Key Benefits
- Forms inner and outer bags simultaneously to reduce operator contact with packing materials
- Photoelectric positioning ensures tag and outer bag align correctly on every bag
- Volumetric cup filling delivers consistent fill volume between 3 and 15 ml per bag
- Adjustable inner and outer bag sizes to match different product formats and branding needs
- Thread and tag attachment is optional, allowing flexible configuration for different markets
- One operator can manage the line after training, replacing a manual packing team
Application Scenarios
- Tea blenders packaging small granular blends in a two-layer bag with a visible tag for retail or gift sets
- Herbal and health-tea producers running short batches of multiple formulas with consistent branding
- Contract packers handling multiple private-label tea brands from one machine with quick format changeover

How It Compares
| Manual inner and outer bagging | The C18 replaces a hand-filling team and ensures consistent fill volume and tag alignment, but requires a fixed footprint of 1250 x 700 mm and an operator trained on changeover |
|---|---|
| Single-layer filter paper tea bag machine | The C18 provides a two-layer structure with a visible tag and outer envelope, improving product appearance and protection, but uses more film and requires more setup time |
| Heat sealed flat bag machine | The C18 handles small granular blends without bridging, while flat bag machines may struggle with uneven flow and inconsistent fill |
Use Guide
- 1Connect a clean dry air supply at 0.6 MPa and a single phase 220V 50Hz outlet
- 2Load the filter paper roll for the inner bag and composite film for the outer bag
- 3Set inner and outer bag dimensions to match your product size and branding
- 4Adjust tag size and position using the photoelectric sensor settings
- 5Enter target fill volume between 3 and 15 ml and calibrate the volumetric cup with your own tea
- 6Run ten sample bags and check fill volume, seal integrity and tag alignment before starting the batch
- 7Clean the filling cup and sealing area between product changes to avoid cross-contamination
