Extended shelf life, increased consumer confidence and tamper evidence are among the benefits that a major healthcare manufacturer has gained since moving to induction cap sealing.

​

Lifeplan, a leading UK supplier of vitamins and mineral supplements, began induction sealing its products with Enercon Industries’ equipment after deciding to stop using tamper evident push-on lids.

​

Rod Bray, Operations Manager at Lifeplan, said: “After changing to screw cap lids with induction seals, we have found we have much better product stability as the product is hermetically sealed in our containers.

​

“This is particularly true on our more sensitive products and in some cases this has allowed us to increase their shelf life.”

​

As well as an extended shelf life, the company has also seen an increase in customer satisfaction.

​

“Customer feedback has shown preference for an induction seal with a screw cap lid, as consumers find them much easier to open on first use,” explained Mr Bray.

​

“We use seals that have ‘sealed for your protection’ printed on them, which increases consumer confidence in the product,” he added.

​

By adding an induction seal to a container, companies gain the added benefit of tamper evidence, which is often a requirement for those in the healthcare and pharmaceutical industries. A tamper-evident design reassures the consumer that a product has not been modified since leaving the manufacturer.

​

Speaking about this, Mr Bray said: “Induction seals offer very good tamper protection, as it is impossible to tamper with the product without making an obvious break in the seal.”

​

Lifeplan produces over 280 products which are exported to more than 40 countries worldwide. In a single production shift, the company will induction seal around 10,000 containers using Enercon’s Super Seal 75 induction cap sealing machines.
