Title (EN) POLYMERIC FILM INCLUDING MICROSPHERES
(FR) FILM POLYMERE COMPRENANT DES MICROSPHERES
Abstract: front page image
(EN)A thermoplastic packaging film includes a carrier layer containing up to about 1.0 weight percent of spherical alkali aluminosilicate ceramic particles having a refractive index of about 1.52. The carrier layer preferably is a heat sealable layer which includes a polymer having mer units derived from ethylene. The refractive index of the overall film, and particularly that of the carrier layer, preferably is in the range of about 1.50 to about 1.54.
(FR)L'invention porte sur un film d'emballage thermoplastique comprenant une couche support renfermant jusqu'à 1,0 % en poids de particules céramiques sphériques d'aluminosilicate de métaux alcalins dont l'indice de réfraction est d'environ 1,52. La couche porteuse est de préférence une couche thermoscellable qui comprend un polymère dont les unités mer sont dérivées de l'éthylène. L'indice de réfraction de l'ensemble du film, et notamment de celui de la couche porteuse, est de préférence compris entre environ 1,50 et environ 1,54.
