Abstract
A non-durable flexible container can include a first film wall including a first portion comprising at least one first structural support member defined in the first film wall, and a second portion that is free of a structural support member. The container can further include a second film wall including at least one second structural support member defined in the second film wall, wherein at least a portion of the first structural support member is adjacent to at least a portion of the second structural support member to define a seam region, and a side of the seam region defines an edge of the non-durable flexible container. The container can also include a closed produce volume defined between first and second film walls; and a seam projecting outwardly from the seam region at an intersection of the first and second film walls.
