摘要： A method and apparatus for molding an inflation film even from a thermoplastic resin having a small melt tension, in which a melt resin bubble extruded from an extruder is molded, while controlling a resin temperature of the bubble to a certain temperature range by an air ring provided with a plurality of annular slits for blowing cooling air in a take-up direction of the melt resin bubble and provided at a position at which the melt resin bubble is remarkably expanded, after (a) cooling air is blown to a melt resin bubble from a first air ring provided at the proximity of a die outlet to cool said melt resin bubble; and, then, the bubble is either (i) brought into contact, on the inner surface thereof, with the surface of a stabilizer provided on a die surface, or (ii) is supported in a non-contact state through an air layer, while being taken up.
