POUCH HAVING CONCAVELY-CURVED CORNERS

摘要

A pouch (100) has a sheet (120) containing at least one layer of a film material. The sheet forms a tube (142) that is closed with a seal (122) to form a volume (144). The seal (122) contains a first edge (128) and the sheet contains a second edge (130) in connected relation to the first edge (128). A curved seal (132) joins the first edge (128) with the second edge (130). A sealing jaw (150) and a method for forming such a pouch are also described.
