<p>Abstract It is intended to keep the plastic films from being peeled off from each other at a concerned joining portion. 5 A composite film Co is composed of external and internal films 1 and 2 opposed to and superposed with each other, to have opposite end portions 3. The composite film Co is opposed to and superposed with an additional body Ad. The method includes joining the external and internal films 1 10 and 2 and the additional body Ad with each other at one of the end portions 3 so that a first joining portion 4 should be formed between the external and internal films 1 and 2, a second joining portion 5 being formed between the internal film 2 and the additional body Ad. The first 15 joining portion 4 has a first joining width W1 and includes first outer and inner edges El and El' formed by the first joining width W1. The second joining portion 5 has a second joining width W2 and includes second outer and inner edges E2 and E2' formed by the second joining 20 width W2. The method comprises making an adjustment of the first or second joining width W1 or W2, the first joining width W1 being less than the second joining width W2 so that the first inner edge El' should be formed outwardly of the second inner edge E2'. 4856091 1 (GHMatters) P95419.AU 11/11/13</p> |
