Name: HST - PT 33
Brand: HST

Question 1

What is the HST PT 33 teabag machine?

Accepted Answer

A double-chamber teabag machine that makes string-and-tag bags in aroma-protective heat-sealed envelopes, at up to 165 bags per minute. This helps buyers assess aroma protection, format compatibility and downstream packing requirements before ordering.

Question 2

How fast is the PT 33?

Accepted Answer

The HST PT 33 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 retail-ready output from one line.

Question 3

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), enveloped. This helps buyers assess aroma protection, format compatibility and downstream packing requirements before ordering.

Question 4

Does it envelope the teabags?

Accepted Answer

Yes—each double-chamber bag is sealed in an aroma-protective envelope. This helps buyers assess aroma protection, format compatibility and downstream packing requirements before ordering.

Question 5

Does it use knotting or staples?

Accepted Answer

Both—the PT 33 supports knotting or staples for tag attachment. This helps buyers assess aroma protection, format compatibility and downstream packing requirements before ordering.

Question 6

Can it carton the bags?

Accepted Answer

Yes — optional single-row or multi-row cartoning is available on the HST PT 33, 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 7

PT 33 vs PT 25 — which should I choose?

Accepted Answer

Both make enveloped double-chamber bags; the PT 33 uses aroma-protective heat-sealed envelopes, while the PT 25 uses sustainable crimped paper envelopes.

Question 8

What is a double-chamber teabag?

Accepted Answer

A double-chamber teabag is a bag folded into two connected compartments, which allows greater water flow through the tea and a faster, more complete infusion compared with a standard flat single-chamber bag. The format is preferred for premium loose-leaf teas, blended herbals and botanicals, and any product where infusion speed and clarity of flavour are important. In Middle Eastern and South Asian markets, the double-chamber bag with string and tag is the dominant format for branded retail tea.

Question 9

Is it good for premium tea?

Accepted Answer

Yes — the PT 33's aroma-protective heat-sealed envelope creates an air-tight seal around each double-chamber bag, preserving volatile aromatic compounds from packing to the consumer's cup. This format is the benchmark for premium-positioned teas in Middle Eastern, European and Asian retail environments, where freshness claims and unboxing presentation are both important to the buyer. The string-and-tag format further reinforces a premium, traditional appearance.

Question 10

Who makes the PT 33?

Accepted Answer

The HST PT 33 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.
