Uses of aluminum foils

Food packaging

Aluminum foil protects against moisture, light, oxygen and bacteria, which are key requirements in industries such as food and beverage and pharmaceuticals. In addition, aluminum foil has a reflectivity of 88% and is used as a thermal insulation material.

Sunlight quickly affects many foods, damaging their appearance and flavor. Aluminum foil is the most practical solution for these packaging needs, and as a result, this material has been regarded as the ideal core packaging material for dairy products, confectionery snacks and beverages. At present, flexible packaging is mainly used for food, with the fastest growing areas being coffee, snacks, fresh food, prepared food and pet food.

Market demand for aluminum foil packaging is expected to grow as aluminum is lighter, more durable, more flexible and has barrier properties compared to plastic and glass. Aluminum's ease of use, convenience, safety, light weight and durability make it ideal for use in a variety of industries and homes.

Pharmaceutical packaging

The pharmaceutical industry often uses blister packaging for pharmaceutical products. Blister packaging consists of a push-fit closure made of aluminum foil and molded plastic with cavities to hold individual tablets. Different types of medicines use different blister packaging materials. Aluminum-plastic packaging is mainly used for pharmaceutical packaging, but all-aluminum packaging is also used for other pharmaceutical packaging.

Cigarette packaging

Some companies have identified the unique barrier properties of aluminum foil to protect tobacco products from moisture, deterioration, aroma transmission, and bacteria by maintaining a microclimate inside the package. The growth of the tobacco industry is expected to drive the adoption of aluminum foil packaging in the future.
