摘要： An inflation film is formed by extruding a raw resin in a molten state through a circular die to form a tubular film, expanding the tubular film by the pressure of a gaseous medium introduced into an inner space of the tubular film, while the tubular film is being cooled to be solidified by blowing a cooling gas to the outer surface of the tubular film, and drawing the film while being progressively flattened by guide members. During the manufacture, the temperature Tf (null C.) of the solidified tubular film at the time it contacts the guide member for the first time is so adjusted as not to be higher than Tr (5) nullnull C.null; wherein Tr (5) represents the temperature at which the thermal deformation ratio of the solidified tubular film becomes 5% when it is measured, being loaded with a stress of a value equal to the frictional force received from the guide members under the conditions of manufacture of the film.
