HST PT-25 Type (Tea bag in a paper envelope)
Example: Model PT-2.25.1 (Belt Packaging)
The basics: PT-y.25
The widely sold HST PT-25 machine produces non-heat-sealable double-chamber tea bags with an outer paper envelope. It is based on our proven HST PT-21 base platform machine and can produce 150 to 165 bags per minute.
The bag comes with a string and a fixed tag, either knotted or stapled:
PT-2.25 : With knotting technology on both sides, on the tag side as well as on the bag side (i.e. y=2).
PT-1.25 : Knotting on the bag side only (i.e. y=1).
PT-0.25 : With standard food-grade aluminium staples (i.e. y=0).
These bags are then individually wrapped in a paper envelope by folding them along the long sides. The PT-y.25 type is very popular because it protects the product hygienically at a reasonable cost. The tea bag with a crimped paper envelope is considered particularly environmentally friendly. As an option, the machine can be equipped to switch from an enveloped to a naked bag (for manual packing).
Bag size options: A | B
The following tea bag sizes are available:
A : Larger bag size 64 x 44 mm.
Thanks to its larger volume, this is the best choice for packing herbal and fruit teas.
B : Smaller bag size 60 x 40 mm.
This is the standard size for packing black tea.
The machines cannot be converted to other bag sizes.
Packing options: PT-y.25. 0 | 1 | 2
The following packing options are available:
PT-y.25.0 : Manual packing machine (hand packing).
Where high flexibility is required, or in countries with lower labour costs, these manual packing versions are very popular. These models are equipped with an automatic counter that counts the bags, stacks them and conveys them to an output channel. The stacked and pre-counted bags can then be taken out by hand and filled into pre-formed cartons or tins.
PT-y.25.1 : Single-row cartoning unit.
Pre-glued band boxes, adjustable between 15 and 30 bags.
Machines with automatic single-row cartoning are used by companies with a high degree of automation and with dedicated production lines for a specific box format.
PT-y.25.2 : Multi-row cartoning machine.
Flat carton blanks for up to 100 tea bags. This more complex cartoning is used in the rarer cases of large packs.
