Reasons for aluminium foil as packaging material

Aluminium foil is used as a packaging material because it’s light, tensile and insulating.

Aluminium has a very small density, the smallest of copper, iron and aluminium. A piece of aluminum sheet of 9micro, for example, weighs only one third of a 9mc copper sheet of the same area. Meanwhile aluminium boasts an excellent tensile strength, which makes it possible for aluminium manufacturers to stress thick aluminum sheets into foils as thin as 9um. Owing to the fact that metal products are usually sold by weight, aluminum foil roll jumbo proves to be an overwhelming raw material for packaging in this regard.

In addition, aluminium foil rolls display an outstanding insulation to heat, air, light and moisture. This helps to extend shelf life of foods packaged by it. Opaque as the foil is, no light is able to penetrate through to damage the food. It acts like a well-armed protector.

Many people worry about safety problem of aluminium as packaging material, questions about which never disappears on quora, but up to now, there is no scientific evidence proving real harm to human health of aluminium packaging. The so-called “excessive taking in” of aluminium is based on a ridiculous number. However, it’s understandable if you are worried, since no one can prove that aluminum packaging is totally healthy, either. Therefore, you are advised to buy aluminum-packed foods of trustworthy brands who will use good quality foil rolls rather than inferior ones.

Aluminium foil for cigarette packaging

  An aluminium foil for cigarette packaging is the most commonly used composite film, usually containing pure aluminum (AL) and aluminum (VMPET). Its characteristics are as below.

  1. The aluminium as packaging material has a good mechanical strength, light weight, no thermal adhesion, good metallic luster, good light-shielding property, strong reflection ability to light, not easy to be corroded, good barrier property, moisture-proof and waterproof, airtight and nice fragrance.

  2. The packaging aluminium foil for cigarettes are metallic luster, gas barrier property, and low adhesion viscosity. After the composite processing, the aluminum plating layer transfer phenomenon is likely to occur.

  3. The aluminium foil for cigarette packaging has basically replaced asphalt moisture-proof paper because of its high softness, decoration and protection. It has become the leading packaging material for cigarette packaging, and will gradually withdraw the newly emerging aluminum-plated paper from the field of cigarette packaging.

  The combination of cigarette aluminium foil rolls adopts the wet bonding process, which has a better production efficiency, economy and environmental protection than the dry method and the hot melt bonding. It uses a water-soluble or water-dispersible adhesive to bond aluminum foil to a porous, highly hygroscopic liner, eliminating the problems associated with the use of enamel solvents in dry-laid applications, such as environmental pollution, residual solvents, additional waste gas recovery and discharge devices etc., so that the production process and products are more hygienic and safe.
