How much is the cost of aluminium foil

  The cost of aluminium foil is relatively stable, although it’s influenced by aluminium ingot price, currency exchange rate and shipment cost. The impact of the factors above is smaller in comparison to process methods and raw material type of the foil.

aluminium foil rolls

  Harga aluminium foil of 8011 rolls ranges between $2750 to $3000 per metric ton. The minimum ordering quantity is at least 2 tons, and some suppliers make it 5 tons. It can be used in medicine packaging, food packaging, lunch box material, tape foil, cable foil, milk cover material, bottle cover material and many other fields. Among our hard-core products, 8021 aluminium foil boasts excellent insulation of moisture, light and heat, used more frequently as a raw material for composite products. 8021 aluminium foil cost is higher than 8011. We have both rolls of thickness from 0.019mm to 0.2mm, and width from 100mm to 1650mm.

  In comparison to 8011 and 8021, 8079 aluminum foil displays a higher strength and better elongation. In addition to its advantages like moisture-proof, airtight, light-proof, wear-resistant, fragrant, non-toxic and tasteless performances, it is easy to process beautiful patterns and patterns of various colors on it, which helps it win more popularity. 8079 aluminum foil is widely used in food packaging, medicine packaging, battery soft package and other fields. As a result, the cost of aluminium foil 8079 is higher, too.

Household and food grade aluminium foil

  Household aluminium foil and food grade aluminium foil are not the same thing. Household aluminium foil rolls are definitely of food grade, but food grade rolls are not necessarily household ones. By household we mean kitchen or used at home directly.

Household and food grade aluminium foil

  Food grade aluminum foil is free from toxic elements like heavy metals, and its surface is clean without rolling oil after being annealed at high temperatures. It’s further divided into household and packaging aluminum foil. The former is made of 8011 aluminium alloy, with a thickness between 0.015mm and 0.02mm, and width from 300mm to 450mm. Household rolls spotted at shops are usually small, weighing only less than 2kg, packed in a cardboard box. These, however, are not what Haomei Aluminium supplies. We usually get in contact with clients from overseas who purchase rolls with a weight no less than 20kg and cut the rolls into parts of shorter length and small width. The cut parts are eventually rolled into smaller rolls and placed in cardboard boxes sent to super markets. There’s no need to worry about safety problem of 8011 aluminium foil for household use from China, for most of our products are exported to America and Europe.

  Packaging aluminum foil is the other important use of food grade aluminum foil. It’s used to package food. The world’s food industry is in an important period of vigorous development. The emergence of aluminum foil for food packaging has greatly improved the level of food processing and accelerated the modernization of people’s diet. There are two main applications of aluminum foil in food packaging: one is aluminum-plastic or aluminum paper composite packaging; the other is aluminum-plastic paper multilayer composite packaging. China’s food aluminum foil demand is about 30,000 tons / year. Haomei Aluminum is a large-scale manufacturer of aluminum foil raw materials for food packaging. The raw materials of aluminum foil for food packaging are mainly 1 series, 3 series and 8 series products, mainly including model numbers 1060, 1100, 3003, 8011, 8021 and so on. According to the needs of the packaged food, the softness and hardness of the alloy is selected, that is, the alloy state. The commonly used states are H14, H16, and H18.

Is it safe to use aluminium foil packaging material

  Nowadays aluminium foil packaging material has become ubiquitous in various industries. Even people who leads the simplest life can not have avoided using products packed in aluminium foil. Packaging aluminium foil hold toothpaste, facial cream and mini cakes hot from the oven. We have got quite used to them. The application of aluminium foil for packaging in food industry has a history of over a century. Despite this, a question keeps haunting us even today: is it safe to use aluminium foil as a packaging material?

aluminium foil packaging material

  The answer is positive. Tests show that packaging aluminium foil is free from potential health problems of heavy metals, ethanol, oil or paints. The currently adopted aluminum foil composite technology in China has filled in the domestic blanks of similar technologies, reaching the highest level in international market. Made by the high barrier polypropylene composite technology, the PP film on the inside of aluminium foil packaging materials can effectively isolate the food from the metal sheet, which has a high degree of hygiene and can effectively extend the preservation time of the food. Food packaged in such a material does not change color or taste. In addition, the use of aluminium foil for packaging attributes a lot to environmental protection. The packaging materials can be recycled in a more environmental way than plastics. Food containers such as metal cans and boxes made of aluminum foil have the characteristics of light weight, zero rust, and high food preservation safety, widely used in packaging of device paste food, sauce food, and wet and dry canned food, including paste, cream, tomato sauce, chili sauce, apple sauce, peanut butter, canned fish and various meat canned foods.

