HST GK Series (Pot/Mug Size Tea Bags)

HST GK-20 teabag machine for pot and mug size teabags, full view with paper reel and discharge conveyor.

Example: Model GK-33.0

HST GK-20 (Naked Bag)

The GK-20 is used to produce giant-format, heat-sealable single-chamber tea bags. Its extra-large tag (75 x 50 mm visible area) offers an ideal opportunity for eye-catching branding. The bags are not simply tubular, but feature two side longitudinal folds to create more space for the infusion. Furthermore, the longitudinal seal seam is not visible on the full surface of the bag, but is hidden in one of these side folds.

A maximum filling capacity of 5 g / 16 ml is suitable for a teapot. The potential use of polyester mesh allows for a better presentation of products, such as long-leaf teas, herbal or fruit teas. Alternatively, the machine can be equipped with a multihead filling scale or a simpler volumetric dosing system for finely cut teas. Production runs via a conveyor belt with a flexible counter to separate groups of tea bags for easier removal and handling.

The machine produces up to 45-60 bags per minute.


HST GK-33 (Bag in Heat-Sealed Envelope)

The GK-33 is based on the GK-20 and produces the same type of tea bags. However, in this model, each tea bag is wrapped in an airtight, heat-sealed outer foil to protect the aroma. If a transparent foil is used in combination with mesh filter material, the packaged product can be perfectly presented to the consumer.
The foil roll transport can optionally be equipped with a thermal transfer printer to mark the foil, e.g., with a best-before date and a batch number or even with a product label.
