Abstract
A roll of an article, such as a film, comprising a body portion and a surface portion is provided. The body portion has (i) a first and a second surface, and (ii) first and second in-plane axes that are orthogonal with respect to each other and a third axis that is mutually orthogonal to the first and second in-plane axis in a thickness direction of the body. The surface portion comprises a geometric feature. The roll preferably has a cushioning layer between the plies of the article in the roll.
Claims21
A roll of uniaxially oriented structured surface article comprising:
- (a) a polymeric body having (i) a first and a second surface, and (ii) first and second in-plane axes that are orthogonal with respect to each other and a third axis that is mutually orthogonal to the first and second in-plane axis in a thickness direction of the polymeric film;
- and
- (b) a surface portion comprising a linear geometric feature disposed on the first surface of the polymeric body, the linear geometric feature being disposed on the body in a direction substantially parallel to the first in-plane axis of the polymeric film.
The roll of claim 11 comprising a plurality of linear geometric features disposed on the first surface of the polymeric body in a direction substantially aligned with the first in-plane axis.
A roll of a uniaxially oriented polymeric film having a length and a width, wound in the length direction comprising:
- (a) a polymeric body having (i) a first and second surface, and (ii) a first in-plane axis in the width direction of the film, a second in-plane axis in the length direction of the film and orthogonal to the first in-plane axis, and a third axis mutually orthogonal to the first and second in-plane axes in the thickness direction of the film;
- and
- (b) a surface portion comprising a linear geometric feature disposed on the first surface of the polymeric body in a direction substantially parallel to the first in-plane axis,
- wherein the film is uniaxially oriented along the first in-plane axis.
