12mciron thickness and 8011 alloy catering foil

  12mciron thickness and 8011 alloy catering foil is of 0.012mm thick, 8011 aluminium grade and usually O state. Other tempers include F, O, H14, H16, H18, H19, H22, H24, H26 and H28. The heaviest thickness of 8011 foil reaches 0.2mm, but thick foil rolls are usually made into food containers and sealing caps. Those used for catering is almost the thinnest of all, for softness and cleanness are more important than thickness here.

12mciron thickness and 8011 alloy catering foil

  As a regular catering foil, 8011 aluminum foil contains 0.05 to 0.90 share of silicon, 0.60 to 1.0 iron, 0.10 copper, 0.20 manganese, 0.05 magnesium, 0.05 chromium, 0.10 zinc and 0.08 titanium. It has a tensile strength between 125 to 165, yielding strength 110 and elongation 2 to 5. 8011 is made into aluminium foil because of its excellent properties. Cleaner than industrial pure aluminium of 1000 series, it shows better tensile strength as well. That’s why it can be made as thin as 9micron. Thin as it is, it does not breaks unless torn fiercely in a particular direction. It’s convenient and efficient to print on the foil, which extends its application to vast packaging industries covering all packaged food related areas.

  8011 alloy catering aluminium foil has two sides. One side is bright and the other is darker. The bright side is called the sensitive side, and the darker side is called the matte side. When we use it, the matte side is expected to contact food, and the sensitive side is exposed outside. Wrong operation might lead to food adhesion on the aluminium foil paper.

Reasons for aluminium foil as packaging material

Aluminium foil is used as a packaging material because it’s light, tensile and insulating.

Aluminium has a very small density, the smallest of copper, iron and aluminium. A piece of aluminum sheet of 9micro, for example, weighs only one third of a 9mc copper sheet of the same area. Meanwhile aluminium boasts an excellent tensile strength, which makes it possible for aluminium manufacturers to stress thick aluminum sheets into foils as thin as 9um. Owing to the fact that metal products are usually sold by weight, aluminum foil roll jumbo proves to be an overwhelming raw material for packaging in this regard.

In addition, aluminium foil rolls display an outstanding insulation to heat, air, light and moisture. This helps to extend shelf life of foods packaged by it. Opaque as the foil is, no light is able to penetrate through to damage the food. It acts like a well-armed protector.

Many people worry about safety problem of aluminium as packaging material, questions about which never disappears on quora, but up to now, there is no scientific evidence proving real harm to human health of aluminium packaging. The so-called “excessive taking in” of aluminium is based on a ridiculous number. However, it’s understandable if you are worried, since no one can prove that aluminum packaging is totally healthy, either. Therefore, you are advised to buy aluminum-packed foods of trustworthy brands who will use good quality foil rolls rather than inferior ones.

Is aluminium foil safe for baking

Is aluminium foil safe for baking? People keep asking similar questions in spite of the fact that they are given positive answers. Aluminium foil for baking is usually hardwood and of multi-roll type packaging. The main components of the foil is 8011 aluminum, the content of the foil is about 50%, the standard of China is defined as “Precision foil”. For aluminium foil for baking, the toxic elements are as follows: 0.01%, cadmium: Unusual 0.01%, arsenic: Unusual 0.01%. The reason is that the most suitable foil is used and its content is set by the national standard.

When you use baking aluminium foil, do not use cooking flavors or lemons, so that acidic substances, such as metal foil and foil, takes out metal deposition that might later be absorbed by human body in contaminated food. Aluminium stimulates stomach and is even believed to cause dementia. People with kidney illness may lack in blood after taking in excessive aluminum. In baking those foods, greens are a good substitute. Food can be wrapped in coconut green leaf, tama rice leaf, or green leaf, which are non-staining and healthy.

How to wrap food in aluminium foil

How to wrap food in aluminium foil? The aluminium wrapping foil is divided into glossy surface and matte surface. The glossy surface can better absorb external heat and help food to be heated evenly. When you wrap food, the matte surface should be in contact with food, so that the heat is evenly distributed on the surface of the food, shortening the cooking time.

Aluminum foil has the functions of heat preservation, waterproof, sealing and conduction. In addition to helping food to be evenly heated and preventing food from scorching during cooking such as grilling and baking, it can also play a role in cold storage, sealing, heat preservation, and separation of heat sources. It is also indispensable for barbecue in the wild.

In addition, some meat dishes are prone to oil fume or scorch during cooking. Aluminum foil wrap can also solve the problem and avoid the generation of harmful substances. Tin foil is like a mysterious coat, which envelops the nutrients and moisture in the ingredients. The moment when the foil is cut with a knife, the aroma is tangy.

Aluminium wrapping foil paper can withstand high temperatures of about 400 to 600 degrees Celsius, so whether it is boiled, oven or charcoal roasted, there is basically no need to worry too much about the risk of elution of heavy metals.

Is aluminium foil safe to wrap food? Yes. However, the Food and Drug Administration reminded that acidic materials will erode the aluminum wrap foil. It is recommended that the ingredients be cooked and removed before adding acidic substances such as vinegar, lemon, tomato sauce, etc. In addition, if the surface of the aluminum foil is scratched, it is recommended to replace it with new products.

