A two-ply laminate is provided for production of flexible containers such as stand-up or gusseted pouches for snacks or beverages. The laminate is made from an outer web and an inner web. The outer web provides printability, stiffness and thermal resistance. The inner web is made of three layers. The outer layer may be metallized with aluminum to provide resistance to moisture migration. The middle layer provides barrier qualities for retardation of the migration of slipping agent on an inner or sealing layer. The inner layer provides a sealing quality and a low coefficient of friction to allow the laminate to slide over manufacturing machines.
