Aluminum foil is a popular packaging material in the food and beverage, aviation, transportation, medical device and pharmaceutical industries. Due to its high ductility, it can be folded, shaped and easily rolled according to packaging needs. The inherent properties of aluminum foil allow it to be transformed into paper packaging, containers, tablet packaging, etc. It has high reflectivity and has applications in both decorative and functional areas.
According to reports, the use of aluminum foil around the world is growing at an annual rate of 4%. In 2018, global aluminum foil usage was approximately 50,000 tons, and is expected to exceed 2025 million tons in the next two years (that is, by 2025). China is the main user of aluminum foil, accounting for 46% of world usage.
Aluminum foil applications based on its properties
The most important application of aluminum foil is insulation. It acts as insulation in pipes and pipes, and in the construction industry it is used as a moisture barrier as a layer over insulating materials such as foam insulation and rock wool.
Aluminum foil is a very thin sheet that provides good protection against light and oxygen. Due to these properties, it is widely used in primary packaging of products sensitive to moisture, microorganisms and oxygen. It is one of the most popular packaging materials for beverages because it is more durable than other alternatives.
Application of aluminum foil in food industry
Aluminum foil is rapidly gaining popularity in food and beverage packaging and is expected to play an important role in the expansion of the industry. It is often used to package dairy products, candy and coffee. It is the safest option for food packaging and offers various benefits to the food industry:
·Extend food life
·Cheaper than other packaging materials
·Packaging size can be customized
However, aluminum foil is not recommended for salty or acidic foods. Aluminum tends to leach into foods in higher concentrations, in acids, salts, and liquid food solutions (such as lemon and tomato juice). These products may be harmed if they are stored in direct contact with aluminum ions. To get the benefits of aluminum without the risk of dissolving aluminum ions, use a composite film liner.
