When it comes to the use of aluminium foil, you will think of the aluminium foil packaging. That is because we can see a thin layer of aluminium lunch box when we buy some food. But the use of aluminium foil is very extensive.

Aluminum foil for air conditioner

Aluminum foil for air conditioning is a special data for the manufacture of heat exchangers for air conditioning. The early used alu foil for air conditioning is component foil. In order to improve the surface properties of aluminium foil, anticorrosive inorganic coatings and hydrophilic organic coatings were coated before forming to form hydrophilic foil. At present, hydrophilic foil accounts for half of the total air conditioning consumption, and its utilization rate will be further improved. There is also a hydrophobic foil, which makes the appearance of the fin hydrophobic and avoids the adhesion of condensation water. As hydrophobic foil improves the appearance of thawing technology, there is little production practice at present due to further research.

The thickness of air-conditioning aluminum foil is 0.1 mm to 0.15 mm. With the development of technology, air-conditioning aluminium foil has a further refinement trend, and the thickness of the leading product of aluminum foil is 0.09 mm. In the extremely thin state, aluminum foil has a good shape, its internal design and performance requirements are uniform, small metallurgical defects, less anisotropy, with high strength, good ductility, uniform thickness, good flatness.

Aluminum foil for cigarette packaging

China is the largest cigarette producer and purchasing power in the world. At present, there are 146 large cigarette factories in China, which produce 34 million large boxes of cigarettes and packages of cigarette foil every year. At the same time, 30% choose spray aluminium foil, 70% use calendar aluminium foil and calendar aluminium foil. The consumption of calendar foil is 35,000 tons. With the improvement of citizens’health awareness and the impact of foreign countries on cigarette imports, the demand for cigarette aluminum foil increases. The total demand for cigarette packaging aluminum foil in China accounts for Aluminum foil, at present, two or three domestic aluminium plate manufacturers can produce high-quality foil, technical level and suitable for the world, but the overall quality of domestic foil and the world default value have a certain distance.

Decorative Aluminum Foil

Decorative aluminum foil uses decorative information through aluminium-plastic composite method. It has the characteristics of good color, high reflectivity, light and warmth. Mainly used in architecture, furniture decoration and some gift box packaging. Decoration foil in China’s construction industry has rapidly extended from Shanghai, Beijing, Guangzhou and other key cities to the whole country since the early 1990s. In recent years, the demand for decoration aluminum foil has increased dramatically. It is usually used as information for building walls and interior furniture decoration, and it is also used in the facade and interior design of commercial institutions.

Decorative aluminium foil has the advantages of thermal insulation, moisture-proof, sound insulation, fire prevention, easy cleaning and so on. It has luxurious appearance, processing equipment and fast construction machinery. At present, China’s construction and home decoration industry has formed a trend of using decorative foil. With the rapid development of China’s construction industry and the continuous popularization of decorative foil, the demand for decorative foil will also increase greatly. In addition, the choice of decorative foil packaging abroad is very popular, in recent years in China’s rapid development, it is estimated that there will be better prospects.

Aluminum foil for cables

Cable aluminium foil is sealed and shielded with aluminium foil. It is coated on one or both sides, including aluminium-plastic composite foil, and used as cable shield. Cable foil needs less oil, no holes, high mechanical properties and low overall quality.

Recyclability and cleanliness of aluminium foil

One characteristic of aluminium is that it can be recycled 100% and reused. It can also retain its original characteristics. The regeneration process of aluminium consumes only 5% of the energy consumed by the original production of aluminium, so the emission of harmful gases will be significantly reduced during the regeneration process. Current separation technology can extract aluminum from scrap aluminium products for household use, but requires very little energy.

Aluminum foil is recyclable if it’s free of food residue. Do not recycle dirty aluminum because food contaminates recycling. Try rinsing the foil to clean it; otherwise, you can throw it in the trash.

on the other hand,tin foil was the first commercially available foil and was in use from the late 1800s through the early 1900s. What we call “tin foil” today isn’t the same although it still persists. Luckily aluminum foil does not add a metallic aftertaste like true tin foil.

According to the knowledge of aluminium foil processing factories, if the aluminium foil is not recycled, but directly disposed of in the incinerator, then a characteristic of aluminium appears. After heating, the surface of aluminium foil will oxidize quickly, and then release a lot of energy, which can also be recycled. At this time, aluminium without oxidation will melt and be recycled in the bottom ash of the incinerator.

