With the development of the society, the aluminum foil is often used for the packing materials on the market. Why is aluminum foil used for wrapping or packing food? And why do we choose aluminum foil to make packing boxed or bags? Today, we will talk about it.
One of the most important reason why the aluminum foil is used for packaging materials is because of its properties of airtight and light-proof. The aluminum is easily oxidized by oxygen when it exposes to the air and the result of this chemical reaction is the formation of a layer of dense oxide Al2O3 protective film on the surface of the aluminum, which can prevent oxygen continue to oxidize the aluminium. So it can keep the air from entering the aluminum foil boxes or bags with the barrier of this dense protective film, which can prevent food from being oxidized and spoiled. As we all know, oxygen and moisture in the air can easily make food spoiled. Wrapping and packaging food with the aluminum foil would maintain the freshness and taste of the food. And the aluminum foil is opaque and has good light-shielding properties, preventing certain foods from discoloration or deterioration due to exposure to light.
Some foods, such as coffee beans and candies, are more afraid of moisture and the dispersion of flavors that will affect their taste. Aluminum foil paper is a special metal packaging paper that is airtight and light-proof, which can temporarily isolate food from the air. As we all know, a lot of moisture comes from the air. Once the humidity in the air is too high, it will cause food to absorb moisture. Use aluminum foil to temporarily isolate them from the air so that the food will not be affected by moisture. Even if it is kept for a longer time (the shelf life cannot be exceeded), they still can be sold normally.
There are many items in life that have their own special odors. When we place food and these items with special odors together, it is easy for the items to exchange odors with each other. This problem can be avoided by using aluminum foil. Aluminum foil can not only isolate the air, but also isolate odors to avoid odor transfer.
Aluminum foil is also often used in ovens because aluminum foil has good thermal conductivity and can quickly absorb and conduct heat. Using aluminum foil to wrap food in the oven takes advantage of the heat conduction properties of aluminum foil. Aluminum foil can dissipate heat evenly, allowing food to be heated more evenly without burning. It can also prevent the loss of moisture and nutrients inside the food, preventing the food from becoming dry and lacking the original freshness of the food. In addition, it is also to prevent the food and the baking pan from being bonded together when they are in direct contact, making it more difficult to clean later.
In addition, aluminum foil lunch boxes also use the thermal conductivity properties of aluminum foil. When food is put into an aluminum foil lunch box, the box will quickly absorb the heat of the food and conduct it to other parts of the box because of the thermal conductivity of the aluminum foil. In this way, the aluminum foil lunch box can effectively maintain the heat of the food, keep the food warm for a certain period of time, and prolong the deliciousness of the food. In addition, aluminum foil also has good high temperature resistance. High temperatures are inevitable during food processing and cooking. Aluminum foil lunch boxes can withstand high temperatures without deforming, releasing harmful substances, and will not bring an unpleasant smell to food, ensuring food safety. Therefore, using aluminum foil bags to package food can maintain the integrity and safety of food in high temperature environments, providing consumers with more reliable food safety protection.
Aluminum foil is also lightweight yet strong and has unique dead-fold properties, making it an ideal material for packaging and repackaging a variety of different products and product shapes. When the foil is pressed into the shaped disc, it remembers its shape, especially the placement of the creases and edges. Because aluminum foil is so malleable, it can easily deform without losing its barrier properties, making it an ideal material for home use.
Aluminum foil is also often used to make food packaging bags because of the above properties. And Aluminum foil is lightweight, which makes it convenient for packaging and transportation purposes. It reduces the overall weight of packaged goods, thereby lowering shipping costs and improving logistics efficiency. However, food packaging bags are not simply made of aluminum foil, but are made of composite materials. This composite material is made of aluminum foil and nylon. Some are made of four layers of co-extruded film. When packaging some foods, they are often made of multi-layer composite materials. The reason for using multi-layer composite materials is to package food and maintain the quality of the food. Another reason is that rich colors and patterns can be printed on food packaging bags. This is also a way for food to be recognized by the market, and it is also a way for food promotion.