  Haomei packaging aluminum foil, all made of domestic raw materials, helps to save more than 50% of the raw material aluminum compared with the traditional process, which greatly reduces the product cost and provides a price advantage for your products. Safe, light, hygiene, convenient and environmentally friendly, aluminum foil packaging materials will replace tinplate food containers and become a new upgraded product in the packaging industry.

Aluminium foil properties

  Aluminium foil properties include high cleanness level in surface, nontoxic material, excellent insulation effect, good plasticity, poor resistance to tearing force and high possibility in reacting to certain metal materials. In detail, aluminum foil has the following properties.

  (1) The surface of the aluminum foil is extremely clean and hygienic. No bacteria or microorganisms can grow on the surface.

  (2) Aluminum foil is a non-toxic packaging material, which can be in direct contact with food and you are exempt from any worries that it may endanger your health.

  (3) As an odorless and odorless packaging material, aluminium foil rolls will not make the packaged food have any odor.

  (4) If the aluminium foil itself is not volatile, it and its packaged food will never dry or shrink.

  (5) No matter at high or low temperatures, aluminum foil rolls will not have the phenomenon of grease penetration.

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

  (7) Aluminum foil has good plasticity, so it can be used to package products of various shapes. Various shapes of containers can also be arbitrarily formed.

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

  (9) The aluminum foil itself cannot be heat-sealed, and it must be coated with a heat-resistant material, such as pe, to be heat-sealed.

  (10) When aluminum foil comes into contact with other heavy metals or heavy metals, there may be adverse reactions.

Aluminium foil for cooking

  Aluminium cooking foil, also called aluminium foil for cooking, is a piece of paper made of flattened metal aluminum. It is mainly used for food cooking and containing in the kitchen or for making simple and clean materials. Hundreds of thousands of tons of aluminium foil rolls are used worldwide to protect and package food, cosmetics and chemicals. Most aluminum foil is shiny on one side and dull on the other. The aluminum foil paper used for cooking can wrapped on both sides of the food. Generally, it is recommended to wrap it with a bright surface to improve the heat transfer effect.

  Aluminium cooking foil is light in weight, good in ductility, and low in price, thus is a kitchen standing product widely used in daily life. Aluminum foil has bright and matte surfaces. The matte side takes in heat and you need to make it to face the heat source in cooking, and the bright surface can reflect the heat energy, and you can wrap the ingredients with the bright side inward for cooking. Some foods (eg sweet potatoes, edible mushrooms, etc.) must be wrapped in aluminum foil to avoid burning. Seafood and oyster mushrooms are also cooked in aluminium foil to retain their flavors.

aluminium foil for cooking

  Another use of aluminium foil for cooking is in the oven. Round ingredients such as pineapple bread and small meals are wrapped in aluminium foil before being fed into the oven, for they are prone to scorch with the inner unheated if these food materials are directly baked in the oven. Wrapping them with the bright side inward, since the heat conductivity of this side is better, can have foods heated evenly inside and outside. In the baking process, the heat source of the oven is transmitted to the aluminum foil paper and then to the food, so that the food and the aluminum foil paper are sealed in the sandwich to generate water vapor and hot air, and the food can be evenly heated.

  The household aluminium foil has a use unrelated to cooking in the kitchen. As known to all, after the ginger and garlic are put on the grinding plate and ground into mud, residues are always stuck in the small hole of the grinding plate, which is troublesome to clean and easy to cut hands. Here if you have a piece of aluminum cooking foil laid on the grinding plate with the bright side facing upwards and then ground these ingredients on it, the problem will be solved. The aluminum foil is well-shaped and flattened on the grinding plate. The convex part of the grinding plate will make the aluminum foil have sharp edges and corners, which is very convenient for grinding mud.

  Haomei supplies industrial aluminium foil 8011, 8021, 8079, 1060, 1070, 1100, 3003, 3004, 1235 and 5052. Welcome to send inquiries!

What is heavy duty aluminium foil

  Heavy duty aluminium foil is named in opposite to Regular aluminium foil. The words “heavy duty” does not implies a higher tax as some people might imagine, since Trump has been taxing aluminium foil from China heavily recently. As the name implies, heavy duty aluminium foil simply refers to a kind of aluminum foil that is thicker, sturdier and thus heavier than regular aluminum foil.

heavy duty aluminium foil

  Both regular and heavy duty aluminum foil are made of the same material: aluminium. The difference lies in their thickness. Thin aluminium foil rolls are only 0.006mm thick, yet thick ones can be up to 0.2mm thick. That’s like the height difference between a newly born mouse and a human giant. Correspondingly thicker aluminium foil has a much heavier weight, which results in directly a higher price per area unit. A 200-square-foot roll of Reynold’s Wrap Aluminum Foil costs $9.19 on Amazon. For roughly the same price ($8.99), you’ll get a 130-square-foot roll of Reynold’s Wrap Heavy-Duty Aluminum Foil.

