Method and apparatus for producing polybutylene terephthalate film, and shape memory polybutylene terephthalate laminated film |
| abstract |
PROBLEM TO BE SOLVED: To provide a method and a production apparatus for producing a polybutylene terephthalate film which is a thin film and has excellent film thickness uniformity, heat shrinkage and mechanical strength. SOLUTION: In a method for producing a polybutylene terephthalate film by an air-cooled inflation method in which a tube of molten polybutylene terephthalate resin extruded from an inflation die is expanded by injecting air, the extruded resin pressure is set to 85 to 140 kg / cm 2 , And a method in which the temperature of the extruded resin is set to the melting point of the above-mentioned polybutylene terephthalate resin −15 ° C. to the above melting point −5 ° C.
