C88DX Automatic Inner and Outer Black Tea Bag Filling Machine

The C88DX forms, fills and ultrasonically seals inner and outer tea bags from a single roll of nylon or non-woven film, running 35 to 55 bags per minute at 1 to 10 g per bag. It is built for tea blenders and packers who need to automate the packaging of loose leaf, herbal, health, and floral teas including Darjeeling, Assam, and Ceylon. The machine uses a 6-head electronic weigher for consistent fill weight and two ultrasonic sealing devices to create a tight, narrow seal without heat or adhesive. It supports both pyramid and flat bag formats with a 90 to 120 mm length and 80 to 100 mm width outer bag size.

Handles coarse whole leaf and delicate flower blends that jam mechanical fillers on flat bag machines
Ultrasonic sealing avoids heat damage and preserves aroma, unlike hot-melt methods
6-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 waste compared to wide heat-sealed borders

Key Benefits

Handles coarse whole leaf and delicate flower blends that jam mechanical fillers on flat bag machines
Ultrasonic sealing avoids heat damage and preserves aroma, unlike hot-melt methods
6-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 waste compared to wide heat-sealed borders
One operator can manage the line after training, replacing a hand-filling team
Quick changeover between pyramid and flat bag formats without machine reconfiguration

Application Scenarios

Tea blenders packaging single-origin loose leaf tea for retail under their own brand
Herbal and health tea producers running short batches of multiple blends with consistent weight
Contract packers serving several tea brands from one machine with fast format switching
Export-focused producers needing compliant packaging for international markets with visible leaf content

Who It Is For

Tea blenders transitioning from outsourced packing to in-house automation
Producers of floral and herbal teas whose ingredients are too coarse for flat filter bags
Brands requiring the leaf visible through a transparent bag with a clean, narrow seal
Buyers replacing an older machine that uses heat sealing and causes film scorching

Problems It Solves

Coarse whole leaf and flower blends bridge and jam in machines designed for fine cut tea
Heat sealing melts a wide edge into nylon film and wastes material on every bag
Hand filling results in inconsistent bag weight and cannot meet a +/-0.1 g target
Manual inner and outer bag assembly limits output below 35 to 55 bags per minute
Non-food-grade film risks failing safety audits from retailers and regulatory bodies

How It Compares

Flat filter paper tea bag machine	The C88DX handles coarse whole leaf and shows the blend through the film, while filter paper suits fine cut and fannings at lower film cost
Heat sealed pyramid machine	Ultrasonic sealing keeps the edge narrow and avoids scorching nylon, at the cost of an air supply requirement
Manual inner and outer bag assembly	The C88DX replaces a hand-filling team and holds bag weight consistent, but needs a fixed footprint of 2000 x 1350 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
