Container wall post-forming |
摘要 |
Tube containers that have a barrier structure can be altered in shape by post-forming techniques. This post-forming comprises placing a formed and heated tube on a mandrel and having a surrounding mold having the final desired shape of the tube. The inner wall then is pressurized through the mandrel with an optional use of a vacuum on the mold. The tube walls are altered in shape to a degree that will not be deleterious to the barrier properties of the tube wall.
