Induction sealing onto glass jars was previously an impossible task. In the past, achieving tamper evidence for glassware was accomplished through the use of Heat Shrink Tamper Bands which proved disadvantageous. They were difficult to apply in production; they were difficult to remove for the end user. They were often dust traps and even appeared to attract dust to the product.
Now, however, with induction sealing, we no longer need to worry about such dilemmas. Sealing onto glass is executed through a Foil-Under-Cap Approach where the cap is loaded with an induction foil when it is placed onto the container. This allows for tamper evidence and a secure seal for the product.
What are the advantages of Capless Sealing?
- It enables induction sealing of containers with metal caps without the risk of them heating too much and becoming volatile and unsafe for product contact. This is achieved because the capless sealing process takes place prior to the metal cap being placed onto the container.
- It allows for much higher contact pressure of the sealing foil during the induction process, making sure that the foil remains bonded with time.
