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.

Why food is packed in aluminium foils

Why food is packed in aluminium foils? Traditionally, tin foil was the main food packaging foil, but now it is replaced with aluminum foil. This is because most of the aluminium foil papers nowadays are manufactured using vacuum coating technology. The cost is relatively low and the chemical properties are relatively stable. Most of the foil papers are manufactured by mechanical calendering. The price is higher and the use is far less extensive than that of aluminum foil paper. A food packed in aluminium foil is protected against light, moisture and heat. Let’s take chocolate for example.

food packaging aluminium foil manufacturers

Chocolates should be eaten immediately after being unpacked. If you want to save them, it is best to place it at a temperature of 12~18 degrees to avoid light, water and odor. Under such conditions, the oil crystals in the chocolate can be kept stable, the product is firm and brittle, and the appearance maintains a bright color. The storage time is generally more than 4 weeks, and the quality dark chocolate can be stored for a longer period of time than milk chocolate and white chocolate.

The chocolates produced in the factory usually have a shelf life of about 1 year, and those hand-made fresh chocolate desserts are best eaten as soon as possible. Although chocolate is not prone to spoilage, when the temperature reaches 20 degrees Celsius, the composition of the cocoa butter inside will melt and begin to separate. Once frozen, it will condense a white creamy substance on the surface, affecting the flavor. Therefore, chocolate is usually wrapped in food packaging foil paper and kept in a refrigerator.

Second, food packaging aluminium foil manufacturers says that aluminium foil packaging provides chocolates with a perfect environment with a maximum relative humidity of 65%. The water vapor in the air has a great influence on the quality of the chocolate. The special storage time is long. The chocolate products that have not reached the seal are prone to the so-called frosting phenomenon, and even deteriorate after the water vapor is absorbed. Winter is the best season for chocolate tasting. If the temperature is below 20 degrees Celsius, just store it in a cool, ventilated place.

When the summer temperature is high, put chocolate packed in food packaging foil in the lower refrigerator compartment of the refrigerator and do not put chocolates in the freezer. Also, when you just remove the chocolate from the refrigerator, do not open it immediately, let it warm back to room temperature and then open it. The outer layer of the chocolate will not condense the water mist to affect the appearance and taste.

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.

Features of excellent packaging aluminium foil

  Aluminium foil packaging and packing are more and more popular in industries like food process, pharmaceutics and cosmetics. Feature of excellent packaging aluminium foil are as below.

  First, the surface cleanliness of an aluminium foil packing should be high, and the surface should be free from oily dust, and the surface tension should be high. When using a simple method, that is, when testing with distilled water, it should be completely wetted, and the surface tension should be above 72 mN/m. If the oil is severe, the composite fastness will not be high, especially after high temperature cooking, delamination will occur.

aluminium foil packaging

  Second, the number of pinholes should be small. Originally, aluminium foil rolls should be the best barrier material, but if there is a pinhole, the barrier effect will be greatly reduced. Gas, moisture, and light will penetrate directly and quickly, and the contents will deteriorate quickly. In general, the thicker the aluminum foil, the less the number of pinholes.

  Third, the texture of the aluminum foil packaging should be soft, not easy to break when folded, and have good toughness. Purchased aluminum foil should be stored in a dry state, and should not be placed for too long, should be used as fresh as possible to prevent aluminum foil from absorbing moisture and deterioration.

Two types of aluminium foil packaging

  There are two types of aluminium foil packaging. One type is to wrap food or objects with aluminium foil jumbo roll (or made into aluminium foil trays or containers), the other with aluminium foil bags.

aluminium foil packaging

  Aluminum foil paper is usually used for food packaging (such as aluminum foil paper tray). It is used to grill food like bean sprouts and sweet potatoes at a barbecue to avoid burning. Sometimes used for decoration. Modern aluminum foil paper is made of aluminum and can also be used as an aluminum electrode for electrolysis. There are also hair stylists who use perm foil to perm for guests. Some people also use aluminum foil to absorb the oil in the soup. Aluminum foil is also widely used for the barrier layer, heat exchange, and as an electrical conductor. Typically, aluminum foil used in paper bag beverage packaging and food packaging is only 6.5 microns thick. This thin aluminum layer is water resistant, savory, anti-bacterial and anti-fouling.

  The other type of aluminium foil packaging, aluminum foil bags, are used as tin foil bags, pure aluminum bags, just called different methods. Aluminum foil bags are suitable for a wide range of applications. Aluminum foil bags have strong barrier properties, anti-oxidation, water resistance, moisture resistance, strong mechanical properties, high blast resistance and puncture resistance. The characteristics of strong tearing performance are favored by electronic products and food packaging industry, and the development momentum has been particularly rapid in recent years.

  Core features: 1, good moisture, light and air barrier

  2, good heat sealing, long shelf life, sealed tight.

  3, beautifully printed, clear pattern, attract attention.

  4, dust-free production environment, 100% ketone-free benzene ink production, perfect quality control system is the continuous quality assurance for your authority.

  With either type of aluminium foil packaging, the quality of aluminium foil is very important. Haomei supplies aluminium foil jumbo roll, aluminium foil for containers, household aluminium foil and aluminium foil for packaging of medicine, food, cosmetics etc. Welcome to send inquiries!

Why is aluminium foil paper sheet so popular

  The aluminum foil paper sheet is widely used in food, beverage, cigarette, medicine, photographic floor, household daily necessities, etc., usually used as its packaging material; electrolytic capacitor material; thermal insulation material for construction, vehicles, ships, houses, etc.; Silver lines, wallpapers, and various decorative labels for stationery and light industrial products. So why is aluminum foil so popular?

aluminium foil paper sheet

  Among the above various applications, the most effective performance of the aluminum foil sheet paper is as a packaging material. Aluminum foil is a soft metal film, which not only has the advantages of moisture-proof, air-tight, light-shielding, abrasion resistance, fragrance preservation, non-toxic and tasteless, but also because it has an elegant silver-white luster, it is easy to process beautiful patterns of various colors and The pattern is thus more popular with people. In particular, after the aluminum foil is combined with plastic and paper, the shielding property of the aluminum foil is integrated with the strength of the paper and the heat sealing property of the plastic, thereby further improving the shielding performance for water vapor, air, ultraviolet rays and bacteria which are necessary as packaging materials. , greatly expanded the application market of aluminum foil. Since the packaged article is sufficiently isolated from the outside light, moisture, gas, etc., 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.

  In recent years, aluminum foil paper has been quite prominent in architectural applications, and it has been attached to the surface of the thermal insulation material to make it more convenient, clean and especially beautiful. But the effect of different kinds of aluminum foil paper is very different, such as fireproof and ordinary is not a grade.

  In addition, aluminum foil sheet paper is light in weight, non-toxic and tasteless, and has the highest cost performance among similar products. Most importantly, aluminum foil is recyclable, which is an incidental feature that has nothing to do with the popularity of the industry, but indirectly contributes to environmental protection. Therefore, under the same conditions, we should give priority to the use of recyclable aluminum foil.
