 vinylchlorid verrührt. Dann wird die so erhaltene Mischung auf einer heissen Walze (1600 C Walzentemperatur) ausgewalzt. Die so erhaltene Folie ist wirksam gegen : Staphylococcus   aureus,   Bacterium typhi, Streptococcus lactis, Candida albicans, Trichophyton pedis, Bacterium cremoris, Bacterium subtilis, Bacterium coli, Aspergillus niger, Penicillium glaucum, Chaetomium globosum. 



     Beispiel 2 ;   Eine Lösung bzw. Dispersion von   2, 5 Gew.-Teilen Zinkpentachlorphenolat   und 2, 5   Gew. -Teilen SaUcylanilid wú : d mit 22 Gew. -Teilen Dioctylphthalat   und 73   Gew.-Teilen   Polyvinylchlorid verrührt. Die so erhaltene Mischung wird bei einer Walzentemperatur von 160 bis 1650 C zur Folie ausgewalzt. Die Folie hat bei verstärkter Wirkung gegenüber gram-negativen Keimen   (Escher1chia- und   Salmonella-Typen) sonst die gleichen   Hemm- bzw. Abtötewerte   wie eine in Beispiel 1 genannte Folie. 



  Sie zeichnet sich aber durch eine bessere Beständigkeit gegen Verfärbungen im Licht aus.

 vinyl chloride stirred. The mixture thus obtained is then rolled out on a hot roller (roller temperature of 1600 ° C.). The film obtained in this way is effective against: Staphylococcus aureus, Bacterium typhi, Streptococcus lactis, Candida albicans, Trichophyton pedis, Bacterium cremoris, Bacterium subtilis, Bacterium coli, Aspergillus niger, Penicillium glaucum, Chaetomium globosum.



     Example 2; A solution or dispersion of 2.5 parts by weight of zinc pentachlorophenolate and 2.5 parts by weight of sucylanilide was stirred with 22 parts by weight of dioctyl phthalate and 73 parts by weight of polyvinyl chloride. The mixture obtained in this way is rolled out at a roller temperature of 160 to 1650 C to form a film. With an increased action against gram-negative germs (Escherchia and Salmonella types), the film otherwise has the same inhibition or destruction values as a film mentioned in Example 1.



  However, it is characterized by better resistance to discoloration in the light.
