- Photoelectric positioning ensures consistent tag placement on every bag
- Volumetric cup filling delivers repeatable 3 to 15 ml per bag with minimal giveaway
- Adjustable inner and outer bag sizes allow quick changeover between formats
- Outer envelope protects the inner bag from moisture and light during storage
- Thread and tag attachment is optional, so the machine fits both simple and premium packaging needs
Application Scenarios
- Herbal tea producers packaging loose leaf blends in a sealed outer envelope for retail and export
- Medicinal tea manufacturers needing a hygienic, automated solution for small granular products
- Health tea brands launching new product lines with branded outer envelopes and tags

How It Compares
| Single inner bag machine | The C18 adds an outer envelope for protection and premium appearance, but requires more film and setup time |
|---|---|
| Manual inner and outer bag assembly | The C18 automates the entire process and ensures consistent seal and tag placement, but needs a fixed power and air supply |
| Heat-sealed flat bag machine | The C18 handles multi-layer envelopes and tag attachment, but is not designed for pyramid or hanging bag formats |
Use Guide
- 1Connect a clean dry power supply at 220V 50Hz and ensure the 3.7 kW motor is supported
- 2Load the inner filter paper and outer composite film rolls according to the chosen 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 to 15 ml and calibrate with the customer's product
- 5Enable photoelectric positioning and align the tag sensor to the desired position
- 6Run ten test bags and verify fill volume, seal integrity, and tag placement before batch start
