めである。The polyethylene resin in the synthetic resin component, which is the raw material for film formation, does not impair the physical properties of the film obtained by the thermoplastic polyester resin, and is suitable for thermoplastic polyester resins. The resin "takes a very long time to recrystallize once melted", "the surface of the molded product is highly sticky between melting and recrystallization", "tension and viscosity during melting are low", etc. The amount of polyethylene resin blended and its type are determined based on the crosstalk with the thermoplastic polyester resin, which is the other component used as a synthetic resin component, and the physical properties required for the resulting film. It is blended in such a way that it accounts for 80 to 5% by weight of the total resin components, taking into consideration the physical properties and the performance of the inflation film forming machine used. This means that if the blending amount of polyethylene resin is less than 5M%, the thermoplastic polyester resin will be
Once melted, it takes a very long time to recrystallize.
Insufficient modifications such as "high adhesiveness on the surface of the molded product during the period from melting to recrystallization" and "low tension and low viscosity during melting", and that the amount of polyethylene resin blended is 80% by weight If it exceeds the range, the properties of the resulting single-layer film will be far different from the physical properties of the thermoplastic polyester resin film, and it will become impossible to obtain a single-layer film having the properties inherent to the thermoplastic polyester resin film.

なった。For reference, we attempted to melt and extrude a saturated thermoplastic polyester resin (Vylon GM-900) at a temperature of 115 to 140°C to form a film, but the tension during melting of the resin was small, and the tubular film was pinch-rolled. Not only was it difficult to pull the film up to 3 and 4, but during the film forming process, the film 5 strongly adhered to the surface of the metal row/L (pinch roll 3) and the rubber roll (pinch roll 4). The film forming machine became unable to operate.

作用、効果を奏する。As explained above, the present invention provides a method for producing a synthetic resin film in which a monolayer film of a thermoplastic polyester resin to which a polyethylene resin having an ethylene content of 50% by weight or more is added as a modifier is obtained by an inflation method; That is, it contains 20 to 95% by weight of thermoplastic polyester resin and polyethylene chains, and has an ethylene content of 5% by weight.
A method for producing a single layer film made of synthetic resin, in which a raw material for film forming, whose synthetic resin component is a mixed resin with 80 to 5% by weight of polyethylene resin of 0i% or more, is subjected to film forming by an inflation method, The addition of the polyethylene resin does not impair the original properties of the thermoplastic polyester film in the resulting synthetic resin single-layer film. We have improved the disadvantages of inflation film molding, such as "it takes a long time", "the surface of the molded product (film) is highly sticky between melting and recrystallization", and "low tension and viscosity during melting". As a result, it is possible to stably obtain a single-layer synthetic resin film having the properties of a thermoplastic polyester film using an efficient inflation method.

ことが出来るという作用、効果を有する。However, in the method for producing a single layer synthetic resin film having the properties of a thermoplastic polyester film of the present invention, the amount of polyethylene resin in the film forming raw material influences the surface adhesive properties of the resulting film. A synthetic resin film with the desired surface adhesion depending on the application,
It has the function and effect that it can be easily obtained by changing the ratio between the thermoplastic polyester resin and the polyethylene resin in the film forming raw material.
