A packaging bag which allows the user to easily extract the contents thereof by a predetermined amount. In a packaging bag with a fastener, or the like, a packaging bag (1) is formed by connecting an extracting unit (3) composed of a separate body to a bag main body (2). The extracting unit (3) is constituted of wall surface sections (11) opposed to each other, and a fastener (13) arranged on the inner surfaces of the wall surface sections (11), and furthermore, the unit is integrally molded by injection molding. In the extracting unit (3), having the fastener (13) as a boundary, an edge section on one side serves as a connecting opening section (15) for connection with the bag main body (2), and an edge section on the other side serves as a closure section (16) constituted as an edge of the packaging bag. Between the closure section (16) and the fastener (13) on the wall surface sections (11), an opening section (20) which is to be cut up to separate the extracting unit (3) is provided. ® KIPO & WIPO 2007 |
