Tamper Evidence is one of the benefits of induction sealing your product. An intact seal, will assure the consumer that the product has not been tampered with and can be sure of its authenticity.
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.
Induction sealing can provide tamper evidence to its users as foils must be removed or destroyed in order to access the product. This is particularly important for the safety and satisfaction of consumers. Thanks to an intact seal, the consumer knows the product has not been tampered with and can be sure of its authenticity.
