<p>The invention relates to an elastic, substantially non-stretched film produced from olefinic materials that is completely free of PVC and that is yet adapted to the requirements of a film, such as a film for medical purposes, for example for heat sterilization. The inventive film has elastic properties up to a certain point that depend on the film's thickness, that means no permanent deformation can be observed. When the tensile stress is further increased, the film is deformed, that is it shows a plastic behavior until it finally tears or breaks. The transition is fluid since, unlike conventional films, the inventive film has no negative increase in the yield point. The increase in the yield point is >=0. The invention further relates to the use of the inventive films, for example in the field of medical engineering, and to bags for medical purposes that comprise at least one film according to the invention.</p> |
