Abstract: The invention is a packaging system having a plurality of flexible packages that are arranged in a stack and held together with a clip having a pair of fingers and a retaining tongue that support and hold the flexible packages in the stack. The clip permits an outermost package to be filled and then removed from the stack with minimal tearing or damage to the flexible package. The clip comprises a body formed of a resilient flexible material, a pair of fingers extending outwardly in opposite directions from the body, and a resiliently deformable retaining tongue formed in the body that is configured and arranged to apply a clamping force against the stack so that the packages are retained in a stack. The clip and the fingers may comprise a flexible material that can collapse so that the flexible bag may be easily removed from the stack.
