Key Benefits
- Produces inner and outer bags simultaneously, cutting packaging time in half compared to sequential machines
- Ultrasonic sealing creates a tight, clean seal without heat or adhesive, preserving coffee aroma and preventing film scorching
- Volumetric cup filling ensures consistent 5 to 15 g per bag with minimal giveaway across batches
- PLC control with human machine interface allows quick setup and easy operation by one trained operator
- All food contact parts are made of SUS304 stainless steel, meeting food safety standards for direct product contact
- Built-in nitrogen flush connector allows integration with a nitrogen generator to extend shelf life
Application Scenarios
- Coffee roasters packaging small-batch single-origin Arabica for direct-to-consumer e-commerce
- Contract packers handling multiple coffee brands with short batch runs and frequent format changes
- Roasteries upgrading from manual bagging to automated inner and outer bag sealing for retail-ready packaging
- Packaging facilities needing nitrogen flushing to maintain freshness for premium coffee in sealed bags
Who It Is For
- Coffee roasters transitioning from manual packing to automated inner and outer bag sealing
- Contract packers serving multiple coffee brands with different bag sizes and packaging needs
- Retail coffee brands requiring consistent fill weight and professional packaging for shelf appeal
- Producers who need nitrogen flushing to extend shelf life without adding preservatives
Problems It Solves
- Manual inner and outer bag sealing slows production and increases labor cost per bag
- Inconsistent fill weight from hand scooping leads to customer complaints and brand reputation risk
- Heat sealing damages coffee oils and can scorch film, especially on high-temperature sensitive Arabica beans
- Lack of nitrogen flushing leads to faster oxidation and reduced shelf life for roasted coffee
- Poor seal integrity causes leaks and product loss during shipping and storage
Technical Features
- Ultrasonic sealing for inner and outer bags with two sealing devices for consistent closure
- Volumetric cup filling system for 5 to 15 g per bag with stable and repeatable output

How It Compares
| Manual inner and outer bag sealing | The C19D replaces a team of packers and ensures consistent fill weight and seal quality, but requires a fixed floor space of 1200 x 900 mm and trained operator |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids film scorching and maintains aroma, but requires an air supply and more precise maintenance |
| Single inner bag machine | The C19D produces both inner and outer bags at once, improving efficiency, but requires wider film rolls and more complex setup |
Use Guide
- 1Connect a clean dry air supply and 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 length using the stepper motor control for consistent positioning
- 5Run 10 test bags and verify fill weight, seal integrity, and bag size before full batch
- 6Enable optional features like date printing or nitrogen flush if required
