Weeks ago the Trump administration declared to take double taxes on China aluminum foil exported to America. Owing to the “fact” that low price China foil has squeezed too many small American companies out of market, the Business Department decides to take anti-dumping and countervailing duties against foil from China. This means the highest tax rate may reach 186%, which will make any possible importers flinch back.
It’s said that in 2017 China export of aluminum foil was 1,163,000 metric meters, and in August, when the first verdict against China of America government was made, local companies canceled many orders involved. There is no doubt that China export of aluminum foil to America will greatly reduce in the next months, but influence of the final verdict on whole export statistics will depend on demand state of other countries.
Aluminum foil containers are very popular these days. It’s not exaggerating to say that they make our life quicker and more convenient. Decades ago, the words “fast food” came into fashion, which was followed by prosperity of relative additive products, including plastic bags, paper bags and aluminum foil containers. The last proves to be the perfect one. Plastic bags are considered to give off toxic elements while containing food of high temperature and paper bags are too vulnerable to liquid food or heavy food. Owing to the fact that aluminum foil containers show good strength which can compete with plastics, some people worry about whether it is safe to use them.
It’s understandable to have such doubts since food safety remains to be a global problem. As a matter of fact, aluminum foil containers are safe to use with several surprising advantages. First, they show good water proof effect. Paper bags become destroyed once in contact with liquid, but aluminum containers can last for a long time as long as they are not torn. No matter you use them to keep frozen food in fridges or contain soup for your lunch, you needn’t worry about their strength. Second, they have excellent bacteria insulation property. Many people believe that metal containers are not safe because you may take in metals with food. Aluminum is different from other metals in this respect. It obtains strong protective layers after proper process onto the surface. Therefore, aluminum foil containers neither contain nor produces toxic elements. Third, they show extraordinary adaption to temperatures. You can put them into baking ovens or fridges without worrying about safety problems, but the pre-condition is that you should keep them well.
Aluminium foil bags are usually made first by hot rolling or cold rolling of aluminum pigs, normally 1xxx or 8xxx, and then by punch forming of rolled materials.
Aluminium foil bags are so universally applied because they overshadow other packaging materials in several crucial aspects. First, they are nontoxic. Some other metals either contain or produce harmful and even poisonous materials under given circumstances. Aluminium is one of the rare exceptions. Its ions are so active that they have chemical reaction quickly with oxygen in the air, during which process a layer of protective film is produced. This film, of little activeness, still remain intact in severe natural environment. Further more, neither the film nor aluminium itself contains or generates any toxic bacteria. Second, aluminium foil bags, usually made of aluminium foil and plastics, are both strong and extensive. It’s not easy to break them by pulling or tearing, yet they are soft like a piece of paper. Easy to fold, they prove to be excellent packaging materials of flexibility. Third, based on the two advantages, they perform extraordinary sealing effect. Fourth, they are environmental. They can be cooked with food without deformation. Once discarded, aluminium foil bags can be recycled conveniently, not producing any pollutants.
Aluminium foil bags covers a wide range of application in our life. First, they are containers for facial masks. Just imagine how many girls using facial masks there are in the world, one will be astounded at the huge consumption number of aluminum foil bags every day. Second, they serve to be bags for nuts and dried fruits. Small bags of peanuts, pistachio nuts, dried currants or kiwi fruit are many girls’ favorite snacks over a movie in front of the computer at night. Third, they also contribute to packaging of food for old people and children. Milk powder is kept in aluminum foil bags to prevent moisture. Cooked meat last much longer if stored in vacuum tight bags.
Aluminum foil is obtained by pressing aluminum alloy into thin pieces. Because of its softness and good sealing effect, aluminum foil is widely applied in packaging, heat insulation and decorative materials, among which packaging best embodies its advantages.
Aluminum foil wins popularity for several reasons. First, it’s soft and moisture resistant. This makes it particularly suitable to be used as packaging materials. Second, unlike some other metal materials that contain toxic elements, it’s nontoxic and of good wear resistance. Even if applied to daily items, it’s healthy and environmental. Third, it’s convenient to print colored designs and pictures based on its graceful silver surface, which strengthens its decorative function. Fourth, when compounded with other materials like, aluminum foil shows better strength, heat insulation, water-proof ability and anti-corrosive property. Cooked food wrapped by this kind of foil lasts over a year without going bad. Besides, it’s convenient to cook wrapped food and then open the package to eat.
With economic development and increasing demand for fast food, the application of aluminum foil is more and more widened. These days people attach more importance to appearance. They tend to believe that there will always be noble souls under attractive appearances. Beers and beverages of medium quality, if matched with aluminum seal and package, sell at a good price. Can food is contained in aluminum foil cans to keep freshness and extend guarantee period. Modern rolling mills can produce aluminum foils of larger width, thicker rolls, rapider speed and more advanced automation. The width of a roller can reach as much as 2200mm and above. The speed of rolling is 2000m/min and more. The weight of a single roll of foil is at least 20 tons. Most rolling mills are equipped with automatic system like AGC and AFC.
As a widely applied food container, aluminum foil tray can be obtained through cold or hot rolling of 3003 or 8011 aluminum pigs. In accordance with different standards, it can be classified into flat & wrinkled types, disposable & reusable types and plain & coated foils. It’s featured by smooth surface and excellent packaging function.
Aluminum foil trays are universally used in air food packaging, domestic cooking and cake wrapping in large bake houses. Many people are not familiar with air food, but the latter two are not novel to them. Dough of small cakes are usually put in little silver cups and then into the oven. A few minutes later you draw the board out with hot small cakes on it. It’s also convenient when you have the cakes, for you just need to hold the tray and pull the cake out with your teeth. Some white collar workers in China like cooking food in the evening and bringing it to the company for lunch of the next day. They have to heat it up again in the micro-wave oven before eating the lunch. Some put the food in plastic food containers, which are not a good choice because plastics, once heated, is harmful to health. A better choice is thinner and cheaper aluminum foil tray. It withstands high temperature and is nontoxic.
As a matter of fact, with increasing need for fast food, aluminum foil trays are winning more and more popularity. It seems that there will be no substitute for them in short future, because they boast obvious advantages. First, they are light and safe. With a density much smaller than other metals, aluminum products are almost the lightest of all metal products. They can withstand both low and high temperatures without deformation or change of properties. Unlike some toxic metals, they neither contain nor produce poisoning materials even under sever conditions. Food can be cooked directly in aluminum foil trays and will not lose its original appearance or taste. Second, they have extraordinary barrier property and heat maintaining performance. If thick enough and sealed well, an aluminum foil tray is able to keep air, water and even radiation completely outside. Third, they are environmental. Either disposable or reusable trays are suitable to be recycled, during which no pollutant or harmful material will be generated.
