Abstract: A two-ply laminate is provided for production of flexible containers such as stand-up or gusseted pouches for 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 maybe 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.

Abstract: A bag includes first and second polyolefin walls with a thickness of between 3 and 12 mils. The bag has joined opposing side edges, opposing end edges, and at least one seal line proximate one of the end edges. The seal line extends laterally from one side edge to the other for sealing closed an end of the bag. The improvement in the bag is a perforated tear line defining an easy-open corner portion of the bag removable to form a pourer. The perforated tear line includes a vertical segment defined by a series of closely spaced perforations formed in the first and second walls of the bag and closer to one side edge of the bag than the other. The vertical segment extends in a straight path outwardly from the seal line and generally parallel to the closer side edge of the bag. An arcuate transition segment of perforations begins at an end of the vertical segment and extends in an arcuate path towards the closer side edge of the bag.
