Different Forms of Food Grade Aluminum Packaging

Food packaging aluminum foil is an important market for food grade aluminum applications. QYResearch research results show that the global food packaging aluminum foil market size will be approximately 28.4 billion yuan (RMB) in 2022, and is expected to reach 41.8 billion yuan in 2029, with a compound annual growth rate (CAGR) of 5.6% during 2023-2029.

Due to its thin thickness and low strength, aluminum foil is generally not used as a packaging material alone, but is often used together with plastic, paper and other materials as part of composite packaging. In the field of food and beverages, common food packaging aluminum foil application types include: aseptic packaging, lunch container, stand-up bags, wrapping paper, sealing cover films, high-temperature cooking bags, etc.

Among them, aseptic packaging is a common packaging form for liquid milk and fruit juice drinks. It is generally composed of paper, plastic, and aluminum, so it is often called paper-plastic-aluminum composite packaging. Aluminum foil plays a barrier role, usually with a thickness of about 9μm (0.009mm).

Aluminum foil also has better food safety. Aluminum foil has high corrosion resistance in the pH range of 4-8.5 due to its dense oxide layer on the surface, while the pH range of many foods is 4-7, which is within the corrosion stability range of aluminum foil. Therefore, most foods Will not cause significant corrosion to aluminum foil.

The European Aluminum Foil Association (EAFA) points out that although aluminum ions may migrate into food due to the strong acidity and alkalinity of some foods, according to the current scientific status, aluminum intake within a reasonable range is not harmful to ordinary healthy consumers.

In addition, glucose, protein, pectin, fat and other substances in food and beverages can also act as inhibitors in acid-containing products to prevent food acidity from exceeding the corrosion stability range of aluminum foil. If dry products such as coffee, chocolate, and tea are stored directly in aluminum foil, corrosion problems will not occur.

When the pH of packaged food is high and may exceed the corrosion stability range of aluminum foil, a protective coating is usually applied to the surface of the aluminum foil to prevent the food from being contaminated by aluminum ions due to packaging corrosion.

In addition to its high corrosion resistance, aluminum foil is naturally non-toxic and odorless, and no bacteria or microorganisms can grow on the surface of aluminum foil. Aluminum foil itself is not volatile. It will not cause odor in packaged food, nor will it cause health risks due to direct contact with food.
