The effective HST PT-33 machinery manufactures non-heatsealable double chamber filter bags with an outer airtight foil envelope. It is based upon our approved basic platform machine PT-21 and can produce 150 up to 160 bags per minute. The bag comes with string and hard tag, optionally with knotting technology (on both sides or by request only at the bag side), otherwise with standard food grade aluminium staples. These bags are then individually packed into an outer foil envelope by edgesealing seams at 3 sides, with a wide material range from oriented polypropylene (OPP), cellophane, PLA, paper compounds (with aluminium or PE and the like).
The foil reel transport can optionally be equipped with a thermotransfer printer to mark the foil f.e. with a best-before-date and lot-number or even labeling it with a product identification.
The version PTx33 can optionally be equipped to be convertible from enveloped to naked bag.
The PT-33 has multiple advantages: The tea bag is protected completely aroma tight in both directions. The envelopes are fully wrinkle-free, because of the horizontal position of the tea bag during the heatsealing process. The environmental resource consumption can be optimized because the PT-33 is able to run even foils down to 35 ?m thickness. The machine is therefore not only reliable, but also quite economic for producing at reasonable costs.
The following packing options are available:
• Manual handpack machine (models PT33, PT133, PT233)
• Single row cartoning device for pre-glued belt boxes between 15 and 30 bags (models PT33.1, PT133.1, PT233.1)
• Multirow cartoning device for flat blank cartons up to 100 tea bags (models PT33.2, PT133.2, PT233.2)
