Abstract
An article comprising an expanded polyethylene substrate (12) having a longitudinal length, a first zone (14), and a second zone (16). The first zone having a first density and the second zone having a second density, the second density being greater than the first density, and the second zone is embossed.
Claims24
An article comprising:
- an expanded polyethylene substrate having a longitudinal length, a first zone and a second zone, wherein the first zone has a first density and the second zone has a second density, the second density being greater than the first density, and
- wherein the second zone is embossed.
A method of forming an article, comprising:
- selectively densifying a portion of an expanded polyethylene substrate to form one or more densified portions of the expanded polyethylene substrate, wherein the expanded polyethylene substrate has one or more un-densified portions with a first density, and wherein the one or more densified portions have a second density that is greater than the first density, wherein the one or more densified portions are arranged adjacent to the one or more un-densified portions.
A method of forming an article, comprising:
- compressing an expanded polyethylene substrate in a longitudinal and/or lateral direction such that the expanded polyethylene substrate is in a longitudinally and/or laterally compressed state, the expanded polyethylene substrate having a first density;
- selectively densifying a portion of the expanded polyethylene substrate when in the longitudinally and/or laterally compressed state to form a densified portion of the expanded polyethylene substrate, wherein the densified portion includes a second density that is greater than the first density;
- and
- releasing the expanded polyethylene substrate from the longitudinally and/or laterally compressed state.
