Sealed bag with unsealing tape

Abstract

A zipper 3 (translator's comment: the zipper should be coded as 11 instead of 3 ) is stuck on the opening part 2 side of a packaging bag 1 and a heat-sealed part 12 is formed in the outer side from the zipper 3 (translator's comment: the zipper should be coded as 11 instead of 3 ) to seal the packaging bag 1 . A band-shaped unsealing tape 3 is stuck, in parallel to the opening part 2 , on one inner surface of the packaging bag 1 in an area between the zipper 3 (translator's comment: the zipper should be coded as 11 instead of 3 ) and the heat-sealed part 12 . A cutout part 4 is formed on a surface opposite to the surface with the unsealing tape 3 stuck thereon at the end part of the unsealing tape 3 . A pair of cut-in parts 5 are formed on the packaging bag 1 at the end part of the unsealing tape 3.
