Key Benefits
- Forms inner and outer tea bags at the same time, reducing handling and contamination risk
- Photoelectric positioning ensures the tag is aligned correctly on every outer bag
- Adjustable inner and outer bag sizes to match different product formats and branding needs
- Volumetric cup filling delivers consistent fill volume across batches without manual adjustment
- Thread and tag attachment is optional, allowing flexibility for different packaging standards
- Uses filter paper for inner bags and composite film for outer envelopes to meet shelf-life and barrier requirements
Application Scenarios
- Tea blenders packaging black tea in branded inner and outer bags with a visible thread and tag
- Contract packers running multiple tea blends with different bag sizes on one machine
- Health tea producers requiring a sealed outer envelope to protect delicate blends from moisture
- Brands launching premium tea lines where the outer envelope enhances product presentation
Who It Is For
- Tea blenders moving from hand packing to in-house automatic inner and outer bagging

How It Compares
| Manual inner and outer tea bagging | The C18 replaces hand assembly, reduces contamination risk, and ensures consistent tag alignment, but requires a fixed floor space of 1250 x 700 mm and trained operator |
|---|---|
| Single inner bag machine | The C18 adds an outer envelope for protection and branding, but requires more film input and setup time for dual bag formation |
| Heat sealed flat bag machine | The C18 handles multi-layered outer envelopes with better barrier properties, but uses more material and has a larger footprint |
Use Guide
- 1Connect a single phase 220V 50Hz power supply with 3.7 kW capacity
- 2Load the inner and outer film rolls according to the selected material type
- 3Set inner bag size to 50-70 mm length and 40-80 mm width, outer bag to 70-120 mm length and 60-90 mm width
- 4Adjust the volumetric cup to 3-15 ml fill volume and calibrate with your tea blend
- 5Enable photoelectric positioning for tag alignment and test with sample bags
- 6Run ten test bags and verify fill volume, tag position, and seal integrity before batch production
