Abstract
An issue with conventional stretch films is that the edges of the film can be easily damaged, which may result in tearing or failure of the film during use. Folding the film edges may reduce such damage but yields uneven rolls of film that are difficult to unwind. The present disclosure describes in-process devices, systems, and methods for oscillating the film to prevent stacking of the folded edges as the film is wound onto a film roll. The present disclosure also describes in-process devices, systems, and methods for entrapping air between the layers of film as they are wound onto a film roll. As a result, the film is less susceptible to damage and easier to use.
