Abstract
(EN)
A packaging material used in this bag for transportation of a silicon material is a laminate of a first resin base layer, a barrier layer, a second resin base layer, a resin layer, and a sealant layer, which are put on top of each other in this order, wherein the indentation elastic modulus (MPa) of the resin layer is lower than the indentation elastic modulus (MPa) of each of the first and second resin base layers by one or more orders of magnitude, the indentation elastic modulus (MPa) of the sealant layer is lower than the indentation elastic modulus (MPa) of the first resin base layer and the indentation elastic modulus (MPa) of the second resin base layer by one or more orders of magnitude, and the difference between the indentation elastic modulus (MPa) of the first resin base layer and the indentation elastic modulus (MPa) of the second resin base layer is less than the difference between the indentation elastic modulus (MPa) of the second resin base layer and the indentation elastic modulus (MPa) of the resin layer.

L'invention concerne un matériau d'emballage, utilisé dans un sac selon l'invention servant au transport d'un matériau à base de silicium, qui est un stratifié constitué d'une première couche de base en résine, d'une couche barrière, d'une deuxième couche de base en résine, d'une couche de résine et d'une couche de produit d'étanchéité, qui sont placées les unes sur les autres dans cet ordre. Le module d'élasticité d'indentation (MPa) de la couche de résine est inférieur d'un ou plusieurs ordres de grandeur au module d'élasticité d'indentation (MPa) de chacune des première et deuxième couches de base en résine. Le module d'élasticité d'indentation (MPa) de la couche de produit d'étanchéité est inférieur d'un ou plusieurs ordres de grandeur au module d'élasticité d'indentation (MPa) de la première couche de base en résine et au module d'élasticité d'indentation (MPa) de la deuxième couche de base en résine, et la différence entre le module d'élasticité d'indentation (MPa) de la première couche de base en résine et du module d'élasticité d'indentation (MPa) de la deuxième couche de base de résine est inférieure à la différence entre le module d'élasticité d'indentation (MPa) de la deuxième couche de base en résine et le module d'élasticité d'indentation (MPa) de la couche de résine.
