Films for packaging low-viscosity rubbers are produced from a thermoplastic moulding composition containing (essentially) a mixture of components 1 and 2, where 1 is a high-impact (graft)copolymer containing 1.1 from 95 to 85% of a vinylaromatic compound and 1.2 from 5 to 15% of a 1,3-diene, and 2 is a linear or radial block copolymer containing 2.1 from 25 to 45% of a vinylaromatic compound and 2.2 from 75 to 55% of a 1,3-diene, and from 55 to 70% of component 1 are present in the mixture of 1 and 2. The film has significantly improved tensile strength, elongation and gel content properties and is therefore particularly suitable for the intended use. |
