    Abstract: A mixture comprising a) 5 to 95 wt.-% of a copolymer A that contains one or more copolymer blocks (B/S)
    A , each made of 65 to 95 wt.-% of vinyl aromatic monomers and 5 to 35 wt.-% dienes and having a glass transition temperature Tg
    A in the range of 40° to 90°C, b) 5 to 95 wt.-% of a block copolymer B containing at least one hard block S made of 95 to 100 wt.-% of vinyl aromatic monomers and 0 to 5 wt.-% dienes, one or more copolymer blocks (B/S)
    A , each made of 65 to 95 wt.-% of vinyl aromatic monomers and 5 to 35 wt.-% dienes and having a glass transition temperature Tg
    A  in the range of 40° to 90°C and one or more copolymer blocks (B/S)
    B , each made of 20 to 60 wt.-% of vinyl aromatic monomers and 40 to 80 wt.-% dienes and having a glass transition temperature Tg
    B in the range of –70° to 0°C, c) 0 to 45 wt.-% of A and B of various thermoplastic polymers C and d) 0 to 6 wt.-% of processing aids D, wherein the total of A through D is 100 wt.-%, and use thereof for the production of shrink-wrap films.