The aluminium foil manufacturer introduced that the aluminium foil can be applied to various heating methods, such as convective heating oven and microwave heating oven, as well as air oven, and can also heat food packaged with aluminium foil. The use of aluminum foil packaging can greatly shorten the preparation time of cooking, but also can save a lot of energy.

Recycling Aluminum Foil – Unlike cans, recycling aluminum foil is tricky since cans maintain a rigid cylindrical or square shape which makes them easy to rinse. Foil pieces though are almost like paper sheets.

Clean the foil to prepare for it to be sent to the center. One way to do this is to wipe the foil clean. There will be times when the food is tightly stuck to the foil and no amount of wiping will get rid of it. If so, cutting off those sections is the only way to go.

Deliver the cleaned and ready-to-recycle aluminum foil to the local recycling center.

Sometimes you need something a little stronger than standard aluminum foil. That’s where heavy duty aluminum foil comes in. Our heavy duty foil offering is ideal for tough jobs like:

lining pans for use in the oven

freezing meals ahead or storing leftovers

making foil packets to lock in moisture and flavor when you grill

Where this really matters is when you’re using aluminum foil for cooking. Since regular aluminum foil is thinner than the heavy-duty version, it doesn’t stand up to high heat and weighty items as well.

Heavy duty aluminum foil offers perfect protection against both high heat and freezing cold. Heavy Duty Foil is also available in a wider 18 inch roll, making it perfect for covering or lining larger roasting pans or making or folding larger foil packets.

Aluminum foil rolls and sheets come in a variety of thicknesses, widths, and lengths. Manufacturers often make the width and length of the foil roll easy to find, but the thickness of the foil is often not advertised. Most manufacturers use terms like standard duty, heavy duty, and extra heavy duty to describe foil thickness. Finding the actual thickness from a foil box or manufacturers website is not likely.

This type of heavy duty foil is thicker and sturdier than regular aluminum foil. It’s tough enough to stand up to high heat, heavy food items, and long-term storage in the freezer. Because of the extra thickness, it’s also a better choice for campfire packets.

Regular /Standard Duty and extra heavy duty aluminum foil are made of the same material, but there’s a key difference: the thickness of the foil.

Standard Duty Aluminum Foil – Most standard duty aluminum foil rolls are economical aluminum foil rolls for commercial and home aluminum foil sheets use. Home use standard duty foil rolls are often between 75 ft. and 250 ft. long, offered in a variety of widths. The majority of foil rolls labeled as “Standard Duty” are between .0004 thick and .0007 thick. Which at best is slightly over or one half of a mil in thickness.

Thickness of Aluminum Foil

Heavy Duty Aluminum Foil – By far the most common aluminum foil used for home and commercial use. Most home users buy 75 ft. rolls of Reynolds aluminum foil or a comparable brand for home use. Heavy duty foil provides extra strength and tear resistance. Many cooks use it for baking, grilling, and storage. Most Aluminum foil rolls labeled “Heavy Duty” are between .0008 thick and .001 thick. The extra three thousandths of an inch makes a big difference for a variety of applications.

In a word,This extra-heavy duty aluminum foil comes in a box with a standard cutting edge. It is good for use in cooking, serving and freezing food. Lining pans with roll before cooking makes cleanup easy. Use for grilling to lock in flavor and for freezing to prevent freezer burn. Material(s): Aluminum; Length: 500 ft; Width: 18 in; Packing Type: Box.

What are the processes of aluminium foil for air conditioning

There are two processes for aluminium foil for air conditioning:

(1) Cast rolling -cold rolling trimming -cold rolling -box rolling slitting- finished product annealing -packaging.

(2) Ingot -homogenization annealing -hot rolling -cold rolling- trimming cold rolling -box rolling slitting -finished product annealing -packaging.

Aluminum foil can be divided into industrial aluminum foil and packaging aluminum foil. The chemical composition of industrial aluminium foil is relatively pure, and its thickness is 0.005-0.2 mm. It is mainly used as capacitors, insulation materials and moisture-proof materials in electrical and electronic industries. The thickness of packing aluminium foil is generally 0.007-0.1 mm. There are many kinds of products, such as flat foil, printing foil, colored printing foil and laminated foil. They are mainly used as packaging materials for food, tea, cigarettes, etc.

The smaller thickness and width of aluminium foil produced by belt production method can reach 0.0025 mm and 1800 mm respectively.

