Abstract: Plastic bag (WB) containing stacked soft hygienic products (FCS), e.g. sanitary napkins, panty liners, diapers, or the like, which can be made on-line from a roll of film. The plastic bag comprises one MD seal (35) along one closure corner (46) and is without a fold line in the center of a side panel. An artwork may be present which is continuous in the area of the MD seal. The products may be in a compressed state in the closed plastic bag.

Abstract: Roentgen lithography aparatus comprises a roentgen tube for producing long wave roentgen radiation for forming an image of a mask on a substrate. The roentgen tube comprises an electron gun having a glow cathode and a grid, electron beam deflecting and focussing coils, a target on which the electron beam is projected and an exit window through which roentgen rays from the target are projected through a lithography mask onto a substrate. The glow cathode and the target are of high atomic number high melting point material, such as tunsten. The grip has an annular flange with a central opening in which the tip of the glow cathode is disposed. The front face of the flange facing the target is frustoconical with an included angle of about 100.degree. to 140.degree. while the rear face is plane. The angle between the front and rear faces as measured in a radial plane is about 15.degree. to 60.degree.. The focussing coil focusses the electron beam into a focal spot on the target having a diameter less than 10.sup.
