Name: HST - PT 25
Brand: HST

Question 1

What is the HST PT 25 teabag machine?

Accepted Answer

A double-chamber teabag machine that makes string-and-tag bags in crimped paper envelopes—a sustainable, hygienic format—at up to 165 bags per minute. This helps buyers assess the paper-envelope format, required automation and line integration before ordering.

Question 2

How fast is the PT 25?

Accepted Answer

The HST PT 25 runs at up to 165 bags per minute under normal production conditions. That equals approximately 9,900 enveloped double-chamber teabags per hour; the tea throughput in kilograms depends on the specified filling weight. For a mid-size factory running two shifts, this provides substantial paper-envelope output from one line.

Question 3

What envelope does it use?

Accepted Answer

A crimped paper envelope, a sustainable and hygienic alternative to foil. This helps buyers assess the paper-envelope format, required automation and line integration before ordering.

Question 4

What bag formats does it make?

Accepted Answer

Double-chamber bags in formats A (44×64 mm), B (40×60 mm) and D (44×60 mm). This helps buyers assess the paper-envelope format, required automation and line integration before ordering.

Question 5

PT 25 vs PT 33 — which should I choose?

Accepted Answer

The PT 25 uses eco-friendly crimped paper envelopes; the PT 33 uses aroma-protective heat-sealed envelopes. Both make double-chamber string-and-tag bags.

Question 6

Does it use knotting or stapling?

Accepted Answer

Both are available—the finishing type is selected by order. This helps buyers assess the paper-envelope format, required automation and line integration before ordering.

Question 7

Is it a sustainable option?

Accepted Answer

Yes — the PT 25's crimped paper envelope is made from paper rather than foil or plastic laminate, making it the more sustainable choice of the enveloped double-chamber formats. Crimped paper envelopes are increasingly specified by retailers, especially in the EU and UK, as brands respond to packaging sustainability requirements and consumer demand for less plastic. For tea producers supplying European or premium Middle Eastern retail, specifying the PT 25 can support packaging claims without sacrificing protection or presentation quality.

Question 8

Can it carton the bags?

Accepted Answer

Yes — optional single-row or multi-row cartoning is available on the HST PT 25, packing finished bags into cartons as part of the line. Manual, single-row and multi-row configurations are available at order. This integration removes a separate cartoning step, reducing footprint and labour for branded retail production.

Question 9

Is it energy-efficient?

Accepted Answer

Yes — the HST PT 25 and PT 25.1 consume approximately 0.65 kWh, which is low for output of up to 165 bags per minute. All models run on standard compressed air at 4–6 bar; the multi-row PT 25.2 uses 4.25 kWh because it includes integrated cartoning. For tea factories in the Middle East, this balance of output and utility demand supports a favourable cost per finished bag.

Question 10

Who makes the PT 25?

Accepted Answer

The HST PT 25 is manufactured by HST Maschinenundlagen GmbH, a German specialist in tea and herbal infusion packaging machinery with decades of experience supplying production lines to the global tea industry. HST machines are installed in tea factories across Europe, Asia and the Middle East. In the Gulf, India and surrounding markets, HST machines are represented and supported by dph Industries, which handles technical consultancy, commissioning and regional after-sales service.
