Whether metallized or demetallized films, natural matt textures produced with film-&-paper composites, or special-grade printing inks such as Supersilver or Iriodin – there is a growing demand for unusual effects. Using special manufacturing, printing and finishing processes, Wipak has extended its range of options.

Demetallized Films

Demetallization is a process where a metallized film is first of all printed before predetermined areas of the metal layer are washed off by alkali treatment. During the next stage, the printed side of the film is laminated with a transparent film to protect the graphics. A barrier layer ensures, for instance, that oxygen is kept out and the flavour is retained.

Supersilver

Innovative printing inks enable transparent films to obtain a remarkably genuine-looking silver finish. This unique effect is the result of a process developed by Wipak where a sparkling silver ink is applied by a special technique. The films provide transparency where required, plus an effective barrier for safeguarding perishable food products.

Silver Backing

This special-grade printing ink enhances the opacity of other printing inks and therefore ensures a consistently high print quality. As the silver flakes in the ink are extremely small and insulated, they are not detected by metal detectors during processing. The barrier provided by the film is located in the sealing layer, allowing the functions and properties to be fully maintained and even improved.

Iriodin

Packaging films finished with an Iriodin coating are an eye-catching option. The unusual mother-of-pearl effect is achieved by adding special pigments to the ink to produce the Iriodin coating, resulting in brilliant colours and high opacity. The coating is applied inline during the gravure printing process either over the entire surface or as a spot coating. Wipak applies a large number of Iriodin pigments, selecting them accordingly to suit the end use and to obtain the desired effect.

Matt Effects

Films resembling paper are a new pack design option. Using a special printing process, Wipak can produce prints which make the film look like genuine paper. The spectrum of effects that can be selected to suit the respective design ranges from the characteristic crumpled appearance to a fibre texture, plus striking visual effects such as matt or silky surfaces.
