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 stretc h films. However, pre-stretched films must generally be stretched in a separat e step and stored for several days in order for cling to fully develop. The present disclosure describes compositions, devices, systems, and methods for produci ng 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 increa se 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.
