Closures and liners

By Dwight Davis, Founder

On this page11
81 heat induction seals. Which is what a gummy actually needs.

The closures

167 continuous thread polypropylene lids, 32 metal or aluminum CT caps, 21 dome lids, 19 CT CRC, 8 sealing discs, 2 phenolic, 2 dairy lids, 2 metal overshell lids, 1 tamper evident lid, 1 plug seal lid.

The liners are the real content

81 heat induction seal, 38 F217, 30 pressure sensitive, 28 No Liner, 23 PE foam, 21 unrecorded, 15 Plastis standard, 14 foam, 2 polycone.

Heat induction seal is the largest group

81 of 255, which is a genuinely good position for this category. A bonded foil is the moisture barrier a gummy needs.

And it is a one-time seal

So the closure underneath has to reseal afterwards, which for a 60 count jar opened daily is the second half of the decision.

F217 is the resealing answer

38 closures. Foamed polyethylene that keeps sealing through repeated opening, which is the right pairing with an induction seal.

49 of 255 have no liner or no record

28 recorded as No Liner and 21 blank. On a shelf for hygroscopic confections that is the first fifth to eliminate.

And a blank is not a claim

It is an absence of data. We do not guess at a liner, so blank means ask rather than assume there is none.

Child resistance is 19 of 255

Which for a product that looks like candy is the number to think about. What is required is not described here and the count is a count.

One tamper evident lid

Out of 255. For a supplement sold at retail, tamper evidence usually comes from the induction seal rather than from the closure, and the induction seals are there.

21 dome lids

Which add headroom without capacity. For a gummy that should not be compressed by its own lid, that is the reason to choose one.

Written from 21 CFR 101.36 and from the catalog as it stood on 19 October 2026. The surface area figures here are computed from published height and diameter and are the cylindrical side wall only, which is a lower bound: the regulation measures the total surface area available to bear labeling, and that is more. Nothing on these pages sets out what a Supplement Facts panel must contain, which ingredients may be used, or what claims are permitted. A dietary supplement's serving size is determined by reference to the amounts in 21 CFR 101.12(b) rather than by the maker.
