。Polyvinyl alcohol resin film has extremely low permeability to gases other than water vapor, so its gas barrier properties can be used to create gaskets, hoses, diaphragms, etc.
It is used for various purposes such as packaging sheets. When used in such applications, it is necessary to increase the thickness of the film in order to improve gas barrier properties, and lamination is generally performed using adhesives such as urethane adhesives or aqueous polyvinyl alcohol solutions. However, such lamination methods require steps such as coating and drying the adhesive, which also adds to the cost of the adhesive. Therefore, a heat sealing method may be considered, but polyvinyl alcohol resins generally have a high melting point of 200°C or higher, and even if they can be temporarily laminated at low temperatures, they have the disadvantage of easily causing interfacial peeling.
Ultimately, high gas barrier properties cannot be ensured.

Moreover, it is an object of the present invention to provide a method for producing a PVA film laminate that ensures a high level of gas barrier properties in terms of adhesiveness. [Means for Solving the Problems] In order to produce a PVA film laminate that achieves the object of the present invention, when polyvinyl alcohol resin films are laminated together, at least one, preferably both resin films are hydrated or This is carried out by moistening with a water-polyol mixture and heating to a softened state and then press-bonding.

。(1) Casting method Generally, polyvinyl alcohol resin concentration is about 5 to 60%,
Preferably, about 10 to 40% of the film-forming stock solution is cast onto a rotary drying drum (roll) or belt through a slit or coated with a roll coater, and the polyvinyl alcohol resin immediately after the film is cast in this manner. Since the film-like material contains moisture and is softened by heating, the film-like material is pressed as is.
この際、フィルム状物同士をこのようにして圧着させる
ことが好ましいが、一方の樹脂フィルム上に製膜原液を
フィルム状に流延し、圧着させることもできる。At this time, it is preferable to pressure-bond the film-like materials to each other in this manner, but it is also possible to cast the film-forming stock solution onto one of the resin films in the form of a film and pressure-bond them.

％の割合で用いられる。When carrying out these methods, polyvinyl alcohol with a high degree of saponification is difficult to dissolve in water unless the temperature is high, so a certain amount of heating is required, and in order to control the rapid evaporation of water at high temperatures. Polyols, which are also used as softeners, are added to water and wetted with such water-polyol mixtures. As the polyol, ethylene glycol, diethylene glycol, propylene glycol, glycerin, etc. are used. The higher the proportion of these used, the easier it is to control at high temperatures, but considering not only cost but also flexibility, gas barrier properties, etc. , preferably in a proportion of about 20 to 150% by weight.
圧着は、約５０〜１８０℃、好ましくは約７０〜１２０
℃の温度で、熱プレス、加熱ロール，ヒートシーラなど
を用いて、全面的または部分的に行われる。Crimping is performed at about 50-180°C, preferably about 70-120°C.
It is carried out in whole or in part at a temperature of °C using a heat press, a heat roll, a heat sealer, etc.

圧着させると、しわやエア入り部分が生じ難い。By using a pair of roll-shaped heat sealers, it is also possible to partially laminate bags and deep-drawn articles. Also,
When laminating the entire surface using a hot press, crimp and air-filled areas are less likely to occur if the layers are bonded under reduced pressure.
本発明方法によれば，ポリビニルアルコール系樹脂フィ
ルムを含水かつ加熱軟化状態で圧着するだけで樹脂フィ
ルムを積層させることができ，工程的、コスト的にすぐ
