The split

Four to one, the wrong way

By Dwight Davis, Founder

On this page14
And glass is the better answer for two of the four leaves.

The split

117 PET, 78 polypropylene and 56 glass out of 251 containers. 195 plastic against 56 glass.

Which is a little over four to one

And is the ordinary shape of this catalog, because plastic is lighter, cheaper and unbreakable.

For most groups that is the right weighting

A jar of beads, a jar of buttons or a jar of dried fruit does not care what the wall is made of.

For a light steel part it is the wrong one

Because a plastic wall takes a static charge and a light steel part clings to it.

Which is the finding for this group

Two of the four leaves are light steel: a lock pin and a tumbler spring. Both cling.

And the other two are scratched rather than held

A key blank has a profile and a finish, and a padlock part has a working surface. Plastic walls score both.

So glass serves all four leaves better

No static, no scratching and no hazing, and there are 56 of them.

Against glass's own weakness

It breaks, which in a van or a tool bag is a real consideration and is why the catalog is weighted the other way.

The compounding property measures that trade

Our material ratings put glass at 5 of 5 for chemical resistance and 1 of 5 for impact, the only low rating in either set.

So the choice is static against breakage

Which is a genuine trade rather than a right answer, and this property names it rather than resolving it.

And the shelf lets you make it either way

56 glass containers is a fifth of the shelf, which is enough to build a kit from.

Polypropylene is the worse plastic of the two for static

78 containers. A polyolefin holds a charge more readily than PET, which is why the 117 PET sit in the middle of this question.

Which is the one axis of this shared shelf that this group needs

Sixteen groups use these 251 containers and for this group the material is the decision.

The Davis Pack Supply catalog, measured 19 October 2026. The 251 containers on this shelf are 117 PET, 78 polypropylene and 56 glass, so 195 plastic against 56 glass, a little over four to one. For a small metal part the difference is practical: glass does not scratch, does not haze and does not take a static charge, and both plastics do all three.
The Davis Pack Supply catalog, measured 19 October 2026. 539 rows: 251 containers and 288 closures. This is the store-small-dry shelf, shared identically by nine groups, and the sewing notions property enumerates the inventory. 5 to 500 mL with a median of 177, with 60 containers under 60 mL and 22 under 30. 210 jars, 27 bottles, 12 tubs and pails, 2 tubes. Buyability, a snapshot: 159 of 251 available, 91 not, 1 unrecorded; 93 quote only; 65 full case only, with case packs from 12 to 6,370 and a median of 288.
Written from 18 U.S.C. 1704 and from the catalog as it stood on 19 October 2026. That section is a theft and forgery statute about keys to Postal Service locks and says nothing about containers, labeling or packaging; it is quoted because it is the federal provision that names a key. Nothing here addresses the lawfulness of making, holding or selling any key or key blank, locksmith licensing, restricted keyways, key duplication, or whether any mark has legal effect, and nothing here would assist anybody in defeating a lock. This shelf is shared identically by nine groups and the sewing notions property enumerates the inventory.
