There are many kinds of packaging bags, and it is easy to confuse aluminum foil bags with aluminum-coated bags when ordering packaging bags. Xfy-Packaging bags , which specializes in the production of clothing bags, aluminum foil bags, aluminum-plated bags, food packaging bags, cosmetic packaging bags, and hardware and electronic packaging bags, will explain to you how to distinguish between aluminum foil bags and aluminum-plated bags today.

Features of aluminum foil bags:

The surface of the aluminum foil bag is very clean and hygienic, no microorganisms can grow on the surface, and it can be in direct contact 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 beverages, coffee, etc. It is a very good packaging material. No matter at high temperature or low temperature, the aluminum foil bag will not be soaked. Air and moisture permeability are low, which can well protect the interior products. Aluminum foil itself is non-volatile, and it and the packaged food will not dry or shrink. The tasteless and odorless packaging material will not make the packaged food have any peculiar smell. It has stable performance, can be stored in various high and low temperature environments, and has certain corrosion resistance.

Aluminum foil bags are coated with a thin layer of aluminum powder on the plastic film to play a decorative role. In terms of performance, its cooling effect is better than that of pure aluminum bags, which are completely protected from light, and aluminum-plated bags have a shading effect. In terms of materials, the pure aluminum bag is pure aluminum with high purity and is a soft material; the aluminum-plated 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 cooked food, meat and other products, while aluminum-coated bags are suitable for tea, powder, etc. In terms of cost, the unit price of pure aluminum bags is higher than that of aluminum-plated bags.

So how do we distinguish them? Let me teach you a few simple methods.

1. Watching: Because the brightness of aluminum foil is not as bright as aluminum plating. Aluminum-coated bags can show people's shadows. You can block the mouth of the bag and see the inside of the bag through strong light. The inside of the aluminum foil bag is opaque, and the light-transmitting bag is the aluminum-coated bag.

2. Hand feeling: the hand feeling of the aluminum foil bag is thick, hard and heavy, and the hand feeling of the aluminum-plated bag is lighter and softer than the aluminum foil bag.

3. Folding: Aluminum foil bags are easy to fold to produce dead folds and dead marks, while the other one will not fold to produce dead folds and dead marks.

I believe that after carefully reading the difference between the aluminum foil bag and the aluminum-plated bag above, you will be able to distinguish them.
