Abstract: The present invention relates to a flexible container (10). In an embodiment, the flexible container includes a first flexible film (12) superimposed on an opposing second flexible film (14). The first flexible film and the second flexible film are sealed along a common peripheral edge (16) to form an inner container having a closed chamber. The first flexible film and the second flexible film each has an outermost layer comprising an ethylene-based polymer. Each outermost layer is a surface-treated layer having a surface energy from 33 mN/m to 36 mN/m. The flexible container includes a peel sleeve (22, 24) superimposed on each respective outermost layer and along the common peripheral edge. The flexible container includes a release material (26) located between the peel sleeve and each outermost layer along the common peripheral edge. The release material releasably attaches the peel sleeve to the inner container.
