POLYVINYL CHLORIDE FILM HAVING SPECIFIC PROPERTIES, AND A PROCESS FOR ITS MANUFACTURE

摘要

of the disclosure: 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.
