摘要： Apparatus and methods for producing folded edges in a film in-process, and compositions of such film are provided. A method of folding edges includes: separating a first idler roll and a second idler roll by a first distance; positioning a plurality of folding guides between the first idler roll and the second idler roll; separating adjacent sections of film having a majority layer comprising a Ziegler Natta catalyzed linear low density polyethylene copolymer resin having molecules that inherently lack long chain branching, wherein a majority of said molecules are oriented in a substantially longitudinal direction due to an induced strain, and inducing two folds with each folding guide, thereby causing an edge of each section of film to turn under 180° and cling to a bottom surface of the section of film; and moving the adjacent sections of film from the folding guides to the second idler roll.

摘要： Pre-stretched films may be used to increase the rate at which loads can be wrapped and to minimize the exertion required when using traditional handheld film. However, the edges of pre-stretched films are easily damaged, which may result in tearing or failure of the film during use. The present disclosure describes devices, systems, and methods for folding the edges of the film, resulting in a film that is less susceptible to damage and easier to use.

摘要： Pre-stretched films may be used to increase the rate at which loads can be wrapped and to minimize the exertion required when using conventional stretch films. However, pre-stretched films must generally be stretched in a separate step and stored for several days in order for cling to fully develop. The present disclosure describes compositions, devices, systems, and methods for producing film that eliminate the stretching and storage steps. In particular, the present disclosure relates to the use of selected resins and an angled die to increase the level of orientation in the film as it is formed, thus eliminating the need to stretch the film in a separate step. The present disclosure also relates to the use of a cling agent which eliminates the storage time traditionally required to develop the film's cling properties.
