Abstract: A stretched and delustered film is described which is essentially comprised of vinyl chloride polymers and which has a specific roughness, a specific luster value, a high heat shrinkage in transverse direction and a relatively low heat shrinkage in longitudinal direction and retains the delustered surface texture even on heating up to 140.degree. C. The new film is manufactured by calendering a molding composition essentially comprised of vinyl chloride polymers, and by delustering and transversely stretching the film, the calendering, delustering and transverse stretching being carried out in the order indicated and while maintaining certain process conditions. The new film is particularly suitable for skin packaging purposes.

Abstract: The present invention provides a process for the manufacture of shaped articles, especially films and sheets, having an increased white fracture effect. These articles are obtained with the use of molding compositions on the basis of vinyl chloride polymers containing from 5 to 25% by weight of elastomers and from 3 to 10% by weight of plasticizers, each relative to the total mixture.

Abstract: In a calender the nip between a pair of rollers, of which one is obliquely adjustable, is bounded at the sides by plates adapted to the geometrical shape of the nip region and provided with slots, into which a control beam, parallel to the obliquely adjustable roller, engages, the ends of the beam are joined to the bearings of this roller, and the plates are arranged on supporting plates so as to be displaceble by means of a guide device, so that the plates, on oblique adjustment of the roller, are moved along a path which is concentric with the surface of the roller which is not obliquely adjustable.
