Aluminum foil seal is widely used in medicine, food and beverage packaging. In the medicine packaging, the bottle aluminium seal is mainly used as packaging products inside various types of medical bottle caps. Its main function is to block direct contact between the bottle mouth and the inside of the bottle cap, thereby preventing contact between the inside of the bottle cap and the outside air. It can keep the quality of drinking medicine unchanged for a long time.

The aluminum foil seal is also used as a lid material, which is sealed on a hard sheet of pharmaceutical plastic polyvinyl chloride (PVC). Aluminum foil is made of electrolytic aluminum with a purity of 99% and is made by rolling. It is non-toxic and tasteless, has excellent conductivity and light-shielding properties, and has extremely high moisture resistance, gas barrier and taste retention.

Food packaging is an important market for aluminum foil applications. In the field of food and beverages, common food packaging aluminum foil application types include: aseptic packaging, food container, stand-up bags, wrapping paper, sealing cover films, high-temperature cooking bags, etc.

Aluminum foil or aluminum-plastic composite materials are often used for capsule sealing or cup body production. The barrier properties of aluminum foil can prevent the oxidation, acidification and volatilization of aromatic substances of coffee powder, extending the shelf life of coffee powder to 12-18 months. And if the coffee powder is stored in direct contact with the air, the high-quality flavor of the coffee can only be preserved for 3 days.

Under normal circumstances, 10um aluminum foil can already heat the sealing layer to a molten state under the action of induced eddy current, but the heating time will be slightly longer, and when the distance between the sealing head of the induction sealing machine and the aluminum foil gasket increases, the induction will failure, so the thickness of the aluminum foil of the sensing layer is generally above 15um. Nowadays, the thickness of the sensing layer of aluminum foil gasket is mostly as follows: 15um, 17um, 20um, 25um, 30um, etc.

Aluminum foil is the carrier of the adhesive layer, and its quality has a great impact on the heat sealing strength of the product. In particular, oil stains on the surface of the original aluminum foil can weaken the bonding force between the adhesive layer agent and the original aluminum foil. If there is oil on the surface of the original aluminum foil and the surface tension is lower than 3.1×10-2μm, it will be difficult to achieve the ideal heat sealing strength, so the quality of the original aluminum foil must be strictly controlled.
