Bath Salt Tins
A bath salt tin has to do two things at once: keep the salt dry between uses and look good on a shelf. We supply custom aluminum bath salt tins with screw, click, slip, and window lids, matched to your salt blend and fill weight.
Bath Salt Tin Sizes & Fill Capacities
| Capacity | Diameter × height | Approx. Epsom salt fill* | Lid types available |
|---|---|---|---|
| 60 ml | Confirmed against your sample | ~48 g | Screw, click |
| 130 ml | Confirmed against your sample | ~104 g | Screw, slip, window |
| 250–300 ml | Confirmed against your sample | ~200–240 g | Screw, window |
| 500 ml–6,000 ml | Confirmed against your sample | ~400 g and up | Screw, click |
Our aluminum bath salt tin catalog spans 5 ml to 6,000 ml, including low-profile flat tins at 60 ml and 130 ml built for compact fills. Fine Epsom salt and coarse sea salt pack at different densities, so we verify the exact fill line against a sample of your blend before confirming a size.
*Approximate weights assume roughly 800 g/L bulk density for fine Epsom salt. Coarser salts and blends with botanicals or oils pack differently, so we confirm your actual fill weight against a sample tin.
Lid Options — Built for a Hygroscopic Product
Salt absorbs moisture from the air faster than wax, powder, or cream, so the closure carries more of the packaging job on a bath salt tin than it does on most other product tins.
-
Screw lids
A threaded screw lid holds its seal through repeated opening, which matters for a retail pack customers dip into over weeks. Compare screw-lid thread specs and seal types before you choose a fit for your bath salt tin.
-
Window / clear-top lids
A window or clear-top lid shows the salt’s color, crystal size, or dried botanicals before purchase — the format most bath-salt tins on a retail shelf actually use. We review the window material and its attachment alongside the body so visibility doesn’t come at the cost of moisture protection.
-
Slip & click lids
Slip and click lids suit gift sets, favors, and travel sizes opened once or only occasionally. For parcel transit or longer storage, we add a liner to give the same moisture protection a screw lid provides.
Liners & Seal Integrity
We fit an induction liner or foam seal pad under the lid to add a second moisture barrier during shipping and shelf life, independent of how tightly the lid itself closes.
We recommend this for any bath salt tin that travels by parcel or sits in a humid bathroom for months rather than weeks.
Finishes & Branding
Bath salt tins take labels, laser marking, screen printing, embossing or debossing, and matte, glossy, frosted, or metallic finishes for gift-set branding.
Bodies are aluminum — a cosmetic and wellness packaging material, not a food-contact grade. No food-grade certification applies to a bath salt tin.
FAQ
Do bath salts need to be in a sealed container?
Yes — bath salts are hygroscopic and absorb moisture from the air, which causes clumping and shortens shelf life, so a tight screw or click seal is recommended over a loose-fit lid.

Sourcing Process — Samples, Sizing & Quotes
MOQ and lead time are not fixed figures for a bath salt tin. We confirm both after reviewing your tin body, lid, decoration method, artwork, and order quantity.
Once the container drawing and artwork are approved, we schedule your sample run before committing to production tooling. Pricing and timing therefore reflect the actual configuration you are ordering, not a generic catalog number.
