What thickness is used for packaging aluminium foil?
Generally, the thickness of packaging aluminium foil is between 0.03mm and
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.
Aluminum foil packaging can be tailored to different specifications and styles of packaging bags, mostly using four-layer structure, with good water and oxygen insulation function.
Aluminum foil packaging surface will generally have reflective gloss, which means that it does not absorb light, but also uses multi-layer production. Therefore, aluminum foil paper not only has good shading, but also has a strong isolation, and because of the aluminum component in it, it also has good oil resistance and softness.
Aluminum foil packaging bags have strong air barrier, anti-oxidation, waterproof, moisture-proof, strong mechanical properties, high explosion resistance, puncture resistance and tear resistance. Aluminum foil packaging bags have good heat resistance, low temperature resistance, oil resistance and fragrance retention. It is non-toxic and odorless, and meets the hygienic standards of food and drug packaging. Good heat sealing performance, flexibility, high barrier performance.
Aluminum foil packaging bags are suitable for packaging various circuit boards, electronic products, precision machinery accessories, consumer goods, industrial products, etc. For example: PC board, IC integrated circuit, electronic components, SMT patches of all kinds of LED wilderness, lamp packaging, precision hardware, auto parts and other packaging.
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
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
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
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
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
Aluminum alloy is a silver solid. Available as sheets, strips, foil, shots, wire, powder, and granules. melting point of aluminum foil: 2327 oC Melting point: 660 oC ,so it is safe.
So aluminum foil or called tin foil is often used in the kitchen, but some
people use it for other reasons as well, such as covering windows elsewhere in
the house. Foil is used in this way for a variety of reasons. The properties of
tin foil make it useful in multiple applications.
Tin foil works effectively to block radiant heat. Because of this, some
people use it to block the heat of the sun by securing it over windows. The foil
is simply placed over the glass window panes — on the inside of the house —
and secured with tape. Because tin foil is resistant to heat, it prevents much
of the sun’s heat from entering the house. This helps cut down on energy costs
because the air temperature inside remains more constant, despite the sun’s
location and the temperature outside.
why aluminum foil on windows becoming more and more popular?
The gold aluminum foil is a solid metal that you cannot see through. The foil
is a low-cost alternative to blinds and other window coverings. If a person
lives on a bustling block filled with passersby, covering windows in tin foil
grants him the ability to be in his home without being seen.
The physical properties of tin foil make it an impenetrable barrier to light.
The positioning of some windows allows light to shine brightly into the home as
the sun rises and sets, which may create an unwanted glare. The light can shine
into bathrooms, making it difficult to apply makeup in a bright mirror, and it
can create glares on television and computer screens. Covering these windows
with aluminum foil prevents the sun from shining brightly into rooms and allows
for shade. For similar reasons, some people who work overnight shifts cover
their bedroom windows with aluminum foil to help them achieve total darkness for
easier daytime sleeping.
Aluminium Foils Costs and Benefits
Aluminum foil is inexpensive. It is a low-cost substitute for window curtains
or energy-efficient window treatments. Aluminum foil is also malleable, which
makes it easy to conform to different window shapes. It keeps its shape, so as
long as it is secured with tape, it will not detach or shrink away from the
windows. Although not particularly decorative, tin foil is a practical choice
for covering windows.
Generally, the thickness of aluminum foil for Packaging is between 0.03 mm and 0.1 mm. This is because the packaged article is sufficiently isolated from the outside light, moisture, gas, etc., so that the package is well protected. Especially for the packaging of retort foods, the use of this composite aluminum foil material can at least guarantee that the food does not deteriorate for more than one year. Moreover, heating and unpacking are very convenient and are very popular among consumers.
This is related to the characteristics of aluminum foil.

its tear strength is small, so that it is easily torn.
(9) The aluminum foil itself cannot be heat-sealed and must be coated with a
heat-sensitive material such as pe to be heat-sealed.
(10) When aluminum foil is in contact with other heavy metals or heavy
metals, there may be adverse reactions.
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.
Household use standard duty aluminium 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.
Some users prefer a thin pliable foil for a variety of home use and
commercial needs. Most standard duty or economy foils are often much more
affordable than heavy duty or extra heavy duty foils. Some users do not prefer
the standard duty foils because of easy tearing and burning when baking.
