形法および水冷インフレ成形法の他に、急冷させるニア
リングを有した空冷インフレ成形法（例えば特開昭５３
−１４６７６４）等の汎用加工法が知られている。However, polypropylene film is not suitable for general-purpose processing methods such as air-cooled inflation molding, and has disadvantages such as poor impact strength (especially low-temperature impact strength) and low-temperature heat sealability. 90 Therefore, in the field of general-purpose films, high-pressure process low-density polyethylene and low-pressure process high-density polyethylene, which are resins that compensate for these shortcomings, have come to be widely used. However, these resins Although it is effective in compensating for the above disadvantages, it has the disadvantage of poor transparency. On the other hand, linear ethylene copolymers have much better impact strength, low temperature impact strength, and It is a resin with excellent mechanical strength such as environmental stress fracture (ESCR), heat sealability, hot tack properties, etc. In addition to the well-known T-die molding method and water-cooled inflation molding method, the highly transparent film of this copolymer can be molded using an air-cooled inflation molding method with a near ring for rapid cooling (for example, JP-A-53
General-purpose processing methods such as -146764) are known.
