    What are people's experience with induction sealing on glass bottles and achieving strong enough seals to sustain pressure from nitrogen flushing or altitude during transportation without leaking? Is it realistically achievable to get a bond between an induction liner and specifically, a glass container, that is strong enough to sustain these types of circumstances (assuming liner is intended for glass containers)?

    Hi there,

    Yes I have seen this done with no issues. Most of the vendors would probably be able to supply additional data sheets as well as study data. Please note the ones I have seen capable of this are 5mL and 10mL glass vials.

    Good Morning!

    We package fish oil softgels in glass wide mouth packer bottles ranging from 120cc to 400cc (38mm to 53mm closure size). We do get complaints from customers for failed seals. This usually occurs with our 53mm closure size. We currently use the Selig LPM (Universal Liner) to seal our bottles. However, I'll be conducting testing on the Selig LPF (Glass Specific Liner) in the next month. I'll be conducting a vacuum decay experiment on both the LPM and LPF liners. I'll keep you posted on the results.

    Are you doing any validation on induction seal parameters?

    We do random sampling on the line. However, shipping variables and environment weaken the seal strength.

    So typically you would also do shipping studies as well as validating any of those parameters in the shipping lane. This would be things like is refrigerated storage needed, does label adhesiveness hold up based on the region and market you are shipping it in.

    "However, shipping variables and environment weaken the seal strength." These are parameters that also need to be tested. 

    "We do random sampling on the line." What type of sampling plans do you use? and also do you do line check parameters, pre and post, to ensure no parameters "fell" out of requirements. 

    And not split hairs but I would think something other than glass bottles could be used for packaging. I would assume those are quite costly
