Excuse me: what is the recommended aluminum foil packaging for hotpot shops

it can grow on its surface and can be in direct contact with food without any danger to 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. Aluminum foil will not be soaked at high temperature or low temperature. The air and moisture transmittance are low, which can well protect the inner products. The aluminum foil itself is not volatile. 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. Stable performance, can adapt to various high and low temperature environments, and has certain corrosion resistance

why add a layer of pure aluminum foil to the packaging bag? Aluminum foil is also widely used as an isolation layer, heat exchange, and as a conductor. Usually, the thickness of aluminum foil used in paper wrapped beverage packaging and food packaging bags is only 6.5 microns. This thin aluminum layer can be waterproof, keep fresh, prevent harmful microorganisms and antifouling. It has the characteristics of opaque, silvery white, anti gloss, good barrier, high /low temperature resistance, oil resistance, heat sealing, optical opacity, fragrance retention, no odor, softness and so on

aluminized packaging bags are coated with a thin layer of aluminum powder on the plastic film to play a decorative role. Aluminum plated packaging bag is also called aluminum plastic packaging bag. Aluminum foil packaging bag, as the name suggests, is a kind of packaging bag with aluminum foil (pure aluminum) in the internal structure. Because the inner structure contains pure aluminum foil, it is referred to as aluminum foil packaging bag for short, also known as pure aluminum bag and aluminum platinum bag. In fact, aluminum foil bag is a bag made of a variety of plastic films and 99.9% pure aluminum layer, which is sealed and cut by bag making molding machinery. In terms of performance, the cooling effect is better than the aluminized bag. The pure aluminum bag is completely protected from light, and the aluminized bag is a shading effect. In terms of material, pure aluminum bag is pure aluminum with high purity and belongs to soft material; Aluminized bags mixed with composite materials are brittle materials. In terms of use, pure aluminum bags are more suitable for vacuum pumping, such as cooked food, meat and other products, while aluminized bags are suitable for tea, powder and so on. In terms of cost, the unit price of pure aluminum bag is higher than that of aluminized bag. Put the inside of the bag into the light or sunlight. What can see the light through the bag is plated aluminum foil, and what can’t be seen is pure aluminum foil

in appearance, there is little difference between the two. If the same product is placed in aluminized packaging, it may lose water and breed a large number of microorganisms within a month. In the aluminum foil packaging bag, a similar situation may not occur until half a year later. In order to ensure the quality of inner products, many packages are vacuum treated. After vacuum, the internal oxygen is reduced and the microorganism has no growth environment, so as to protect the product. Secondly, the stability of aluminum foil packaging bag is very good. Generally, it will not deteriorate under the influence of the external environment. From the function, the two are far apart. First of all, because the interlayer of aluminum foil bag is pure aluminum foil, its moisture-proof, light proof, waterproof and oxidation effect is much stronger than that of aluminum plated packaging bag. Durability is the endorsement of aluminum foil packaging bag. Both kinds of packaging bags can be printed with patterns. The handle of aluminum foil bag is soft and that of aluminum plated bag is hard. Therefore, aluminum foil bags are more suitable for food, medicine, chemical products, some electronic accessories and mechanical accessories. Aluminum foil bags are often used due to the need of sealing. The aluminized bags are mostly used for fast-moving products. This does not mean that the aluminized packaging bags are not good, but just proves that the cost performance of aluminized packaging is very high.
