Closures and liners

By Dwight Davis, Founder

Updated

On this page8
The closure here is holding scent in, not holding liquid back, which changes what good looks like.

What the closure is for

A set melt cannot spill, so the lid is there to keep fragrance from escaping, keep dust out and survive handling. That is a vapor problem rather than a liquid one, and it is a far more forgiving brief.

The liner still matters

Fragrance oil migrates, and a liner in contact with a heavily loaded wax for months can discolor or soften. It is a small part and it is worth asking the supplier what it is made of.

The choice is wide

257 closures are verified against the necks on this shelf, and with 89-400 and 70-400 dominating there is real choice at the wide end. Every container page lists the closures matched to its own neck.

Capping a deformed neck

If a PET jar has moved in the pour, the lid is where you find out. A closure that goes on stiffly or crooked is reporting a container problem, not a closure problem, and swapping the lid will not fix it.

Clear lids and the display

A clear lid lets the wax show in a stacked display, which in a gift category earns its keep. It also shows frosting, sweating and any surface defect, so it raises the bar on the pour.

Standardize on one neck across the range

One finish means one closure and one liner bought in volume, and it means a single compliant label template rather than several. At the scale most makers in this category work at, that is the saving that actually shows up.

The forgiving part of this build

After the temperature rating and the taper, the closure is the easy decision on this shelf: a set melt cannot leak, the choice is wide, and the thread match is already verified for you on every container page.
