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： 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.
摘要翻译： 常规拉伸膜的问题在于，膜的边缘可能容易损坏，这可能导致膜在使用过程中的撕裂或破裂。 折叠胶片边缘可能减少这种损伤，但会产生难以展开的不均匀的胶卷卷。 本公开描述了用于振荡膜的过程中装置，系统和方法，以防止当膜卷绕在胶卷上时折叠边缘的堆叠。 本公开还描述了当膜被卷绕到膜卷上时在膜层之间捕获空气的过程中装置，系统和方法。 因此，该膜不易受到损伤并易于使用。

摘要： The present disclosure generally relates to compositions and methods for incorporating higher density metallocene linear low density polyethylene (m-LLDPE) into cast power stretch films. When compared to conventional machine films on a gauge-by-gauge basis, films containing the properly selected m-LLDPE may offer increased load containment force, reduced application force, and comparable elongation and puncture resistance properties.

摘要： The present disclosure describes compositions, devices, systems, and methods for producing films which simplify the application process by eliminating the need to stretch film before it is wrapped around a load. Such films also provide enhanced load containment and increased resistance to punctures and breaks. 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.

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.