Aluminum foil rolling is seamless rolling, and the rolls are always in the state of elastic flattening. During rolling, the thickness of alu foil can be controlled by adjusting rolling force, rolling speed and tension. In rough rolling, the thickness ofalu foil is controlled by rolling force; in finishing rolling, the alu foil thickness decreases with the increase of rolling speed; the greater the tension, the smaller the thickness; in order to prevent fragmentation, the tension is usually chosen as 0.2-0.4 of standard yield strength_0.2 of foil.

In low-speed rolling, the “thick oil-a00 aluminium plate rdquo” is often added to lubricating oil, or “thin oil” is used to adjust the rolling thickness of aluminium foil. Lubricant and roll condition have a very important influence on aluminium sheet foil quality.

Aluminum foil billet comes from cold rolled aluminium coil. It is generally pre-annealed at 340-480 C, and its thickness is 0.4-0.7mm. The pass deformation rate is about 50% and the total deformation rate is over 95%. The foil whose finished thickness is less than 0.01-0.02 mm should be rolled and rolled in double sheets.

Aluminum foil is widely used in many sectors of national economy and people’s daily life because of its light weight, good sealing and encapsulation, but it is mainly used in packaging, electromechanical and construction fields. Aluminum foil can be classified according to its thickness, shape, state or material.

Aluminum foil can be divided into thick aluminium foil, single zero aluminium foil and double zero aluminium foil according to thickness difference.

Thick foil: Aluminum foil with thickness of 0.1-0.2 mm.

(2) Single zero foil: aluminium foil with thickness of 0.0lmm and less than 0.1mm/

(3) Double zero foil: The so-called double zero foil is the aluminium foil whose thickness is less than 0.0075 mm, which has two zero foils after decimal point when its thickness is measured in mm. When expressed in English, thick aluminium foil is called “heavy gauge aluminium foil”, single zero aluminium foil is called “medium gauge foil” and double zero foil is called “light gauge foil”. Aluminum foil with thickness less than 40 LTM is sometimes called light gauge foil in foreign countries, while aluminum foil with thickness greater than 40 BTM is collectively called heavy gauge foil.

Aluminum foil can be divided into aluminium foil roll and aluminium sheet foil according to its shape. Aluminum foil deep-processed wool is mostly supplied in rolls. Only a few handicraft packaging occasions use aluminium sheet foil.

Aluminum foil can be divided into hard aluminium foil, semi-hard aluminium foil and soft aluminium foil according to its state.

(1) Hard foil: Aluminum foil without softening treatment (annealing) after rolling and without degreasing treatment, the surface is marked with residual Shantou. Therefore, the hard aluminium foil must be degreased before printing, bonding and coating. If it is used for forming, it can be used directly.

(2) Semi-hard aluminium foil: Aluminum foil whose hardness (or strength) is between hard foil and soft foil is usually used for forming.

(3) Soft foil: Aluminum foil softened after full annealing after rolling, with soft material and no residual oil on its surface. At present, soft foil is used in most applications, such as packaging, composite, electrical materials and so on.

Aluminum foil can be divided into one-sided and two-sided according to its surface state.

(1) One-sided glossy aluminium foil: double rolled aluminium foil, after coiling, one side is bright, – face is black, such aluminium foil is called one-sided glossy aluminium foil. The thickness of one-sided aluminium foil usually does not exceed o.025mm.

(2) Two-sided aluminium foil: single rolled aluminium foil, two drawings contacted with rolls. The two sides of aluminium foil can be divided into mirror two-sided aluminium foil and common two-sided aluminium foil because of the different surface roughness of rolls. The thickness of dihedral aluminium foil is generally not less than 0.01mm.

Aluminum foil can be divided into plain aluminium foil, embossed aluminium foil, composite aluminium foil, coated aluminium foil, colored aluminium foil and printed aluminium foil according to the added state.

Plain aluminium foil: Aluminum foil rolled without any other processing, also known as light foil.

(2) Embossed aluminium foil: Aluminum foil with various patterns on the surface.

(3) Composite aluminium foil: Aluminum foil and paper, plastic film, cardboard bonded together to form a composite aluminum foil. Coated foil: Aluminum foil coated with various resins or varnishes.

Coloured aluminium foil: The surface is coated with a single color of aluminium foil.

Printing aluminium foil: Aluminum foil, which forms various patterns, patterns, words or pictures on the surface by printing, can be a color, up to 12 colors.

What thickness is used for packaging aluminium foil?

