How Does Induction Sealing Work?

Induction Sealing

Have you ever wondered how those tiny metal disks on the lids of your jars keep them from leaking? They’re called induction seals, and they’re made with a thin layer of foil that’s heat-sealed to the lip of the jar with an induction sealer machine. Keep reading to learn how it works.

The Process of Induction Sealing

Induction sealing is a process that uses heat to create a hermetic seal on the surface of a container. It’s formed by the application of heat to the neck of a container, which melts the material, usually a metal foil liner, and forms a seal. The seal is hermetic, meaning it’s airtight and watertight. Induction sealing is used to package food, beverages, supplements, and pharmaceuticals.

The process begins with the selection of the proper sealant. The sealant must be compatible with the material of the container and the product to be packaged. The sealant is also chosen based on the type of closure to be used. The closure may be a screw cap, a snap-on cap, a lug cap, a crown cap, or a hinged lid.

The next step is to apply the foil sealant. The sealant is applied to the surface of the container and it’s essential to apply it evenly so that the seal is uniform. The final step is to apply heat to the container. This is done with an induction sealer. The sealer generates heat that’s applied to the neck of the container. This heat melts the sealant and forms an inner seal.

The Benefits of Induction Sealing

Induction sealing provides numerous benefits for both the manufacturer and the consumer. For the manufacturer, it provides a means of tamper evidence, as the foil liner cannot be removed without causing damage to the container. It also helps protect the contents of the container from contamination and degradation.

For the consumer, it provides a means of assurance that the contents of the container have not been tampered with and are safe to use. It also helps to protect the contents from contamination and degradation.

Induction sealing is a reliable and efficient means of packaging and protecting the contents of a container. It provides a means of tamper evidence and protection from contamination and degradation.

Why Product Containers Need Tamper-Evident Seals


When it comes to product containers, tamper-evident seals are essential for protecting the product and preventing any potential tampering from taking place. If a product is not properly sealed, there is a greater risk of it being compromised in some way, which could lead to serious health and safety hazards.

Tamper-evident seals are designed to indicate if a product package has been opened or tampered with after it has left the manufacturer. There are a variety of different types of tamper-evident seals, but all of them share one common goal; to provide an extra layer of security and protection for the product.

Some of the most common tamper-evident seals include induction seals, taped seals, and shrink bands. All of these are designed to be tamper-evident, meaning that they will indicate if they have been disturbed in any way.

Tamper-evident seals are an essential part of any product packaging strategy. They provide an extra layer of security and protection for the product and can help reduce product recall costs and protect the brand and reputation of the company.

Investing in an Induction Sealer

Overall, induction sealing is an important process that helps preserve the quality of a product. It helps keep out contaminants and extends the shelf life of a product. So, consider investing in an induction sealer to protect your products, customers, and reputation.
