Key Benefits
- Produces inner and outer bags simultaneously, doubling output compared to sequential packing
- Ultrasonic sealing creates a strong, clean seal without heat or adhesive, preserving coffee aroma
- Volumetric cup filling ensures consistent fill weight across 5 to 15 g per bag
- Stepper motor controls outer bag sealing for accurate positioning and stable length
- PLC control with human-machine interface allows simple setup and monitoring
- Reserved connector enables nitrogen flushing to extend shelf life, reducing oxidation
Application Scenarios
- Coffee roasters packaging single-serve drip bags for retail or direct-to-consumer sale
- Contract packers handling short runs of multiple coffee blends with quick changeover
- Brands launching new coffee lines requiring inner and outer bag packaging in one line
- Facilities upgrading from manual packing to automated inner-outer bagging with nitrogen flush
Who It Is For
- Coffee roasters moving from outsourced packaging to in-house drip bag production
- Contract packers serving multiple coffee brands with different bag sizes and formats
- Brands that need nitrogen flushing to extend shelf life of roasted coffee

How It Compares
| Single-layer coffee bag machine | The C19D produces both inner and outer bags, offering better protection and branding space, but requires more film and setup time |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids film scorching and maintains film integrity, but requires an air supply and higher component cost |
| Manual bagging line | The C19D replaces a team of packers and ensures consistent fill and seal, but needs a fixed floor space of 1200 x 900 mm and trained operator |
Use Guide
- 1Connect a clean dry power supply at single phase 220V 50Hz and 3.7 kW
- 2Load the inner and outer film rolls matching your chosen 180 and 200 mm widths
- 3Set inner bag size to 50-75 mm and outer bag size to 85-120 mm as needed
- 4Enter target fill weight between 5 and 15 g and calibrate the volumetric cup with your coffee
- 5Run ten sample bags and check fill weight, seal quality, and bag length before batch start
- 6Use the reserved connector to link with a nitrogen making machine if shelf life extension is required