Generally, the thickness of packaging aluminium foil is between 0.03mm and 0.1mm.

Due to the full insolation of the packaged goods from the outside light, humidity and gas, the packaged goods are well protected. Especially for the packaging of cooked food, the use of this composite aluminum foil material can ensure that food does not deteriorate for at least one year. Moreover, heating and unpacking are very convenient and popular with consumers.

Aluminum foil has a clean, hygienic and shiny appearance. It can be integrated with many other packaging materials, and the printing effect of the surface of aluminum foil is better than that of other materials. In addition, aluminum foil has the following characteristics:

(1) The surface of aluminium foil is extremely clean, sanitary, and no bacteria or microorganisms can grow on it.

(2) Aluminum foil is a non-toxic packaging material, which can be directly contacted with food without any health hazards.

(3) Aluminum foil is a odorless and odorless packaging material, which will not make the packaged food have any odor.

(4) If the aluminum foil pans itself is not volatile, the packaged food will never dry or shrink.

(5) Whether at high temperature or low temperature, there is no oil infiltration in aluminum foil.

(6) Aluminum foil is an opaque packaging material, so it is a good packaging material for sunshine products, such as margarine.

(7) Aluminum foil has good plasticity, so it can be used to package products of various shapes. It can also create containers of various shapes at will.

(8) Aluminum foil has high hardness and tension strength, but its tearing strength is small, so it is easy to tear.

(9) Aluminum foil itself can not be heated and sealed, so it must be coated with heat-resistant materials, such as PE, in order to be heat-sealed.

(10) Aluminum foil may have adverse reactions when it comes into contact with other heavy metals or heavy metals.

Double sided reflective aluminum foil insulation material

Aluminum foil thermal insulation can be used to multiple places where it can be found useful for stopping unwanted heat gain or heat loss. Aluminum foil insulation works effectively and efficiently and prevents the transmission of temperature that at the end results into wastage of energy.

Not your typical aluminum foil, our aluminum foil insulation is comprised of two layers of highly reflective aluminum reinforced with polyethylene woven fabric that gives the aluminum insulation an incredible tear resistance factor making it more durable that most radiant barriers in the market place.

Why aluminum foil insulation?

The barrier properties and heat reflectivity of aluminium foil are widely used in building panels to improve insulation performance in modern building systems.

Aluminum thermal insulation is work on the radiant barrier principal that reflects the temperature and sun rays back to atmosphere from where they are coming from. And it works in both hot and cold environment by reflecting high temperature rays to the direction of source. The same can enhanced with the use of polyethylene bubble insulation film that sandwiched between the aluminum foil. Though aluminum insulation reflects around 97 percentage of sun rays and radiant heat, remaining can be stop passing to home by air bubble film. And this is why most of the radiant barriers are the best choice for home and industrial temperature insulation.

Aluminium foil is used as a skin for heat-insulating and incombustible materials to provide high performance insulation for pipe work and ducting.

The adhesive tape used to secure the laminated material is based on aluminium foil or its reflective surface, corrosion-resistance and long life.

In electrical cables, aluminium foil helps give long-term insulation against moisture and attack from naturally occurring corrosive elements found above and below ground.

Aluminium foil also acts as an insulator against the magnetic and radio frequency emissions associated with electrical cables.

As a sheath for fiber-optic cables, aluminium foil uses its electrical conductivity to act as a “tracer” to enable testing of the integrity of cable links – as well as helping to provide the long-term protection every cable needs.

In fire walls for vehicles and fireproof doors and building panels, aluminium foil stops access to the oxygen required to support flames.

This aluminum roof insulation is used to provide protection against the higher cold also as it reduces the temperature loss to outers surface of the home roof or wall. Particularly for the building that are made with higher amount of glass or steel. Whatever needs to be of keeping the close room at a constant temperature, it can be benefited with the use of radiant aluminum foil.

Studies have shown that radiant heat transmission is responsible for the highest amount of heat gain or loss in the building structure. During the hard summer, the ceiling or roof and wall of the building absorb radiation from the sun rays and transmit it inside the home. The same heat is then transmitter towards the attic room. However, most of the sun rays and heat is transmitted outside when radiant aluminum foil insulation is used. Also during the colder period the same thermal barrier stops the wastage of energy by reflecting cooler temperature towards the interior of the building. A properly installed aluminum thermal barrier stops 97 percentage of the heat transfer and saves money and energy both.
