How It Compares
| Manual inner and outer bag assembly | The C18 replaces a hand-filling team and ensures consistent tag alignment and fill volume, but requires a fixed floor space of 1250 x 700 mm and trained operator |
|---|---|
| Single inner bag machine | The C18 forms both inner and outer bags together, reducing handling and improving hygiene, but uses more film and requires more setup time |
| Semi-automatic bagging line | The C18 runs at 40 to 60 bags per minute with photoelectric tag positioning, but needs a stable 220V 50Hz power supply and compressed air for sealing |
Use Guide
- 1Connect a clean dry power supply at 220V 50Hz and ensure 3.7 kW capacity
- 2Load the selected film roll (paper/plastic, plastic/aluminum/plastic, etc.) matching your bag size
- 3Set inner and outer bag dimensions using the adjustable guides for 50-70 mm and 70-120 mm lengths
- 4Configure tag size and position using the photoelectric sensor settings
- 5Fill the volumetric cup with your tea and run a test batch of 10 bags to verify fill and seal
- 6Clean the filling cup and sealing area between product changes to prevent cross-contamination
