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 woven fabric. The shrink/stretch film responds to heat by shrinking around the article being wrapped, while the woven fabric, which does not shrink or shrinks very little, forms pockets which bunch and gather up as shrinking takes place, thereby forming a cushion between the film and the object being wrapped. The woven fabric acts as a reenforcement for the film, both before and after shrinking, thus protecting the article wrapped from a hurled object and other similar hazards, and also protecting the article from direct engagement from the shrink/stretch film, which is relatively abrasive.

Procédé et matériau destinés à l'emballage d'articles par rétraction. Ce procédé consiste à emballer l'article dans un matériau d'emballage par rétraction comportant une couche externe composée d'un film rétractable/étirable, et une couche interne composée d'une étoffe tissée. Ce film rétractable/étirable réagit à la chaleur en se rétractant autour de l'article à emballer, tandis que l'étoffe tissée, qui ne se rétracte pas, ou alors très peu, forme des poches qui se ramassent et se froncent lors de la rétraction, formant ainsi un matelassage entre le film et l'article emballé. L'étoffe tissée agit comme un élément de renforcement pour le film, à la fois avant et après la rétraction, ce qui protège l'article emballé contre des objets qui y seraient projetés et autres risques similaires, et protège également l'article de tout contact direct avec le film rétractable/étirable, qui est relativement abrasif.
