IML labels can embed an oxygen barrier function. This is achieved by an intermediate EVOH layer or
an aluminium layer. Barriers to water vapour, light and aromas are also possible.
Several food products need to undergo pasteurization but this thermal treatment
stresses the label and its print. Viappiani has a good IML solution for pasteurized products.
So called “low distortion labels” follow some unevenness of injected parts
without creating unaesthetic wrinkles.
With an IML label printed on both sides you can inject clear polypropylene and read some text
(for example a recipe) on the inside of the lid. The usable surface of the label is doubled.
For traceability, sorting, or other purposes, ordinary codes such as QR-codes and Datamatrix codes
can be printed with a UV reacting ink in order to be readable by a suitable scanner but not visible to the human eye.
IML labels can also have a removable proof of purchase. This coupon is precut and can be
removed by the user for a collection of points or other marketing initiatives.
Different substrates and technologies allow us to offer superclear labels. Whenever transparency of the
container is the most important aspect, for example in case of medical products.
A special invisible print on the back of the label allows our customer to use a cheap inspection control
system to detect overinjections.
Thanks to a special technology you can smell the perfume of the contained product,
for example a lavender scented fabric softener, by simply rubbing the label surface.
Also plastic IML labels can show a premium metal look. A fully metalised label can even look
like a tincan container. With the latest technologies the metalised labels can also be charged statically.
A 500 microns thick label becomes a structural part of the lid. Only the black material
of the frame is injected. The part has clear and black material without using a dual-colour injection machine.
