Key Benefits
- Forms and seals inner and outer bags simultaneously, reducing manual handling and increasing throughput
- Ultrasonic sealing creates a clean, narrow seam without heat or adhesive, preserving coffee aroma and preventing film scorch
- Volumetric cup filling ensures consistent weight across 5 to 15 g per bag, reducing giveaway and waste
- Stepper motor controls outer bag sealing with accurate positioning, reducing misalignment and film waste
- PLC control with human machine interface allows simple operation and quick changeover between formats
- Supports nitrogen flushing via reserved connector to extend shelf life of roasted coffee
- All food contact parts made of SUS304 stainless steel meet food safety standards
Application Scenarios
- Coffee roasters packaging Robusta beans in inner and outer bags for retail or food service distribution
- Contract packers running multiple coffee blends on one line with quick format changeover
- Brands launching new drip coffee products with a sealed inner bag and outer protective layer
- Producers needing to extend shelf life by flushing nitrogen into the outer bag before sealing
Who It Is For
- Coffee roasters transitioning from manual packing to in-house automatic inner and outer bagging
- Contract packers serving multiple coffee brands with different bag sizes and fill weights
- Producers of drip coffee bags who need a sealed inner layer to protect the coffee from moisture and air
- Buyers replacing a single-layer bagging machine with a system that adds an outer protective layer
Problems It Solves
- Manual inner and outer bagging causes inconsistent sealing and high labor costs
- Heat sealing damages delicate coffee oils and can degrade film integrity at the seam
- Inconsistent fill weight leads to overfilling or underfilling, increasing cost and customer complaints
- Lack of nitrogen flushing shortens shelf life of roasted coffee, especially in humid climates
- Poor bag positioning causes misaligned seals and film waste during high-speed operation
- Non-food-grade materials or components risk failing food safety audits
Technical Features
- Ultrasonic sealing for inner and outer bags with no heat or adhesive required

How It Compares
| Single-layer coffee bag machine | The C19H adds an outer protective layer and supports nitrogen flushing, but requires more floor space and a higher initial setup |
|---|---|
| Heat sealed coffee bag machine | Ultrasonic sealing avoids film scorching and maintains a narrow seal, but requires an air supply and is not suitable for all film types |
| Manual inner and outer bagging | The C19H automates both layers and improves consistency, but needs a trained operator and fixed power and air supply |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the selected film roll (180 mm for inner, 200 mm for outer) and align the film path
- 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 sample bags and check fill weight, seal integrity, and positioning before batch start
- 6Use optional date printer or nitrogen flushing connector as needed for product requirements
