Abstract
A film comprises at least one PVC polymer and at least one plasticizer and further comprises from 2 to 25 parts by weight of an additive polymer in the form of a crosslinked or PVC-incompatible polymer per 100 parts by weight of the PVC polymer and from 25 to 37 parts by weight of a polymer plasticizer per 100 parts by weight of the PVC polymer, excluding the additive polymer. As a result, it combines high stretchability with good hand tearability and permits the production of advantageous adhesive tapes, especially self-adhesive masking tapes.

A film comprising at least one PVC (polyvinyl chloride) polymer and at least one plasticizer, further comprising from 2 to 25 parts by weight of an additive polymer in the form of an inherently crosslinked or PVC-incompatible polymer per 100 parts by weight of said at least one PVC polymer and from 25 to 37 parts by weight of a polymer plasticizer per 100 parts by weight of said at least one PVC polymer, provided that when said addiive polymer is a crosslinked PVC, said at least one PVC polymer is uncrosslinked.
