What Are the Advantages of Aluminum Foil Bags?

Material.

Glossy aluminum foil composite (PET/AL/PE), Matte aluminum foil composite (MPET/AL/PE).  

Characteristics of aluminum foil.

The surface of aluminum foil is so clean and hygienic that no microorganism can grow on its surface, and it can come into direct contact with food without any worry of harming human health. As an opaque packaging material, it has good protection for products exposed to sunlight, such as oily products, solid drinks, coffee, etc. Whether high or low temperature, aluminum foil will not get wet. With low permeability and water permeability, it can protect the product interior well. Aluminum foil itself does not volatilize, it will not dry or shrink itself and the packaged food, and the packaging material is tasteless and odorless, which will not make the packaged food have any odor. It has stable performance and can adapt to various high and low temperature environments for storage.

Why put a layer of pure aluminum foil in the bag?

Aluminum foil is also widely used as an insulating layer, heat exchanger and conductor.

Typically, aluminum foil used for beverage packaging and food packaging is only 6.5 microns thick. The thin aluminum layer provides water resistance, maintains freshness, and protects against harmful microorganisms and contamination. It is opaque, silver-white, luster resistant, good barrier, high and low temperature resistant, oil resistant, heat sealable, light blocking, fragrance retention, odorless, and soft.  

Aluminized bag, is coated with a thin layer of aluminum powder on the plastic film to play a decorative role.

Aluminum foil bag, as the name implies, is a kind of bag whose internal structure contains aluminum foil (pure aluminum), because the internal structure contains pure aluminum foil, referred to as aluminum platinum bag. In fact, aluminum foil bags are made of a variety of plastic films and 99.9% pure aluminum layer compound, sealed and cut bags by bag-making machine.

In terms of performance

Heat dissipation effect is better than the aluminum bag, pure aluminum bag completely avoid light, aluminum bag is shading effect.

From the material point of view

Pure aluminum bag is pure aluminum, high purity, is a soft material; mixed with composite material aluminized bag is brittle material.

In terms of use

Pure aluminum bags are more suitable for dust absorption, such as loading cooked food, meat and other products, while aluminum bags are suitable for loading tea, powder, etc.

In terms of cost

The unit price of pure aluminum bags is higher than that of aluminum-plated bags. Place the bag in front of the light or sun. If you can see the light through the bag, it is aluminum foil. If you can't see it, it is pure aluminum foil.  

Appearance

Visually, there is not much difference between the two. The same product, placed in an aluminized package for a month may show water loss and a lot of microbial growth. And put in the aluminum foil bag, a similar situation may occur after six months. In order to ensure the quality of the product inside, many packages are vacuumed. After vacuuming, the internal oxygen is reduced and there is no environment for microorganisms to grow, thus achieving the role of product protection. Secondly, the stability of aluminum foil packaging bags is very good, generally not affected by the deterioration of the external environment.

Functionally, the two are very different.

First of all, because the lamination of aluminum foil bags is pure aluminum foil, it is far stronger than aluminum-plated bags in terms of moisture resistance, light resistance, water resistance and oxidation. Durable is the word of aluminum foil bags. Both bags can print patterns, aluminum foil bags with soft hands and aluminized bags with hard hands. Therefore, aluminum foil bags are more suitable for food, medicine, chemical products, some electronic parts, mechanical parts due to the need to seal aluminum foil bags are often used. Aluminized bags are used for fast products, not to say that the aluminized bags are not good, just to prove that the aluminized bags are cost-effective. Some electronic parts, mechanical parts due to the need to seal the aluminum foil bags are often used. Aluminum-plated bags are used for fast products, not to say that the aluminum-plated bags are not good, just to prove that the cost performance of aluminum-plated bags is very high. Some electronic parts, mechanical parts due to the need to seal the aluminum foil bags and often use. Aluminum-foil bags are used for fast products, not to say that the aluminum-plated bags are not good, just to prove that the cost performance of aluminum-plated bags is very high.

Coleson Packaging only makes high quality aluminum foil bags with opaque, silver white, anti-gloss, good barrier, high and low temperature resistance, oil resistance, heat seal, light blocking, fragrance retention, odorless, soft and so on and so forth.
