Abstract
A bag structure includes, in an example embodiment, a bag body including side walls having inner and outer surfaces, and the bag body further includes a top end and a bottom end. A closure member is coupled to the top end for opening and closing the bag body. A sealing material is applied to an area proximate at least one of a top edge of the side walls and a bottom edge of a portion of the closure member. An adhesive member is secured to the bag body. The adhesive member includes a reinforced section and an adhesive section. The adhesive member is configured to retain the top end of the bag body in a folded over relationship until the adhesive member is severed along the reinforced section.
