Patent

CA 2506979

Thin, flexible plastic films, of the type used for the packaging of foodstuffs, may be printed using a laser marking technique by printing a layer or layers comprising a laser sensitive material and an ink so that heating of the laser sensitive material by absorption of laser radiation burns the ink selectively, so causing markings to appear. A further process for marking a flexible plastic material using a laser is disclosed, whereby to a surface of a substrate comprising said flexible plastic material a laser sensitive material which is or is associated with a material that generates gas on heating is applied, this is coated with a gas impermeable layer, then exposed to laser radiation such that raised markings appear on the exposed portions.

Des films plastiques minces souples, du type utilisé pour le conditionnement de produits alimentaires, peuvent être imprimés à l'aide d'une technique de marquage au laser et d'une encre, l'impression étant produite sur une ou plusieurs couches comprenant une matière sensible au laser, de sorte que le chauffage de ladite matière par absorption du rayonnement laser brûle sélectivement l'encre et produit des marques.
