Key Benefits
- Produces inner and outer bags simultaneously to double packing speed compared to sequential machines
- Ultrasonic sealing avoids heat damage so coffee aroma is not altered at the seam
- Volumetric cup filling holds 5 to 15 g per bag with consistent weight across the batch
- Narrow seal edge reduces film waste and improves bag appearance
- PLC control with human machine interface allows quick setup and easy operation
- Stainless steel food contact parts ensure compliance with food safety standards
Application Scenarios
- Coffee roasters packaging single-origin Arabica powder for retail or wholesale in sealed inner and outer bags
- Contract packers handling multiple coffee brands with short batch runs and quick format changes
- Packaging facilities needing nitrogen flushing to extend shelf life of roasted coffee
- Brands requiring a visible inner bag with a durable outer layer for retail display
Who It Is For
- Coffee roasters replacing manual or semi-automatic packing with in-house automation
- Contract packers serving multiple coffee brands with different bag sizes and film types
- Producers who need nitrogen flushing to preserve freshness in sealed coffee bags
- Packaging teams moving from heat-sealed to ultrasonic sealing to avoid film scorching
Problems It Solves
- Manual packing of inner and outer bags is slow and inconsistent in fill weight
- Heat sealing damages delicate coffee powder and can scorch film at the seal edge
- Sequential inner and outer bag machines reduce output and increase floor space use
- Lack of nitrogen flushing leads to faster oxidation and shorter shelf life
- Inconsistent bag size and seal position from mechanical misalignment
Technical Features
- Ultrasonic sealing for inner and outer bags with two sealing devices
- Volumetric cup filling for 5 to 15 g per bag with consistent weight
- Stepper motor controlled outer bag sealing for accurate positioning
- PID temperature controller for stable heating in the sealing zone
- PLC control system with human machine interface for easy operation
- All food contact parts made of SUS304 stainless steel
- Optional flat cut, date printer, easy tear device, and nitrogen flush connector
- High specification components including imported cylinders for stable performance

How It Compares
| Sequential inner and outer bag machine | The C19D packs both bags at once, reducing cycle time and floor space, but requires a wider film roll |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids film scorching and maintains aroma, but requires an air supply for sealing |
| Manual bagging with hand sealers | The C19D replaces a team of packers and holds fill weight consistently, but needs a fixed power and air supply |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the film roll matched to your chosen inner and outer bag size and film type
- 3Set inner and outer bag dimensions on the PLC interface to match your bag size
- 4Calibrate the volumetric cup filler with your coffee powder to target 5 to 15 g per bag
- 5Run ten test bags and check fill weight, seal integrity, and bag position before starting the batch
- 6Install optional devices like date printer or nitrogen flush connector if needed
