It includes: (1) a flexible assembly material table to form a semi closed container with a hole defined by the edge. The package has an address filled perpendicular to the above holes; and (2) a closed area and edge, including a first area and a second area deformed at the molecular level, which will undergo geometric deformation when the blade of the package is affected by the traction. Includes multiple cam elementsAs ribs, each is oriented East by a larger axis and a smaller orthogonal. In addition, this closed area can be extended to address filling to respond to the driving force of parallel application with address filling.This is separated from the surrounding area, adjacent to the surrounding area, without induced expansion, with a width of 0.1 to 100 mm, parallel to the filling direction
