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. A diagonal segment of perforations extends along a straight incline from an end of the arcuate transition segment towards the closer side edge of the bag. The vertical segment, arcuate transition segment, and diagonal segment cooperate to enable the corner portion of the bag to be torn in a progressive tearing motion to form a hole in the bag from which the contents can be poured.
