Aluminum foil

Aluminum foil is a kind of foil stamping material that is directly calendered into thin sheets with metallic aluminum, and its stamping effect is similar to that of pure silver foil stamping, so it is also called fake silver foil.

According to the thickness, aluminum foil can be divided into thick foil (thickness of 0.1 ~ 0.2mm), single zero foil (thickness of 0.01mm and less than 0.1mm/ foil), double zero foil (0.005 ~ 0.009mm aluminum foil); according to the shape, aluminum foil can be divided into rolled aluminum foil and sheet aluminum foil; according to the state, can be divided into hard foil, semi-hard foil and soft foil.

According to the surface state, aluminum foil can be divided into one-sided light aluminum foil and two-sided light aluminum foil.

According to the alloy series, it can be divided into

According to the surface treatment, it can be divided into

Parameters of aluminum foil

  • Al metal alloy: 1xxx, 3xxx, 8xxx series, etc
  • Alu temper: O - H112 etc
  • Thickness: 0.006mm - 0.20mm
  • Width: 50mm - 1500mm

Features of Aluminum Foil

  1. Very good elongation, anti-corrosion
  2. Generally used in industry and architecture industries
  3. Suitable for making tableware, receptacles
  4. Packing: Covering with brown paper and plastic bag then packed with wooded plywood then directly loading into the container for transshipment

Advantages of aluminum foil

  • Cheap, reusable, and recyclable, it is a popular environmental protection material in the world today.
  • The beautiful aluminum foil container is leakproof, strong, easy to clean, and keeps food fresh. Aluminum has good conductivity and can speed up baking and freezing. Compared with other packaging materials, aluminum foil containers can restore their original appearance faster and better.
  • The use of environmental protection aluminum foil containers does not cause any impact on the environment. It is safe and convenient to use. Using aluminum foil containers to pack fast food instead of plastic products can protect the environment and reduce white pollution.

Aluminum foil with a lightweight, airtight, and good cladding and a series of advantages, it is widely used in daily life, it is mainly used for packaging, electrical, and building three major areas.

Aluminum foil by shape can be divided into rolls of aluminum foil and aluminum foil flake. Aluminum foil processing wool most rolls in supply, with only a few hand industrial packaging occasions with flake aluminum foil.

Because of its excellent characteristics, aluminum foil is widely used in food, beverage, cigarette, medicine, photographic base plate, household daily necessities, etc. it is usually used as its packaging material; Electrolytic capacitor materials;

Thermal insulation materials for buildings, vehicles, ships, houses, etc;

It can also be used as decorative gold and silver thread, wallpaper, and decoration trademarks of various stationery prints and light industrial products.

Among the above applications, the most effective performance point of aluminum foil is as a packaging material.

Aluminum foil is a soft metal film, which not only has the advantages of being moisture-proof, airtightness, shading, abrasion resistance, fragrance preservation, non-toxic, and tasteless but also because it has elegant silver white luster and is easy to process beautiful patterns and patterns of various colors, so it is more likely to be favored by people.

In particular, after the aluminum foil is compounded with plastic and paper, the shielding property of aluminum foil is integrated with the strength of paper and the thermal sealing property of plastic, which further improves the shielding property of water vapor, air, ultraviolet, and bacteria as packaging materials, and greatly widens the application market of aluminum foil.

As the packaged goods are fully isolated from the light, moisture, and gas of the outside world, the packaged goods are well protected.

Especially for the packaging of cooked food, the use of this composite aluminum foil material can ensure that the food will not deteriorate for at least one year. Moreover, heating and unpacking are very convenient, which is deeply welcomed by consumers.

With the improvement of people's living standards and the development of tourism, the demand for beer, soda, and other beverages and canned food is increasing day by day.

All these need modern packaging and decoration to facilitate competition in the international market. In order to meet the market requirements, people have developed packaging materials such as plastic film and sprayed the foil with good shielding, but their comprehensive properties are not as good as overcoating and lamination.

Therefore, it can be said that aluminum foil is a perfect packaging material with a variety of excellent properties, which fully shows its broad application prospects in many fields.

In order to improve the rolling efficiency and the quality of aluminum foil products, the modern aluminum foil rolling mill is developing in four directions: large coil, wide width, high speed, and automation.

The roll body width of a contemporary aluminum foil rolling mill has reached more than 2200mm, the rolling speed has reached more than 2000m / min, and the coil weight has reached more than 20t.

The corresponding automation level of the rolling mill is also greatly improved. A thickness control system (AGC) is generally installed, and most of them are installed with a flatness gauge (AFC). The aluminum foil industry is facing a period of rapid development.

These products are used as insulation material, packaging material, used in buildings insulation, construction insulation.

The material provides excellent insulation: reflects up to 97% of radiant energy in addition to resisting other types of heat transfer from conduction, convection, and radiation.

The side of Metalized PET/Alu forms an effective barrier against moisture, air currents, and vapors. It is an Economical solution in many fields.
