ABSTRACT OF THE DISCLOSURE A blown film process wherein the temperature of the film is continually monitored in a select control or target area that is remote from the film frost line; a control or "target temperature" is determined based empirically ox otherwise on a given set of companion operating conditions; and a variable film cooling source or supply is regulated to establish the control tempera- ture as an essentially constant or non-variable operating condition. The process is characterized by an essentially stable frost line position and to the extent movement of the frost line can be optically or otherwise observed or sensed, and an appropriate signal derived therefrom, the process can be alternately practiced based on moni- toring the position of the frost line, defining a control or "target" frost line position, and regulating a film cooling source responsive to deviances or movement from the control position. 16,763B-F
