Aluminum mirror sheet is the aluminum sheet processed by rolling, polishing and other methods to make its surface appear like a mirror. Many daily products are made of this polished aluminum sheet like electronic product shell, car decoration, luggage, signage, jewelry box,etc. Then, what makes a quality aluminum mirror sheet?First and foremost is the selection of the base aluminum material. The quality of the base aluminum material will directly affect the quality of the finished mirror aluminium sheet. There are generally two types of base aluminum materials: pure aluminum material and aluminum alloy material.Pure aluminum material has a high aluminum content, which can even reach more than 99%. The production technology is relatively simple and the cost is relatively low, so it has become a popular choice for the general industry.For aluminum alloy material, the preferred choice is with 3%-5% magnesium content. Its advantage is that the elongation and tensile strength are strong, and the weight is lighter than that of other aluminum alloy kinds under the same volume. Therefore, the mirror aluminum sheet made of this aluminum alloy is not only suitable for general industry, but also contributes to chemical, aerospace and other aspects.The next important step is grinding. After being cleaned and polished, the aluminum sheet will do grinding. During this process, all operation should be very careful, because all the defective products can only be treated as scrap aluminum.The following step is mechanical embossing. The equipment level has vital effect on the grades of the finished products. It is much simpler to roll and wrap the film. You just need to pay attention to the viscosity of the protective film and whether the adhesive remains after tearing off the protective film.These are some key parts influencing the quality of aluminum mirror sheet. With strict management, experienced worker and advanced manufacturing equipment, Haomei, a big aluminum sheet manufacturer ensures to offer you best aluminum mirror sheet with best price.

Mirror Polished aluminum sheet is the aluminum sheet processed by rolling, polishing and other methods to make its surface appear like a mirror.There are many types of aluminium mirror sheets, ranging from low to high, including common polished aluminium sheet, mirror anodized aluminum sheet and ultra-mirror aluminum.The common polished aluminium sheet is usually of 86% reflectivity, which is generally used in some relatively low decoration,but its decoration effect is still very good. The mirror anodized sheet and ultra-mirror aluminum is usually of 95% reflectivity, which is used in high-grade decoration. It is also used in some high-end electronic products and high-tech research.As a common buyer, how to test the quality of aluminium mirror sheet? After tearing off the protective film, touch the mirror surface with your fingers, the sweat stains on the fingers will remain on the mirror surface, but after wiping with a dry cloth or paper towel, the fingerprints will be wiped clean without leaving any traces. This is quality mirror anodized aluminum sheet.For common polished aluminium sheet, the left fingerprints can't be removed and will become more and more dirty with the wiping.Another testing method is to put a small aluminum plate on your ear to bend quickly. If you can hear a slight tearing sound, it is a mirror anodized aluminum sheet. Because the surface of mirror anodized sheet will have a layer of corundum-like oxide film, because the aluminum material itself is different from the oxide film structure, the oxide film will burst and emit a slight tearing sound during bending.

The stucco embossed aluminium sheet is calendered on the basis of the aluminum sheet to form various patterns on the surface. It has different thickness, patterns and specifications. There are also many aluminum sheet manufacturers. How to identify the quality and choose a reliable aluminum sheet supplier?There are three points for your reference:1. Check the gloss of the embossed aluminum sheet. Although the color is an external factor, it is closely related to its production process and quality control. If the color of the aluminum sheet is bright, its quality is generally better than that of poor color.2. Check if aluminum plate thickness is even. Some small factories can’t ensure uniform thickness of the aluminum sheets due to limited technology and equipment. Therefore, the thickness is is an important factor to test the quality of aluminium stucco embossed sheet.3. The casting process of stucco embossed aluminum. Generally, a professional aluminum sheet manufacturer adopt an integrated molding process to improve the yield and reduce the production cost while ensuring the superior performance of aluminium embossed sheet.In one word, as long as you pay attention to the above three points, your aluminum stucco sheet will not be poor. If you want to do bulk purchase with long term, on-the-spot investigation is necessary to ensure you have a reliable aluminum sheet supplier.

At present, the aluminum coil is a very popular cap closure material. It not only has beautiful outlook, but also has the function of pilfer proof. Therefore, aluminum ropp caps,aluminium screw caps and aluminium pilfer proof caps are widely used in the sealing packaging of beverage bottles, wine bottles, cosmetic bottles, medicine bottles, etc.Which types of aluminum coils are often used as cap closure material? Let's come to know the main three kinds.8011 Aluminum Coil8011 aluminum coil is a main material of the aluminium pilfer proof caps. In addition to the good deep-drawing performance, 8011 aluminum coil has a certain strength after processing and hardening, making it more suitable for bottle cap materials.8011 H16 medical bottle cap material and wine cap material are still slightly different in the production process. Because wine cap stretch requirements are higher than drug caps, there are differences in annealing.1060 Aluminum Coil1060 aluminum coil as cap closure head is in the form of aluminum-plastic combination. Because the aluminum-plastic combination part will contact the liquid in the bottle, most of them are used in the cosmetics industry, and some are used in the pharmaceutical industry.Aluminum Coil 5052The main alloy element of aluminum coil 5052 is magnesium, which has good forming processability, corrosion resistance, weldability, and medium strength. It is an main material for can lids.The aluminum coil 5052 is also mainly used for low load parts that require high plasticity and good weldability, such as mailboxes, gasoline or lubricating oil pipes, various liquid containers and other small deep-drawing small parts working in liquid or gaseous media.For these popular aluminum coils, Haomei has complete sizes and thickness, welcome to contact us for the cheap price.

