What is induction cap sealing?

It is a process where the liner within the cap of the bottle is sealed on the mouth of bottle using induction heating. The filled and capped bottle is passed under the cap sealing machine head and the sealing is done through a no contact method. The liner within the cap has multiple layers.

What are induction seals made of?

Although there are various liners to choose from, a typical induction liner is multi-layered. The top layer is a paper pulp that is generally spot-glued to the cap. The next layer is wax that is used to bond a layer of aluminum foil to the pulp. The bottom layer is a polymer film laminated to the foil.

How do you test an induction seal?

A simpler method is simply to remove the closure from the sealed container, turn it upside down, or on its side and squeeze. This is a good test to get a feel for the strength of the seal. However, you may have a microscopic leak that will not be detected with this method.

What is the purpose of induction sealing?

Induction Sealing is the method that involves the bonding of thermoplastic materials by inducing heat in them. The use of the above methodology takes places in the process of cap sealing. In this process, the seal is formed at the opening of any container or bottle with the help of heat.

Does induction sealing preserve food?

Benefits of Induction Sealing: Protecting Your Product & Customers. Induction sealing is a lightweight, effective method to preserve freshness, prevent leakage, and show clear evidence of tampering.

How does foil sealing work?

The heat melts the wax, which is absorbed into the pulpboard backing and it releases the foil from the cap. The polymer film also heats and flows onto the surface of the container. Once temperature cools down, the polymer creates a bond with the container resulting in a hermetically sealed product.

Can you induction seal glass bottles?

An induction seal prevents product leakage, is tamper-evident, maintains product quality, and fosters consumer confidence. Glass containers can be induction sealed, but the majority of induction – sealed containers are plastic.

What is a seal in engineering?

A mechanical seal is a device that helps join systems or mechanisms together by preventing leakage (e.g. in a pumping system), containing pressure, or excluding contamination. The effectiveness of a seal is dependent on adhesion in the case of sealants and compression in the case of gaskets.

What are Induction wads?

Induction sealing wads: materials are one of the most important parts in packing industry for sealing the bottles and containers of the products for many reasons. And induction sealing is a simple and reliable method of bottle sealing. It welds an aluminum foil seal across the bottle neck.
