Abstract: The present invention provides a multilayer structure that has excellent gas barrier properties and an excellent peel strength between a base and a gas barrier layer after retorting, and that can retain a good appearance with no delamination even after retorting under stress. The present invention also provides packaging materials and products including such a multilayer structure. The present invention relates to a multilayer structure comprising a base (X), a layer (Z) stacked on the base (X), and a layer (Y) stacked on the layer (Z), the layer (Y) containing a reaction product (D) of an aluminum-containing metal oxide (A) and an inorganic phosphorus compound (BI), the layer (Z) containing a polyvinyl alcohol resin (C) and a polyester resin (L).
