Key Benefits
- Ultrasonic sealing creates a narrow, strong seal without heat or adhesive, preserving aroma and preventing film scorching
- Volumetric cup filling ensures consistent 5 to 15 g per bag with minimal giveaway across batches
- Inner and outer bag formed and sealed in one continuous process, reducing manual handling and increasing throughput
- PLC control with human machine interface allows simple setup and real-time monitoring of fill weight and sealing parameters
- SUS304 stainless steel parts in food contact zones meet food safety standards and resist corrosion
- Built-in connector for nitrogen flushing extends shelf life by reducing oxidation in the sealed bag
Application Scenarios
- Coffee roasters packaging small-batch single-origin beans for direct-to-consumer or retail sale
- Contract packers running multiple coffee brands on one line with quick format changeover
- Roasters transitioning from manual bagging to in-house automatic packaging with consistent fill weight
- Brands requiring a premium look with a sealed outer bag and visible inner filter bag
Who It Is For
- Coffee roasters moving from outsourced packing to in-house automatic bagging
- Contract packers serving multiple coffee brands with short batch runs
- Roasters who need nitrogen flushing to extend shelf life without adding extra equipment
- Packaging teams replacing manual or semi-automatic systems with a fully integrated solution
Problems It Solves
- Manual inner and outer bagging leads to inconsistent fill weight and poor seal quality
- Heat sealing damages delicate coffee oils and can cause film degradation at the seam
- Separate machines for inner and outer bagging increase floor space and complexity
- Lack of nitrogen flushing shortens shelf life of roasted coffee in ambient conditions
- Inconsistent bag size and seal position reduce brand consistency and customer trust
Technical Features

How It Compares
| Manual inner and outer bagging | The C19D replaces a hand-filling team and ensures consistent fill weight and seal quality, but requires a fixed 1200 x 900 mm footprint and trained operator |
|---|---|
| Heat sealed coffee bag machine | Ultrasonic sealing avoids film scorching and creates a narrower seal, but requires an air supply and higher initial component cost |
| Separate inner and outer bag machines | The C19D combines both processes into one line, reducing floor space and complexity, but is limited to the specified bag size range |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the selected film roll matching the 180 mm inner or 200 mm outer bag width
- 3Set inner and outer bag size within the 50-75 mm and 85-120 mm range using the control panel
- 4Enter target fill weight between 5 and 15 g and calibrate the volumetric cup with your coffee
- 5Run ten test bags and verify weight, seal quality, and bag positioning before batch start
- 6Clean the volumetric cup and sealing heads between different coffee types to avoid aroma carry-over
