Key Benefits
- Forms and seals inner and outer bags simultaneously, reducing cycle time compared to sequential machines
- Ultrasonic sealing avoids heat damage to coffee aroma and prevents film scorching on plastic layers
- Volumetric cup filling ensures consistent 5 to 15 g per bag with minimal giveaway across batches
- Stepper motor controls outer bag length positioning for accurate and stable bag size
- PLC control with human machine interface allows quick setup and easy operation by one trained operator
- Supports nitrogen flushing via reserved connector to extend coffee shelf life after packing
Application Scenarios
- Coffee roasters packaging single-origin Liberia beans for direct-to-consumer e-commerce with consistent bag weight and sealed freshness
- Contract packers handling multiple coffee brands with short batch runs and frequent format changes
- Brands launching premium drip coffee bags with hanging ears and visible inner filter paper for retail display
- Packaging teams replacing manual filling and hand-sealing with automated, repeatable performance
Who It Is For
- Coffee roasters moving from outsourced packing to in-house drip coffee bagging
- Contract packers serving multiple coffee brands with different bag sizes and fill weights
- Brands that need a sealed, nitrogen-flush capable system for shelf-stable coffee packaging
- Producers using paper, plastic, or aluminum laminated films and requiring food-safe contact materials
Problems It Solves
- Manual bagging leads to inconsistent fill weight and high labor cost per bag
- Outsourced packing limits control over packaging speed, timing and material choice
- Heat sealing damages delicate coffee oils and can scorch plastic or paper layers
- Inconsistent bag length or seal placement causes rejection during retail or logistics handling
- Lack of nitrogen flushing reduces shelf life for roasted coffee exposed to air after packaging
Technical Features

How It Compares
| Manual coffee bagging | The C19H replaces a hand-filling team and holds fill weight within 5 to 15 g, but requires a fixed footprint of 1200 x 900 mm and trained operator input |
|---|---|
| Heat-sealed coffee bag machine | Ultrasonic sealing avoids film scorching on plastic layers and provides a narrower seal, but requires an air supply and stepper motor control |
| Single-layer bag machine | The C19H forms both inner and outer bags at once, improving efficiency, but uses more film and requires dual film rolls |
Use Guide
- 1Connect a clean dry air supply and single phase 220V 50Hz power outlet
- 2Load the inner and outer film rolls matched to the 180 mm and 200 mm widths
- 3Set the bag size within the 50-75 mm (inner) and 85-120 mm (outer) 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 bag length before starting the batch
- 6Install optional devices such as date printer or nitrogen flushing system as needed
