little difference between the two. The same product, placed in aluminized packaging, may have moisture loss and a large number of microorganisms in a month. If it is placed in the aluminum foil packaging bag, the similar situation may not occur until half a year later. In order to ensure the quality of the products inside, many packages have been vacuum treated. After vacuum, the internal oxygen is reduced, and there is no environment for microorganism growth, so as to protect the product.
其次,铝箔包装袋稳定性很好,一般不会受外部环境的影响发生变质的情况。而从功能作用是,两者相差甚远。首先,铝箔袋由于夹层是纯铝箔,其防潮,避光,防水,放氧化作用要远远强于镀铝包装袋。
Secondly, the aluminum foil packaging bag has good stability and generally will not deteriorate due to the influence of external environment. In terms of function, the two are far from each other. First of all, because the interlayer of the aluminum foil bag is pure aluminum foil, its moisture-proof, light-proof, water-proof and oxidation-resistant effect is far stronger than that of the aluminized packaging bag.
经久耐用是铝箔包装袋的代言词。两种包装袋皆可印刷图案,铝箔袋的手感较软,镀铝袋的手感较硬。因此铝箔袋更适合用于食品,药品,化工产品,一些电子配件,机械配件由于密封需要也经常会用到铝箔袋。而镀铝袋则多用于快速品,这并不是说镀铝包装袋不好,恰恰证明镀铝包装的性价比很高。
Durability is the pronoun of aluminum foil packaging bag. Both kinds of packaging bags can be printed with patterns. The aluminum foil bag has a soft feel and the aluminized bag has a hard feel. Therefore, aluminum foil bags are more suitable for food, medicine, chemical products, some electronic parts, and mechanical parts. Because of the need for sealing, aluminum foil bags are often used. The aluminized bags are mostly used for fast goods. This is not to say that the aluminized bags are not good, but just to prove that the aluminized bags are cost-effective.
