Enercon, Selig Liners, Phoenix Closures and BellatRx recently presented a webinar on optimizing liners, caps and capping for induction sealing.
The webinar is available for viewing on-line.
During the question & answer session after the presentation attendees had the opportunity to ask the panel questions. Below are three of those questions and our panel’s responses:
What is the best method for liner retention?
With induction sealing the best results are with a friction fit, whether that’s with a retainer well or tabs and retention beads to keep the liner in the cap. By using a friction fit liner it allows the liner to contact the container and still allow the cap to spin and apply torque. If the liner is actually glued into the cap as soon as it touches the container its going to halt its application and prevent the cap from applying full torque. - Tim Ferrel, Phoenix Closures
What capping applications require servo torque?
Applications that require precise torque where you can’t allow any containers to pass downstream without the required torque. Specifically difficult caps such as raised lettering, yorker, tab caps and any applications where you want to benefit from the diagnostics capabilities of the servo control. - Alan Shuhaibar, Bellatrx
How can you determine which seal to use for a specific product, for example a high alcohol content or pH level?
Many products that may be similar in content often test differently, so the best method is to consult with your liner suppliers technical team. They can work with your company and test each application to ensure you have the liner that will work best for you. - John Brown Selig Liners
