Printed multilayer polymeric films are provided that include a flexible polymeric film layer, one or more non-photochromic layers each including a solvent-based ink composition having one or more non-photochromic inks that are at least partially transparent to ultraviolet radiation, and one or more photochromic layers each including a water-based ink composition having one or more photochromic inks that undergo a color change upon exposure to ultraviolet radiation. Also provided are methods for making the printed multilayer polymeric films. Packages for containing a product therein that include the printed multilayer polymeric films are also provided. Methods for making the packages and methods for packaging a product that employ the printed multilayer polymeric films are also provided. Rolls of film for forming the packages that include the printed multilayer polymeric films are also provided. L'invention concerne des films polymères multicouches imprimés qui comprennent une couche de film polymère souple, une ou plusieurs couches non photochromiques comprenant chacune une composition d'encre à base de solvant ayant une ou plusieurs encres non photochromiques qui sont au moins partiellement transparentes au rayonnement ultraviolet, et une ou plusieurs couches photochromiques comprenant chacune une composition d'encre à base d'eau ayant une ou plusieurs encres photochromiques qui subissent un changement de couleur lors d'une exposition à un rayonnement ultraviolet. L'invention concerne également des procédés permettant de fabriquer les films polymères multicouches imprimés. Des emballages pour contenir un produit en leur sein qui comprennent les films polymères multicouches imprimés sont également décrits. Des procédés permettant de fabriquer ces emballages et des procédés d'emballage d'un produit qui utilisent les films polymères multicouches imprimés sont également décrits. Des rouleaux de film pour former les emballages qui comprennent les films polymères multicouches imprimés sont également décrits.
