Abstract
A method and material for shrink wrapping articles includes wrapping the article with a shrink wrapping material having a shrink/stretch film outer layer and an inner layer of a non-woven fabric. The shrink/stretch film responds to heat by shrinking around the article being wrapped, while the non-woven material aerates to form bubbles thus acting as a cushion between the shrink/stretch film outer layer and the article being wrapped. Accordingly, the article being wrapped is protected during the shrinking process, and is also protected from hurled objects while the article is being transported. The nonwoven layer may be treated with chemical additives to control the environment in which the article is wrapped and/or to indicate tampering.
