Aluminum Foil for Packaging and Cooking
Aluminum flexible foil for packaging and household aluminum foil is two kinds of aluminum foils. 8021 is a main alloy of the household aluminum foils. What are the advantages of aluminum foil? Learn more.
Aluminum flexible foil for packaging has good ductility and dead-folding properties, and can meet different packaging requirements according to different shapes of food, thus showing flexible formability in packaging applications.
The ductility allows aluminum foil to easily adapt to various food forms. At the same time, the barrier properties are not affected by extension. The dead-folding feature makes it difficult to deform after the food is packaged.
In daily life, an example of how we make use of the dead-folding feature is: when we eat half of the chocolate and don’t want to continue eating, and the chocolate wrapper also uses aluminum foil, in order to prevent the chocolate from getting wet, we can re-fold the wrapper according to the shape of the chocolate. The folded wrapping paper will not rebound easily.
In fact, when aluminum foil was first invented, it was used by the Tobler chocolate factory in Switzerland to package products such as Toblerone chocolate bars. The barrier properties of aluminum foil packaging can prevent the chocolate from being exposed to water vapor.
At the same time, the good thermal conductivity also makes it difficult for the heat on the surface of the chocolate packaging to accumulate and heat up. Therefore, aluminum foil packaging can be said to be one of the ideal packaging for chocolate.
In addition, while aluminum foil is odorless, its good barrier properties can also prevent other odors from penetrating, which is very important to prevent chocolate from being tainted. Because the cocoa butter in chocolate can easily absorb other odors, the flavor of the chocolate itself is easy to be affected.
8021 aluminum foil, as one of the 8 series aluminum foils, is the most commonly used household aluminum foil. It is is mainly used in kitchen cooking and holding food. The surface of 8021 aluminum foil is extremely clean and hygienic. No bacteria or microorganisms can grow on the surface. It is a non-toxic packaging material that can be in direct contact with food without any danger to human health.
8011 aluminum foil contains Mn and Mg elements, while 8021 aluminum foil does not contain these two elements. Therefore, 8011 aluminum foil has high strength, but the corresponding elongation and puncture resistance in the same state are lower than 8021 aluminum foil.
The commonly used 8021 aluminum fol tempers are H14, H18, H22 and H24. 8021 h22 household aluminum foil refers to that it is work hardened by rolling then annealed to quarter hard. Welcome to leave message below to tell us your application and we will provide proper choice for you.
