Key Benefits
- Handles whole leaf, flower and root blends that jam machines designed for fine cut or fannings
- Ultrasonic sealing avoids heat and adhesive so aromatics are not scorched at the seam
- 4-head electronic weigher holds fill weight to within +/-0.1 g per bag across the 1 to 10 g range
- Narrow seal edge reduces film consumption compared to wide heat-sealed borders
- Double-layered inner and outer bag provides tamper evidence and better product protection
- One operator can run the line after training instead of a hand-filling team
Application Scenarios
- Tea estates packaging single-origin whole leaf tea in a double-layered pyramid bag for retail
- Herbal and health tea producers running short batches of multiple blends with consistent weight
- Contract packers serving several brands from one line with quick format changeover
- Chinese tea producers exporting Darjeeling Assam or Ceylon blends with branded outer envelopes
Who It Is For
- Tea blenders moving from outsourced packing to in-house double-layered pyramid bagging
- Herbal and health tea producers whose blends are too coarse for flat filter paper bags
- Brands that require visible whole leaf inside a transparent outer envelope for premium positioning
- Buyers replacing an ageing heat-seal machine that damages nylon film or causes seal failure
Problems It Solves
- Coarse whole leaf bridges and jams in machines designed for cut and fannings grades
- Heat sealing melts a wide edge into nylon film and wastes material on every bag
- Hand filling gives inconsistent bag weight and cannot hold a +/-0.1 g target
- Manual pyramid folding limits output far below a 30 to 50 bag per minute requirement
- Single-layer bags fail to provide tamper evidence or adequate protection during transit
Technical Features
- Ultrasonic sealing and cutting with two sealing devices for a tight narrow seam
- 4-head electronic weigher with +/-0.1 g accuracy across the 1 to 10 g range
- Accepts nylon and non-woven filter film imported from Japan plus PET and PLA biodegradable material
- Packing roll width selectable at 120 140 160 or 180 mm
- Seal length selectable at 50 60 70 or 80 mm
- Outer bag size range: length 90 to 120 mm, width 80 to 100 mm
- Runs on single phase 220V 50Hz at 1.5 kW with air supply at 0.6 MPa

How It Compares
| Single-layer pyramid tea bag machine | The C21DX provides a double-layered envelope for tamper evidence and better protection, but requires more film and a larger footprint |
|---|---|
| Heat sealed pyramid machine | Ultrasonic sealing keeps the edge narrow and avoids scorching nylon, at the cost of an air supply requirement |
| Manual pyramid bagging | The C21DX replaces a hand-filling team and holds bag weight consistent, but needs a fixed footprint of 3000 x 900 mm and an operator trained on changeover |
Use Guide
- 1Connect a clean dry air supply at 0.6 MPa and a single phase 220V 50Hz outlet
- 2Load the film roll matched to your chosen 120 140 160 or 180 mm width
- 3Set seal length to 50 60 70 or 80 mm for the bag size you are running
- 4Enter target fill weight between 1 and 10 g and calibrate the electronic scale with your own tea
- 5Run ten sample bags and check weight and seal before starting the batch
- 6Clean the filling hopper between blends to avoid carry-over of aroma
