FOERFARANDE FOER FRAMSTAELLNING AV BIAXIELLT STRAECKTA OCH MOENSTRADE FOLIER AV VINYLKLORIDPOLYMER

摘要

A process is described for the production of biaxially stretched and embossed polyvinyl chloride film, in which a polyvinyl chloride film is first stretched biaxially at specific stretching ratios and, immediately after being stretched, is embossed under specific conditions. The film produced by this process is employed with particular advantage as base film for adhesive tapes.
