摘要： An easily openable sealed package bag (P) which hermetically seals a material to be packed (W), such as liquid, powder and viscous material, by longitudinally and laterally sealing three or four sides of a package film (F). A seal opening notch (N) comprising a cut is formed in a sealed portion (S) of the package bag (P) in such a way as to extend in a direction of depth of the sealed portion (S). The sealed portion (S) is also formed with a bent portion (B) adjacent to the seal opening notch (N). The easily openable sealed package bag is capable of enhancing the ease with which the package bag can be opened and the ease with which a seal opening portion can be identified by sight or by touch, without producing cut chips of the package bag. An apparatus for manufacturing such easily openable sealed package bags is also provided.
