Key Benefits
- Forms and seals inner and outer bags simultaneously to double output compared to sequential machines
- Stepper motor control ensures consistent bag length and stable positioning across every bag
- Volumetric cup filling delivers repeatable 5 to 15 g per bag with minimal variation
- Ultrasonic sealing avoids heat damage to coffee aroma and maintains a clean, narrow seal edge
- Built-in connector for nitrogen flushing extends shelf life by reducing oxidation
- SUS304 stainless steel parts in direct contact with coffee meet food safety standards
- PLC control with human machine interface simplifies operation and reduces training time
Application Scenarios
- Coffee roasters packaging single-origin Arabica beans in retail-ready drip bags with a visible inner filter
- Contract packers handling multiple coffee brands with short batch runs and quick format changeover
- Export-focused producers meeting international packaging standards with nitrogen-flush capability
- Small to mid-sized roasteries replacing hand packing with a fully automatic line that fits a compact footprint
Who It Is For
- Coffee roasters transitioning from outsourced packing to in-house drip bag production
- Contract packers serving multiple coffee brands with varying bag sizes and fill weights
- Producers requiring nitrogen flushing to extend shelf life of roasted coffee
- Brands that need consistent bag length and seal quality for retail shelf presentation
Problems It Solves
- Hand packing of inner and outer bags is slow and inconsistent in fill weight and seal alignment
- Sequential machines that pack inner then outer bags reduce throughput by up to 50%
- Heat sealing damages delicate coffee aromatics and causes film degradation at the seam
- Inconsistent bag length leads to poor stacking and visual mismatch on retail shelves
- Lack of nitrogen flushing shortens shelf life and increases risk of stale or oxidized coffee
- Non-food-grade materials or parts in contact with coffee risk contamination and audit failure
Technical Features
- Ultrasonic sealing for clean, narrow, heat-free closure of inner and outer bags
- Stepper motor control for precise outer bag length positioning and stable sealing
- Volumetric cup filling system for consistent 5 to 15 g per bag across batches
- PLC control with human machine interface for easy operation and parameter setting
- All food contact parts made of SUS304 stainless steel for compliance with food safety standards
- Integrated connector for nitrogen flushing to extend coffee shelf life
- Optional flat cut, date printer, and easy tear device for added functionality

How It Compares
| Sequential inner and outer bag machine | The C19H forms and seals both bags at once, increasing output by up to 100% compared to machines that pack one layer at a time |
|---|---|
| Heat-sealed drip bag machine | Ultrasonic sealing avoids heat damage to coffee aroma and maintains a narrower seal edge, but requires an air supply |
| Manual bagging with hand sealing | The C19H replaces a hand-filling team and ensures consistent fill weight and seal quality, but requires a fixed 1200 x 900 mm footprint |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the selected film roll (180 mm inner, 200 mm outer) and thread through the forming guides
- 3Set the desired bag length using the stepper motor control and confirm positioning
- 4Enter fill weight between 5 and 15 g and calibrate the volumetric cup with your coffee
- 5Run 10 test bags and check fill weight, seal integrity, and bag length before batch start
- 6Use the reserved connector to link with a nitrogen machine if shelf life extension is required
