Gummy vitamin
A soft gelatin or pectin confection, which means it is hygroscopic and will stick to itself and to the jar if it takes up moisture.
Energy chew
The same physical problem with a different formulation. Softer, often oilier, and more prone to deforming under its own weight in a tall jar.
Chewable tablet
A compressed solid, which behaves completely differently. It chips rather than sticks, and it is far less sensitive to the headspace humidity.
So the liner matters most for the first two
A gummy in a jar with no moisture barrier fuses into a block, and the customer concludes the product is old. 81 of the 255 closures here carry a heat induction seal and 38 carry F217.
And 28 are recorded as No Liner
With 21 more unrecorded. For a gummy that is the portion of the closure shelf to rule out before anything else.
Heat induction seal is the one to ask for
A bonded foil across the mouth, intact until broken. It is the largest liner group here and it is the right answer for a hygroscopic confection sold sealed.
F217 is the resealable follow-up
Foamed polyethylene that keeps sealing after opening, which matters because a 60 count jar is opened sixty times.
A tablet is more forgiving
And still benefits from the seal, because a compressed tablet can soften and lose its surface in a humid jar.
The jar shape is right for all three
111 of 163 containers are PET single wall jars with wide necks, 69 of them at 89-400. A wide mouth is what lets a piece come out without being chased.
And the area band is the same for all three
Because it is a property of the container, not the contents. Three leaves, one label question.
