Hand mask manufacturing is a sealing problem more than a formulation problem. The product is a glove or a sleeve with a serum load, worn for 15 to 20 minutes, and the failure that generates complaints is a wrist seal that opens and leaves serum on the sofa. Everything else – the serum, the print, the fit – matters less than whether the glove holds.
1. Materials
Three constructions dominate. A PE or PP film glove welded at the wrist, the cheapest and most common. A non-woven laminated glove with a film inner layer, softer and better for print. A thicker embossed film glove, the premium format and the easiest to open without tearing. A flat die-cut pouch in a hand outline is a fourth option: less material, but it feels like a sachet rather than a glove.
2. The wrist seal
The seal has to hold 5 to 8 ml of serum against gravity and hand movement for 20 minutes. A straight weld across the wrist is the weakest point because the film gathers there. A tapered weld, 3 to 5 mm wide, cooled under pressure, is the practical answer. Test every batch with a 30-minute inverted hold plus a squeeze test at 0.2 bar; anything that leaks at the wrist fails regardless of how good the print looks.
3. Fit and the two-size problem
One size does not fit hands. A glove sized for a large hand hangs loose on a small one and serum pools at the fingertips; a small glove will not go onto a large hand. Two sizes with a clear mark on the sachet is the retail minimum. A universal glove with an elasticated wrist is a workable compromise for hospitality and gift sets, where exact fit matters less.
4. Serum load and viscosity
Five to eight millilitres is the working range. A watery serum runs to the fingertips and leaves the palm dry; a serum at 400 to 800 centipoise stays where it is applied. The serum also has to be non-slip enough that the wearer can open a door, which is a usability requirement rather than a formulation one: glycerin-heavy serums are comfortable and slippery, so most packs instruct the user to sit still for the wear time.
5. Warming formats
A self-warming hand mask uses an exothermic pack inside the glove, which raises the temperature by 5 to 8 degrees Celsius for 20 minutes. It is a strong winter and gift product, and it adds cost, a secondary pack, and a safety requirement – the warming material must not exceed a defined surface temperature. A conventional glove can be warmed in a bowl of warm water, which is cheaper and needs an instruction, not an ingredient.
6. Packaging and retail
A pair of gloves packs into a flat sachet with a fold line, or into a carton with a window. A carton holds the shape better on a shelf and costs three to four times the sachet. A five-pair box is the value format and the one that suits a weekly routine; a single pair is the trial format. Print has to account for the fact that the glove is inside out in the pack, or the design lands on the palm.
7. Commercial profile
Stock PE glove, 6 ml serum, MOQ 3,000 pairs, 25 to 35 days. A non-woven laminated glove adds two weeks. See the hand mask range and the foot mask guide for the matching lower-body format.
