PURPOSE: To provide a packaging bag excellent in gas barrier properties, having no humidity dependence of the gas barrier properties, also excellent in transparency, resistances to heat and impact, and, moreover, having an advantage over production cost. CONSTITUTION: A laminated material is formed from barrier films alone, or from a barrier film laminated onto othr layers, wherein a barrier layer comprising an amorphous SiOx obtained by burning polysilazane in ambient air is laminated onto at least one of faces of a base material. The laminated material thus made is shaped into a desired form to make a packaging bag. |
