The shelf, measured
One hundred and ninety-eight containers from 50 to 950 mL, with 235 closures. By material, 141 PET, 29 glass and 28 HDPE. The dominant necks are 89-400 at 72, 70-400 at 42, 58-400 at 29 and 53-400 at 18, so this is a wide-mouth shelf.
The forms
141 single wall jars, 18 straight-sided jars, 17 packers, 7 mason and paragon jars, 4 specialty jars and 4 spice bottles. Jars dominate, which suits something poured in and scooped out rather than dispensed.
Material, with the storage job in mind
Glass does not permeate at all, which for multi-season storage is a real advantage. PET is cheap, clear and light; HDPE is opaque and tough. All three work, and the closure matters more than any of them.
Color
75 clear, 36 white, 32 amber, 17 black, 16 blue and 11 green. Clear shows the seed, which sells; amber and black remove light as a variable for anything held for years.
The closures
210 continuous thread and 21 dome lids. By liner, 64 HIS, 42 F217, 31 pressure-sensitive, 26 with none, 21 of a standard plastisol, 19 PE foam and 15 foam. The HIS set is the route toward a sealed package.
What is not here
No foil pouches, no seamed cans and nothing vented. The first two are the formats most associated with hermetically sealed seed; the third is what a bulb needs. Both gaps are stated rather than worked around.
Where to settle the thread match
Every container page lists the closures verified against its own neck. What is left for you is the liner, the sealing process, and whether the filled weight puts you over or under the one-pound line.
