Abstract

Selon un mode de réalisation à titre d'exemple de l'invention, un film comprend une structure coextrudée ayant à la fois une couche de peau striée extrudée qui comprend une pluralité de stries, et une couche de noyau. Les stries sont espacées par une partie jointive qui est formée d'une seule pièce avec les stries. Le film comprend également un agent de coloration qui est sensiblement plus apparent dans les stries que dans la partie jointive, de telle sorte qu'un contraste de couleur et/ou d'intensité de couleur entre les stries et la partie jointive est visible.
