<p>A packaging film (10) consists of a first polymer film layer (12), a printed identification layer (24) covering at least one zone of the first polymer layer, a second polymer film layer (18), and at least one adhesive layer (26) between the identification layer and the second polymer film layer. The packaging film (10) consists of a first polymer film layer (12), a printed identification layer (24) covering at least one zone of the first polymer layer, a second polymer film layer (18), and at least one adhesive layer (26) between the identification layer and the second polymer film layer. The identification layer contains a layer of a polymer, preferably heat-sensitive, and at least partially stamped and/or metalized and applied by heliography and/or flexography. the adhesive layer is hotmelt and can contain wax, paraffin wax, thermofusible polymers and nonfusible mineral particles.</p> |
