摘要： In the treatment of a sealable film surface by means of a flame, a film is passed over a cooling roll (4). A burner (1) is mounted above this cooling roll (4). An unpolarized flame is produced by means of this burner (1). The film is cooled by means of the cooling roll (4) and, if required, by means of additional cooling apparatuses so that the temperature of the flame-treated film surface on leaving the cooling roll (4) is not more than 25.degree. C.

摘要： A process for the production of biaxially oriented polypropylene films which include at least one layer is described, in which a propylene polymer B is heated in an extruder and the melt of the propylene polymer B is extruded through a flat sheet die and the melt emerging from the flat sheet die is taken off on one or more rolls and is solidified to give a prefilm and this prefilm is stretched in the longitudinal and transverse direction. A propylene polymer or a propylene polymer mixture A is heated and melted in a second extruder and the melt of the propylene polymer or of the propylene polymer mixture A is fed to the two sides of the propylene polymer melt B so that both melts are extruded together and simultaneously through the flat sheet die. The propylene polymer or the propylene polymer mixture A forms the edge region of the film during the production process, and the edge regions including the propylene polymer or the propylene polymer mixture A are cut off after the longitudinal and transverse stretching of the film.

摘要： A process for the production of a biaxially oriented propylene polymer film contains, in its single ply (or, if it is a multi-ply film, in its base ply) a low molecular weight resin, and the film has improved stretchability and other desirable physical properties, even though the propylene polymer of the sole or base ply is preferably a homopolymer. The n-heptane-insoluble fraction of the film has a chain isotacticity index, measured by means of .sup.13 C-NMR spectroscopy, of at least 85 to 94%. The sole or base ply contains less than 10% by weight of resin. The film is stretched in such a way that the product of tensile strength in the longitudinal and transverse direction is greater than 50,000 (N/mm.sup.2).sup.2. The film is made by, among other steps, carrying out the orientation in the longitudinal and transverse directions such that the product of the longitudinal stretching ratio and the transverse stretching ratio is.gtoreq.60.

摘要： A filter apparatus is provided comprising a number of cylindrical candle filters, each of which contains a displacement body forming a space of uniform width between itself and the candle filter. The filter material of the candle filter is supported by a cylindrical supporting body which has passages through which a plastic melt to be filtered can flow. A number of filter apparatuses can be arranged on concentric circles on a cylindrical filter housing so as to minimize the dwelling time of the plastic melt flow through the filters and to minimize the pressure loss over the length of the filters.
