## Abstract

A polymeric sheet having low density and comprising a low to non-existent amount of cyclic olefinic polymers (COP) and/or cyclic olefinic copolymers (COC). The overall density of the sheet may be lower than water. The sheet may be stretched and then heat shrinked onto an article. The sheet may be used as a label or package to wrap articles therewith.

## Claims

### Claim 1

An article comprising:
a polymeric film roll;
wherein the film roll comprises:
a polymeric film;
wherein the film:
(i) has a density less than 1 g/cm3; and
(ii) is configured to be:
a) shrinkable in a machine direction of the film roll by at least 15% upon exposing the film to 100 degrees Celsius with a steam tunnel,
b) shrinkable in a transverse direction of the film roll by less than 5% upon exposing the film to 100 degrees Celsius with a steam tunnel, and
c) used as a sheet in a machine direction labeling system.

### Claim 2 (depends on 1)

The article of claim 1:
wherein the polymeric film comprises at least one polymer selected from the group of polymers consisting of cyclic olefinic polymers, cyclic olefinic copolymers and combinations thereof; and
wherein the amount of the polymers is less than 40%.
