Kind Code:
A
Abstract:
Uniaxially Oriented Articles Having Structured Surface A process for uniaxially stretching films is having a structured surface comprising a geometric feature is described. The process provides a film in which the cross sectional shape of the feature after stretching is substantially identical to the cross sectional shape of the feature prior to stretching. Structured surface articles are also described. The articles have substantially the same uniaxial orientation throughout the film, including the geometric structure. Uniaxially oriented articles having structured surfaces are described. The articles have dimensional relationships as follows: the (a) ratio of the thickness of the body (Z') to the height of the geometric feature (P') is at least about 2; or (b) the ratio of body thickness to feature height (Z':P') is at least about 1 and the ratio of feature height to feature separation (P':FS') is at least about 1; or (c) the ratio of body thickness to feature height (Z':P') is at least about 1 and the ratio of feature base width to feature separation (BW':FS') is at least about 1; or (d) the ratio of body thickness to feature base width (Z':BW') is at least about 3; or (e) the ratio of body thickness to feature base width (Z':BW') is at least about 1 and the ratio of feature height to feature separation (P':FS') is at least about 1; or (f) the ratio of body thickness to feature base width (Z':BW') is at least about 1 and the ratio of feature base width to feature separation (BW':FS') is at least about 1; or (g) the ratio of feature base width to feature top width (BW':TW') is at least about 2 and the ratio of feature base width to feature separation (BW':FS') is at least about 1.
