TL;DR: In this paper, a shrink wrapping material is used to protect an article from being hurled objects while it is being transported by a shrink/stretch film and a non-woven fabric.
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 non-woven layer may be treated with chemical additives to control the environment in which the article is wrapped and/or to indicate tampering.
TL;DR: In this paper, a process for preparing a holographic shrink wrap element includes providing, in the following order, a HoloPolymer film having a Holo-surface, a layer on the holographic surface and a shrink wrap film, and removing the HoloPolymyth image on the layer.
Abstract: A holographic shrink wrap element containing a shrink wrap film (3) and a layer (2) on the shrink wrap film, wherein the layer contains a holographic image. A process for preparing a holographic shrink wrap element includes providing, in the following order, a holographic polymer film having a holographic surface, a layer on the holographic surface and a shrink wrap film, and removing the holographic polymer film (1), leaving the holographic image on the layer.
TL;DR: In this paper, a packaging system in which food items can be frozen, stored, shipped, baked and served is disclosed, which includes a base, a pair of trays, a plurality of baking cups and a shrink wrap protective covering.

TL;DR: In this article, a shrink tunnel for shrink wrapping at least one product includes a housing having an interior space with a top, bottom, an entrance and an exit, and a conveyor belt passes through the interior space from the entrance to the exit.
Abstract: A tunnel for shrink wrapping at least one product includes a housing having an interior space with a top, a bottom, an entrance and an exit. A conveyor belt passes through the interior space from the entrance to the exit. The conveyor belt is substantially unobstructed on upper and lower sides and includes an opened configuration allowing substantial air flow therethrough at relatively low velocity. Heaters and air movers are located above and below the conveyor belt to uniformly heat products contained in shrink film and moving along the conveyor belt. The shrink tunnel further includes an adjustable riser member to allow a transverse section of the conveyor belt to be selectively adjusted in height from outside the housing.
TL;DR: In this article, a shrink film and hot melt are subjected to the elevated temperature of shrink oven to shrink the film and to form a more complete bond at the longitudinal seam, and the longitudinal seal is formed by swirling hot melt fibers onto a longitudinal edge of the film.
Abstract: An article is wrapped in a shrink film having a longitudinal seal. The longitudinal seal is formed by swirling hot melt fibers onto a longitudinal edge of the film and bringing longitudinal edges together to form an initial pressure-sensitive seal. The shrink film and hot melt are then subjected to the elevated temperature of shrink oven to shrink the film and to form a more complete bond at the longitudinal seam.
