Key Benefits
- Automatically produces inner and outer bags in one cycle, reducing manual handling and increasing output
- Volumetric cup filling delivers consistent fill weight across 5 to 15 g per bag without relying on gravity or augers
- Ultrasonic sealing on both inner and outer layers ensures a tight, clean seal without heat or adhesive
- Stepper motor controls outer bag length positioning for accurate and repeatable bag sizing
- PLC control with human machine interface allows easy setup and monitoring of production parameters
- SUS304 stainless steel parts in food contact zones meet food safety standards and resist corrosion
Application Scenarios
- Coffee roasters packaging single-origin Arabica beans in drip bags for direct-to-consumer or retail sale
- Contract packers running multiple coffee blends on one line with quick format changeover
- Roasters needing to extend shelf life by integrating nitrogen flushing into the packaging process
- Brands requiring a printed outer bag with date code, brand logo and product information on every unit
Who It Is For
- Coffee roasters transitioning from manual packing to automated inner and outer bagging
- Contract packers serving multiple coffee brands with different bag sizes and print requirements
- Producers of premium drip coffee who need a sealed inner layer to protect aroma and freshness
- Buyers replacing older machines that cannot handle multi-layer bag formats or nitrogen flushing
Problems It Solves
- Manual inner and outer bagging leads to inconsistent fill weight and high labor cost
- Heat sealing damages coffee aroma and can degrade film integrity on sensitive materials
- Inconsistent bag length or positioning causes misalignment in downstream printing or packing
- Lack of nitrogen flushing results in faster oxidation and shorter shelf life for roasted coffee
- Older machines cannot run both inner and outer bags simultaneously, slowing down production
Technical Features
- Ultrasonic sealing on both inner and outer bags with two independent sealing stations
- Stepper motor controls outer bag length positioning for accurate and stable bag sizing
- PID temperature controller for precise heat management during sealing operations
- Volumetric cup filler ensures consistent fill weight across 5 to 15 g per bag
- PLC control system with human machine interface for intuitive operation and monitoring
- All food contact parts made of SUS304 stainless steel for durability and hygiene
- Optional devices include flat cut, date printer, easy tear feature, and nitrogen flushing connector

How It Compares
| Single-layer coffee bag machine | The C19D handles both inner and outer bags in one cycle, improving protection and shelf life, 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 alignment |
| Manual bagging line | The C19D replaces a hand-filling team and ensures consistent fill weight and seal quality, but needs a fixed 1200 x 900 mm footprint and trained operator |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load inner and outer film rolls matched to your chosen bag size and material
- 3Set inner and outer bag dimensions using the control panel for 50-75 mm and 85-120 mm lengths
- 4Enter target fill weight between 5 and 15 g and calibrate the volumetric cup filler with your coffee
- 5Run ten sample bags and check fill weight, seal integrity, and bag length before batch start
- 6Use optional devices like date printer or nitrogen flush connector as needed for branding or shelf life
