Plastic film produced from synthetic resins (such as polyethylene) by the cast process. In this process, the molten resin is extruded through a slot die onto an internally cooled chill roll.
The fabrication of a film by continuously pumping the polymer through a straight slot die, then chilling this hot plastic immediately through contacts with a chilled roll. Film width is determined by how fast the chill roll pulls the film away from the die.
Plastic sheeting manufactured by the casting process, as opposed to the extruding process.
Indicates fabrication of film by continuously pumping the polymer through a straight slot orifice (die), then chilling this hot sheet of plastic immediately after the die by contact with a cooled roll. Film width is determined by the length of the slot. Thickness is determined by how fast the casting tool pulls the plastic away from the slot (or die).
A film made by depositing a layer of plastic, either molten, in solution, or in a dispersion, onto a surface, solidifying and removing the film from the surface.
(extended definition) Process that involves the extrusion of polymer melt through a slot or flat die to form a thin, molten sheet or film. This film is "pinned" to the surface of a chill roll (typically water-cooled and chrome-plated) by a blast of air from an air knife or vacuum box.
