Description
Schutzhülle für licht- bezw. luftempfindliche Waren aller Art. Gegenstand der Erfindung ist eine ver besserte Schutzhülle für licht- bezw. luftemp findliche Waren aller Art, insbesondere Le bensmittel, Bücher Textilwaren usw.
Es ist bekannt, derartige Hüllen, die aus Folien aus polymere organische Stoffe ent haltenden Massen z. B. Papier, regenerierter Zellulose, oberflächlich verseiftem Zellulose azetat usw. bestehen, mit einer Lösung von Äskulin oder Chininsulfat zu tränken, um sie für ultraviolette Strahlen undurchlässig zu machen. Die so hergestellten Schutz hüllen haben jedoch den Nachteil, dass sie unter der Einwirkung von Feuchtigkeit die ihnen einverleibten Zusätze wieder abgeben. So kann z. B. durch die Feuchtigkeit von in derartigen Hüllen verpackten Lebensmit teln ein Teil der genannten Zusätze auf die Lebensmittel übertragen werden.
Erfindungsgemäss wird dieser Nachteil vermieden, indem man zur Absorption der ultravioletten Strahlen der Folie solche Kör per einverleibt, die nicht nur die erforder lichen optischen Eigenschaften aufweisen, son dern ausserdem substantiven Charakter be sitzen und daher fest auf das zur Herstellung der Schutzhülle verwendete Folienmaterial aufziehen und durch Feuchtigkeit nicht mehr herausgelöst werden können.
Gegebenenfalls können den in dieser Weise mit ultravioletten Strahlen absorbierenden gefärbten oder farblosen Körpern versetzten Folien auch noch Körper zugesetzt werden, die, wie z. B. Hydrochinon, Oxydation der erstgenannten Körper verhindern.
<I>Beispiel 1:</I> Eine Folie aus Gelatine wird bei gewöhn licher Temperatur mit einer 2 o/oigen Lösung von Primulin getränkt. Die Folie kann ohne Schaden gewässert werden. Zur Herstellung der erforderlichen Geschmeidigkeit kann nach dem Wässern in an sich bekannter Weise eine Behandlung mit Glyzerin vorgenommen werden.
<I>Beispiel 2:</I> Eine Folie aus regenerierter Zellulose wird bei \.70 0 C mit einer 2-5 %igen wäs- serigen Lösung des Harnstoffes aus p-Amino- benzoyl-p-phenylendiaminsulfosaurem Natrium getränkt.
Gegebenenfalls können der Lösung ausserdem 1-5 % Hydrochinon zugesetzt werden. Eine Nachbehandlung mit Glyzerin zur Erhöhung der Geschmeidigkeit kann statt finden.
<I>Beispiel 3:</I> Eine Folie aus regenerierter Zellulose wird mit einer wässerigen Lösung von di- m-aminobenzoyl - diaminostilbendisulfosaurem Natrium getränkt, gewässert und darnach mit einem Glyzerinbad behandelt.
Protective cover for light or air-sensitive goods of all kinds. The invention is an improved protective cover for light respectively. All kinds of air-sensitive goods, in particular food, books, textile goods, etc.
It is known, such shells, made of films of polymeric organic substances ent containing masses z. B. paper, regenerated cellulose, superficially saponified cellulose acetate, etc. exist to soak with a solution of aesculin or quinine sulfate to make them impermeable to ultraviolet rays. The protective covers produced in this way, however, have the disadvantage that they release the additives incorporated into them under the action of moisture. So z. B. by the moisture of food packaged in such cases, some of the additives mentioned are transferred to the food.
According to the invention, this disadvantage is avoided by absorbing the ultraviolet rays of the film by incorporating those bodies that not only have the required optical properties, but also have substantive character and are therefore firmly attached to the film material used to produce the protective cover can no longer be removed by moisture.
If necessary, the colored or colorless bodies offset in this way with ultraviolet rays absorbing films can also be added bodies which, such as. B. Hydroquinone, prevent oxidation of the former body.
<I> Example 1 </I> A film made of gelatin is soaked in a 2% solution of primulin at the usual temperature. The foil can be soaked in water without damage. In order to produce the necessary suppleness, treatment with glycerine can be carried out in a manner known per se after soaking.
<I> Example 2 </I> A film made of regenerated cellulose is impregnated at 70 ° C. with a 2-5% strength aqueous urea solution of p-aminobenzoyl-p-phenylenediaminesulfonic acid sodium.
If necessary, 1-5% hydroquinone can also be added to the solution. A follow-up treatment with glycerine to increase the suppleness can take place.
<I> Example 3: </I> A film made of regenerated cellulose is impregnated with an aqueous solution of dim-aminobenzoyl-diaminostilbene disulfonic acid, watered and then treated with a glycerine bath.
