What characteristics of foil affect the induction sealing?
The thickness of the foil layer and type of innereseal (single element or wax bonded two-piece) are the main foil characteristics that affect the induction sealing process. However, there are many other variables to consider.

How much should the foil hang over container lip?
It’s on a case by case basis and is typically dictated by the closure design and molding process. We can always evaluate samples to provide an opinion but the closure supplier should be the best resource.

What is the rule of thumb for sizing diameter of the liner in relationship to diameter of the bottle finish?

A barrier layer provides better barrier than the foil?
Good question. We use the term “barrier” in two ways. First, the foil provides barrier in terms of Moisture Vapor Transmission and Oxygen transmission. The foil provides a completely hermetic seal (when non venting materials are used). In some case, a “barrier” layer may be needed to protect the foil against the product.

What is the general thickness of the foils?
The most common are .001”, .005”, .00035” but others may be used. The .001” foil provides the widest processing window and is the easiest to run.

Can you speak a little more on the expiry dating of closures please?
Please visit our website at http://www.seligsealing.com Under the QUALITY section, see Recommended Storage and Handling. This will give you a detailed response. The closure supplier should be able to provide a position as well.

Can I specify a water vapor transmission rate for the foil?
This is a difficult question. If you would like to discuss this in detail please contact me (BJ Radek) at 630-922-3158 for additional discussion.

There have been a lot of trouble shooting tips focusing on the sealer, and the bottle & closure – are there any tips for evaluating the quality of the liners?
There certainly are. Please contact me (BJ Radek) at 630-922-3158 to discuss.

Very interested in an induction liner that vents slowly allowing off-gassing over time. Recommendations?
For dry products FoilSeal 5-4 or FoilSeal 5-10. You may also discuss mechanical venting with you closure supplier or contact Performance Systematix at 616-949-9090
