Abstract
Provided is a packaging bag which can prevent the entry of water between a handle and a body, as well as can maintain proper degrees of easy-opening properties and bag-break strength. A packaging bag includes an easy-peel seal. The seal includes first regions in which multiple belt-shaped seals are spaced from each other in the width direction and second regions in which a single belt-shaped seal is disposed. The first regions and second regions are alternately disposed adjacent to each other in the length direction of the belt-shaped seals. The single belt-shaped seal in each second region has a wide width so that the multiple belt-shaped seals in the adjacent first regions can be connected to the single belt-shaped seal.
