Among the current packaging materials, aluminum foil has very good barrier properties. With this advantage, aluminum foil is widely used in various packaging materials. The demand for aluminum foil in the food packaging industry continues to grow, mainly because aluminum foil has good barrier properties, which can effectively prevent food from moisture, oxidation and bacterial invasion, thereby extending the shelf life of food.
Whether you go to the barbecue or use the oven at home, you will often use aluminum foil wrap to wrap food for grilling, steaming, and baking. Aluminum foil is only a thin layer, usually no more than 0.2mm thick, but it has strong thermal conductivity and high temperature resistance.
In the building materials industry, aluminum foil is mainly used in the production of roof insulation and thermal insulation materials. Aluminum foil can reflect the heat energy of sunlight, reduce the temperature rise inside the building, and improve energy efficiency. In addition, aluminum foil is also waterproof, moisture-proof and fire-resistant, making it an important part of the building materials industry.
Electronic aluminum foil is a kind of aluminum foil made by a series of rolling, cleaning and cutting processes on high-purity aluminum ingots, and is often used in electronic components. Electronic foil is mostly high-purity aluminum foil, such as 1070 aluminum foil, 1100 aluminum foil, etc., which has good electrical and thermal conductivity and is a common material for electrolytic capacitors. At present, most of the heat exchangers of air conditioners are designed with copper tubes and aluminum fins, which mainly include copper tubes, aluminum fins, and end steel plates. Aluminum used in air conditioners is currently mainly in the form of aluminum foil, which is used to make air conditioner condenser and evaporator fins.
Medical aluminum foil is used in pharmaceutical packaging in the form of aluminum-plastic blister packaging (PTP), tropical aluminum blister packaging, and alu alu packaging. Among them, the PTP blister foil is the main application, with the advantages of moisture-proof, hygiene, safety, and convenience, thus becoming a new type of pharmaceutical packaging method widely used internationally.
Tropical aluminum blister packaging is not a substitute for cold-formed aluminum, but a different packaging solution for different medicines in terms of moisture-proof requirements and display effects. The main difference between tropical aluminum and cold-formed aluminum in function is its moisture-proof effect.
