<p>A method of splicing laminated films, comprising the steps of splicing extended base film layers (3, 4) to each other in a principal rafter shape at a connection part between the rear end portion and top end portion of the laminated films (1, 2) having the extended base film layers (3, 4) and sealant layers (5, 6) to make the interconnected part of the laminated films sufficiently contribute to the manufacture of a packaging bag and provide excellent airtightness and sealability to the connection part itself, and providing a tensile strength necessary for the laminated films to the connection part to eliminate the need of temporary stop of a packaging device when the connection part of the laminated films passes the packaging device so as to increase a working capability and a working efficiency and also increase the yielding of material.</p> |
