UNIAXIALLY ORIENTED ARTICLE HAVING A STRUCTURED SURFACE
摘要
A process for uniaxially stretching films (9) having a structured surface comprising a geometric feature (15) is described. The process provides a film (10) in which the cross sectional shape of the feature (16) after stretching is substantially identical to the cross sectional shape of the feature (15) prior to stretching. Structured surface articles are also described. The articles have substantially the same uniaxial orientation throughout the film, including the geometric structure.
