I believe the picture was posted as way to show the tubes were not fragile. As they still stated after the picture was posted the issue and the fix that was on its way. The point is clear that this is not celephane wrap, it has some rigidity to withstand pressure. The "PIG' was also an issue as it swelled, that was explained they reduced this attribute, but no matter what it will still swell. Seams can by seperated after many times of passing through, pressure is not the overall cause, it is just what finally breaks through. The stretching that occurs from ach pass on the otherhand stress the plastic and the weakest point is obviuosly the fused together seam.
