    Abstract: The present disclosure relates to a multilayer stretch film comprising at least a first layer, wherein said first layer comprises a polyolefin resin. The film of this aspect of the disclosure further include at least a second layer, and a mechanochromic dye which may be in any or all layers of the film. Another aspect of the disclosure is a method of promoting optimal stretching of stretch film during a wrapping operation, which method comprises at least the following steps. A polyolefin resin is selected that has a given density. Selecting a mechanochromic dye based on its ability to agglomerate in an unstretched film made from the polyolefin resin having the given density, such that when the dye is included in the film, the unstretched film will exhibit a first color. Admixing the mechanochromic dye into a melt of the polyolefin resin. Forming a film from the admixture of the previous step. Wrapping an object using the film of the previous step, while stretching the film to a level where a change from the first color to a second color can be observed.
