The film and method of producing same of the present invention comprises a film capable of serving as self-adhering label stock and not requiring a secondary coating process or a release liner. The film comprises a smooth side, a rough side and, optionally, one or more core layers interposed between the smooth side and the rough side. A heat-activated adhering material comprised of certain polymers and co-polymers associated with the smooth side of the film prevent the need for traditional adhesive coating and/or release liner.
Le film produit grâce à ce procédé consiste en une pellicule à même de faire office de film d'étiquetage auto-adhésif n'exigeant pas d'enduisage secondaire ni l'ajout d'une feuille anti-adhésive. Ce film est constitué d'une face lisse, d'une face rugueuse et, éventuellement, d'une couche noyau, sinon de plusieurs, venant s'intercaler entre les faces. Une substance adhésive thermocollante faite de certains polymères et copolymères, associée à la face lisse de ce film, évite d'avoir à recourir à un enduit adhésif classique et/ou à une feuille anti-adhésive.
