Description

  

  Verfahren zur Herstellung von     luft-    und wasserdichtem Verpackungsmaterial.    Gegenstand vorliegender Erfindung ist ein  Verfahren zur Herstellung von     luft-    und was  serdichtem     Verpackungsmaterial,    das sich un  ter anderem vorzüglich eignet zum Einwickeln  von     Nahrungs-    und Genussmitteln, die der Ein  wirkung der sie umgebenen Atmosphäre ent  zogen werden müssen.

   Als solche kommen  hauptsächlich in Betracht: Tee, Kaffee, Kaffee  surrogate, Vanille, gewisse Arten von beson  ders gegen Feuchtigkeit empfindlichen     Cerea-          lenprodukten        etc.    Dieses Verfahren besteht  darin, dass man faserige Substanzen in Blatt  form in einem Harzbad     tünkt,    worauf man  sie beidseitig mit einer nicht klebrigen Schicht  belegt.  



  Als faserige Substanzen in Blattform kom  men Papier und Gewebe aller Arten, sowie  Karton in Frage.  



  Je nach der Verwendungsart des fertigen       Verpackungsmaterials    wird man für die nicht  klebrige Schicht entweder Papier, Karton oder  Gewebe nehmen. In gewissen Fällen aber  wird man sich auch begnügen, die Harz  schicht mit einem Überzug von fein pulveri  sierten Substanzen, wie Sand, Talg oder  Kreidemehl, zu versehen. Zur Fabrikation    dieses Verpackungsmaterials kann man zum  Beispiel wie folgt verfahren  Papierblätter werden in einem     Kolopho-          niumbad    getunkt, der auf irgend eine unge  fährliche Art, zum Beispiel durch Dampf oder  Elektrizität, erwärmt worden ist. Bevor der  Überzug wieder vollständig hart ist, wird das  Papierblatt     beidseitig    mit einem neuen Blatt  belegt und das Ganze so getrocknet.  



  Will man eine gewisse Geschmeidigkeit  der Verpackung erzielen, so muss man dafür  sorgen, dass das Kolophonium nicht vollstän  dig erhärtet. Das erreicht man durch Beigabe  von Öl und Paraffin im     Kolophoniumbad.     



  Wenn eine besondere Zähigkeit der Ver  packung verlangt wird, so wird das Papier  beidseitig mit einem feinen Gewebe, aus  Baumwolltuch zum Beispiel, belegt. Auch  kann es vorkommen, wenn das Verpackungs  material nicht mit einer besondern Hülle auf  den Markt kommen soll, dass die faserige  Substanz in Blattform, also Papier oder Ge  webe zum Beispiel, einseitig mit Karton,     an-          derseitig    mit Papier oder wiederum Gewebe  belegt wird, nachdem sie das Kolophonium  bad passiert hat.

        Das     Verpackungsmaterial    kann auch auf       kapern    Wege fabriziert werden: Das Harz  bad bestellt dann aus Kolophonium in einem       verflüchtigbaren    Lösungsmittel,     Alkohol        zum          Beispiel.    Nachdem die faserige Substanz in  Blattform darin gebracht wurde, wird sie vor  der Verflüchtigung des Lösungsmittels mit  einer     hiebt    klebrigen Schicht bedeckt. Diese       Verflüehtigurig    kann zum Beispiel durch     Va-          kurun    befördert werden.



  Process for the production of airtight and watertight packaging material. The present invention is a process for the production of airtight and watertight packaging material, which is, inter alia, ideally suited for wrapping food and luxury items that must be withdrawn from the action of the surrounding atmosphere.

   The main ones that come into consideration are: tea, coffee, coffee surrogates, vanilla, certain types of cereal products that are particularly sensitive to moisture, etc. This process consists in dipping fibrous substances in leaf form in a resin bath and then putting them on both sides covered with a non-sticky layer.



  All types of paper and fabric, as well as cardboard, can be used as fibrous substances in sheet form.



  Depending on the type of use of the finished packaging material, either paper, cardboard or fabric will be used for the non-sticky layer. In certain cases, however, you will be content to provide the resin layer with a coating of finely pulverized substances, such as sand, tallow or chalk flour. This packaging material can be manufactured as follows, for example. Paper sheets are immersed in a rosin bath that has been heated in some harmless way, for example by steam or electricity. Before the coating is completely hard again, the paper sheet is covered on both sides with a new sheet and the whole thing is dried in this way.



  If you want to achieve a certain suppleness in the packaging, you have to make sure that the rosin does not harden completely. This can be achieved by adding oil and paraffin to the rosin bath.



  If a special toughness of the packaging is required, the paper is covered on both sides with a fine fabric, made of cotton cloth, for example. It can also happen, if the packaging material is not to come onto the market with a special cover, that the fibrous substance in sheet form, i.e. paper or tissue for example, is covered on one side with cardboard, on the other side with paper or tissue, after passing the rosin bath.

        The packaging material can also be manufactured in a pirate manner: The resin bath is then made of rosin in a volatile solvent, alcohol for example. After the fibrous substance in sheet form has been placed in it, it is covered with a sticky layer before the solvent evaporates. This volatilization can be promoted, for example, through Vakurun.
