Hartmann closing devices and Hartmann packaging machines have an integrated aggregate for the closure application. Depending on the machine type and series, the closing system can be supplied for the application of a certain type of bag closure. Later conversions are partly possible.
Clip closure: The closure used very often in Europe. Cost effective with the possibility of printing on the closure. Good to use for PE bags, PP bags and paper bags.
Kwik-Lok ®; Schutte Clipps ® G or corresponding closures: Widespread in North America and Asia. No metal components in the closure, but difficult to detect or undetectable. Unsuitable for paper bags. A printing of the closure is possible.
Tape - Closure: In the United Kingdom, in English-speaking countries and occasionally in Africa, the tape closure is applied. Hartmann offers this type of closure in packaging machines and specially designed sealing devices. A printing of the tape closure is possible.
Sealing: The sealing of bags with a sealing system is available for various types of machines. For closing, the filled bags can be sealed, or the frill can be sealed in addition to the conventional closure. The packaging material and its welding properties must be observed.
In the case of pillow packs, the packaging film is sealed on the longitudinal and transverse side and, optionally, as a division in the longitudinal direction. Depending on the machine type, the protruding film is cut off during sealing.
Tamper proof / Quality closure: In addition to the clip closure or Kwik-Lok ® / Schutte Clipps ® G closure, a tamper proof application system can optionally be installed within the GHD Hartmann machine. This lock is either one or two rows and can be activated. It increases security against manipulation from outside during sales.
Warp Close: With the Wrap Close, paper but also plastic bags can be closed. The bag is automatically wrapped on the opening side and secured and closed with a label.
Twist - Closure: This closure is known in South America and in English-speaking countries. GHD Hartmann cannot offer integration within the packaging machines. This closure is attached with a separate device provided by the customer after the products have been packed in the bag. For technical reasons, it is not possible to remove air from the bags when they are closed.
