摘要： The present invention is directed to an apparatus for differential cooling of a plastic film tube. The apparatus and method includes the use of a blown film extrusion die that extrudes a plastic film tube upward. An air cooling system applies cooling air across one or more surfaces of the plastic film tube. One or more throttling valves are coupled to a pressurization pump that provides a pressurized working fluid, preferably water. The throttling valves are positioned to project the pressurized working fluid from outlets of the throttling valves towards circular arcs of the plastic film tube, the circular arcs of the plastic film tube being less than the circumference of the plastic film tube to provide a blown film tubular plastic film with controlled gauge variation.

摘要： A method of making and using a stretchable film includes an extruding operation where molten plastics materials are extruded into a tube and a blowing operation in which the tube is blown to expand a diameter of the tube and form a blown-film tube. The blown-film tube is slit to form a film sheet that may be deformed elastically in a machine direction.

摘要： A polypropylene film which is useful for electrical devices is produced by biaxially stretching an unstretched polypropylene molded article having, on at least one side, a surface layer having .beta.-form crystals, of mean diameter over 7 .mu.m, under such conditions that the stretching temperature at the stretch initiation point is in the range of 145.degree. to 176.degree. C., and the stretch ratio in one direction is less than a factor of 8. The resulting stretched polypropylene film is characterized by excellent mechanical properties, a very dense inner structure, and high air-tightness. The surface of the film has an efficiently roughened, fine, uneven structure containing crater-like patterns or an isotropic network structure and an anisotropic network structure, which is aligned in the extrusion direction. Therefore, the polypropylene film of the present invention can be readily impregnated with insulating oils, and hence can be used in various electrical devices, such as capacitors, electric cables, transformers and the like.
