A 500 ml PET serum bottle is a common, high-intent spec for brands launching or scaling a serum product. This page covers the material fit, the right closure and neck finish, and how to source it direct from a factory with low MOQ and custom decoration.
Bottles from our catalogue — 500 ml PET bottles.
Why specify a 500 ml PET serum bottle
At 500 ml, this format balances shelf presence and fill cost for a serum product. PET is clear and rigid, which suits a serum where clarity and a premium feel matter. We tool this capacity across our PET range so the shape, neck and closure are proven before you order.
PET suitability for serum
PET fits: leave-on, low-active formulas: serums, toners, facial mists, premium water-style bottles. Avoid it for: strong acids, high alkalis and essential-oil-heavy blends (stress-crack risk). For export, note that clear PET is one of the most recycled plastics. If PET is not the right call, the usual alternatives are HDPE (if opaque / chemical-resistant needed) and PETG (if clarity + tougher formula).
Closure and neck finish
A serum bottle at this size normally takes a dropper or airless pump. The neck finish is 28/410, which means any standard 28/410 closure fits — so you can source the pump or cap separately and still seat it on our bottle. We confirm the neck at quotation so nothing is stranded.
Customization, MOQ and lead time
Stock PET bottles in this capacity start around 5,000 pcs; custom colour or plating begins near 10,000 pcs. Add silk-screen or hot-stamp decoration from a signed proof. Stock + simple print typically runs a few weeks; we bridge smaller first runs where volume is still proving out.

|---|---|---|
| PET | leave-on, low-active formulas | See avoids |
| HDPE | HDPE (if opaque / chemical-resistant needed) | Different look/property |
| PETG | PETG (if clarity + tougher formula) | Different look/property |

The 500 ml PET body is one of the shapes we run most often for this application. The table shows representative stock molds — most projects start from one of these and tune neck, colour and decoration.
Starting from a stock mold means a real, fill-tested bottle in days rather than waiting on a custom tool, which is usually the fastest way to de-risk a new SKU.
How we make and inspect the body
The bottle is blow-molded on our lines, then weighed and visually checked for flash, neck roundness and wall uniformity. Decoration (silk-screen, hot-stamp or label) is applied after the body passes inspection, and a final leak-spot check goes on filled samples.
Because the tool is in-house, sampling lead time is short — typically 3–10 days from drawing to first article — and repeats stay consistent because the same mold and resin are used every run.
Sizing the closure to this body
A 500 ml body needs a closure matched to its neck and its fill weight. Lighter, low-viscosity products suit a narrow dropper or mist; heavier or thicker fills want a wider neck and a pump or trigger that primes cleanly.
Tell us the closure you plan to use at sampling so we can confirm the neck and the sealing band before bulk — a mismatch only shows up once the line is running, and that is the expensive place to find it.
Next step
If this body looks close to what you need, send us your fill volume and planned closure and we will confirm the neck and the sealing band on a sample first.
Stock molds in this size family usually sample within 3–10 days, so you can prove the bottle before committing to volume.
