共重合体樹脂フィルムとをポリエチレンの溶融押出層を
介して積層したもの等がある。Among these, as a multilayer film using an unoriented polypropylene film, for example, a biaxially oriented polypropylene film (OPP) or a nylon film is used as a base film, and an unoriented propylene copolymer resin film (CPP) is used as a base film. There are those tri-laminated using an adhesive, and those in which a polypropylene base film and an unstretched propylene copolymer resin film are laminated via a melt-extruded layer of polyethylene.
しかし、無延伸ポリプロピレン系フィルムを用いた複層
フィルム、特にドライラミネートフィルムにおいては、
１！！延伸ポリプロピレン系フイルム側が滑り性不良を
起し易いという問題がある。However, in multilayer films using unstretched polypropylene films, especially dry laminated films,
1! ! There is a problem in that the stretched polypropylene film side tends to suffer from poor slip properties.

ポリプロピレン系フィルムを接着剤塗布面に接着するの
が通常である。In addition, when manufacturing the above-mentioned dry laminated multilayer film, an adhesive solution is applied to one side of a base film such as a biaxially oriented polypropylene film, and after drying, an unoriented polypropylene film is bonded to the adhesive-coated surface. It is normal to do so.

生じる。However, in this case, it is common to perform aging at high temperatures before and after tri-lamination in order to increase the adhesive strength, or because this aging can significantly reduce the slipperiness of the unoriented polypropylene film. , various constraints arise regarding the aging temperature for 1 hour.

機化合物を添加する方法などが知られている。On the other hand, as a means to improve the slipperiness of unstretched polypropylene films such as dry laminated films, saturated or unsaturated fatty acid amides having 16 to 22 carbon atoms, such as erucic acid amide and oleic acid amide, or their Method of adding derivatives (Japanese Unexamined Patent Publication No. 1983)
-85458, JP-A-62-265335, JP-A-62-265336, etc.), and methods of adding inorganic compounds such as synthetic silica and talc are known.

ィルムのトライラミネート前の滑り性、トライラミネー

難しい。[Problem M to be Solved by the Invention] However, in the method of adding fatty acid amide or its derivative described above, when a fatty acid amide other than stearic acid amide is used, slippage of the unstretched polypropylene film before tri-lamination occurs. It is difficult to simultaneously improve the wettability before tri-lamination, which is deeply related to the properties, slipperiness after tri-lamination, and adhesion to the base film.
また、ステアリン酸アミドな用いる場合でも、使用する

リン酸アミドの添加量を増加させると、ドライラミネー
ト前のぬれ性が低下し、接着強度が低下してしまう。Furthermore, even when stearic acid amide is used, since the used stearic acid amide is industrial grade stearic acid amide with a purity of about 65 to 75% by weight, if the aging temperature exceeds a certain temperature, the slipperiness after tri-lamination decreases. At this time,
If the amount of stearic acid amide added is increased in order to improve the slipperiness after tri-lamination, the wettability before dry-lamination decreases, resulting in a decrease in adhesive strength.

れないという問題があった。For this reason, when using stearic acid amide, it is necessary to limit the aging temperature to about 40°C or less and lengthen the aging time. This may cause problems with productivity and quality stability, and the aging temperature may be too low. When the aging time is low, there is a problem that sufficient peel strength cannot be obtained no matter how long the aging time is.

It is an object of the present invention to provide a propylene copolymer resin composition that can be suitably used as a constituent film material for a film.

Examples include ethylene-propylene random copolymers and ethylene-propylene-diene copolymers containing other polymers such as dicyclopentadiene. It is also possible to use a terpolymer using butene-1 or the like as a comonomer, such as an ethylene-propylene-butene-1 random copolymer. Among these various polymers, ethylene-propylene random copolymers are particularly preferred.

シール強度が低下することかある。The ethylene-propylene copolymer resin used in the present invention has an ethylene content of 1 to 10% by weight, particularly 2 to 6% by weight.
If it is less than 1% by weight, it may be difficult to heat seal, and if it exceeds 10% by weight, the heat sealing strength may decrease.

なってヒートシールが困難になることがある。In addition, it is preferable that the ethylene-propylene copolymer resin has a melting point of 110 to 150°C, particularly 125 to 145°C. If the melting point is less than 110°C, the heat sealing strength may decrease, so do not exceed 150°C. If it exceeds the limit, it may become difficult to melt and heat seal.

。Furthermore, the ethylene-propylene copolymer resin has a melt index (MI) of 1 to 20 g/10 min, especially 5 to 20 g/10 min.
Desirably, it is 10 g/10 minutes; if it is less than 1 g/10 minutes, extrusion molding becomes difficult and it may become impossible to produce an unstretched film, and if it exceeds 20 g/710 minutes, the strength of the obtained unstretched film will decrease. It may decrease.

Even if attempts were made to improve the properties of the dry laminated film by lowering the aging temperature and increasing the aging time, it was not possible to obtain sufficient peel strength, and productivity decreased due to the prolonged aging. This results in a decrease in quality, an increase in costs, and a decrease in quality stability (
