摘要： According to the improved process sheets of thermoplastic material are embossed especially on both faces by means of a pair of embossing rollers in such a manner that the embossing roller is maintained at a temperature within the plastic temperature range of the thermoplastic material, and the sheet forwarded to the roller has a temperature in the range of from the second order transition temperature of the thermoplastic material and a temperature superior to it by about up to 70.degree. C.; the sheet being forwarded at a speed of from 5 to 200 m/min and subjected to an embossing pressure of from 100 to 500 N/cm. This process prevents undesirable alteration of the pattern first embossed in the second embossing operation in the case of double-face embossment of the sheet. The embossed sheets may be applied for decoration purposes or the coating of furniture, as well as for writing.

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.

摘要翻译： 描述了用于生产双轴拉伸和压花的聚氯乙烯膜的方法，其中首先以特定拉伸比双轴拉伸聚氯乙烯膜，并且在拉伸后立即在特定条件下压花。 通过该方法生产的膜特别有利于胶带的基膜。
