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.
Claims9
Method of protecting articles against surface damage comprising the steps of providing a wrap material consisting of a shrinkable, stretchable film first layer engaging and intermittently secured to a second layer of fibers arranged into a non-woven fabric, arranging said wrap material around said article such that the wrap material covers the article with the second layer against the article and the first layer away from the article, and applying heat to said wrap material sufficient to shrink said first layer to an extent that the second layer engages said article and prevents contact by said first layer with said article.
Method of protecting articles against surface damage comprising the steps of providing a wrap material consisting of a shrinkable, stretchable film first layer intermittently bonded to a second layer of fibers defining voids therebetween, said fibers being arranged into a non-woven fabric, arranging said wrap material around said article such that the wrap material covers the article with the second layer against the article and the first layer away from the article, and applying heat to said wrap material sufficient to shrink said first layer to an extent that the second layer engages said article, said applied heat being sufficient to expand air entrained in said voids to soften the fabric to provide a cushion supporting said first layer away from said article.
