Pakasnax Multipack Wrapping Machine
The Pakasnax multipack wrapping machine is a horizontal form fill and seal machine, which has been specifically designed for multi-packing products such as bags of Crisps, Popcorn, Snacks etc.Packing these products in the multipack wrapping format presents several challenges, the main ones being retaining the collation during the wrapping process, and keeping the cut-off of the wrapping material to an absolute minimum.
Thanks to the multipack wrapping machine design these objectives are achieved, and savings are therefore made by using less wrapping material, and as a result of minimal downtime and by the elimination of waste.
The specific advantages are as follows;
The film folding box has been designed specifically to control the collation of primary products during the transfer from the infeed into the longitudinal sealing area.
The efficient sealing of the pack's longitudinal seam is achieved by the use of sufficient heat sealing rollers to correctly transfer the heat to the wrapping material without stretching it. For this reason the machine is equipped with a first pair of unheated driving rollers, plus two further heated pairs of rollers.
Radial adjustments can be made to the first pair of film rollers, thereby ensuring that the finished pack is always tight.
The standard multipack wrapping machine is fitted with a no-pack-no-paper sensor. Sensors are also fitted to detect if the collation of products is out of position. This ensures that the end crimp jaws do not destroy the primary bags. If the sensor is activated it will instruct the end crimp jaws to remain in the open position until a correctly positioned collation has been established. Those packs with the collation out of position will pass through the end crimp without being sealed or cut off, and will be rejected by the subsequent check weigher. These rejected bags can then be successfully re-cycled.
The end crimp unit is extremely robust, boasting 60mm diameter shafts on 250mm centres. In addition to this, the film holders can take reels of up to 800mm in width, which allows extremely large packs to be wrapped. The end crimp movement can be adjusted via the operator touch screen, ensuring that the sealing and cut-off is reduced to a minimum.
Automatic reel splicing is offered as an option and can give substantial savings in time as well as wrapping material. This feature is particularly beneficial when automatic feeding is used.
A pack-tamping unit is also offered as an optional extra. This unit is fitted on the infeed immediately prior to the folding box. This unit ensures that the collation is gently 'tamped' from the top to ensure a smooth passage through the folding box. This unit is also beneficial when an automatic feeder is fitted.
Another option is a hole punch unit, which can punch either a complete hole or a partial hole (butterfly). This allows the exhaustion of air from the multipack prior to case packing.
Feeding systems incorporating robotic loading can be supplied to make the loading and packaging process completely automatic.
