摘要：
A method for joining films having a hydrophilized surface at a single surface and an excellent melt-bonding force at the melt-bonded portion, which is formed by disposing two films (A) having a hydrophilized surface at a single surface, to align the hydrophilized surfaces so as to butt each end portion; overlaying a film (B) on a side of non-hydrophilized surface of the films (A), so as to bridge the butting portion, and hot-pressing the overlapping portion (c1)5 to join the two films (A). A wide film obtained by the above-mentioned method is suitable for a covering material for agricultural use.
