Abstract

Ce film multicouche possède d'exceptionnelles propriétées de barrière contre le N¿2?, l'O¿2? et le CO¿2? sans contenir de feuilles de métal. Ce film peut également être pourvu de propriétés haute barrière contre l'humidité ainsi que d'une forte opacité à la lumière, et il peut également être rendu très résistant aux manipulations abusives, ce qui le rend particulièrement approprié pour l'emballage de bobines relativement lourdes de film photographique non dévelopé. Un film multicouche opaque préféré est particulièrement approprié pour l'emballage de produits sensibles à la lumière, tels que des films photographiques et des papiers photographiques, et il possède une couche scellante extérieure et au moins une couche intérieure contenant du noir de carbone, de préférence deux couches intérieures contenant du noir de carbone. La ou les couches intérieures du film qui entourent le noir de carbone empêchent le film de frotter contre le noir de carbone sur l'équipement d'emballage et de fabrication du film, ainsi que le produit emballé dans le film. Des articles tels que sacs, étuis et sachets peuvent être fabriqués à partir de ce film.
