Optionally, the first and/or second outer film members may be narrower, coextensive, or extend beyond one or both of the first and second tube edges of the lay-flat tube member. In a bag embodiment a lateral seal is provided through the first and second tube walls and the first and second outer film members and extends laterally across the width of at least the lay-flat tube member.
