Key Benefits
- Produces inner and outer bags simultaneously, cutting packaging time in half compared to sequential machines
- Ultrasonic sealing creates strong, clean seams without heat or glue, preserving coffee aroma and preventing film scorch
- Volumetric cup filling ensures consistent 5 to 15 g per bag with minimal giveaway across batches
- Stepper motor control for outer bag sealing delivers accurate positioning and stable bag length
- SUS304 stainless steel parts in food contact zones meet food safety standards and resist corrosion
- Reserved connector for nitrogen flushing extends coffee shelf life by reducing oxidation
Application Scenarios
- Coffee roasters packaging single-origin Arabica in retail-ready inner and outer bags for direct-to-consumer sales
- Contract packers handling short runs of multiple coffee blends with quick format changeover
- Brands requiring a clean, professional look with sealed outer bags and visible inner coffee
- Producers adding nitrogen flushing to extend shelf life for export or long-term storage
Who It Is For
- Coffee roasters transitioning from outsourced packaging to in-house production
- Contract packers serving multiple coffee brands with different bag sizes and formats
- Retailers and distributors needing consistent bag weight and sealed freshness
- Producers who require nitrogen flushing to preserve coffee quality during shipping
Problems It Solves
- Manual inner and outer bag packaging is slow and inconsistent in weight and seal quality
- Heat sealing damages coffee aroma and can scorch film, especially on thin plastic layers
- Inconsistent bag length and positioning lead to misaligned labels and poor shelf appearance
- Lack of nitrogen flushing results in faster coffee oxidation and shorter shelf life
- Non-stainless steel parts in food contact zones risk contamination and fail safety audits
Technical Features
- Ultrasonic sealing for inner and outer bags with no heat or adhesive required
- Stepper motor control for precise outer bag sealing and consistent bag length
- PID temperature controller for accurate and stable heating in sealing zones
- PLC control system with human machine interface for simple operation and monitoring
- Volumetric cup filling system for 5 to 15 g per bag with consistent output
- Reserved connector for nitrogen flushing to extend coffee shelf life

How It Compares
| Sequential inner and outer bag machine | The C19D makes both bags at once, reducing cycle time and labor, but requires a single integrated film feed |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids film scorch and maintains film integrity, but requires an air supply and more precise alignment |
| Manual bagging line | The C19D replaces a team of packers and ensures consistent weight and seal quality, but needs a fixed 1200 x 900 mm floor space and trained operator |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz outlet with 3.7 kW capacity
- 2Load the inner and outer film rolls matching the 180 mm and 200 mm width specifications
- 3Set bag length and width on the PLC interface to match the desired inner and outer bag size
- 4Calibrate the volumetric cup filler with your coffee blend to achieve 5 to 15 g per bag
- 5Run 10 test bags and check fill weight, seal quality, and bag alignment before batch start
- 6Install optional devices like date printer or nitrogen flush connector as needed
