Abstract
(EN)
The purpose of the present invention is to provide a paper barrier material that has excellent barrier properties and reduced environment load. As the solution, provided is a paper barrier material which comprises a paper base material and at least one barrier coat layer disposed thereon, and which is characterized by satisfying any one or more of the following conditions (1) to (3). (1) The barrier coat layer contains a pigment, and the barrier coat layer contains 50 wt% or more of at least two types of flat inorganic pigments A and B with respect to the entire pigment in the barrier coat layer. (2) The barrier coat layer is a water vapor barrier coat layer, the water vapor barrier coat layer contains a water vapor barrier-property resin, and the paper base material has a drip oil absorbency of 50 seconds or more. (3) The barrier coat layer is a water vapor barrier coat layer, and the water vapor barrier coat layer contains at least a water vapor barrier-property resin A having a melting point of 110°C or higher and a water vapor barrier-property resin B having a melting point of lower than 110°C.

La présente invention concerne un matériau barrière en papier qui présente d'excellentes propriétés de barrière et une charge environnementale réduite. La solution selon l'invention porte sur un matériau barrière en papier qui comprend un matériau de base en papier et au moins une couche de revêtement barrière disposée sur ce dernier, et qui est caractérisé en ce qu'il satisfait à une ou plusieurs des conditions (1) à (3) suivantes. 1) La couche de revêtement barrière contient un pigment, et la couche de revêtement barrière contient 50 % en poids au minimum d'au moins deux types de pigments inorganiques plats A et B par rapport à l'ensemble du pigment dans la couche de revêtement barrière. (2) La couche de revêtement barrière est une couche de revêtement barrière contre la vapeur d'eau, la couche de revêtement barrière contre la vapeur d'eau contient une résine à propriété de barrière contre la vapeur d'eau, et le matériau de base en papier a une capacité d'absorption de condensat supérieure ou égale à 50 secondes. (3) La couche de revêtement barrière est une couche de revêtement barrière contre la vapeur d'eau, et la couche de revêtement barrière contre la vapeur d'eau contient au moins une résine A à propriété de barrière contre la vapeur d'eau ayant un point de fusion supérieur ou égal à 110 °C, et une résine B à propriété de barrière contre la vapeur d'eau ayant un point de fusion inférieur à 110° C.
