Abstract
In one example, a structure includes a flexible plastic body having a first end and a second end, as well as a first side and a second side disposed opposite each other. The first side includes a first group of segments, and the second side includes a second group of segments. The structure also includes a group of living hinges integral with the body, and one of the living hinges is positioned between segments, and the living hinges enable the flexible plastic body to alternatively assume a flat state, or another state in which the body is not flat.
