What Are Alloys of Aluminum Seal for Bottles

Induction sealing technology came out in the mid-1960s. It is a non-contact heat treatment process that melts aluminum foil (lining material) along the mouth of the bottle or jar. The sealing process occurs after the filling and capping process. The capped container is sealed by an induction device mounted on the conveyor belt. The alloys of aluminum seal for bottles include 8011, 1060, 1235, etc.

Compared with gaskets made of other materials, aluminum foil for bottle cap can ensure food safety. The surface of aluminum foil is very clean and no bacteria or microorganisms can grow on the surface of aluminum foil. Aluminum foil gaskets are mainly used to the beverage or red wine bottle sealing.

Its main function is to block direct contact between the bottle mouth and the inside of the bottle cap, thereby preventing the bottle cap from completely blocking the contact between the internal liquid and the outside air. This will preserve the quality of your food or alcoholic beverages for a long time and alleviate bottle breakage caused by handling or transportation.

Aluminum foil is a hot stamping material that is directly rolled into the thin aluminum sheets. It features soft texture, good ductility and silvery white luster. Aluminum foil sealing can ensure the sealing of the and extend the shelf life of the product.

This sealing gasket is composed of adhesive sealing layer, aluminum foil, weak adhesive layer, cardboard elastomer, etc. The aluminum foil gasket is embedded into the bottle cap to expose the aluminum foil.

Using the principle of electromagnetic induction, the aluminum foil on the bottle mouth instantly generates high heat, and then fuses to the bottle mouth to achieve the sealing function, which is leak-proof, moisture-proof, anti-counterfeiting and anti-theft.

According to the different characteristics of the sealing layer of aluminum foil sealing gaskets, they can be divided into: ordinary sealing aluminum foil gaskets, high-barrier aluminum foil gaskets and easy-tear aluminum foil gaskets. Ordinary sealed aluminum foil gaskets are aluminum foil gaskets used in general food, lubricants, daily chemicals, pharmaceuticals, etc.

High-barrier aluminum foil gaskets add a barrier layer between the sealing layer and the aluminum foil to protect against volatile solvents, strong acids, strong alkali or strong corrosive substances, such as pesticides, chemical detergents, gasoline additives, etc.

The sealing layer of the easy-tear aluminum foil gasket is coated with an easy-tear layer, so that the sealing effect is not affected and at the same time, the adhesion between the sealing layer and the bottle mouth is reduced. When the users open the bottle, they can easily tear off the sealing film on the bottle without leaving aluminum foil or plastic film on the bottle. Easy-tear sealing aluminum foil gaskets are mostly used in high-end food, health products, functional drinks, and cosmetics packaging.

Haomei Aluminum only provides the aluminum foil jumbo roll or aluminum foil sheet for the aluminum foil gaskets. All the main alloys like 8011, 1235, 8021 and 1060 alloy aluminum are available. Welcome to leave message below to inquire what you need.
