Formed, filled and sealed in one sequence
Polymer is extruded, shaped into the container, filled, then closed before the unit leaves the machine.
Blow-Fill-Seal contract manufacturing
BFS contract manufacturing for single-dose skincare.
Start with a formula, an existing sample or early specifications. We coordinate polymer and format questions, container design, sample development, manufacturing controls and pack-out around the intended dose and target market. If BFS is not the right fit, we can compare glass or preformed-container filling before development advances.
CONVENTIONAL GLASS AMPOULE
A preformed glass pack with a break-open neck.
- PRIMARY MATERIAL
- Preformed glass
- OPENING FORMAT
- Scored or one-point-cut neck
- KEY CONSIDERATION
- Breakage and glass fragments need handling controls
BFS SINGLE-DOSE AMPOULE
A polymer pack formed, filled and sealed in one machine cycle.
- PRIMARY MATERIAL
- Polymer selected for the formula
- OPENING FORMAT
- Twist-off head formed with the container
- KEY CHARACTERISTIC
- Dose, container geometry and opening can be set together in the mold
BFS format advantages
Six format facts that matter for pack selection.
These points help compare a BFS polymer unit with a conventional ampoule: how the pack is made, how it opens, and how dose and pack-out are chosen.
Fewer empty-container handling steps
No separate empty pack is washed, stored or transferred before filling; the container is made in line.
Lightweight and shatter-resistant
The polymer unit is lighter than glass and does not shatter like a glass ampoule in handling, transport or opening.
Opening and dispensing features integrated
The opening is molded with the container, typically a twist-off head rather than a scored glass neck.
Designed around the intended dose
Fill volume and container geometry are set together, then reviewed against the formula and the intended use amount.
Single units or connected strips
The mold can release separate units or a connected strip, depending on handling and secondary-pack needs.
Fit still depends on the formula and how the unit will be used, including barrier need, dose and opening method.
THE MANUFACTURING CYCLE
How blow-fill-seal works.
From polymer to sealed dose.
Explore the six stages of blow–fill–seal manufacturing.
Material preparation
Polymer Feeding
Selected polymer resin is delivered into the extrusion system under controlled processing conditions.

BFS development and manufacturing
Move from project brief to confirmed BFS production.
We turn early inputs into a defined container format, physical samples and an agreed manufacturing version, so the product and pack are reviewed before volume is planned.
Step 1.
Start with the brief you have
Bring a formula, product sample or early specification. We identify the intended dose, material questions and target market.
Requirements become a container format
Step 2.
Develop the BFS format
Set the unit presentation, opening method and secondary-pack direction around the intended use.
The selected format becomes physical units
Step 3.
Make and review real units
Create physical units to review the format and project requirements before volume manufacture is planned.
Sample, controls and documents aligned
Step 4.
Confirm the manufacturing version
Proceed against the confirmed sample, project controls and agreed document set.
The facility illustration is generic. Project format, controls, documentation and manufacturing arrangements are confirmed case by case.
Route Insights
How this route is compared.
What is sterile single-dose skincare?
The flagship answer: what the format is, how exposure is controlled, and how to read the preservative question.

Before you send it
What should a BFS contract manufacturing brief include?
Share the formula or existing sample, intended dose, opening method, target market and expected order quantity. These details help us review container compatibility, sample development and production requirements. Minimum order quantity, timing and documentation scope are confirmed for the project after review.
Is BFS right for every single-dose product?
No. The formula, barrier needs, intended dose, opening method and target market must fit the BFS route. Glass and preformed-container filling remain separate options. If you are choosing between a ready-to-use liquid and a dry product prepared at use, read the freeze-drying and BFS application comparison.
What can a BFS contract manufacturing project include?
The agreed scope can include formula development or transfer, container and opening development, filled samples, forming-filling-sealing, project checks and secondary packaging. SteriDose coordinates that scope with the selected partner factory. Specify whether the quote covers supplied bulk filling, filled units only or finished retail packs; these are different offers.
What determines the MOQ for a BFS skincare project?
MOQ depends on the formula batch, resin or component requirements, mould status, filling run and secondary-pack quantities. State the order in individual units and, where relevant, retail sets. Tooling, samples, testing and pack assembly should be identified separately in the quotation; there is no single published MOQ for every BFS format.
Can you compare BFS with glass or a preformed container?
Yes. We can review the same product brief against material compatibility, barrier needs, container design, opening method and manufacturing route before development advances.
Does BFS remove downstream inspection?
No. Inspection follows the continuous forming, filling and sealing sequence. The inspection scope is confirmed for the project.
