What is extra thick aluminium foil sheet

  Speaking of aluminium foil thickness, we think of 0.09mm or 0.1mm. Usually foil aluminium is not over 0.2mm thick, but there are thick aluminium foil sheet and even extra thick aluminium foil rolls. And the usage are quite familiar to us: transformer winding and sealing liners.

  Transformer aluminium foil rolls mainly refer to aluminium strip 1060. While being used for transformers, it is an extra thick aluminium foil, with a thickness between 0.2mm and 3mm. 1060 O aluminium foil is used for winding units of high and low voltage in dry type transformers to achieve conversion and impedance matching between different voltages (currents). The traditional winding material for transformers is copper, which is much more expensive. People have been looking for an alternative of copper. The conductivity of metals are successively silver, copper, gold, aluminium, nickle and steel. Since the conductivity of aluminium is only second to copper, it becomes the best alternative as a transformer winding material. But the requirements for transformer aluminium foils are really high, and only powerful suppliers are able to supply them.

  In addition to 1060 extra thick aluminium foil sheet, there is thick aluminium foil sheet, too. Take 8011 aluminium foil used for sealing liners for example. A roll of 8011 foil aluminium can be as thin as 0.016, but thick ones reach 0.5mm thick. Both thicknesses can be used as sealing liner materials, but in varied application conditions. Thick aluminium foil sheet products have natural advantages in sealing bottles and other containers. They display an excellent insulation property, protecting sealed materials (food, medicine, make up etc.) from moisture, gases, smells etc, keeping them fresh as long as the liners are not removed.

Anti-rust measures in storing aluminium foil roll for food

  Because of its excellent performance, an aluminium foil roll has a wider range of applications in life. At present, commonly used aluminum foil rolls are of grades 1060, 1235, 3003, 8011, 8021, 8079 etc., which are widely used in food, beverage, and pharmaceutical packaging materials, and which have good applications in industrial fields such as electrolytic capacitor materials and lithium ion batteries.

  The most advantageous performance of the aluminum foil roll is used as a packaging material. It has the characteristics of good barrier property, strong light-shielding property, high mechanical strength, air-tight moisture-proof, heat preservation and fragrance-free, safe and non-toxic. With the rise of the packaging industry, the demand for aluminium foil for food packaging is increasing year by year. At the same time, 8011 aluminum foil and 8079 aluminum foil are often used as materials for high-grade pharmaceutical packaging. Also called aluminium foil paper, an aluminum foil is a soft metal film, often in the form of aluminum foil coils. The safe storage and anti-corrosion measures of aluminum foil rolls are very important. Let’s take a look at how to do it.

aluminium foil roll for food packaging

  1. The packaging of aluminium foil for food should be sealed and the appropriate amount of desiccant should be placed in each roll to ensure no water in the compressed air.

  2. Strictly control humidity and temperature. The humidity of the wooden shaft and the box board of the package is not more than 18%, and the temperature of the packaged aluminum foil roll is not more than 45 °C.

Aluminium Foil Thickness

  How thick is aluminium foil? Generally aluminium foil thickness ranges between 0.009mm and 0.2mm. In practice, there is even 0.5mm. Different thicknesses match different aluminium foil uses. Here we will give a detailed introduction to thickness of aluminium foil.

  How Thick is Aluminium Foil

  The aluminium industry divides its products by thickness into aluminium sheets and aluminium foil rolls, in which it regards sheets with a thickness below 0.2mm (sometimes even 0.1mm) as foil materials. If you do a careful research, however, you will find that the thickness of aluminium foil reaches 0.5mm and even more in some practical uses. Thus the thickness range is developing with technology and process. Thinner and thicker foil rolls are produced nowadays. Here we list aluminium foil thickness ranges related with different uses.

  Aluminium Foil Thickness and Its Uses

  A. Food container aluminium foil

  The thickness of food container aluminium foil is generally between 0.03mm and 0.20mm, and can be divided into wrinkle and wrinkle-free. In fact, it is a 3 or 8 series aluminum ingot raw material. After cold rolling or hot rolling, it has a uniform thickness, smooth surface, no pinholes, no dust particles, no odor, aluminum foil parent roll. The production process is a one-time automatic cold stamping forming of special equipment and molds. Alloys available for food container aluminium foil rolls are 8011, 8006, 3003, 5052, 3004 aluminum foil.

Second, learn as more details in advance as possible, like lead time, quality control, after sales service, payment term etc. Third, learn something about currency ratio before putting an order, and choose the best time when the ratio is favorable for you. And if you can learn more about local financial knowledge which your supplier make as a base before giving you an offer, you would harvest more than you expect.

Answers to usual questions about aluminium foil tape uses

  Q1: What are aluminium foil tapes?

  A1: An aluminum foil tape is made of aluminium foil and coated with acrylic adhesive. It has high peel strength, excellent adhesion and oxidation resistance, good corrosion resistance and good flame resistance. It is available in several types, such as ordinary tapes, conductive tapes, high-peel tapes, reinforced tapes, marine welded tapes, heater-specific tapes, etc.

  Q2: What are functions of aluminium foil tapes?

  A2: The purity of an aluminium foil roll for tapes are 99.95% and more. This enables a tape to prevent human bodies from EMI and insulate unnecessary voltage. The aluminum foil tape is bonded to the joints of all the aluminum foil composite materials, the sealing of the insulation nail puncture site and the repair of the damaged portion. It is mainly used as the main raw and auxiliary materials for refrigerators and freezers production plants, and is also a must-have raw material for the insulation materials distribution department. It can also be used for steam tube outer wrapping to prevent temperature loss.

  Q3: Can an aluminium foil tape be used for pot repairing?

  A3: Yes. Completely clean the damaged area of the pot, and no water or oil should be left on the surface. The tape should be pressed flatly on the area.

  Q4: Can I use a pot to contain drink water after repairing the pot with aluminium foil tapes?

  A4: The main ingredient of the tape is still aluminum. As long as the temperature is not too high (100 degree and less), it’s safe to use. Although some people believe that excessive intake of aluminum might lead to dementia, a small amount of aluminum here does not harm to your health.

  Q5: Why do aluminum foil tapes have an insulation function?

  A5: The aluminum foil itself does not insulate heat at all. In contrast, it is a good conductor of heat. If you wrap a pipe with an aluminium foil roll, there’s no use at all in heat insulation. You should wrap the pipe with some insulation cotton and then wrap the cotton with aluminum foil. Aluminum foil is actually the conduction of the outside temperature to protect the temperature inside from the outside world.

This shows aluminium foil for tapes.

  Q6: How much temperature can aluminum foil tape withstand? Are there any other high temperature and rain withstanding tapes?

  A6: Aluminum foil tape is usually aluminum foil plate that can withstand temperatures above 300°. The adhesive tape of the tape generally looks at the specific material, and most of them can withstand high temperatures of about 180°.

  Q7: How are the electromagnetic shielding effects of aluminum foil tapes and copper foil tapes? Which type is better?

  A7: The shielding effect is the same, but copper tapes are more frequently applied because they gets oxidized less easily and can be welded more easily.

  Q8: What is the difference between aluminum foil tape and aluminum foil non-slip tape?

  A8: The functions are different. One is for preventing slip and the other for sticking things together.