Aluminium foil(or aluminum foil) is aluminium prepared in thin metal leaves. Approximately 75% of aluminium foil is used for packaging of foods, cosmetics, and chemical products.When aluminium foil is used for wrapping or cooking food, most people will struggle to choose which side of aluminum foil sheet to use.Because of the manufacturing process, most of aluminum foil roll is with one bright side and one matte side. There is only a small difference between the two, and there is not much difference in daily life.But if you really want to get a better effect, there are two tips for you. The reflectance of the dull side is 80% and that of the shiny side is 88%, so you had better use the shiny side to wrap food, which will speed up cooking.If you only store food in aluminum foil, the better way is to use the dull side to wrap food for some food may stick to the shiny side.There is also another aluminum foil paper, of which both sides are shiny. During single sheet rolling, the upper and lower surfaces of the aluminum foil are in contact with the rolls, and both sides have a bright metallic luster. If you buy this aluminium foil wrap, you won't have choice difficulties.

| Is It Safe To Cook Food In Aluminum Foil |

Is it safe cook food in aluminum foil?This question is just like another question: is it safe to walk on the street. It doesn’t have an absolute answer. We should understand: no food packaging is completely safe. The key is how to use.To ensure people's safety, aluminium packaging for food is produced in full accordance with food safety requirements. Food grade aluminum foil is clean, hygienic and resistant to high temperature because of high melting point. Therefore, no matter storing food in aluminum foil or heating food in aluminum foil, it will keep the original taste of the food.Aluminum foil paper is a relatively safer packaging material compared with others such as tin paper. Then where does the insecurity of aluminum foil food packaging come from? It is a cognitive error.The effect of aluminum on the human body actually refers to free aluminum ions. For example, alu used in water will ionize and produce aluminum ions. Then the aluminum ions will react with hydroxide ionized by water to generate aluminum hydroxide. If such aluminum ions are taken in excess ( the excess is not easy for ordinary people), it will do harm to our body.The melting point of aluminum is 660℃, far exceeding the temperature of most domestic ovens, and will not melt during use. Therefore, aluminum ions do not precipitate only by heating.In addition, aluminum is a very active metal, so it is easily oxidized by oxygen in the air to produce alumina under normal temperature and pressure. Alumina is a dense protective film that can prevent some substances from further corroding aluminum. In particular, foil packaging for food are all coated, and they will not cause any chemical action in the air, so they are very safe to use.But there is one point we should pay attention to. When we aluminum foil for barbecuing or wrapping food, we should not add acid substances such as vinegar and lemon. Acidic substances will precipitate the aluminum ions of the aluminum foil paper and can be easily mixed into food and then absorbed by the human body, which will cause aluminum poisoning. The aluminum can cause dementia. If a kidney patient consumes too much aluminum, anemia can occur.From the above information, it is not difficult to conclude it is safe to cook food in aluminum foil without the participation of acidic substances.

Aluminum foil for food is usually are double zero aluminum foil and single zero aluminum foil,that is, light gauge foil and medium gauge foil. In terms of performance, the requirements are mainly for tensile strength and elongation.With high elongation, stamping is not easy to crack. At the same time, it is required to be free of oil and odor to ensure that it meets the requirements of food packaging. The most commonly aluminum alloys and tempers are 8011/H12, 8011/H24, 8011/O, 3003/H24 and 8021 aluminum foil.8011 Aluminium Foil Food PackagingAs a food grade aluminium foil, 8011 aluminum foil is a commonly used material, especially for food packaging. The use of 8011 food foil prevents food from being affected by harmful substances in plastic bags for a long time.The egg custard cup aluminum foil is mostly 8011 aluminium foil food packaging. The common tempers are H18 and O. 8011 aluminum foil for food is free from oil and pinholes and easy to process. When it is used to make custard cup, it is not only easy to shape, but also can be fully automatically produced. For consumers, it is safe an Eco-friendly.8021 Aluminum Foil Paper for FoodThe surface of 8021 foil paper for food is extremely clean and hygienic. No bacteria or microorganisms can grow on the surface. It is a non-toxic packaging material. It can be in direct contact with food without any danger to human health.In addition, 8021 aluminum foil for food is an opaque packaging material. It is a good packaging material for products that need to avoid sunlight. For example, the packaging for butter is usually 8021 aluminum food foil packaging.

Aluminum foil, also called aluminum foil paper, is made of flattened metal aluminum. It is mainly sued for cooking in the kitchen, food packaging, food container,etc. Hundreds of thousands of tons of aluminum foil are used worldwide as the package of food, cosmetic, cigarette and chemicals.Different applications have different requirements for the thickness of aluminum foil. According to the thickness, aluminum foil can be divided into heavy gauge aluminum foil and light gauge foil.Heavy gauge aluminum foil refers to the aluminum foil paper with the thickness of 40 btm. heavy gauge aluminum foil will withstand a lot of wear and tear. Because of its high level of puncture and tear resistance, it is often deemed as the perfect material for more heavy duty applications.Light gauge foil is the aluminum foil with the thickness less than 40 ltm. It is generally used in flexible packaging including tobacco, food packaging etc and related industries. We also offer a world class double zero graded foil which enables PE coating on this Light Gauge Aluminium foil.How to find the thickness of aluminum foil? It is difficult, but not impossible, to measure the thickness of such a thin material, and impossible to do with common measuring tools, like a ruler or a measuring tape.Remind yourself of the relationships density = mass ÷ volume and volume = length x width x height. When working out the thickness of aluminum foil, you are simply working out its height dimension. This simple formula allows you to measure the thickness of aluminum foil.