  Then which one to choose? Regular of heavy duty aluminium foil?

  It all depends, actually. Regular aluminum foil will definitely work for kitchen tasks like covering dishes to be stored in the fridge, wrapping sandwiches and other foods, and lining baking sheets. But regular foil doesn’t hold up as well with heavy foods or with high-heat cooking on the grill, where it’s more likely to tear, rip, or break. While heavy duty aluminium foil is 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. In a word, you need to choose based on your actual needs. You can just try both and then judge by yourself, since everyone has his or her own cooking habit.

Does aluminum foil rust?

  Does aluminum foil rust?

  This question keeps emerging on sorts of Q&A platforms, which demonstrates people’s eagerness to have an answer. Here we hope to offer what you just need.

  Before getting to the answer, we need to clarify the concept of “rust” first. Rust is a chemical process during which metals get oxidized after being exposed to the air that is full of oxygen, yet this is not enough, for the word usually indicates a state of “decay” of a metal on the surface. Take iron for example, dark brown powder covers the surface of an oxidized iron and falls off under slight exterior forces like wind, rubbing or vibration. This means that the outer layer of iron is ripped away to form ferrous oxide, and because it is porous, oxygen can continue to penetrate to the iron, creating more rust. Eventually, the entire iron object will be converted to rust. Most metals rust in the same way, except for rare ones like aluminium whose oxide is a solid layer attached firmly onto the surface of an aluminium piece. Therefore, aluminium oxide can not be called something like decay in a strict point of view.

does aluminum foil rust

  But if you mean “oxidize” by “rust”, then aluminium foil is likely to get rust soon after being placed in the air. Some metals are more reactive than others and Aluminum is far more energetic to oxidize than iron. The roll of aluminum foil you get in the store is already rusted before you use it.

  So why does it still look shiny? Aluminum forms aluminum oxide. This is an extremely hard material that forms a layer on the surface that is only a few molecules thick. It then prevents more oxygen from getting to the pure aluminum below the oxide layer. Thus if you mean “decay” by “rust”, then aluminum does not rust. It only get oxidized. Magically, the oxidizing process makes it more “corrosion resistant” in a way.

Aluminium foil manufacturing process

  The aluminium foil manufacturing process consists of smelting, rough rolling, intermediate rolling and aluminum foil blank rolling.

  Smelting

  Aluminium ingots are placed into the furnace to get smelted, and aluminium liquid flows into the casting mill through the launder, during which the the refiner A1-Ti-B is added to form a continuous and uniform refining effect. Gases and slags get removed constantly and uniformly by the graphite rotor.

  Rough Rolling

  The aluminum liquid from the first step becomes a billet. The temperature of inflow water in the inner cavity should be kept between 20 and 23 degree centigrade, and that of outflow water between 28 to 32 degree centigrade. The static pressure of the aluminum melt between the rolls is controlled at 0.004-0.005mpa, so as to ensure that the crystal direction {100} of the material is more than 95%, the grain size is less than 5um, and the slab of 6.5-7.5mm is rolled.

aluminum foil manufacturing process

  Intermediate Rolling

  The above slabs are rolled again by cold rolling mill. When the thickness reaches 4.5mm, they are sent to the annealing furnace. After heating to 360 ℃ and holding for 2 hours, they are continuously heated to 580 ℃ and holding for 18 hours. Homogenization annealing is carried out to make the grain size uniform and consistent in direction. Then, the slabs are continuously cold rolled to 0.60mm in cold rolling mill and sent to annealing furnace again, heating to 460 ℃ and holding for 5 hours. When the they cool down to 400 ℃, have them heat preserved for 7 hours to conduct intermediate annealing, and then continue rolling them to 0.3mm thick.

  Aluminum Foil Blank Rolling

  This step uses the four roll irreversible foil rolling mill to roll the above 0.3mm aluminum foil blank into the finished aluminum foil product.

  The aluminium foil manufacturing process above is short and cost efficient. It enables you to produce ultra-thin aluminum foil of advanced level with a small investment scale. Compared with the hot rolling production process, the investment cost is reduced by two-thirds and the operation cost is reduced by more than half.
