摘要： A connection method and connection apparatus for connecting long belt-shaped non-oriented resin films that are continuously advanced. A leading resin film and a trailing resin film can be connected while processing in a following step is continuously performed. The tip end of a trailing resin film (22) is joined and connected to a leading resin film (11), and then a portion, immediately after the connected position, of the leading resin film is heated to a predetermined temperature range and cut.

摘要： A process for producing amultilayeredunstretched film. The process is intended to minimize the amount of those thick parts of a film formed which are to be discarded, and to thereby attain a cost reduction. Thermoplastic resins (20A) and an extra thermoplastic resin (20B) different from the thermoplastic resins (20A) are separately melted by heating. Immediately before widening in respective manifolds, the extra thermoplastic resin is introduced to each edge part of each of the objective thermoplastic resins. The resins are fed to and widened in the manifolds so that the extra thermoplastic resin is disposed on the side of each edge of each objective thermoplastic resin. Subsequently, the melts are joined and ejected from the die lip of the T-die on a casting roll. Thus, a multilayered unstretched film is formed which comprises multilayered thermoplastic resins made of the objective thermoplastic resins and the multilayered extra thermoplastic resin disposed on the side of each edge of those multilayered resins. Thereafter, the parts constituted of the extra thermoplastic resin are removed by cutting to form a multilayered unstretched film (20) consisting mainly of the objective thermoplastic resins.

摘要： Provided are a multilayer film comprising a plurality of resin layers having melt viscosities at the same heating temperature being different from one another, wherein it is a multilayer resin film which is reduced in the irregularity of the surface thereof; and a method for producing a multilayer resin film which comprises laminating a plurality of resins having melt viscosities at the same heating temperature being different from one another, without the formation of irregulars ties on the surface of the film. A method for producing a multilayer resin film, wherein a plurality of resins having melt viscosities at one heating temperature being different from one another are laminated, by the use of a multi-manifold die, which comprises controlling respective temperatures of an extruder provided connected to a manifold, the manifold, a die adjacent to the manifold, through which the above plural resins are passed, in such a manner that the difference of the melt viscosities of adjacent resin layers is 3000 poise or less at a shear rate of 20 to 500 sec -1 , and then laminating the respective molten resins, to form a multilayer film.
