Key Benefits
- Inner and outer bag formed simultaneously to reduce handling and contamination risk
- Photoelectric positioning ensures tag and thread are aligned consistently on every bag
- Volumetric cup filling delivers repeatable 3 to 15 ml per bag without manual adjustment
- Outer envelope improves product presentation and protects the inner bag during transport
- Adjustable inner and outer bag sizes allow quick changeover between formats
- Thread and tag attachment is optional, so the machine can run without them if needed
Application Scenarios
- Herbal tea producers packaging ginseng, chrysanthemum and goji berry blends in a branded outer envelope
- Health-tea brands running short runs of multiple formulas with consistent tag placement
- Tea blenders moving from hand packing to in-house automatic bagging with a clean, sealed outer layer
- Contract packers serving several private label brands from one machine with quick format changeover
Who It Is For
- Tea blenders who need a branded outer envelope for retail or gift packaging

- Brands that want a professional finish with a visible thread and tag on every bag
- Buyers replacing a manual packing line that cannot hold consistent fill volume or tag alignment
Problems It Solves
- Manual inner and outer bag assembly causes inconsistent fill volume and tag misalignment
- Exposure to packing materials during hand filling risks contamination and hygiene issues
- Lack of outer envelope reduces product protection and perceived value in retail
- Inconsistent tag placement makes the product look unprofessional on shelves
- No photoelectric positioning leads to misaligned tags and rejected bags in high-speed runs

How It Compares
| Manual inner and outer bag assembly | The C18 replaces hand packing with consistent fill volume and tag alignment, but requires a fixed footprint of 1250 x 700 mm and an operator trained on changeover |
|---|---|
| Flat bag machine with no outer envelope | The C18 adds a protective outer layer and branded presentation, but uses more material and requires more setup time |
| Single inner bag machine | The C18 forms both inner and outer bags at once, reducing handling, but needs a larger machine footprint and more power |
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 envelope
- 3Set inner and outer bag dimensions to match your product size using the machine controls
- 4Enter target fill volume between 3 and 15 ml and calibrate the volumetric cup with your product
- 5Run ten sample bags and check fill volume, seal integrity, and tag alignment before starting the batch
- 6Clean the filling cup and forming guides between product changes to avoid carry-over
