Abstract: A multilayer film for flexible packaging, comprising at least a base layer (B) based on polypropylene, having a first side and a second side; a first coating layer (A) associated with the first side of said base layer (B); a second coating layer (C) associated with the second side of said base layer (B); wherein a silicone polymer with very high viscosity utilized as lubricant agent is added to at least one of said first and second coating layers (A, C).

Abstract: To increase the barrier effect of a metallized film intended for use I the packaging, in particular of food products, a particular composition of the plastic layer (A) is suggested, on which the metal layer (M) is deposited by vacuum evaporation. The plastic layer comprises a polypropylene and butene copolymer and is subjected to a preliminary surface activation treatment, preferably to a flame treatment, and to a subsequent plasma treatment under partial vacuum conditions prior to metallization.

Abstract: The method of varnishing a printed medium is characterized in that: a laminated material 9 consisting of two connected layers is used for the production of the template F; the upper layer 11 of the material is cut along the pattern of the template which is to be formed, while the lower layer 13 is kept whole; the areas of the upper layer corresponding to the areas not to be varnished are detached from the lower layer; and the laminated material is applied to a press device 5 capable of interacting with an opposing cylinder 7, the upper layer of the laminated material collecting the varnish from a distribution device 1,3 and applying the varnish to the medium to be varnished.
