Publication number: 20140327175Abstract: A die for forming a stretch film includes at least: a primary passage for receiving a primary stream, the primary passage having a length extending from a die inlet opening to a die outlet opening; and a flow assembly for supplying a secondary stream to the primary passage at a secondary passage opening. A method for forming a stretch film includes: introducing a primary stream to a primary passage of a die at a die inlet opening, the primary passage having a length extending from the die inlet opening to a die outlet opening; supplying a secondary stream to the primary passage at a secondary passage opening; combining the primary stream and the secondary stream to create a combined stream; passing the combined stream through said die outlet opening; and passing the combined stream from the die outlet opening to a casting unit, thereby forming a film web.Type: ApplicationFiled: May 1, 2014Publication date: November 6, 2014Applicant: PARAGON FILMS, INC.Inventor: Shaun Eugene Pirtle

Patent number: 8777829Abstract: 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.Type: GrantFiled: December 5, 2012Date of Patent: July 15, 2014Assignee: Paragon Films, Inc.Inventors: Shaun Eugene Pirtle, Khurrum Shamsi, Robert Earl Cochlin

Publication number: 20140144589Abstract: 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.Type: ApplicationFiled: January 29, 2014Publication date: May 29, 2014Applicant: Paragon Films, Inc.Inventors: Shaun Eugene Pirtle, Khurrum Shamsi

Publication number: 20130161860Abstract: 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.Type: ApplicationFiled: February 6, 2013Publication date: June 27, 2013Applicant: PARAGON FILMS, INC.Inventor: PARAGON FILMS, INC.

Patent number: 8100356Abstract: 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.Type: GrantFiled: May 21, 2009Date of Patent: January 24, 2012Assignee: Paragon Films, Inc.Inventors: Shaun Eugene Pirtle, Khurrum Shamsi, Robert Earl Cochlin

Publication number: 20110151217Abstract: 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.Type: ApplicationFiled: December 16, 2010Publication date: June 23, 2011Applicant: Paragon Films, Inc.Inventor: Shaun Eugene Pirtle

Publication number: 20110151216Abstract: 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.Type: ApplicationFiled: December 16, 2010Publication date: June 23, 2011Applicant: Paragon Films, Inc.Inventor: Shaun Eugene Pirtle

Patent number: 5093188Abstract: This invention relates to a single-sided cling stretch wrap film having an A/B/C structure. The surface of the A layer exhibits a high cling force to the surface of the B layer which has a high tensile strength. The surface of the C layer is cling-free. Pallet loads overwrapped with the film are neither torn or destroyed when separated from each other.Type: GrantFiled: January 8, 1990Date of Patent: March 3, 1992Assignee: Paragon Films, Inc.Inventor: Gregory L.
