    摘要: The present invention relates to single- or multilayer films and one or more layers comprising at least one polyolefin molding composition containing at least one polyolefin derived from at least one olefin having at least 2 carbon atoms, of the formula Ra—CH═CH—Rb, in which Ra and Rb are identical or different and are a hydrogen atom or a straight-chain or branched C1-C15-alkyl radical, or Ra and Rb, together with the atoms connecting them, form a ring or ring system, and the polyolefin has been prepared by means of metallocene catalysts. The present invention furthermore relates to a process for the production of films and layers in which a polyolefin molding composition having a particle size of from 20 &mgr;m to 5000 &mgr;m is used or prepared. The shaped polyolefin molding composition is melt-mixed with at least one additive and shaped. The melt-mixed and shaped material is melted at a temperature of from 150° C. to 300° C. The molten material is cooled and at the same time shaped to give a film or layer. Finally, the present invention also relates to the use of films and layers for the production of articles such as bags, composite materials and laminates.