Is aluminium foil safe to wrap food

Aluminum foil rolls are light, shiny, strong in reverse ability, good in barrier properties, strong in adaptability to temperature, stable in shape at high or low temperatures, strong in light-shielding, and excellent in fragrance retention. That is why is aluminium foil used to wrap food. However, many people still have doubts about safety of aluminum foil for food wrapping. Is aluminium foil safe to wrap food, anyway?

In the first place, aluminum foil can not be used to wrap some foods containing ingredients that will definitely not work if they react with aluminum, although the surface of the aluminum foil is indeed treated with an oxide film to protect it. Aluminum is an easily oxidizable metal. It has an oxide layer on the surface of the aluminum foil, so that the aluminum ions are tightly fixed by the oxide layer, so that it cannot escape; it further improves the safety of our use of aluminum foil. But keep in mind, try not to touch the aluminum foil or aluminum with strong acid items, because the acid will destroy its oxide layer.

Second, aluminum foil packaging and wrapping has been popular for half a century in many countries in Europe, America, the Middle East and other regions. It has also been widely used in many industries such as domestic aviation, hotels, and West Point cooking. Its worldwide user population is very large. In addition, China, as a major exporter of aluminum foil products, also has world-leading technology in the aluminum foil packaging industry. The products it produces are fully in line with national food packaging safety.

Finally, as emphasized by many scientists, “No food is absolutely safe, and no food is free of any hidden dangers.” At present, it seems that no authoritative institution has experiments to prove that aluminum foil does harm to the human body. The so-called negative effect of aluminum on the human body actually refers to free aluminum ions. For example, the alum used to make rice noodles into rice noodles also becomes aluminum hydroxide. If such aluminum ions are taken in excessively (note that the precondition is excessive dosing , which is not easy for ordinary people to reach), they will cause certain health problems.

So rest assured. Wrap beef and vegetables with aluminum foil as much as you like at a barbecue. Believe in science and practice, don’t scare yourself.

Why aluminium foil is used to wrap food items

An aluminium foil is used for wrapping food because its performances fully meet the requirements of food packaging, the ultimate goal of which is to extend a food’s shelf life as long as possible. To achieve this, the food must be kept from possible negative materials like light, moisture, micro organism etc.

Aluminium foil is used to wrap food items

The aluminum foil are just up to the mustard. As a pure metal product, it’s opaque and nonporous, keeping either light or water gas outside while being used to wrap food. In addition, the aluminium metal is endowed with a natural corrosion resistance. Few of the corrosive materials are capable enough to pierce its defense line to reach the inner side. In this way, bacteria and viruses are kept off.

Aluminum foil itself is sanitary enough, neither emitting nor attracting detrimental elements. The inside of food packaging aluminum foil made to be as smooth as possible, in order to reduce possibility of damages from friction between the foil and wrapped foods.

Because of its advantages above, an aluminium foil roll is used to wrap food items like chocolates, cooked beef, liquid milk, to be baked mini cakes and so on, playing an irreplaceable role in our daily life.

Food aluminium foil roll production process problems

Many problems might rise in the aluminium foil production process, among which are thickness difference, water marks and oil remains. Here we deal with the three.

The thickness difference of aluminum foil rolls is often encountered in the rolling process of aluminum foil production. 3% thickness difference may be easy to achieve in aluminum plate manufacturing, but it is very difficult in aluminum foil production. Because the thickness of aluminum foil is very thin, such as drug foil, i.e. medical aluminum foil, the thickness is usually 0.02mm-0.025mm, many fine conditions will have a serious impact on it. Such as temperature, oil film, oil and gas concentration, etc. The length of a roll of aluminum foil can reach tens of thousands of meters, the rolling time is long, and it is easy to cause the uneven thickness. The only way to adjust the thickness is the tension speed. Therefore, it is very difficult to control the thickness difference of aluminum foil within 3%, and the requirements for equipment and environment are very strict.

aluminium foil roll

A water mark refers to the water drop on the aluminium foil food before rolling. After rolling, some white spots will be formed. If the water mark is slight, it will affect the appearance and brightness of the aluminum foil surface. If it is serious, it may cause the ribbon of the aluminum foil. The first section of water mark is caused by the water drop in the rolling mill on the surface of aluminum foil or the water drop in the oil is formed in the rolling process. It is necessary to control the water content in the oil and keep the rolling mill clean and sanitary to avoid the water mark of food aluminum foil.

Oil remains are often encountered in the rolling step of aluminum foil production process, which means that there are some extra oil in the aluminum foil food after rolling, that is, oil other than rolling oil film. This kind of oil is complex and dirty. It is usually dripped on the surface of the aluminum sheet by the oil at the roll neck or at the outlet of the rolling mill. Oil pollution has a great impact on the quality of aluminum foil. Some aluminum is used as packaging or decoration materials, and the surface must be smooth and bright. Oil pollution will also affect the thickness of the finished aluminum foil roll. In the annealing process, it is easy to form bubble like bulge, and the oil pollution is relatively dirty, which will form a lot of residues and affect the use of aluminum foil. Oil pollution is a very important index to evaluate the quality of aluminum foil.
