Applications of 8006 aluminum foil

Packaging

Food and beverage containers, trays, and lids

8006 aluminum foil is widely used in the food packaging industry, mainly because of its characteristics such as good ductility, moisture resistance, light blocking and barrier properties. The following are the specific applications of 8006 aluminum foil in food packaging:

• Wrinkle-free lunch boxes: 8006 aluminum foil is particularly suitable for making wrinkle-free lunch boxes. After stamping, these lunch boxes have no wrinkles on the edges, and the overall appearance is flat and smooth, giving people a sense of high quality. At the same time, lunch boxes made of this aluminum foil can well maintain the temperature and freshness of food.
• Food packaging coils: When used as coils, 8006 aluminum foil can be used to wrap food, such as baked goods, candies, cooked food, etc., to ensure the freshness of food and prevent external contamination.
• Composite packaging materials: 8006 aluminum foil can also be compounded with other materials such as plastic film, paper, etc. to form composite packaging materials, which are used in various food packaging, such as beverage bottle cap linings, fast food packaging, etc.
• Special packaging requirements: For some foods that require high sealing and protection, such as coffee beans, tea leaves, etc., 8006 aluminum foil is an ideal choice because of its excellent barrier properties.

Pharmaceutical packaging

The main uses of aluminum foil for pharmaceutical packaging include:

• Blister packaging (PTP): This is the most common way to package pharmaceuticals. Aluminum foil is used in combination with plastic hard sheets (such as PVC or PVDC) to form a blister package. The drug is placed in the groove formed by the plastic and then sealed with aluminum foil.
• Strip packaging: This form of packaging encapsulates the drug in a continuous strip packaging, and each unit of drug can be separated by a tear line.
• Aluminum-plastic combination bottle cap: Aluminum foil can be used to make the inner sealing layer of the bottle cap to prevent drug leakage and protect the drug from contamination.
• Aluminum-plastic sealing gasket: Aluminum foil is used as a gasket at the seal of some bottles or containers to improve the sealing.
• Double aluminum packaging: This form of packaging uses two layers of aluminum foil to provide a higher level of protection and is generally used for drugs that are very sensitive to environmental conditions.

Industrial Uses

The industrial application of 8006 aluminum foil is indeed very extensive. As a high-performance aluminum alloy material, 8006 aluminum foil has unique advantages in various fields:
