Packaging machine GBK 420

The machines are designed according to protection class IP54. Wet cleaning of the machines inside the cutting and packaging room is not recommended as moisture and bread crumbs directly cause the formation of mold spores.

Wet cleaning should therefore only take place outside the cutting and packaging room: components of the machine, such as guide plates, can be dismantled and cleaned at an external washing area. After drying and disinfection, the hygienically flawless dry components can be inserted into the device and reused.

Change kits allow cleaning and preparation in addition to the production operation.

Packaging means: positioning products automatically in a bag, extracting residual air from the bag, closing the bag close to the product inside the packaging machine.

Closing means: The products are either introduced externally into the bag or manually inserted into the bag on the device.
Some devices suck the residual air out of the bag, after which the bag automatically closes inside the device.

In the case of the GBK type, standing disks are packed, while the VS type packs lying disks. Both systems are able to package other types of products and products grouped differently.

GBK type

- Standing discs
- Whole breads
- Grouped products fast food

VS type

- lying discs
- Stacked flat breads (tortilla, arabic bread, pitta)
- Grouped products

Bag sizes depend on the products and the orientation of the products in the bag.

In any case, the product tolerances must be considered. This is especially important when several products are packed side by side, one after the other or one above the other in a single package. A beautiful packaging fits as closely as possible to the product and supports the product. The sizes recommended by GHD Hartmann can be looked up in an Excel spreadsheet.

The noise emission initially depends on the type of machine. Packaging machines, cutters or systems for grouping are fundamentally different due to the different functions.

Another factor is the nature of the products, which can behave differently during processing and transportation. A machine may be very quiet at idle, but produces varying amounts of noise during processing, depending on the products.

The type of cover also has a great influence on the noise emission: Polycarbonate viewing covers significantly reduce the noise level, while perforated grids can not significantly reduce noise emissions.

As a rule, the maximum noise emission of the machines is not more than 78 dB (A).

By "quality closure" is meant the single or double row perforation sealing of the bag ruffle. The bag can not be opened without breaking the seal.

Customers can thus control possible manipulations of the packaging or the products on the shop shelf.

The quality seal is not a hermetic seal.

In addition to contactor controls for simple devices, GHD Hartmann Maschinenbau offers systems from the manufacturer Omron as a standard controller for more complex tasks.

Siemens or Allen Bradley are available as options.

According to ISO 8573-1 with reference to VDMA standard sheet 15390-2, we specify a compressed air quality that we recommend when using the machines and devices.

The type of bag closure depends on the machine type. Some devices are designed exclusively for one type of closure, others can be delivered with different closure systems. A machine can only be executed with a kind 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.

Hart-Lock / Kwik-Lok®: Widely used in North America and Asia. No metal component in the closure, but difficult 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 / Welding: The sealing of bags with a sealing system is available for different machine types. Here is to pay attention to the nature of the packaging material and its welding properties. For pillow packs, the sealing of packaging films takes place on the longitudinal and transverse sides. Depending on the machine type, the film projections are cut off during sealing.

Quality closure: In addition to the clip closure or Kwik-Lok ®, a quality closure can optionally be introduced within the GHD Hartmann packaging machine. This closure is either one or two rows and switchable. It increases the security against external manipulation in sales.

Twist - Closure: Widely used in South America and the English-speaking world. GHD Hartmann can not offer an integration within the packaging machines. This closure is placed after packing the products in the bag with a separate device. The removal of air from the bags when closing is technically not possible here.

GHD Hartmann supplies HPD printers with between 6 and a maximum of 13 positions for printing on the clip band. For Hart-Lok or Kwik-Lok (R), a 6-digit HPD printer from Hartmann can be offered.
