Abstract
(EN)
The present invention provides: a multilayer structure that exhibits excellent separation strength between a base material and a gas barrier layer and excellent gas barrier performance after a retort process and that can maintain good external appearance without occurrence of interlayer separation after the retort process even in the presence of stress; and a packaging material and a product using said multilayer structure. The present invention pertains to a multilayer structure including: a base material (X); a layer (Z) that is laminated on the base material (X); and a layer (Y) that is laminated on the layer (Z). The layer (Y) contains a reaction product (D) between an inorganic phosphorus compound (BI) and a metal oxide (A) containing aluminum. The layer (Z) contains a polyvinyl alcohol-based resin (C) and a polyester-based resin (L).

La présente invention concerne : une structure multicouche qui présente une excellente résistance à la séparation entre un matériau de base et une couche barrière aux gaz et une excellente performance de barrière aux gaz après une stérilisation en autoclave et qui peut conserver un bon aspect extérieur sans risque de séparation intercouche suite à la stérilisation en autoclave même en présence de contrainte ; ainsi qu’un matériau d'emballage et un produit mettant en œuvre ladite structure multicouche. La présente invention concerne une structure multicouche comprenant : un matériau de base (X) ; une couche (Z) qui est stratifiée sur le matériau de base (X) ; et une couche (Y) qui est stratifiée sur la couche (Z). La couche (Y) contient un produit de réaction (D) entre un composé de phosphore inorganique (BI) et un oxyde métallique (A) contenant de l'aluminium. La couche (Z) contient une résine à base d'alcool polyvinylique (C) et une résine à base de polyester (L).
