Basic Description

The PT-6 type machines produce rectangular single-chamber tea bags (without thread and tag) by sealing the seams on 4 sides with heat-sealable filter materials.

There are two versions:

PT-6.2: Produces tea bags in 2 lanes.
PT-6.4: Produces tea bags in 4 lanes.

The high-speed PT-6.4 machine is our flagship model, which can produce up to 1,000 tea bags per minute. The smaller version is the PT-6.2, which produces up to 500 tea bags per minute. In either case, a pair of 2 bags is held together by thin nose pieces so that they stay together and can be handled more precisely, but are very easily torn apart by the consumer.

Since the machines use two separate rolls of filter material, they can produce tea bags with two different materials on each side, e.g., filter paper on the bottom and a more transparent non-woven fabric or a completely transparent PE mesh on the top, resulting in a unique visual effect: through the mesh, one can see, smell, feel, and enjoy the tea with all senses against the background of the opaque white filter paper.

The machine is exceptionally reliable and effective.

Bag Size Options: S | L

The following tea bag sizes are possible:

S: Standard bag size 65 x 61 mm.
L: Larger bag size 65 x 71.5 mm.

The machines are not interchangeable between bag sizes.

Packaging Options

For the final packaging, there is a manual and an automatic option:

In the manual version, the tea bags are stacked onto a conveyor belt to fill pre-made cartons, or they are hand-packed.
In the fully automatic version (with cartoning), the tea bags are stacked fully automatically into a cardboard box. Due to the carefully coordinated movements of the top loaders, the bags are placed very neatly into the box.

In our optional high-end version, a KA-20 carton erector prepares the cartons from flat blanks using a hot glue system and feeds these open cartons to the machine. After filling, the boxes are weighed and forwarded to a lid closer. Finally, the box can be glued to make it shelf-ready without cellophaning. Additionally, an inkjet system can mark the boxes with a best-before date and batch number.

Frequently Asked Questions

How many tea bags does the PT-6 produce per minute?

The PT-6.4 produces up to 1,000 tea bags per minute in 4 lanes, the PT-6.2 up to 500 in 2 lanes.

Which tea bags does the PT-6 produce?

Rectangular single-chamber tea bags without string and tag, sealed on four sides with heat-sealable filter material. Two bags at a time stay connected by thin webs and are easy to separate.

Can two different filter materials be combined?

Yes. The machine works with two separate material reels, for example filter paper at the bottom and a transparent PE mesh on top. This keeps the tea visible through the mesh.

Which bag sizes are possible?

Format S measures 65 x 61 mm, format L 65 x 71.5 mm. A machine cannot be converted between the sizes.

How are the bags packed?

Manually via a conveyor belt, or fully automatically by cartoning with a top loader. Optionally, a KA-20 carton erector prepares the boxes, followed by weighing, lid closing, gluing and inkjet marking.
