What the container actually does to moisture
On this page11
Headspace first
Air above the fill is a reservoir. A large headspace over a small fill exchanges more with the product than a full jar does, and this shelf starts at 30 mL.
So fill the container you choose
Which sounds obvious and is the commonest error on this shelf, because the sizes jump: 30, then 59, then 118, then 237. There is no 80 and no 160.
Liner second
The seal between the closure and the land is where exchange happens. 73 heat induction seal and 41 F217 closures here are the two that resist it.
Heat induction seal is the strongest
It is a bonded foil over the mouth, so it is a real barrier until it is broken. 73 of 260 closures here carry one, which is the largest single liner group.
F217 is the resealable workhorse
A foamed polyethylene liner that keeps sealing after the jar is opened. 41 of 260, and the right answer for a container the customer opens repeatedly.
Pressure sensitive is the weakest of the three
31 closures. It adheres on first closing and is a tamper indication more than a long-term barrier.
Wall material third
66 PP and 31 glass. Glass is the better barrier and PP survives being dropped, and for a moisture condition over months glass is the safer choice.
Light is a separate axis and the shelf is weak on it
19 clear containers against 8 amber and 4 frosted, on a group the archetype flags light sensitive. 12 of 97 protect the contents without hiding them entirely.
Black and white block light too
29 white and 11 black, which brings the opaque count to 52 of 97. For a product customers want to see, that is the trade.
Order of operations
Dry the product right, then fill the container near full, then specify the liner by name. A good liner on a half-empty jar is still a half-empty jar.
