How It Compares
| Manual inner and outer bag assembly | The C18 replaces hand packing with consistent alignment and faster output, but requires a fixed power and air connection |
|---|---|
| Single inner bag machine | The C18 adds an outer envelope for branding and protection, but uses more material and space than a single bag machine |
| Flat bag machine with separate envelope | The C18 integrates envelope forming into the line, reducing steps, but is limited to the specified bag size ranges |
Use Guide

- 2Load the inner filter paper and outer envelope film rolls according to the material specifications
- 3Set inner and outer bag dimensions within the adjustable ranges for your product
- 4Adjust the volumetric cup to the desired fill volume between 3 and 15 ml
- 5Enable photoelectric positioning and test alignment with sample bags
- 6Run a batch of ten bags and check tag position, seal integrity and fill volume before full production
