    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.
