Aluminum foil bag packaging usually refers to the aluminum plastic composite
Vacuum packing bag. Most of these products are used for the packaging of tea,
food packaging, and pharmaceutical intermediates. It has the characteristics of
moisture-proof, light proof, and vacuum pumping. Adopting a three-layer or
four-layer composite structure, it has good water and oxygen isolation
functions. Unlimited, packaging bags of different specifications and styles can
be customized, and can be made into various styles such as flat bags,
three-dimensional bags, organ bags, zipper bags, etc. The product must undergo
GB and ASTM standards testing, meet environmental requirements (third-party
testing reports can be provided), and comply with the most stringent
environmental standards for packaging materials in the European Union and North
America.
Aluminum foil bags can also be divided into pure aluminum bags and aluminum
plated bags. So how can we distinguish between aluminum plated bags and pure
aluminum bags in daily life? To summarize, there are several points:
1、 From a material perspective, pure aluminum bags are pure aluminum with
high purity and belong to soft materials; Aluminum plated bags are made of
brittle materials mixed with composite materials.
2、 In terms of cost, the price of pure aluminum bags is higher than that of
aluminum plated bags.
3、 In terms of performance, pure aluminum bags have better moisture-proof and
cooling effects than aluminum plated bags. Pure aluminum bags completely avoid
light, while aluminum plated bags have a shading effect.
4、 In terms of usage, pure aluminum bags are more suitable for vacuuming,
such as filling cooked food, meat, and other products, while aluminum plated
bags are suitable for filling tea leaves, powders, electronic components, and so
on.
5、 When facing the light or sunlight inside the bag, what can be seen through
the bag is aluminum foil, while what cannot be seen is pure aluminum foil.
