Key Benefits
- Produces inner and outer bags simultaneously, reducing line time compared to sequential packing
- Ultrasonic sealing ensures a clean, narrow seal without heat damage to the film or coffee aroma
- Volumetric cup filling delivers consistent weight across 5 to 15 g per bag with minimal giveaway
- Stepper motor controls outer bag sealing position with high accuracy and stability
- SUS304 stainless steel parts in direct contact with coffee meet food safety standards
- Built-in connector for nitrogen flushing extends shelf life by reducing oxidation
Application Scenarios
- Coffee roasters packaging small batches of single-origin drip coffee for retail or direct-to-consumer sale
- Contract packers producing branded coffee bags for multiple clients with quick format changeover
- Roasters upgrading from manual packing to automated inner and outer bag formation
- Brands requiring a premium look with a visible inner filter bag and sealed outer wrapper
Who It Is For
- Coffee roasters moving from hand packing to in-house automated inner and outer bagging
- Contract packers serving multiple coffee brands with different bag sizes and formats
- Brands that need a sealed outer layer to protect coffee from moisture and light
- Buyers replacing a two-machine setup with a single integrated inner and outer bagging line
Problems It Solves
- Manual inner and outer bagging is slow and inconsistent in fill weight and seal quality
- Heat sealing damages sensitive coffee aromatics and causes film degradation at the seam
- Lack of nitrogen flushing leads to faster oxidation and shorter shelf life
- Inconsistent bag length and positioning on outer wrappers affect packaging line stability
- Non-food-grade materials or parts risk failing food safety audits
Technical Features
- Ultrasonic sealing for inner and outer bags with no heat or adhesive required
- Volumetric cup filling system for 5 to 15 g per bag with consistent weight
- Stepper motor controls outer bag sealing length and positioning with high accuracy
- PID temperature controller for precise heat control during sealing
- PLC control system with human machine interface for easy operation and monitoring

How It Compares
| Single-layer coffee bag machine | The C19D produces both inner and outer bags, offering better protection and a premium look, but requires more setup and space |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids film scorching and maintains film integrity, but requires an air supply and precise control |
| Manual inner and outer bagging | The C19D automates the entire process and ensures consistent weight and seal quality, but needs a fixed power and air supply |
Use Guide
- 1Connect a clean dry air supply and a single phase 220V 50Hz power outlet
- 2Load the inner and outer film rolls matching your chosen bag size and material
- 3Set the volumetric cup to the desired fill weight between 5 and 15 g
- 4Adjust the outer bag sealing length and positioning using the stepper motor controls
- 5Run a test batch of 10 bags and verify fill weight, seal quality, and bag size
- 6Install optional devices like date printer or nitrogen flush connector as needed
