◆ Quality Series · Part 5
In short: a walk through the line, from purified water to a coded carton — and the parameters we lock at each step.
The process, step by step
- Purified water is prepared for compounding.
- The disinfectant solution is compounded to 75% (±10%).
- Pouches are formed from barrier film and nonwoven is cut to size.
- Metered alcohol fill — a defined volume per size (0.4 ml up to 12.5 ml).
- The pad is folded and pouched.
- The pouch is sealed.
- Each batch goes through a vacuum leak test.
- Cartoning and batch coding, then to stock.
The parameters we lock
| Stage | Control point |
|---|---|
| Compounding | Ethanol 75% (±10%) v/v — the first release-critical number |
| Filling | Metered volume per size (0.4–12.5 ml) |
| Sealing | Leak-free; vacuum 500 mmHg / 10 min |
| Batch record | Concentration, fill, equipment, operator, material reconciliation |
Changeover discipline
Production is mainly manual processing with automated packing. Between products or batches we run a documented line clearance to prevent mix-ups — a small step that protects traceability and lot integrity.
For buyers — what to ask for: ask to see a sample batch record — it shows whether concentration, fill and seal are actually recorded per batch.