Heavy Duty Aluminum Foil – Many cooks use it for baking, grilling, and
storage. Most Aluminum foil rolls labeled “Heavy Duty” are between .0008 thick
and .001 thick.
Extra Heavy Duty Foil – A harder thickness to find, but some manufacturers do
produce extra heavy duty foil. It provides excellent tear resistance and works
well with everything the heavy duty and the standard foil is used for. Most
aluminum foil labeled “Extra Heavy Duty” are between .0011 thick and .0016
Is aluminum foil recyclable?Aluminum is one of the highest-value materials
you can recycle, and it can be reprocessed into new aluminum in just 60
days.Aluminum is used for more than foil aluminum, of course. Cans, cars, even
my laptop is made of aluminum. Aluminum compounds are used as catalysts in
chemical reactions to make elemental sulfur and various hydrocarbons, which can
be starting materials for making plastics, medicines, fertilizers, rubber
products and more.
Aluminum foil thickness is made from the same material as soda cans (aluminum), but since it’s most often contaminated with food waste or combined with plastic (like with yogurt tops), there’s no guarantee you can recycle it with your aluminum cans.
Aluminum Foil Recycling Preparation,How to recycle aluminum foil?
You want to make sure that aluminum foil is as clean as possible before
recycling. While burns and holes won’t affect the recycling market, you’ll want
to remove any meats or sauces from the foil.
If you’re recycling aluminum foil that you bought and used for storage,
separate the foil from the paperboard box and corrugated tube before
If foil is combined with other materials (such as in drink boxes, candy
wrappers and yogurt tops) and can’t be separated, you’ll want to throw it away.
Foil mixed with other materials is considered recycling contamination.
Combine all sheets of thick aluminum foil into one ball. This will keep the
material easily separated from other products, and also prevent it from blowing
away (aluminum foil is a very light material).
Your first step is to make sure your aluminum foil is devoid of food waste.
You can rinse off small bits of food, like cookie crumbs and fruit or vegetable
juice. The foil may discolor if you use hot water, but that is totally normal.
If the foil is very heavily soiled with oily or greasy foods like meat,
frosting, gravy or butter, it will need to go in the trash.
Your second step is to determine if your curbside recycling program accepts
aluminum foil. you will need to find another way to recycle your aluminum foil.
Before placing any foil in your recycling bin, crumple it into a ball so it will
not get torn or stuck in the recycling machinery. Do not take each individual
piece and ball it up so that you have several tiny spheres. Instead, save up
your aluminum foil and make a ball that is at least two inches in diameter. And
again, make sure it is clean before you place it in your recycling bin. Keep in
mind that several food products come with aluminum foil pan attached. Many
yogurt containers have aluminum foil over the lids. K-cups also have aluminum
foil lids. If you can recycle sheets of aluminum foil, chances are high you can
recycle these items as well. Check with your recycling company to see if they
can take other types of clean aluminum food storage products, like pie pans and
turkey roasters, too. I reuse my clean aluminum foil whenever possible.
At present, air conditioning is gradually developing towards the direction of miniaturization, high efficiency and long life. The heat exchanger of air conditioning is also developing towards ultra-thin and high strength. In the 1980s, the thickness of heat exchanger was 0.15-0.2 ram, whereas today’s thickness is only between 0.09 and 0.15 mm. In order to improve the life of air conditioning, reduce power consumption, improve ventilation quality and improve refrigeration effect, a variety of functional hot plates have been produced. Aluminum foil for air conditioning can be divided into 7 categories according to its processing technology and performance characteristics.
1. Non-coated aluminium foil
Non-coated aluminium foil refers to the aluminium foil which has been rolled
and annealed and whose surface has not been treated in any form.
2. Coated aluminium foil
Coated aluminium foil is the surface reprocessing of uncoated aluminium foil
to make it have some special functions.
3. Corrosion Resistant Aluminum Foil
The surface of corrosion-resistant aluminium foil product has a certain
corrosion-resistant protective layer. The air-conditioning heat exchanger sheet
made of this product can be used in harsh areas, and can significantly improve
the service life of air-conditioning. At the same time, due to the improvement
of corrosion resistance of heat exchanger, the formation of corrosive powder on
the surface is greatly reduced, thus improving the ventilation quality and
purifying the air in the air conditioning room.
