A four corner bag constructed of flexible thermoplastic sheet or film material having overlying front and rear wall panels and a bottom sealed end. The upper portion of the bag includes a first closure region terminating in a top sealed end, a second closure region disposed inwardly of the top sealed end, and a perforated seal or tear strip extending across the width of the bag and located between the first and second closure regions. The second closure region includes an inner heat seal which extends approximately halfway across the width of the bag and a reclosable fastener which extends the remaining distance across the bag. In one embodiment, the inner heat seal is oriented transversely across the bag while the reclosable fastener is upwardly angled so that it forms a natural pour spout during use. In other embodiments, the reclosable fastener is transversely oriented while the inner heat seal is angled. In still other embodiments, the reclosable fastener is vertically or longitudinally oriented and disposed adjacent a side edge at an upper corner region of the bag. In all embodiments containing a reclosable fastener, the tear strip is removed to access the reclosable fastener.
