Type HST PT-33 (tea bag in heat-sealed outer packaging)
Example: Model PT-2.33.0 (Handheld version)
Basics: PT-y.33
The effective HST machine type PT-33 produces non-heat-sealable double-chamber tea bags with an outer airtight foil envelope. It is based on our proven basic platform machine PT-21 and can produce 150 to 160 bags per minute.
The bag comes with a string and a fixed tag, optionally knotted or stapled:
PT-2.33 : With knotting technology on both sides, both on the tag side and on the bag side (i.e. y=2).
PT-1.33 : Knotting only on the bag side (i.e. y=1),
PT-0.33 : With standard food-grade aluminum staples (i.e. y=0).
These bags are then individually wrapped in an outer foil envelope by sealing the seams on 3 sides, with a wide range of materials from oriented polypropylene (OPP), cellophane, PLA, paper composites (with aluminum or PE and the like).
The foil roll transport can optionally be equipped with a thermal transfer printer to label the foil, e.g. with a best-before date and a batch number or even with a product description.
The PT-y.33.0 version (manual packing version) can optionally be equipped so that it can be converted from an envelope to a naked bag (corresponding to the PT-y.21.0 manual packing).
The PT-33 has several advantages: The tea bag is completely aroma-proof, protected in both directions. The envelopes are completely wrinkle-free because the tea bag lies horizontally during heat sealing. The consumption of environmental resources can be optimized, as the PT-33 can even process foils up to a thickness of 35 µm. The machine is therefore not only reliable, but also very economical, as it produces at reasonable costs.
Bag size options: A | B
The following tea bag sizes are possible:
A : Larger bag size 64 x 44 mm.
Due to the larger volume, this is the best choice for packaging herbal and fruit teas.
B : Smaller bag size 60 x 40 mm.
This is the standard for packaging black tea.
The machines cannot be converted to other bag sizes.
Packaging options: PT-y.33. 0 | 1 | 2
The following packaging options are available:
PT-y.33.0 : Manual packaging machine (hand pack).
Where high flexibility is required or in countries where labor costs are lower, these manual packaging versions are very popular. These models are equipped with an automatic counter that counts, stacks, and conveys the bags into an exit chute. These stacked and pre-counted bags can then be manually removed and filled into pre-formed boxes or tins.
PT-y.33.1 : Single-row cartoning device.
Pre-glued tray boxes, adjustable between 15 and 30 bags.
Machines with automatic single-row cartoning are used by companies with a high level of automation and with special production lines for a specific box format.
PT-y.33.2 : Multi-row cartoning machine.
Flat blank boxes for up to 100 tea bags. This complex cartoning is used in the rarer cases of large packs.

Frequently Asked Questions
How many tea bags does the HST PT-33 produce per minute?
The PT-33 is based on the PT-21 platform and produces 150 to 160 non-heat-sealable double-chamber tea bags per minute.
How is the tea bag packed?
Each bag is individually packed in an airtight foil envelope that is sealed on three sides. This keeps the tea aroma-tight in both directions. The envelopes are wrinkle-free because the bag lies horizontally during heat sealing.
Which films can the PT-33 process?
A wide range of materials: oriented polypropylene (OPP), cellophane, PLA and paper laminates, for example with aluminium or PE. The machine processes films with a thickness of down to 35 µm.
Can the film be printed?
The film reel transport can optionally be equipped with a thermal transfer printer, for example for the best-before date, batch number or product marking.
Which bag sizes are possible?
Format A measures 64 x 44 mm and is best suited for herbal and fruit tea. Format B measures 60 x 40 mm and is the standard for black tea. A machine cannot be converted to a different bag size.
