<p>PURPOSE:To obtain a laminated sheet capable of completely dissolving and removing a polyalkyleneoxide film from the laminated sheet consisting of water soluble polyalkyleneoxide film and foreign material. CONSTITUTION:In the instance of laminating polyalkyleneoxide film 2 consisting mainly of an ethyleneoxide component with a foreign material 1, lamination is effected for the polyalkyleneoxlde film and foreign material via water therebetween. In this case, water is suitable to be employed in the form of sprinkled water particle 91. As a consequence of the foregoing method, the dissolving and removing of polyalkyleneoxide film is completely conducted by the use of water in comparison with a method of lamination conducted in use of an adhesive or the like.</p> |
