Definitions

  • the invention further relates to a device and the use of the method.
  • containers for example for foodstuffs, foodstuffs and luxury foods, with a lid in the form of a film or a sealing membrane, in order to protect the contents of the container from spilling out, leakage, the influence of substances from the outside and from spoilage.
  • Such containers are, for example, cups, bowls, tapestries, portion packs, etc.
  • the lids are, for example, foils or foil composites made of metals, plastics, paper or combinations thereof.
  • Milk or milk products such as thick milk, buttermilk, sour milk, cream, cream, sour cream, curd cheese, curd cheese, yoghurt, pudding and other foodstuffs and food preparations, as well as food preparations, can be filled into the containers.
  • one of the filling methods is that the containers are delivered to a filling station and the containers are filled with the contents. After filling, the container is covered. From a supply of lids, and in particular a stack of lids that have already been pre-punched to their final size, a lid is gripped - usually by machine -, brought into line with the edge of the container and sealed or glued to the edge of the container.
  • embossing the cover film which can be present, for example, as continuous goods or in rolls or in formats before the individual covers are punched out.
  • Embossing patterns that are usually used are needle embossing, the so-called worm embossing or the dot embossing.
  • the finished, punched-out cover can have a bending or rolling tendency that results from the stretching process before, after and during the Embossing and the "memory" inherent in the lid film to the originally rolled position.
  • This bending and rolling tendency stands in the way of mechanical covering and the closing process, such as an adhesive or sealing process.
  • the individual cover or the cover film or the sealing membrane must therefore have a high flatness.
  • the object of the present invention is to propose a method for the production of lids or sealing membranes which can be easily separated from a stack, the lids or sealing membranes having a high flatness and no or only a slight tendency to bend, bulge or roll.
  • this is achieved in that the cover film 1 is passed through a pair of embossing rollers 4 in a first embossing step and a first embossing is applied from one side and in a second embossing step the cover film is passed through a second pair of embossing rollers 9 and a second embossing of the other side is applied and the embossing pressures of the first and second embossing roller pairs 4, 9 can be set independently of one another and the embossed and punched sealing membranes 17 are checked continuously or intermittently for their flatness and, if the flatness is insufficient, the pressure of the first or second embossing roller pair 4 , 9 or both embossing roller pairs 4, 9 is changed to such an extent that the flatness for the subsequently embossed sealing membranes 17 is established.
  • Cover films which are particularly suitable for the present process can contain, for example, plastics, metals or paper or combinations thereof.
  • the plastics and metals are preferably used in film form or in the form of film composites.
  • the paper can, for example, be laminated or be part of a film composite.
  • the cover foils can be printed, provided with a counterprint or colored through and may have top and protective varnishes.
  • the plastics can also be used as extrusion layers.
  • Polyolefins such as polyethylenes and polypropylenes; Polystyrene; Polycarbonates; Polyamides; Polyesters such as polyethylene terephthalates and polyvinyl chlorides.
  • the plastics can be used as monofilms or as film composites, the film composites optionally also in combination with metal foils or papers.
  • Foil composites can be produced by lamination or extrusion.
  • Adhesion promoters and laminating adhesives such as acrylate adhesives or one- or two-component polyurethane adhesives, can be used between the layers of plastics and possibly metal foils, papers etc.
  • the cover films made of the plastics mentioned can have at least one barrier or barrier layer made of ceramic material, for example made of silicon oxides or aluminum oxides.
  • the ceramic material is applied in particular by evaporation in a vacuum and deposition on the plastic onto the film in thicknesses of, for example, 5 to 500 nm (nanometers). Such methods are known as chemical vapor deposition (CVD), physical vapor deposition (PVD) or sputtering. It is possible to use metal foils and in particular aluminum foils, typical thicknesses of such metal foils ranging from 6 to 100 ⁇ m and advantageously from 8 to 50 ⁇ m. The aluminum foils can be covered on one or both sides with plastic layers and / or lacquers. The metal foils also have an excellent barrier effect.
  • Both or at least one side, and preferably the underside of a cover film can have a cold or in particular hot sealable layer, such as a sealing layer, a sealing film or a sealing wax.

  • the pressure can be generated by mechanical, pneumatic or hydraulic means, with pneumatic pressure being preferred.
  • the pressurization can be controlled manually, mechanically or electronically.
  • the electronic control can with signal transmitters, which the flatness resp. Rolling tendency or bulge of the sealing membranes just manufactured are connected.

  • the flatness can be determined continuously, that is to say on each sealing membrane, for example immediately after punching out, or the flatness can be checked periodically, in each case by checking a sample according to a predetermined or arbitrarily selected number of punched-out sealing membranes. If the sealing membranes show a bulge on the upper side, the pressure of the first pair of rollers can be reduced and / or the pressure of the second pair of rollers can be increased in the process described. If the flatness then arises, these pressure ratios of the roller pairs are maintained until there is another deviation from the flatness.
  • the pressure of the first pair of rollers is increased and the pressure of the second pair of rollers is reduced until the generated sealing membranes are flat again.
  • the pressure of the first pair of rollers is preferably left unchanged as far as possible and the upward or downward curvature of the sealing membranes is controlled only via the second pair of rollers in order to keep the number of parameters as small as possible. If a flat position of the sealing membranes is no longer achieved with the pressure control of the second pair of rollers, the pressure of the first pair of rollers can of course be included in the process.
