Directional tearing polymeric labels for clean removability
First Claim
1. A method of providing a container with a closure element which is adapted to be separated in with the opening of said container, said method comprising:
- (a) providing a sized uniaxially oriented polymer film having a discontinuity on an edge that is substantially perpendicular to the machine direction of said uniaxially oriented polymer;
(b) applying an adhesive to form a closure element bearing an adhesive; and
(c) placing on said container, said closure element bearing an adhesive, with the edge of said closure element having a discontinuity being substantially perpendicular to the direction in which sized uniaxially closure element is to separated.

Abstract
Method and elements are described for placing a closure element on a container where the closure element functions as a sanitary seal or a tamper evident seal. The (a) providing a sized uniaxially oriented polymer film having a discontinuity on an edge that is substantially perpendicular to the machine direction of said uniaxially oriented polymer; (b) applying an adhesive to at least a portion of said sized uniaxially oriented polymeric film having a discontinuity of an edge to form a closure element bearing an adhesive; and (c) placing on said container, said closure element bearing an adhesive, with the edge of said closure element having a discontinuity being substantially perpendicular to the direction in which sized uniaxially closure element is to separated.

- 17. A closure element for a container, said closure element being made of a uniaxially oriented polymeric film having a discontinuity on an edge which is perpendicular to the machine direction of the orientation of said polymeric film, said closure element being at least partially coated on one side with an adhesive.
