Key Benefits
- Forms and seals inner and outer bags simultaneously, doubling throughput compared to sequential machines
- Ultrasonic sealing creates a narrow, strong seam without heat or adhesive, preserving coffee aroma
- Volumetric cup filling ensures consistent 5 to 15 g per bag with minimal giveaway
- Stable stepper motor control for precise bag length positioning and repeatable sealing
- Built-in nitrogen flush port allows connection to a nitrogen generator to extend shelf life
- PLC control with human machine interface enables simple operation and quick format changeover
Application Scenarios
- Coffee roasters packaging Robusta and specialty blends in sealed drip bags for retail and food service
- Contract packers running multiple coffee brands on one line with quick bag size and film changes
- Brands launching compostable or biodegradable coffee bags using PLA or paper-based films
- Producers needing to extend shelf life by flushing nitrogen into each bag during packaging
Who It Is For
- Coffee roasters moving from manual packing to in-house automated drip bagging
- Contract packers serving multiple coffee brands with short batch runs and varied bag sizes
- Sustainable brands requiring compostable or recyclable packaging with a clean seal
- Buyers replacing older machines that use heat sealing and produce wide waste edges
Problems It Solves
- Manual inner and outer bag assembly limits output and causes inconsistent sealing
- Heat sealing damages delicate coffee oils and creates a wide waste edge on every bag
- Inconsistent fill weight leads to customer complaints and increased giveaway costs
- Lack of nitrogen flushing results in faster oxidation and shorter shelf life for roasted coffee
- Non-food-grade materials or poor sealing integrity risk product contamination and audit failure
Technical Features
- Ultrasonic sealing for narrow, strong seams without heat or adhesive
- Volumetric cup filling for consistent 5 to 15 g per bag with repeatable accuracy
- Stepper motor control for precise bag length positioning and stable sealing
- PID temperature controller for accurate heat control during sealing
- PLC control system with human machine interface for easy operation and monitoring
- All food-contact parts made of SUS304 stainless steel for hygiene and durability

How It Compares
| Sequential inner and outer bag machine | The C19D forms and seals both bags at once, improving throughput and reducing floor space, but requires a single film roll with pre-cut inner and outer layers |
|---|---|
| Heat-sealed drip bag machine | Ultrasonic sealing avoids scorching and creates a narrower seam, but requires an air supply and is not suitable for all film types |
| Manual bagging line | The C19D replaces a team of packers and ensures consistent fill and seal, but requires a fixed 1200 x 900 mm footprint and trained operator |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz outlet with 3.7 kW capacity
- 2Load the film roll matching your chosen inner and outer bag size and film type
- 3Set the bag length using the stepper motor control for consistent positioning
- 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 strength, and bag size before batch start
- 6Use the reserved connector to link to a nitrogen generator if extending shelf life is required
