C88DX Triangle Rooibos Tea Filling Machine with Outer Envelope

The C88DX forms, fills and ultrasonically seals triangle-shaped inner and outer tea bags from a single roll of nylon, non-woven, PET or PLA film, running 35 to 55 bags per minute at 1 to 10 g per bag. It is built for tea producers and blenders who need to package whole leaf, herbal, and specialty teas like Darjeeling, Assam, and Ceylon in a visible, secure, and hygienic format. Two ultrasonic sealing devices create a tight, narrow seal without heat or adhesive, reducing material waste and preserving delicate aromatics. The 6-head electronic weigher ensures fill accuracy within +/-0.1 g per bag.

Handles whole leaf, flower, and coarse herbal blends that jam auger fillers on flat bag machines
Ultrasonic sealing avoids heat and adhesive so delicate tea aromatics are not scorched at the seam
Electronic scale filling holds +/-0.1 g accuracy per bag across the 1 to 10 g range
Narrow seal edge reduces film consumption compared to wide heat-sealed borders

Key Benefits

Handles whole leaf, flower, and coarse herbal blends that jam auger fillers on flat bag machines
Ultrasonic sealing avoids heat and adhesive so delicate tea aromatics are not scorched at the seam
Electronic scale filling holds +/-0.1 g accuracy per bag across the 1 to 10 g range
Narrow seal edge reduces film consumption compared to wide heat-sealed borders
One operator can run the line after training instead of a hand-filling team
Roll width and seal length change over to multiple bag formats without a new machine

Application Scenarios

Tea estates packaging single-origin whole leaf rooibos and specialty teas for retail under their own label
Herbal and health tea producers running short batches of many different blends with quick changeover
Contract packers serving multiple tea brands from one line with consistent fill weight and seal quality
Coffee roasters and tea blenders expanding into pyramid bagging for premium loose leaf products

Who It Is For

Tea blenders moving from outsourced packing to in-house triangle bagging
Herbal tea producers whose leaf is too coarse for flat filter paper bags
Brands that need the leaf visible through a transparent biodegradable bag
Buyers replacing an ageing heat-seal machine that scorches nylon film

Problems It Solves

Coarse whole leaf bridges and jams in machines designed for cut and fibre 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 35 to 55 bag per minute demand
Non-food-grade film risks failing customer and retailer safety audits

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 pyramid bagging	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
