Abstract
A container (10) suitable for medical uses comprising a first planar member (18), a second planar member (22), a first seam (24) and a second seam (26). The first planar member (18) is of a multi-layered polymeric material and further comprises a first substrate (38) and a first layer (46). The first layer (46) is disposed on a portion of the first substrate (38) to separately define a first overlap area (58) and an adjacent first peripheral flange (62). The second planar member (22) is of a multi-layered polymeric material. The first seam (24) attaches a portion of the first overlap area (58) to the second planar member (22). The second seam (26) is spaced from the first seam (24) and attaches a portion of the first peripheral flange (62) to the second planar member (22).
