Food

Most of the packaging material commonly used in the food industry bear the unpleasant property ti become charged in fabrication or processing (refer to material in Your Problem). Apart from disturbing unruly adhesion, dust and dirt are attracted, leaving the fulfillment of cleanliness standards difficult – an active neutralisation can help solve the issues. In the following processes IONTIS products are already used by clients for neutralisation, but sometimes also for systematic charging (adhesive effect):

(Tubular) Bag Packing

Especially in the form-filling-sealing process, unwinding the film is causing a static charge to build up, requiring an immediate static neutralisation to prevent the goods to be filled from adhering to the film and render the seals leaky after welding.

Die Casting

Moulded Parts can become charged during the cooling process and stick to the form, thermoset material can also produce flash/flakes which remains sticked to the form: the form parts are via ionising nozzles neutralised and blown free.

At the outfeed belt and/or conveyor belts charged parts can adhere and lead to blockages and need to be neutralised with ionisers.

InMould Labeling

The label to be applied is charged with a charging ioniser, to place it correctly in the form and ensure precise fixation with no slipping in the forming process.

Deep-drawing

Caused by deformation and cooling, in the thermoforming process electrostatic charge is generated which must be eliminated with anti-static ionisers to prevent stacking problems and dust attraction.

In inline systems, both sides of the film are discharged/neutralised before forming or closing, so the seal will not contain impurities.

Cup & Bottle Filling

Prior to filling, vials, ampoules and bottles are ionised with point-precise neutralising ant-static devices, to eliminate statically caused adhesive forces and keep the containers clean. Thus it is also possible to homogenously fill even several different layers into the container.

Powder Filling

The used plastic container (but beware: glass also!) can get charged in the carousel system and consequently attract dust, leave powder adhered on the outer surfaces and remain stuck to the fill head – static neutralisation of the containers and/or at the filling funnel will solve the problem.

RFID Labels

High-performance anti-static ioniser ensure during un-/rewinding, die-cutting as well as placing of the RFID tags, that the charge generated through carrier film and the tag material does not damage the fragile chips.

Product Coding

During inkjet coding static charge on the web can make the applied ink generate contortions in the print pattern but also impact the electronic parts of the printing head, if no static neutralisation is performed prior to printing.

Labeling

In the bottle labeling process, the label rolls can get charged and need be statically neutralised, in order to guarantee the proper feed and placement of the labels especially at high speeds.

The tubular film can get a charge from friction and cutting in sleeve labeling. Applying a proper static neutralisation can ensure the film will not cling to the mandril and fall correctly over the bottle/container after the cut.

Pinning Food Sachets

Applying a generated charge will ensure also at high web/conveyor speeds, that the food sachets are fixated using an adhesive effect and, cards, recipes and additional supplements can be fixed precisely at insert stations.

Over-Wrapping

During unwinding and forming of the shrink film to a tubular film later can get a static charge and needs be neutralised for further efficient processing.

A systematic charging of the overlapping foil sides just before the shrink tunnel can prevent a rupture of the film.

Wrap-around Packaging During the unwinding of the film and at the winding bars, an anti-static bar can warrant a trouble-free wrapping of the foil around the goods.
