VTT Technical Research Centre of Finland has developed printable
holographic-like film technology for plastic-based and fibre-based packages,
enabling cost-effective and environmentally friendly dynamic printing. This
allows wrappings, mobile phones, CD jewel cases and laptops to be given an
attractive new look. The technology is suitable for mass production and can be
integrated into existing printing presses. Iscent Oy, a new Finnish
enterprise, is commercialising the technology jointly with VTT.
Applications of the technology include the ability to label genuine brand
products with a technical solution that is difficult to counterfeit. Printers
can reduce the use of inks with this method, and advertising agencies can
create striking packages that are environmentally friendly. Applications
further include transparent films and gift wrappings, which can be made more
decorative without compromising transparency. The technology is also suitable
for injection-moulded plastic products such as mobile phone shells, CD jewel
cases and laptops, and for laminate solutions such as interior design elements
and sports equipment.
Commercial holograms in the printing
industry are almost without exception printed on narrow-web lines. Iscent is
investing in the capacity to produce end product up to 1,200 mm wide, which
will open up a completely new range of business opportunities, enabling
large-volume product lines thanks to minimised raw material costs.
holographic technologies are based on metal foiling or coatings, laminated
structures and UV curable varnishes. With the new light scattering method,
none of these will be needed, nor will any other extra materials: the rainbow
colours are generated simply by altering the topography of the plastic or
paper surface being treated.
The new method is based on a hot
embossing technology where a pair of rollers similar to a calender exerts nip
pressure on the plastic or paper web run through them. The lattice design on
the main roller is copied to the web by the heat and pressure.
Oy, based in Tampere, Finland, is commercialising a new, high-quality optical
effect film material. Iscent supplies film materials to Finnish and foreign
companies and licenses its technology to converting industry of film
materials. The new method enables cost-effective production and has a
potential worldwide market. The technology can be licensed internationally for
a scalable business opportunity.
