Disclosed are a method, a device and/or a system of cast vinyl film and, more particularly, to a method and system to provide a repositionable translucent cast vinyl film with an air egress adhesive layer. In one aspect, a method includes mixing a solvent based polyvinyl chloride (PVC) organosol with a stabilizer and an additive to get a desired shade of pellucid tint of a translucent thermoplastic stretch wrap film. Further, the method includes casting the polyvinyl chloride (PVC) organosol onto a film carrier and moving the film carrier through a plurality of ovens at varying temperatures to care into a solid film. The cured solid film is laminated to an air-egress liner casted with a solvent-borne acrylic pressure-sensitive adhesive to provide ease of installation. The adhesive includes an air release patterning to allow escape of air from back of the film while repositioning the film around a complex shaped surface.
