Publication number: 20180094127Abstract: The present disclosure relates to a method of promoting optimal stretching of stretch film during a wrapping operation, which method comprises at least the following steps. First a resin suitable for making stretch films is selected. Then a dispersed agent is selected, preferably one which has a refractive index similar to the selected resin such that when a film is made comprising the resin and the dispersed agent, the film will appear somewhat clear. The dispersed agent is then mixed with the resin and a film is formed from the resin containing the dispersed agent. Finally, a load is manually wrapped using such film, wherein during wrapping, the film is stretched to a level where the film becomes more opaque.Type: ApplicationFiled: September 30, 2016Publication date: April 5, 2018Inventors: Justice Alaboson, Caroline Woelfle-Gupta, Rashi Tiwari, Jon W.
