Introducing Induction Cap Sealing About Induction Sealing

Induction cap sealing or heat sealing, as it is widely known, is a very simple and straightforward process.

The container is filled and the cap (fitted with a foil liner) is applied. The capped container then passes under the induction cap sealer where a controlled electromagnetic field transfers energy to the foil in the cap, creating heat. This melts the sealing material on the foil liner. Once this sealant cools, the liner adheres to the neck of the container – this is known as a hermetic (air tight) seal.

The Benefits of Induction Heat Sealing

Counterfeit Protection

Induction sealing provides counterfeit protection to its users as an intact seal can show customers that the product has not been modified. This is particularly important in the pharmaceutical industry, where counterfeit medicines are an increasing problem. Statistics show that as many as 1 million people die every year from ingesting counterfeit medicines.

Counterfeit protection is also popular in the cosmetic industry, particularly for products of a high value, and for easily imitable products such as water, where original product manufacturers want to avoid the risk of losing brand equity.

In response to counterfeiters becoming increasingly more sophisticated, induction seals have also become more advanced with options such as etched or engraved foil, colour-shifting inks, micro-printing, printed or electronic (RFID) codes, custom colours and inks with DNA added.

Eco-friendly

Extended Shelf Life

Increased Productivity

Induction sealing technology allows for high performance machines to perfectly seal containers in record time. This is due to the machines being able to work at high speed, without the need to touch or handle the product. Induction sealers can be powered on and ready to use almost instantly; they can also provide a hermetic, reliable and strong seal in under a second. This prevents time being wasted by long warming up and cooling down periods.

Induction sealers are easier to move from one production line to another as they can simply be wheeled into place over an existing section of conveyor. No time is wasted and production can go on without further interruption.

Leak Prevention

Induction seals can be used to prevent products from leaking. The technology used in induction sealing guarantees airtight sealing that can endure considerable pressure.

This ensures your product will not leak during storage, the transportation process or before your consumer is ready to use your product.

Many larger retailers and shipping companies – including Amazon – require a form of leak protection such as an induction seal.

Many of Enercon’s customers began induction sealing to prevent leaks that were occurring from the use of other closure methods, such as tear band closures and glue sealing.

Unit Cost Reduction

Saving money is one of the first reasons manufacturers move to induction cap sealing. How they save money can be achieved in many ways:

The considerable energy savings and increased output from running the machine
The reduction in costs from recalled products that have leaked
Extended shelf life
Reduction in maintenance
Reduced downtime
Reduction in the amount of material used in the closure and container

Virtually no Maintenance

The latest range of air-cooled sealers require virtually no maintenance or consumables to continue to work effectively and efficiently – in fact some of our customers describe their 20-year-old machines as ‘like new’. The minimal maintenance costs and the reduction in production downtime are what make Enercon’s range of induction sealers the number one choice worldwide.

In comparison to other sealing methods, such as conduction, an induction sealer can provide reliable and secure seals without having to touch or handle the containers – no contact between the sealers and the containers is necessary. This is particularly useful as it means the equipment does not have to be cleaned regularly, as with a conduction sealer.