4. Hydrophilic Aluminum Foil
The surface of hydrophilic aluminum foil has strong hydrophilicity. The
hydrophilicity is determined by the angle formed when water is adhering to the
surface of aluminium foil. The smaller the angle a, the better the
hydrophilicity, and vice versa, the worse the hydrophilicity. Generally
speaking, angle a is less than 35. It belongs to hydrophilic property.
Hydrophilic aluminium foil is commonly used in air conditioning condensers. Its
main function is to make the moisture in hot air condensate into droplets on the
heat exchanger sheet, which is easy to spread out and flow downward along the
sheet. In this way, the effect of ventilation of heat exchanger is avoided
because of the “bridging” of water droplets between heat exchangers, so as to
improve the heat exchange rate of air conditioning and save electricity under
the condition of the same refrigeration capacity. At present, the general
hydrophilic aluminum foil on the market not only has good hydrophilicity on the
surface, but also has high corrosion resistance, which makes the performance of
air conditioning more optimized.
5. Hydrophobic Aluminum Foil
Hydrophobic aluminium foil is also called water repellent aluminium foil. Its
surface properties are just the opposite to those of hydrophilic aluminium foil.
That is to say, when condensate condenses to the surface of the aluminum foil,
the contact angle between the condensate and the aluminum foil is larger,
generally at 75. Above. The bigger the angle, the better the water repellency.
The ultimate purpose of using hydrophobic aluminium foil is the same as
hydrophilic aluminium foil, that is, to keep condensate between heat exchangers.
The difference is that hydrophobic aluminium foil can remove the condensate
between heat exchangers by increasing the contact angle between condensate and
heat exchanger to form water droplets which are easy to slip.
6. Self-lubricating aluminium foil
In the process of manufacturing air-conditioning heat exchanger, lubricant
should be added on its surface first, then punched and flanged, and then washed
off with trichloroethylene. Because trichloroethylene is harmful to human body,
in order to reduce this process, self-lubricating aluminium foil is produced
accordingly. Self-lubricating aluminium foil, as its name implies, does not need
to be lubricated separately in its punching process. The lubrication of
self-lubricating aluminium foil during punching is assumed by the pre-treated
film on the surface of aluminium foil. Since no special lubricant is required,
subsequent cleaning and drying processes of trichloroethylene are omitted.
7. Anti-mildew Aluminum Foil
Anti-mildew aluminium foil is mainly used in the air-conditioning part of the
indoor machine. Its main function is to prevent the surface of heat exchanger
from mildewing due to its long use or placement time, thus significantly
improving the air quality of air-conditioning, preventing abnormal odor and
effectively improving the indoor environment of air-conditioning.
The production of aluminum foil plate usually starts out the same way as plate but the slab is further rolled through a continuous mill to reduce thickness and wound into a coil at the end of the line. These coils are subsequently cold rolled, from one to several passes at cold rolling mills. Coils may be heated in a furnace to soften it for further cold rolling or produce the desired mechanical properties. Cold rolling is the last step for some sheet, but other types (referred to as heat-treatable) are subjected to further elevated-temperature processing to increase their strength.
Some aluminum sheet and foil products may also be produced using the
continuous casting process in which molten metal enters the caster, which
produces a hot rolled coil, thus bypassing the ingot casting and hot rolling
Aluminum foil is one of the materials used in the creation of labels, and is
considered a prime choice when you need to create labels that can withstand
varying temperatures, and adverse weather conditions. Aluminum foil can be used
in very cold environments and very hot areas too. This material is also
non-combustible and flame-resistant, and does not produce any toxic fumes even
when exposed to high heat. This is why labels made using this are often chosen
by companies for applications that place such tags in such situations.
Aluminum foil as a material for your labels is a good choice when you require
a label that has a metallic look, lightweight, and cost-effective. It is also a
great choice when you know your labels will be used in varying conditions, and
when you require a versatile and durable label for such conditions. This
particular material type is great for the creation of asset and inventory tags,
calibration labels, serial number tags, and many more. Since aluminum foil is
non-magnetic and does not spark, it is also a great choice for a lot of
high-voltage applications and for use with electronic devices. It is also a good
option for when you need a metallic looking tag but do not want the weight and
the thickness that often comes with metal nameplates.
Aluminum foil provides a complete barrier to light, oxygen, moisture and bacteria. For this reason, foil is used extensively in food and pharmaceutical packaging. It is also used to make aseptic packaging that enables storage of perishable goods without refrigeration. (more…)
